the queue than the subject application for interconnection. The identified
contingent upgrades are required in order for the applicant's proposed
interconnection request to receive permission to operate and, if delayed or not
built by the earlier-queued interconnection request, could cause a need for
restudies of the interconnection request and may become the responsibility of
the applicant's interconnection request.
"Distributed energy resources
facility" or "DER" facility means the equipment used by an
interconnection customer to generate or store electricity that operates in
parallel with the electric distribution system. A DER facility may include,
but is not limited to, an electric generator or energy storage system, a prime

b) Using
the information provided in the pre-application report request form described
in subsection (a), the EDC will identify the distribution facilities that are
likely to serve the proposed point of interconnection if the project is
constructed, including: substation/area bus, substation transformer or
distribution circuit, as applicable. This identification by the EDC does not
guarantee, after application of the relevant review process, that the EDC will
use the distribution facilities identified in the pre-application report to
connect to the project. The potential applicant must request additional pre-application
reports if information about multiple points of interconnection is requested.
Subject to subsection (c), the pre-application report shall include the
following information:
1) Identification of up to two distribution
circuits within one quarter mile of the proposed point of interconnection,
including the following information:

ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES
SECTION 466.60 GENERAL REQUIREMENTS
Section 466.60 General Requirements
a) When
an interconnection request for a DER facility includes multiple energy
production devices at a site for which the applicant seeks a single point of
interconnection, the interconnection request shall be evaluated based on the
aggregate nameplate capacity of the multiple devices. Where the export
capacity is limited through acceptable means as defined in Section 466.75, the
EDC shall evaluate only the aggregate export capacity for certain impacts as
specified in the screening and study provisions.
b) When
an interconnection request is for an increase in capacity for an existing DER
facility, the interconnection request shall be evaluated based on the incremental
impact of the new total nameplate capacity of the DER facility. Where the
export capacity is limited through acceptable means as defined in Section 466.75,
the EDC shall evaluate only the aggregate export capacity for certain impacts
as specified in the screening and study provisions.
c) EDCs
shall publish on their websites a dedicated email address and phone number as a
point of contact. The point of contact shall be able to direct applicant
questions concerning interconnection request submissions and the
interconnection request process to knowledgeable individuals within the EDC.
d) The
information that the EDC makes available to potential applicants can include
previously existing EDC studies that help applicants understand whether it is
feasible to interconnect a DER facility at a particular point on the EDC's
electric distribution system. The EDC may require a confidentiality agreement
prior to release of this information. However, the EDC can refuse to provide
the information to the extent that providing it violates security requirements
or confidentiality agreements, or it is contrary to law or State or federal
regulations.
e) The
EDC shall deem an interconnection request complete when the applicant submits
completed forms.
f) When
an applicant is not currently a customer of the EDC at the proposed site, the
applicant shall provide, at the time of the interconnection request, proof of the
applicant's legal right to control the site, evidenced by the applicant's name
on a property tax bill, deed, lease agreement, option agreement, or other
legally binding contract.
g) An
interconnection request shall be processed in accordance with Sections
466.90(b)(2), 466.100(b)(2), 466.110(a)(2), and 466.120(b) of this Part.
h) To
minimize the cost to interconnect multiple DER facilities, the EDC or the
applicant may propose a single point of interconnection for multiple DER
facilities located at an interconnection customer site that is on contiguous
property. If the applicant rejects the EDC's proposal for a single point of
interconnection, the applicant shall pay any additional cost to provide a
separate point of interconnection for each DER facility. If the EDC, without
written and detailed technical explanation, rejects the customer's proposal for
a single point of interconnection, the EDC shall pay any additional cost to
provide separate points of interconnection for each DER facility. Any disagreement over who bears the cost for providing
separate points of interconnection shall be resolved in accordance with Section
466.130.
i) To
protect the safety of the EDC's employees or the reliability of the
distribution system, EDCs may require that DER facilities have the capability
to be isolated from the electric distribution system. For DER facilities
interconnecting to a primary line, the isolation shall be by means of a
lockable, visible-break isolation device accessible by the EDC. For DER
facilities interconnecting to a secondary line, the isolation shall be by means
of a lockable isolation device whose status is indicated and is accessible by
the EDC. For DER facilities interconnecting to a secondary line through a
self-contained meter, the EDC's removal of the self-contained electric meter
may satisfy this capability. The isolation device shall be installed, owned
and maintained by the owner of the DER facility and located electrically
between the DER facility and the point of interconnection. A draw-out type of circuit
breaker accessible to the EDC with a provision for padlocking at the drawn-out
position satisfies the requirement for an isolation device.
j) The
interconnection customer shall allow the EDC to isolate the DER facility. An
interconnection customer may elect to provide the EDC with access to an
isolation device that is contained in a building or area that may be unoccupied
and locked or not otherwise accessible to the EDC by installing a lockbox
provided by the EDC that allows ready access to the isolation device. The
lockbox shall be in a location determined by the EDC to be accessible by the
EDC. The interconnection customer shall permit the EDC to affix a placard in a
location of its choosing that provides instructions to EDC operating personnel
for accessing the isolation device. If the EDC needs to isolate the distribution
generation facility, the EDC shall not be held liable for any damages resulting
from the actions necessary to isolate the generation facility.
k) Any
metering required for a DER interconnection shall be installed, operated, and
maintained in accordance with applicable EDC tariffs and agreements. Any such
metering requirements shall be identified in the standard DER interconnection
agreement executed between the interconnection customer and the EDC.
l) EDC
monitoring and control of DER facilities are permitted only when the nameplate capacity
is greater than 2 MVA or for a DER facility with a nameplate capacity equal to
or less than 2 MVA when the EDC determines, and the applicant agrees, that such
monitoring and control could be used to mitigate impacts from the project that
may otherwise require an upgrade or would otherwise be useful or beneficial. Monitoring
and control requirements shall be consistent with the EDC's published
requirements and shall be clearly identified in the interconnection agreement
between the interconnection customer and the EDC. Transfer trip shall not be
considered EDC monitoring and control when required and installed to protect
the electric distribution system or an affected system against adverse system
impacts. However, transfer trip, if required, shall be clearly identified in
the interconnection agreement between the interconnection customer and the EDC.
m) The
EDC may require a witness test after the DER facility is constructed. The
applicant shall provide the EDC with at least 15 business days' notice of the
planned commissioning test for the DER facility, unless
otherwise agreed by the EDC and applicant. The applicant and EDC shall
schedule the witness test at a mutually agreeable time. If the witness test results
are not acceptable to the EDC, the applicant shall be granted 30 business days
to address and resolve any deficiencies. The time period for addressing and
resolving any deficiencies may be extended upon the mutual agreement of the EDC
and the applicant prior to the end of the 30 business days. The EDC shall not
deny an initial request for extension. Subsequent requests may be denied only if there are applicants later in the queue that would
be impacted by additional delays. If the applicant fails to address and
resolve the deficiencies to the EDC's satisfaction, the EDC may deem the
interconnection request withdrawn. Even if the EDC or an entity approved by

ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES
SECTION 466.75 LIMITED-EXPORT AND NON-EXPORTING DISTRIBUTION ENERGY RESOURCES FACILITIES
Section
466.75 Limited-Export and Non-Exporting Distribution Energy Resources
Facilities
The following technical specifications are
intended to identify acceptable export control methods to facilitate the
interconnection and parallel operation of limited-export and non-export systems
with the EDC's electric distribution system.
a) If a DER facility
uses any configuration or operating mode in subsections (c)(1) through (6) to limit the
export of electrical power across the point of interconnection, then the export
capacity shall be only the amount capable of being exported (not including any
inadvertent export). To prevent impacts on system safety and reliability, any
inadvertent export from a DER facility must comply with the limits identified
in this Section. The export capacity specified by the interconnection customer
in the application will subsequently be included as a limitation in the
interconnection agreement. Applicants seeking to interconnect using the
operating modes under this Section shall submit proposed control or protection
settings in their application for review by the EDC to verify compliance with
the requirements of this Section.
b) The export
control types and settings listed in subsection (c) are acceptable for
controlling export capacity unless the EDC identifies and communicates to the
customer during the interconnection screening or study process specific impacts
that affect the reliability, safety, operation and power quality of the EDC's
system associated with the protection relays, settings and control schemes
listed in this Section. In that case, the EDC may identify alternate settings
that would be required for safe and reliable interconnection of the proposed DER
facility. The EDC may also identify any monitoring and control equipment to be
installed at Applicant’s expense on DER systems using export control equipment
that is required for safe and reliable interconnection and operation of the DER
facility.
c) The export
controls identified in subsections (c)(1) through (3) are acceptable for
non-exporting systems only. The export control identified in subsections (c)(4)
and (c)(5) may be used for limited export systems only. The export controls in subsections
(c)(6) and (7) may be used for either non-exporting or limited export systems.
Inverter-based limited export systems shall use advanced inverters utilizing
operating modes and settings specified by the EDC in its written technical
standards for interconnection.
1) Reverse Power
Protection (Device 32R)
To limit export of power across the point
of interconnection, a reverse power protective function is implemented using a
utility-grade protective relay. The default setting for this protective
function shall be 0.1% (export) of the service transformer's nominal base
nameplate rating, with a maximum 2.0 second time delay to limit inadvertent
export.
2) Minimum Power
Protection (Device 32F)
To limit export of power across the point
of interconnection, a minimum import protective function is implemented using a
utility-grade protective relay. The default setting for this protective
function shall be 5% (import) of the generating unit's total nameplate
capacity, with a maximum 2.0 second time delay to limit inadvertent export.
3) Relative Distributed
Energy Resource Rating
This option requires the DER facility's
nameplate capacity to be so small in comparison to its host facility's minimum
load that the use of additional protective functions is not required to ensure
that power will not be exported to the electric distribution system. This
option requires the DER facility's nameplate capacity to be no greater than 50%
of the interconnection customer's verifiable minimum host load over the past 12
months. For systems above 250 kVA, the EDC
may require additional assurances, equipment, or agreements based upon
evaluation of the stability and reliability of the minimum load data. This
option is not available for interconnections to area networks or spot networks.
4) Directional Power
Protection (Device 32)
To limit export of power across the point
of interconnection, a directional power protective function is implemented
using a utility-grade protective relay. The default setting for this protective
function shall be the export capacity value, with a maximum 2.0 second time
delay to limit inadvertent export.
5) Configured Power
Rating
A reduced output power rating utilizing
the power rating configuration setting may be used to ensure the DER does not
generate power beyond a certain value lower than the nameplate capacity. The
reduced power rating shall be indicated by means of a nameplate rating replacement,
or by a supplemental adhesive nameplate rating tag to indicate the reduced
nameplate rating. At the discretion of the EDC, the applicant may additionally
be required to provide a letter from the manufacturer confirming the reduced
capacity.
6) Limited Export
Utilizing Power Control Systems
The following are the minimum
requirements for the limited export utilizing power control systems that meet
the criteria specified in this subsection (c)(6). Other factors relevant to the
interconnection study process may necessitate additional technical requirements
that are not explicitly noted in this subsection. This option is not available
for interconnections to area networks or spot networks.
A) DER
facilities utilizing this option must use an NRTL-certified UL 1741 power
control system and inverter system with a maximum open loop response time of no
more than 30 seconds for systems less than or equal to 100 kVA and a maximum
open loop response time of no more than 10 seconds for systems greater than 100
kVA. The DER facility must disconnect from the electric distribution system,
ceasing to energize the electric system or halting energy production within 2.0
seconds if the period of continuous export exceeds 30.0 seconds.
B) Failure of
the control system or inverter system for more than 30.0 seconds resulting from
loss of control or measurement signal, loss of control power, single component
failure, or related control sensing of the control circuitry must result in the
DER facility entering non-export operation mode whereby no energy is exported
across the point of interconnection to the electric distribution system until
the customer has reestablished real power output control of the DER facility.
C) An acceptable
open loop response time may need to be mutually agreed upon between the EDC and
the applicant for DER facilities with a nameplate capacity greater than 1 MVA
that utilize a NRTL certified power control system.
COMMISSION NOTE:
NRTL testing to the UL power control system certification requirements decision
shall be accepted until similar test procedures for power control systems are
included in a standard.
7) Limited Export
Using Agreed-Upon Means
DER facilities may be designed with other
control systems or protective functions to limit export and inadvertent export
if mutual agreement is reached with the EDC. The limits may be based on
technical limitations of the interconnection customer's equipment or the
electric distribution system equipment. To ensure inadvertent export remains
within mutually agreed-upon limits, the interconnection customer may use an
uncertified power control system, an internal transfer relay, energy management
system, or other customer facility hardware or software if approved by the EDC.

certificate of completion (see Appendix B) has been returned to the EDC. Completion
of local inspections may be designated on inspection forms used by local
inspecting authorities;
C) The
witness test has been successfully completed if required by the EDC or if the
witness test has been waived according to of Appendix A(2)(c)(ii); and
D) The
applicant has signed a standard DER interconnection agreement (see Appendix A).
When an applicant does not sign the agreement within 30 business days after
receipt of the agreement from the EDC, the interconnection request is deemed
withdrawn unless the applicant requests to have the deadline extended for no
more than 15 business days. An initial request for extension shall not be
denied by the EDC, but subsequent requests may be denied. In order to withdraw
a standard DER interconnection agreement, the EDC must first send a
notification to the applicant of its intent to withdraw, and the applicant must
not have sent an executed standard DER interconnection agreement within 5
business days after receipt of the notice.
6) If the EDC
determines and demonstrates that a DER facility does not pass all relevant
Level 1 screens, the EDC shall provide a letter to the applicant explaining the
reasons that the facility did not pass those screens.

PART 466
ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES
SECTION 466.100 LEVEL 2 EXPEDITED REVIEW
Section 466.100 Level 2 Expedited Review
An EDC shall use the Level 2 review procedure for
interconnection requests that meet the Level 2 criteria in Section 466.80(b). An
EDC may not impose additional requirements for Level 2 reviews that are not
specifically authorized under this Section unless the applicant agrees.
a) The
EDC shall evaluate the potential for adverse system impacts using the following
screens, which shall be satisfied:
1) Until
December 31, 2023, for interconnection of a proposed DER facility to a radial
distribution circuit, the aggregate export capacity of the DER facilities connected
to the distribution circuit, including the proposed DER facility, may not
exceed 100% of the minimum load (or 15% of the maximum load if minimum data are
unavailable) normally supplied by the distribution circuit or line section. After
December 31, 2023, for interconnection of a proposed DER facility to a radial
distribution circuit, the aggregate export capacity of the DER facilities
connected to the distribution circuit, including the proposed DER facility, may
not exceed 100% of the minimum load normally supplied by the distribution
circuit or line section.
2) For
interconnection of a proposed DER facility to the load side of spot network
protectors, the proposed DER facility shall utilize an inverter-based equipment
package. The customer interconnection equipment proposed for the DER facility
must be lab-certified and, when aggregated with other generation, the nameplate
capacity may not exceed 5% of a spot network's maximum load.
3) The
proposed DER facility, in aggregate with other generation on the distribution
circuit, may not contribute more than 10% to the distribution circuit's maximum
fault current at the point on the primary line nearest the point of
interconnection.
4) The
proposed DER facility, in aggregate with other generation on the distribution
circuit, shall not cause any distribution protective devices and equipment
including substation breakers, fuse cutouts, and line reclosers, or other
customer equipment on the electric distribution system to be exposed to fault
currents exceeding 90% of their short circuit interrupting capability. However,
if fault currents exceed 100% of the EDC's equipment short circuit interrupting
capability even without the DER being interconnected, the EDC shall replace the
equipment at its own expense, and interconnection may proceed under Level 2.
5) When
a customer-generator facility is to be connected to 3-phase, 3-wire primary EDC
distribution lines, a 3-phase or single-phase generator shall use a
phase-to-phase primary connection. This screen does not apply to DER
facilities with a nameplate capacity below 11 kVA.
6) When
a customer-generator facility is to be connected to 3-phase, 4-wire primary EDC
distribution lines, a 3-phase or single-phase generator shall use a grounded
line-to-neutral primary connection. This screen does not apply to DER
facilities with a nameplate capacity below 11 kVA.
7) When
the proposed DER facility is to be interconnected on single-phase shared
secondary line, the aggregate export capacity on the shared secondary line,
including the proposed DER facility, may not exceed 20 kVA. In the instance
where the proposed DER facility is below 100 kVA and uses acceptable means for
controlling export as set forth in Section 466.75, the export capacity of the
proposed DER facility will be used.
8) When
a proposed DER facility is single-phase and is to be interconnected on a center
tap neutral of a 240 volt service, its addition may not create an imbalance
between the two sides of the 240 volt service of more than 20% of the nameplate
kVA rating of the service transformer.
9) The
nameplate capacity of a DER facility, in aggregate with other DER facilities'
nameplate capacity interconnected to the distribution side of a substation
transformer feeding the circuit where the DER facility proposes to
interconnect, may not exceed 10 MVA in an area where there are known or posted
transient stability limitations to generating units located in the general
electrical vicinity.
b) The Level 2
interconnection shall use the following procedures:
1) The
applicant submits an interconnection request using the appropriate form and the
Level 2 application fee (see Appendix C).
2) Within
10 business days after receiving the interconnection request, the EDC shall
inform the applicant as to whether the interconnection request is complete. If
the request is incomplete, the EDC shall specify what materials are missing and
the applicant has 10 business days to provide the missing information or the
interconnection request shall be deemed withdrawn.
3) After
an interconnection request is deemed complete, the EDC shall assign a queue
position based upon the date that the interconnection request is determined to
be complete. The EDC shall then inform the applicant of its queue position.
4) If,
after determining that the interconnection request is complete, the EDC determines
that it needs additional information to evaluate the DER facility's adverse
system impact, it shall request this information. The EDC may not restart the
review process or alter the applicant's queue position because it requires the
additional information. The EDC can extend the time to finish its evaluation
only to the extent of the delay required for receipt of the additional
information. In order to withdraw an interconnection request, the EDC must
first send a notification to the applicant of its intent to withdraw, and the
applicant must not have sent the information requested by the EDC within 5
business days after receipt of the notice.
5) Within
20 business days after the EDC notifies the applicant it has received a
completed interconnection request, the EDC shall:
A) Evaluate
the interconnection request using the Level 2 screening criteria.
B) Provide
the applicant with the EDC's evaluation, including a written technical
explanation. If one or more screens are not passed, the EDC shall provide, in
writing, the specific screens that the application failed, including the
technical reason for failure. The EDC shall provide information and detail
about the specific system threshold or limitation causing the application to
fail the screen. If an EDC does not have a record of receipt of the
interconnection request and the applicant can demonstrate that the original
interconnection request was delivered, the EDC shall expedite its review to
complete the evaluation of the interconnection request within 20 business days
after the applicant's demonstration.
c) When
an EDC determines that the interconnection request passes the Level 2 screening
criteria contained in subsection (a), the interconnection request passes the
Supplemental Review contained in subsection (f), or the EDC determines that the
DER facility can be interconnected safely and will not cause adverse system
impacts, even if it fails one or more of the Level 2 screening criteria, it
shall provide the applicant with a standard DER interconnection agreement (see
Appendix D) within the following timeframes:
1) If the proposed
interconnection requires no construction of facilities by the EDC on its own
system, the interconnection agreement shall be provided within 5 business days
after the notification of Level 2 review results.
2) If the proposed
interconnection requires only minor system modifications, the EDC shall notify
the applicant of the required minor system modifications when it provides the
Level 2 results. The applicant must inform the EDC if the applicant elects to
continue the application and pay the fee specified in the EDC's tariff. If the
applicant makes such an election, the EDC shall provide to the applicant the
interconnection agreement, along with a non-binding good faith cost estimate
and construction schedule for the required upgrades within 30 business days
after the EDC receives such an election and the payment of the fee.
3) If
the proposed interconnection requires more than minor system modifications, the
EDC shall notify the applicant of that requirement when it provides the Level 2
or supplemental review results. The applicant must inform the EDC if the
applicant elects to continue the application. If the applicant makes such an
election, the EDC may elect to:
A) provide
a standard DER interconnection agreement (see Appendix D), along with a
non-binding good faith cost estimate and construction schedule for the required
upgrades within 45 business days after the EDC receives such an election and
the applicant pays the fee specified in the EDC's tariff; or
B) notify
the applicant that an interconnection facilities study under Section
466.120(e)(3) must be performed to determine the necessary upgrades. If the
applicant elects to proceed with an interconnection facilities study, the EDC
shall proceed with the interconnection facilities study according to the
timeframes and process in Section 466.120(e)(3).
d) Within
30 business days after receipt of the standard DER interconnection agreement,
the applicant shall sign and return the agreement to the EDC. If the applicant
does not sign and return the agreement within 30 business days, the
interconnection request shall be deemed withdrawn unless the applicant requests
a 15-business-day extension in writing. The initial request for extension may
not be denied by the EDC. When the EDC constructs an additional review under
the provisions of subsection (f), the interconnection of the DER facility shall
proceed according to milestones agreed to by the parties in the standard DER
interconnection agreement.
e) The DER
facility is not permitted to operate until:
1) All
requirements in the standard DER interconnection agreement are satisfied;
2) The DER
facility is approved by the electric code officials with jurisdiction over the
interconnection;
3) The
applicant provides a certificate of completion (see Appendix B) to the EDC.
Completion of local inspections may be designated on inspection forms used by
local inspecting authorities; and
4) The
witness test is successfully completed if required by the EDC or if the witness
test is waived according to Article 2.1.1 of Appendix D.
f) When
a DER facility fails to meet one or more of the Level 2 screens contained in subsection
(a), the EDC shall provide the applicant the opportunity to amend its
application one time to address the screen failure and offer to perform a supplemental
review in accordance with the following subsections and provide the applicant
with a non-binding estimate for the costs of the supplemental review. If the
applicant chooses to amend the application to address the specific screens that
failed, the applicant must submit updated application materials demonstrating
the redesign within 10 business days after receiving the screen results from
the EDC. If the applicant chooses to have a supplemental review performed, the EDC
shall undertake the supplemental review only after the applicant pays for the supplemental
review.
1) If
the applicant accepts the offer of a supplemental review, the applicant shall
agree in writing and pay the amount of the EDC's good faith estimate of the
costs of that review, both within 15 business days after the offer. If the
written agreement and payment have not been received by the EDC within that
timeframe, the interconnection request shall be considered withdrawn by the applicant.
2) The applicant
may specify the order in which the EDC will complete the screens in this Section.
3) The applicant
shall be responsible for the EDC's actual costs for conducting the supplemental
review. The applicant must pay any additional costs that exceed the good faith
estimate within 20 business days after receipt of the invoice or resolution of
any dispute. If the initial payment exceeds the invoiced actual costs, the EDC
will return that excess within 20 business days after the invoice without
interest.
4) Within
30 business days following receipt of the payment for a supplemental review,
the EDC shall perform a supplemental review using the screens set forth in this
subsection (f)(4); notify in writing the applicant of the results; and include
with the notification copies of the analysis and data underlying the EDC's
determinations under the screens.
A) Minimum Load Screen
When 12
months of line section minimum load data (including onsite load but not station
service load served by the proposed DER facility) are available, the aggregate export capacity of the generating
facility on the line section is less than 100% of the minimum load for all line
sections bounded by automatic sectionalizing devices upstream of the proposed DER
facility. If minimum load data is not available, the EDC shall include the
reasons that it is unable to determine minimum load in its supplemental review
results notification under this Section. This
screen does not apply to non-exporting systems or those that are proposing to
add no new export capacity.
i) The type of generation used by the proposed DER
facility will be taken into account when determining circuit or line section
minimum load relevant to the application of this screen. Solar PV generation
systems with no energy storage use daytime minimum load (i.e., 10 a.m. to 4
p.m. for fixed panel systems and 8 a.m. to 6 p.m. for PV systems utilizing
tracking systems), while all other generation uses absolute minimum load. The EDC shall apply this screen using the operating profile
and system design designated in the interconnection request and accompanying
attachments. For example, the EDC shall evaluate the maximum export capacity
during the hours of the day designated by the customer as operational and shall
take into account any export controls.
ii) Only the net injection into the EDC's electric
system will be considered as part of the aggregate export capacity. In the instance where the proposed DER facility uses
acceptable means for controlling export as set forth in Section 466.75, only
the net power injection into the EDC's electric system will be considered as
part of the aggregate export capacity.
iii) For evaluating this screen, the EDC will not
include as part of the aggregate export
capacity any existing DER facility export
capacity already reflected in the minimum load data.
B) Voltage and Power Quality Screen
The
project, considered in aggregate with existing generation, must meet the
following requirements: the voltage regulation can be maintained in compliance
with relevant requirements under all system conditions; the voltage fluctuation
is within the EDC's acceptable limits; and the harmonic levels meet limits
recommended by IEEE Standard 519-2014: Recommended Practice and Requirements for Harmonic Control in Electric Power
Systems.
C) Safety and Reliability Screen
The
location of the proposed DER facility and the aggregate generation capacity on
the line section do not create impacts to safety or reliability that cannot be
adequately addressed without application of the Level 4 process. The EDC shall
give due consideration to the following and other factors in determining
potential impacts to safety and reliability in applying this screen:
i) whether the line section has significant
minimum loading levels dominated by a small number of customers (e.g., several
large commercial customers);
ii) whether the loading along the line section is
uniform or even;
iii) whether the proposed DER facility is located
in close proximity to the substation (i.e., less than 2.5 electrical circuit
miles), and whether the line section from the substation to the point of interconnection
is a main line rated for normal and emergency ampacity;
iv) whether the proposed DER facility incorporates
a time delay function to prevent reconnection of the generator to the system
until system voltage and frequency are within normal limits for a prescribed
time;
v) whether operational flexibility is reduced by
the proposed DER facility, such that transfer of the line section of the DER
facility to a neighboring distribution circuit/substation may trigger overloads
or voltage issues; and
vi) whether the proposed DER facility employs
equipment or systems certified by a nationally recognized testing laboratory
(NRTL) to address technical issues such as, but not limited to, islanding,
reverse power flow or voltage quality.
5) If
the proposed interconnection passes the supplemental review screening in this Section,
the EDC shall provide the applicant with an executable interconnection
agreement pursuant to subsections (c), (d) and (e).
g) If
the DER facility is not approved under a Level 2 review, the EDC shall provide
the applicant with written notification explaining its reasons for denying the
interconnection request. The EDC shall specify which screens the application
failed, including the technical reason for failure, and the data and the
analysis supporting the supplemental review. The EDC shall provide information
and detail about the specific system threshold or limitation, preventing
determination of required system modification without further study. If the
applicant chooses to revise the application to address the specific screens
that failed, the customer must submit updated application materials
demonstrating the redesign within 10 business days after receiving the review results
from the EDC and pay an additional review cost. However, this redesign shall
not include an increase in export capacity and shall not include a change in
the proposed location of the DER facility. Increases in export capacity or
changes in facility location shall require a new interconnection request and
associated fees. The EDC will evaluate whether the redesign addresses the
screen failure and provide the applicant the results of this evaluation in 10
business days. This option shall only be available one time during the
screening phase of the Level 2 process.
h) If
the applicant chooses not to redesign the project or the redesign does not
result in passage of the screens, the applicant may submit a new
interconnection request for consideration under a Level 4 interconnection
review. The queue position assigned to the Level 2 interconnection request shall
be retained, provided that the new interconnection request is made by the
applicant within 15 business days after notification that the current
interconnection request is denied.

PART 466
ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES
SECTION 466.110 LEVEL 3 EXPEDITED REVIEW
Section 466.110 Level 3 Expedited Review
An EDC shall use the Level 3 expedited review procedure for
an interconnection request that meets the criteria in Section 466.80(c). An EDC
may not impose additional requirements for Level 3 reviews not specifically
authorized under this section unless the applicant agrees.
a) A Level 3
interconnection shall use the following procedures:
1) The
applicant submits an interconnection request using the appropriate form and the
Level 3 application fee (see Appendix C).
2) Within
10 business days after receiving the interconnection request, the EDC shall
inform the applicant as to whether the interconnection request is complete. If
the request is incomplete, the EDC shall specify what materials are missing and
the applicant has 10 business days to provide the missing information, or the
interconnection request shall be deemed withdrawn.
3) After
an interconnection request is deemed complete, the EDC shall assign a queue
position to it based upon the date the interconnection request is determined to
be complete. The EDC shall then inform the applicant of its queue position.
4) If,
after determining that the interconnection request is complete, the EDC
determines that it needs additional information to evaluate the DER facility's
adverse system impact, it shall request this information. The EDC may not
restart the review process or alter the applicant's queue position because it
requires the additional information. The EDC can extend the time to finish its
evaluation only to the extent of the delay is required for receipt of the
additional information. If the applicant does not provide this additional
information within 15 business days, the EDC may deem the interconnection
request withdrawn.
5) Interconnection
requests meeting the requirements set forth in Section 466.80(c)(1) for
non-exporting DER facilities interconnecting to an area network shall be
presumed to be appropriate for interconnection. The EDC shall process the
interconnection request to area networks using the following procedures:
A) The EDC
shall evaluate the interconnection request under Level 2 interconnection review
procedures as set forth in Section 466.100(a) except that the EDC has 25
business days to evaluate the interconnection request against the screens to
determine whether interconnecting the DER facility to the EDC's area network
has any potential adverse system impacts. In applying the Level 2 screens set
forth in Section 466.100(a) for projects on area networks, the EDC may evaluate
the proposed DER facility using nameplate capacity and not the export capacity
for screens 1 and 7 if it determines that is appropriate.
B) If the
Level 2 screens for area networks identify potential adverse system impacts,
the EDC may determine, at its sole discretion, that it is inappropriate for the
DER facility to interconnect to the area network under Level 3 review, and the
interconnection request is denied. The applicant may submit a new
interconnection request for consideration under Level 4 procedures at the queue
position assigned to the Level 3 interconnection request, if the new
interconnection request is made within 15 business days after notification that
the current application is denied.
6) For
interconnection requests that meet the requirements of Section 466.80(c)(2) for
non-exporting DER facilities interconnecting to a radial distribution circuit,
the EDC shall evaluate the interconnection request under the Level 2 expedited
review in Section 466.100(a).
b) For a
DER facility that satisfies the criteria in Section 466.110(a)(5) or (a)(6),
the EDC shall approve the interconnection request and provide a standard
interconnection agreement (see Appendix D) for the applicant to sign within the
following timeframes:
1) If the proposed
interconnection requires no construction of facilities by the EDC on its own
system, the interconnection agreement shall be provided within 5 business days
after the notification of Level 3 review results.
2) If the proposed
interconnection requires only minor system modifications, the EDC shall notify
the applicant of that requirement when it provides the Level 3 results. The
applicant must inform the EDC if the applicant elects to continue the
application and pay the fee specified in the EDC's tariff. If the applicant
makes such an election, the EDC shall provide the interconnection agreement,
along with a non-binding good faith cost estimate and construction schedule for
those upgrades, to the applicant within 30 business days after the EDC receives
such an election and the payment of the fee.
3) If
the proposed interconnection requires more than minor system modifications, the
EDC shall notify the applicant of that requirement when it provides the Level 3
results. The applicant must inform the EDC if the applicant elects to proceed
with the interconnection. If the applicant makes such an election, the EDC may
elect to:
A) provide
a standard DER interconnection agreement (see Appendix D), along with a
non-binding good faith cost estimate and construction schedule for those
upgrades within 45 business days after the EDC receives such an election and
the applicant pays the fee specified in the EDC's tariff; or
B) notify
the applicant that an interconnection facilities study must be performed pursuant
to Section 466.120(e)(3). If the applicant elects to proceed with an
interconnection facilities study, the EDC shall proceed with the
interconnection facilities study according to the timeframes and process in
Section 466.120(e)(3).
c) Within
30 business days after receipt of the standard DER interconnection agreement,
the applicant shall complete, sign and return the agreement to the EDC. If the
applicant does not sign the standard DER interconnection agreement within 30
business days, the request shall be deemed withdrawn, unless the applicant
requests a 15 business day extension in writing. An initial request for
extension may not be denied by the EDC. After the standard DER interconnection
agreement is signed by the parties, interconnection of the DER facility shall
proceed according to any milestones agreed to by the parties in the standard DER
interconnection agreement.
d) The DER
facility is not permitted to operate until:
1) All
requirements in the interconnection agreement are satisfied;
2) The DER
facility is approved by the electric code officials with jurisdiction over the DER
facility;
3) The
applicant provides a certificate of completion (see Appendix B) to the EDC; and
4) The
witness test is successfully completed, if required by the EDC or if the
witness test is waived according to Article 2.1.1 of Appendix D.
e) If
the DER facility is not approved under a Level 3 review, the EDC shall provide
the applicant with written notification explaining its reasons for denying the
interconnection request. The applicant may submit a new interconnection
request for consideration under a Level 4 interconnection review. The queue
position assigned to the Level 3 interconnection request shall be retained,
provided that the new interconnection request is made within 15 business days
after notification that the current interconnection request is denied.

ADMINISTRATIVE CODE TITLE 83: PUBLIC UTILITIES CHAPTER I: ILLINOIS COMMERCE COMMISSION SUBCHAPTER c: ELECTRIC UTILITIES PART 466 ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES SECTION 466.120 LEVEL 4 REVIEW
Section 466.120 Level 4 Review
An EDC shall use the Level 4 study review procedures for an
interconnection request that meets the criteria in Section 466.80(d).
a) The
applicant submits an interconnection request using the appropriate form, along
with the Level 4 application fee (see Appendix C).
b) Within
10 business days after receipt of an interconnection request, the EDC shall
notify the applicant whether the request is complete. When the interconnection
request is not complete, the EDC shall provide the applicant with a written
list detailing the information required to complete the interconnection
request. The applicant has 10 business days to provide the required information
or the interconnection request is considered withdrawn. The parties may agree
to extend the time for receipt of the additional information. The
interconnection request is deemed complete when the applicant has provided the
required information or when the parties have agreed that the applicant may
provide additional information later and the interconnection request is ready
to be studied.
c) After
an interconnection request is deemed complete, the EDC shall assign a queue
position to it based upon the date the interconnection request is determined to
be complete. When assigning a queue position, an EDC may consider whether
there are any other interconnection projects on the same distribution circuit.
If there are other interconnection projects on the same distribution circuit,
the EDC may consider them together. If an EDC assigns a queue position based
on the existence of interconnection projects on the same distribution circuit,
the EDC shall notify the applicant of that fact when it assigns the queue position.
The queue position of an interconnection request is used to determine the cost
responsibility for the facilities necessary to accommodate the interconnection.
The EDC shall notify the applicant as to its position in the queue. If the
interconnection request is subsequently amended due to a material modification,
queue position is determined under Section 466.125 Material Modifications.
d) After
the interconnection request has been assigned to the queue, the following
procedures shall be followed in performing a Level 4 study review:
1) By
mutual agreement of the parties, the scoping meeting, interconnection
feasibility study, interconnection impact study, or interconnection facilities
study provided for in a Level 4 review and discussed in this Section may be
waived or combined. The applicant may unilaterally combine the interconnection
feasibility study and the interconnection system impact study. Notwithstanding
the waiver of any studies, any such waiver does not preclude further analysis
and study by the EDC. The applicant retains the obligation to pay all resultant
costs of required upgrades.
2) If
agreed to by the parties, a scoping meeting on a mutually agreed upon date and
time shall be held, after the EDC has notified the applicant that the Level 4
interconnection request is deemed complete, or the applicant has requested that
its interconnection request proceed under Level 4 review after failing the
requirements of a Level 2 or Level 3 review. The meeting's purpose is to
review the interconnection request, existing studies relevant to the
interconnection request, and the results of the Level 2 or Level 3 screening
criteria.
3) When
the parties agree that an interconnection feasibility study shall be performed,
the EDC shall provide to the applicant, no later than 10 business days after
the receipt of a complete interconnection request or, if held, the scoping
meeting, an interconnection feasibility study agreement (see Appendix E),
including an outline of the scope of the study and a non-binding estimate of
the cost to perform the study. If the applicant does not sign and return the
study agreement within 15 business days, the application shall be deemed
withdrawn.
4) When
the parties agree that an interconnection feasibility study is not required,
the EDC shall provide to the applicant, no later than 10 business days after
the receipt of a complete interconnection request or, if held, the scoping
meeting, an interconnection system impact study agreement (see Appendix F),
including an outline of the scope of the study and a non-binding estimate of
the cost to perform the study. If the applicant does not sign and return the
study agreement within 15 business days, the application shall be deemed
withdrawn.
5) If
the parties agree that neither an interconnection feasibility study nor a
system impact study is required, the EDC shall provide to the applicant, no
later than 10 business days after receipt of a complete interconnection request
or, if held, the scoping meeting, an interconnection facilities study agreement
(see Appendix G) including an outline of the scope of the study and an estimate
of the cost to perform the study. If the applicant does not sign and return
the study agreement within 15 business days, the application shall be deemed
withdrawn.
6) Contingent
upgrades that are identified during the evaluation of the interconnection request
shall be documented in the applicable study reports and the interconnection
agreement. For each contingent upgrade, when available, the EDC shall provide non-binding
estimated interconnection facilities and distribution upgrades costs (if any)
and estimated construction schedule upon request of the applicant.
e) The following guidelines
shall govern all required interconnection studies:
1) Unless
waived by an applicant, an interconnection feasibility study shall include any
necessary analyses for identifying a potential adverse system impact to the EDC's
electric distribution system that would result from the interconnection at the
applicant's proposed point of interconnection from among the following:
A) Initial
identification of any circuit breaker short circuit capability limits exceeded because
of the interconnection.
B) Initial
identification of any thermal overload or voltage limit violations resulting
from the interconnection.
C) Initial
review of grounding requirements, including review per IEEE C62.92.6 for
inverter-based DER when additional grounding equipment is considered, and
system protection.
D) Description
and non-binding estimated cost and, if available, construction schedule of
facilities required to interconnect the DER facility to the EDC's electric
distribution system in a safe and reliable manner, including identification of
potential increased expenses due to location, distribution system assets, or
other relevant factors. Cost estimates provided in each instance must be
itemized in line item format and must break down costs by equipment, labor, and
other cost categories. The cost estimates must also provide the component parts
for direct, indirect, and other identified cost categories.
E) If an
applicant requests that the interconnection feasibility study evaluate multiple
potential points of interconnection, additional evaluations may be required. Additional
evaluations shall be paid for by the applicant.
F) An
interconnection system impact study is not required when the interconnection
feasibility study concludes that there is no adverse system impact, or when the
study identifies an adverse system impact, but the EDC is able to identify a
remedy without the need for an interconnection system impact study.
G) A study results meeting will be held within 10 business
days after study completion if requested by the applicant. The study results
meeting will be attended by technical representatives of the EDC and the
applicant. The study results meeting shall not relieve the applicant from its
obligations, nor does it toll the clock for the applicant, to take the actions
required by the rules at that point in the Level 4 review.
H) Each
party may require that the standard form of interconnection feasibility study
agreement approved by the Commission be used. If both parties agree, however,
an alternative form can be used.
2) An
interconnection system impact study evaluates the impact of the proposed
interconnection on both the safety and reliability of the EDC's electric
distribution system. The study identifies and details the system impacts that
interconnecting the DER facility to the distribution system has if there are no
system modifications. It focuses on the potential or actual adverse system
impacts identified in the interconnection feasibility study, including those
that were identified in the scoping meeting. The study shall consider all
other DER facilities that, on the date the interconnection system impact study
is commenced, are directly interconnected with the EDC's system, have a pending
higher queue position to interconnect to the electric distribution system, or
have signed an interconnection agreement.
A) A
distribution interconnection system impact study shall be performed when a
potential distribution system adverse system impact is identified in the
interconnection feasibility study. The EDC shall send the applicant an
interconnection system impact study agreement within 10 business days after
transmittal of the interconnection feasibility study report. The agreement
shall include an outline of the scope of the study and a non-binding estimate
of the cost to perform the study. The system impact study shall take into
account the proposed DER facility's design and operating characteristics and
study the project according to how the project is proposed to be operated. The
applicant must provide adequate design assurance in accordance with Section 466.75,
through demonstration of devices tested to national standards, or approved by
the EDC. The export capacity shall be used except when assessing fault current
contribution, in which case the nameplate rating is appropriate (unless
assurance, approved by the EDC, has been provided showing fault currents are
not directly related to nameplate rating and are controlled by some means). The
impact study shall include any pertinent elements, assumptions, and thresholds
identified in the Impact Study Template in Appendix F.
B) The
final interconnection system impact study shall provide the following:
i) The
underlying assumptions of the study;
ii) A
summary of the analyses;
iii) The
results of the analyses, including detailed information on any impacts
identified, the drivers and reasons for those impacts, including load, voltage,
thermal and other limitations, as well as the boundaries of the impacts, to the
extent possible;
iv) A
list of any potential impediments to providing the requested interconnection
service and information regarding technical thresholds that drive modifications;
v) Required
distribution upgrades;
vi) A
non-binding estimate of cost and time to construct any required distribution
upgrades. Those cost estimates shall provide the component parts for direct,
indirect, and other identified cost categories. Cost estimates must be
itemized and must break down costs by equipment, labor, overhead and other cost
categories; and
vii) If
the cost estimate exceeds 150% of the estimated cost set forth in the
feasibility study, a written itemization, by equipment, labor, overhead and
other cost categories, of the component parts that increased in cost and a
detailed explanation for the cost increase.
C) A
study results meeting will be held within 10 business days after study
completion if requested by the applicant. The study results meeting shall not
relieve the applicant from its obligations, nor does it toll the clock for the
applicant, to take the actions required by the Rules at that point in the Level
4 review.
D) The
parties may use an interconnection impact study agreement as approved by the
Commission. If both parties agree, however, an alternative form can be used.
3) Unless
waived by the applicant, the interconnection facilities study shall be
conducted as follows:
A) The interconnection
facilities study agreement, which includes an outline of the scope of the study
and a non-binding estimate of the cost to perform the study, shall be
transmitted to the applicant within the later of 10 business days after
completion of the interconnection system impact study or 5 business days after
the study results meeting, if performed, or within 10 business days after the
applicant notifies the EDC pursuant to Section 466.90(b)(4)(C), Section
466.100(c)(3), or Section 466.110(b)(3).
B) The
interconnection facilities study shall estimate the cost of the equipment,
engineering, procurement and construction work, including overheads, needed to
implement the conclusions of the interconnection feasibility study and the
interconnection system impact study.
i) Non-binding
cost estimates must be itemized and must break down costs by equipment, labor,
overhead, and other cost categories. These cost estimates must also provide the
component parts for direct, indirect, and other identified cost categories; and
ii) If
the cost estimate exceeds the lesser of 150% of the estimated cost set forth in
the feasibility study or 125% of the estimated cost set forth in the system
impact study, a written itemization, by equipment, labor, overhead and other
cost categories, of the component parts that increased in cost and a detailed
explanation for the cost increase.
C) The
interconnection facilities study shall identify:
i) The
electrical switching configuration of the equipment, including transformer,
switchgear, meters and other station equipment;
ii) The
nature and estimated cost of all the EDC's interconnection facilities and
distribution upgrades necessary to accomplish the interconnection; and
iii) An
estimate for the time required to complete the construction and installation of
the facilities.
D) The
EDC may agree to permit an applicant to separately arrange for a qualified third
party to design and construct the required interconnection facilities. In such
a case:
i) The
applicant shall utilize EDC-approved engineering and construction contractors
for the design and construction of the interconnection facilities, which shall
be built in accordance with the EDC’s specifications;
ii) Such
facilities shall be limited to interconnection facilities serving only the
applicant’s DER facility;
iii) The
applicant shall not include work on existing energized EDC electric
distribution facilities, or in energized EDC substations;
iv) The
applicant must comply with security and confidentiality requirements before the
EDC provides all relevant information and required specifications to the
applicant to permit the applicant to obtain an independent design and cost
estimate for the facilities; and
v) The
EDC shall maintain the right to inspect, test, or witness test all facilities
designed and constructed under the provisions of this subsection and shall be
allowed to recover the associate costs it incurs from the applicant.
E) A
study results meeting will be held within 10 business days after study completion
unless parties mutually agree to waive the meeting. The study results meeting
shall not relieve the applicant from its obligations, nor does it toll the
clock for the applicant, to take the actions required by the rules at point in
the Level 4 review.
F) Upon
completion of the interconnection facilities study, and after the applicant
agrees to pay for the interconnection facilities and distribution upgrades
identified in the interconnection facilities study, the EDC shall provide a
standard DER interconnection agreement (see Appendix D) for the applicant to
sign the day the EDC makes its determination.
G) In the
event that distribution upgrades due to the impact of the interconnection
request are identified in the impact study that shall be added only in the
event that higher-queued customers not yet interconnected eventually complete
and interconnect their generation facilities, the applicant may elect to
interconnect without paying for such upgrades at the time of the
interconnection, provided that it agrees to pay for such upgrades at the time
the higher-queued customer is ready to interconnect. If the applicant does not
pay for such upgrades at that time, the EDC shall require the applicant to
immediately disconnect its distribution generation facility to accommodate the
higher-queued customer.
H) Notwithstanding
anything to the contrary, nothing prohibits two or more joint applicants
directly adjacent in the interconnection queue on a feeder or substation from
jointly informing the EDC of a request for a group study or estimate. That
notice shall be provided on a form approved by the Commission that, at minimum,
authorizes a group study with costs for upgrades and the facilities study to be
shared as determined by the joint applicants and waives confidentiality
protections only to the extent necessary to generate and circulate that group study.
For the purposes of this subsection, a "group study" is an impact
study or facilities study created and issued under subsection (e)(2) or (e)(3)
(as applicable) that studies the least-cost upgrades to interconnect all of the
joint applicants' facilities.
I) The
parties shall use an interconnection facilities study agreement approved by the
Commission. If both parties agree, however, an alternative form can be used.
4) All
studies analyzing or projecting load flow or system impact shall take into
account the impact of storage, operating profile (including voluntary
operational restrictions), impact and timing of load flow, or other parameters
provided by the applicant that would impact timing or volume of load flow. Any
parameters shall be reflected in Attachment 2 to the interconnection agreement.
When performing feasibility studies, system impact studies, and facility
studies for a DER facility, operating characteristics (including maximum export
and import capacity) as identified in the application by the applicant shall be
utilized, except that fault current contribution shall be evaluated based on
aggregate AC nameplate rating. The utility's technical review shall determine
whether the proposed facility, operating per the characteristics identified in
the application and with any necessary controls, can be safely and reliably
interconnected to the utility's distribution system.
f) When
an EDC determines because of the studies conducted under a Level 4 review that
it is appropriate to interconnect the DER facility, the EDC shall provide the
applicant with a standard DER interconnection agreement. If the
interconnection request is denied, the EDC shall provide the applicant with a
written explanation as to its reasons for denying interconnection. If denied,
the interconnection request does not retain its position in the queue.
g) Within
30 business days after receipt of the standard DER interconnection agreement,
the applicant shall provide all necessary information required of the applicant
by the agreement, and the EDC shall develop all other information required of
the EDC by the agreement. After completing the agreement with the additional
information, the applicant shall sign and return the agreement to the EDC. If
the applicant does not sign and return the agreement within 30 business days
after its completion, the interconnection request shall be deemed withdrawn,
unless the applicant requests in writing to have the deadline extended by no more
than 15 business days. The EDC shall not deny an initial request for
extension. If the applicant does not sign the agreement after the 15-business-day
extension, the interconnection request shall be deemed withdrawn. The EDC
shall return a fully executed DER interconnection agreement within 10 business
days of receipt of the signed agreement from the applicant. If withdrawn, the
interconnection request does not retain its position in the queue. When
construction is required, the interconnection of the DER facility shall proceed
according to milestones agreed to by the parties in the standard DER
interconnection agreement.
h) The DER
facility is not permitted to operate until:
1) The
requirements of the interconnection agreement are satisfied;
2) The DER
facility is approved by electric code officials with jurisdiction over the
interconnection;
3) The
applicant provides a certificate of completion (see Appendix B) to the EDC. Completion
of local inspections may be designated on inspection forms used by local
inspecting authorities; and
4) The

ADMINISTRATIVE CODE TITLE 83: PUBLIC UTILITIES CHAPTER I: ILLINOIS COMMERCE COMMISSION SUBCHAPTER c: ELECTRIC UTILITIES PART 466 ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES SECTION 466.125 MATERIAL MODIFICATIONS
Section
466.125 Material Modifications
a) At any time
after an application is deemed complete, including during the pendency of tasks
identified in Sections 466.90, 466.100, 466.110, or 466.120, the applicant or
the EDC may identify modifications to the proposed DER facility. An existing
interconnected DER facility may also propose modifications. The applicant shall
submit to the EDC, in writing, all proposed modifications to any information
provided in the interconnection request or interconnection agreement for
existing DER facilities. Neither the applicant nor the EDC may unilaterally
modify the application or interconnection agreement.
b) Within 10
business days after receipt of a proposed modification, the EDC shall notify
the applicant whether a proposed modification to either an application or an
existing DER facility constitutes a material modification.
c) Material Modification
Process for Proposed DER
1) For proposed
generating facilities with an active interconnection request, a material
modification shall include, but is not limited to, a modification of the interconnection
request that:
A) changes the
physical location of the point of interconnection such that it is likely to affect
the scope of upgrades required to interconnect the DER;
B) increases the
export capacity or extends the operating profile of the DER facility;
C) adds or
removes energy storage or changes the energy storage operating characteristic;
D) changes or
replaces generating equipment (e.g., generators, inverters, transformers,
relaying, controls) and substitutes with equipment that is not a like-kind
modification;
E) changes
transformer connections or grounding; or
F) changes to a
certified inverter with different specifications or different inverter control
settings or configuration.
2) If the proposed
modification is determined to be a material modification, then the EDC shall
notify the applicant in writing that the applicant may elect to either:
A) withdraw the proposed
modification; or
B) withdraw the
interconnection request and proceed with a new interconnection request for the
modification.
3) The
applicant shall provide its election in writing to the EDC within 10 business
days after being provided the material modification determination results. If
the applicant does not provide its election, the proposed modification shall be
deemed withdrawn and the queue position of the withdrawn application will be
forfeited. If the applicant and EDC do not agree, either party may initiate
dispute resolution pursuant to Section 466.130.
d) A modification
that is not determined to be material may still require evaluation and
acceptance by the EDC. The applicant is obligated to pay any necessary study
costs of the evaluation. The EDC will notify the applicant of any additional
fees or information that may be required to recommence the interconnection
review process and restudy the application in order to evaluate the
modification. The applicant shall have 10 business days to provide any
requested information or required fees. The evaluation will be performed within
15 business days after the EDC receives the required fees or information from
the applicant. If the proposed modification is determined not to be a material
modification, then the EDC shall conduct the technical review within the
remaining time allotted by subsection (b) and an additional 10 business days if
needed by the EDC. The EDC shall notify the applicant in writing that the
modification has been accepted, and that the applicant shall retain its
eligibility for interconnection and maintain its position in the
interconnection queue. A modification that is not determined to be material
does not require a new interconnection request.
e) Material Modification
Process for Existing Interconnected DER
1) For existing
interconnected DER facilities with an active interconnection request and have
received a certificate of completion, a material modification shall include,
but is not limited to, a modification of the interconnection request that:
A) changes the physical
location of the point of interconnection in a manner likely to have an impact
on technical review;
B) changes the
net power flow injection to the feeder, changes the nameplate capacity, or
changes the operating characteristics of the DER facility;
C) adds or
removes energy storage or changes the energy storage operating characteristics;
D) changes or
replaces generating equipment (e.g., generators, inverters, transformers,
relaying, controls), and substitutes equipment that is not a like-kind modification;
E) changes
transformer connections or grounding; and/or
F) changes to a
certified inverter with different specifications or different inverter control
settings or configuration.
2) The EDC
shall notify the applicant in writing that the applicant may elect to either:
A) withdraw the proposed
modification; or
B) submit a new interconnection request
for modification.
3) The
applicant shall provide its election in writing to the EDC within 10 business
days after being provided the material modification determination results. If
the applicant does not provide its election, the proposed modification shall be
deemed withdrawn and the modification to the existing interconnected DER
facility shall not be allowed. If the applicant and EDC do not agree, either
party may initiate dispute resolution pursuant to Section 466.130.
4) A
modification that is not determined to be material may still require evaluation
and acceptance by the EDC, which includes but is not limited to witness testing
and setting verifications. The interconnection customer is obligated to pay any
applicable fees associated with the EDC’s evaluation of the proposed
modification. The EDC will notify the interconnection customer of any
additional fees and/or information that may be required to evaluate the
proposed modification within five business days of providing the material
modification determination results. The interconnection customer shall have 10
business days to provide any requested information and/or required fees. If the
proposed modification is determined not to be a material modification, then the
EDC shall notify the interconnection customer in writing within 10 business
days that the modification has been accepted, contingent upon witness testing,
where applicable.

PART 466
ELECTRIC INTERCONNECTION OF DISTRIBUTED ENERGY RESOURCES FACILITIES
SECTION 466.130 DISPUTES
Section 466.130 Disputes
a) It is the policy of the Commission that applicants for
interconnection and EDCs should, to the maximum extent possible, endeavor to
resolve interconnection disputes through negotiation and without resorting to
the processes of the Commission. A party shall attempt to resolve all
disputes regarding interconnection promptly and in a good faith manner. A party
shall provide prompt written notice of the existence of the dispute, including
sufficient detail to identify the scope of the dispute, to the other party in
order to attempt to resolve the dispute in a good faith manner.
b) An
informal meeting between the parties shall be held within 10 business days
after receipt of the written notice. Persons with decision-making authority
from each party shall attend such meeting. In the event said dispute involves
technical issues, persons with sufficient technical expertise and familiarity
with the issue in dispute from each Party shall also attend the informal meeting.
If the parties agree, such a meeting may be conducted by teleconference. The
informal process between the parties shall extend 30 days after the receipt of
written notice, after which the dispute is deemed resolved and the timeframes
for decisions within the interconnection process resume, unless one of the
parties seeks resolution through non-binding arbitration procedures described
in subsection (c) or files a formal complaint at the Commission prior to the
end of the 30-day period. If the negotiations do not resolve the dispute
within 10 business days after commencing, either party may proceed to subsection
(c) upon providing written notice to the other party.
c) Ombudsman
1) If
the parties are unable to resolve the dispute through an informal meeting or
meetings, either party may submit the interconnection dispute to an Ombudsman
for non-binding arbitration. The party electing arbitration shall notify the
other party of the request in writing.
2) For
purposes of this Section, the Ombudsman, as that term in used in Section
16-107.5(h-5)(2) of the Act for that dispute may be:
A) the
American Arbitration Association (AAA) or an individual arbitrator or team of
arbitrators selected by the parties pursuant to AAA rules;
B) Commission
employees designated on the Commission's website, as available; or
C) a
third party selected by the parties.
3) In
designating one or more of its employees as a potential Ombudsman for a
dispute, the Commission may identify an hourly fee for that individual's time
spent on arbitration; the Commission shall invoice and collect a fee equal to
the hourly rate multiplied by hours spent on the arbitration in equal shares
from the parties to the arbitration.
4) Each
party shall bear its own fees, costs, and expenses and an equal share of the
expenses of the non-binding arbitration.
5) The
non-binding arbitration process is limited to 60 days unless the parties and
the Ombudsman agree to a longer period.
d) Within
10 days after the conclusion of the procedures in subsection (c), either party
may initiate a formal complaint with the Commission and ask for an expedited
resolution of the dispute. If the complaint seeks expedited resolution, any
written recommendation of the Ombudsman shall be appended to the complaint. If
a party fails to file a formal complaint within this 10-day timeframe, it
waives its right to obtain relief from the Commission and the dispute is deemed
resolved.
e) Pursuit
of dispute resolution shall not affect an interconnection applicant with regard
to consideration of an interconnection request or an interconnection
applicant's position in the EDC's interconnection queue of any pending
application or interconnection agreement.

(EDC)), a
|
|
existing under the laws of the State of
|
|
Illinois. Interconnection customer and EDC each may be
referred to as a "Party," or collectively as the "Parties."
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Recitals:
Whereas, interconnection customer is proposing to
install or direct the installation of a distributed energy resources (DER)
facility, or is proposing a generating capacity addition to an existing DER
facility, consistent with the interconnection request application form
completed by interconnection customer on ________________; and
Whereas, the interconnection customer will operate
and maintain, or cause the operation and maintenance of, the DER facility; and
Whereas, interconnection customer desires to
interconnect the DER facility with EDC's electric distribution system.
Now, therefore, in consideration of the premises and
mutual covenants set forth in this Agreement, and other good and valuable consideration,
the receipt, sufficiency and adequacy of which are hereby acknowledged, the
Parties covenant and agree as follows:
Article 1. Scope and Limitations of Agreement
1.1 This
Agreement shall be used for all approved interconnection requests for DER
facilities that fall under Levels 1, 2, 3 and 4 according to the procedures set
forth in Part 466 of the Commission's rules (83 Ill. Adm. Code 466) (referred
to as the Illinois Distributed Energy Resources Interconnection Standard).
1.2 This
Agreement governs the terms and conditions under which the DER facility will
interconnect to, and operate in parallel with, the EDC's electric distribution
system.
1.3 This
Agreement does not constitute an agreement to purchase or deliver the
interconnection customer's power.
1.4 Nothing
in this Agreement is intended to affect any other agreement between the EDC and
the interconnection customer.
1.5 Terms
used in this Agreement are defined as in Section 466.20 of the Illinois
Distributed Energy Resources Interconnection Standard unless otherwise noted.
1.6 Responsibilities of the Parties
1.6.1 The
Parties shall perform all obligations of this Agreement in accordance with all
applicable laws and regulations.
1.6.2 The EDC
shall construct, own, operate, and maintain its interconnection facilities in
accordance with this Agreement.
1.6.3 The
interconnection customer shall construct, own, operate, and maintain its DER
facility and interconnection facilities in accordance with this Agreement.
1.6.4 Each
Party shall operate, maintain, repair, and inspect, and shall be fully
responsible for, the facilities that it now or subsequently may own unless
otherwise specified in the attachments to this Agreement. Each Party shall be
responsible for the safe installation, maintenance, repair and condition of its
respective lines and appurtenances on its respective sides of the point of
interconnection.
1.6.5 The
interconnection customer agrees to design, install, maintain and operate its DER
facility so as to minimize the likelihood of causing an adverse system impact
on the electric distribution system or any other electric system that is not
owned or operated by the EDC.
1.7 Parallel Operation Obligations
Once the DER facility has been
authorized to commence parallel operation, the interconnection customer shall
abide by all operating procedures established in IEEE Standard 1547 and any
other applicable laws, statutes or guidelines, including those specified in
Attachment 4 of this Agreement.
1.8 Metering
The interconnection customer shall
be responsible for the cost to purchase, install, operate, maintain, test,
repair, and replace metering and data acquisition equipment specified in
Attachments 5 and 6 of this Agreement.
1.9 Reactive Power
1.9.1 Interconnection
customers with a DER facility larger than or equal to 1 MVA shall design their DER
facilities to maintain a power factor at the point of interconnection between
.95 lagging and .95 leading at all times. Interconnection customers with a DER
facility smaller than 1 MVA shall design their DER facility to maintain a power
factor at the point of interconnection between .90 lagging and .90 leading at all
times.
1.9.2 Any EDC
requirements for meeting a specific voltage or specific reactive power schedule
as a condition for interconnection shall be clearly specified in Attachment 4.
Under no circumstance shall the EDC's additional requirements for voltage or
reactive power schedules exceed the normal operating capabilities of the DER
facility.
1.9.3 If the
interconnection customer does not operate the DER facility within the power
factor range specified in Attachment 4, or does not operate the distribute
generation facility in accordance with a voltage or reactive power schedule
specified in Attachment 4, the interconnection customer is in default under this
Agreement, and the terms of Article 6.5 apply.
1.10 Standards of Operations
The interconnection customer must
obtain all certifications, permits, licenses and approvals necessary to
construct, operate and maintain the facility and to perform its obligations
under this Agreement. The interconnection customer is responsible for
coordinating and synchronizing the DER facility with the EDC's system. The
interconnection customer is responsible for any damage that is caused by the
interconnection customer's failure to coordinate or synchronize the DER
facility with the electric distribution system. The interconnection customer
agrees to be primarily liable for any damages resulting from the continued
operation of the DER facility after the EDC ceases to energize the line section
to which the DER facility is connected. In Attachment 4, the EDC shall specify
the shortest reclose time setting for its protection equipment that could
affect the DER facility. The EDC shall notify the interconnection customer at
least 10 business days prior to adopting a faster reclose time on any automatic
protective equipment, such as a circuit breaker or line recloser, that might
affect the DER facility.
Article 2. Inspection, Testing, Authorization,
and Right of Access
2.1 Equipment Testing and Inspection
The interconnection customer shall
test and inspect its DER facility including the interconnection equipment prior
to interconnection in accordance with IEEE Standard 1547 (2003) and IEEE
Standard 1547.1 (2005). The interconnection customer shall not operate its DER
facility in parallel with the EDC's electric distribution system without prior
written authorization by the EDC as provided for in Articles 2.1.1-2.1.3.
2.1.1 The EDC
shall perform a witness test after construction of the DER facility is
completed, but before parallel operation, unless the EDC specifically waives
the witness test. The interconnection customer shall provide the EDC at least
15 business days' notice of the planned commissioning test for the DER
facility. If the EDC performs a witness test at a time that is not concurrent
with the commissioning test, it shall contact the interconnection customer to
schedule the witness test at a mutually agreeable time within 10 business days
after the scheduled commissioning test designated on the application. If the
EDC does not perform the witness test within 10 business days after the
commissioning test, the witness test is deemed waived unless the Parties mutually
agree to extend the date for scheduling the witness test, or unless the EDC
cannot do so for good cause, in which case, the Parties shall agree to another
date for scheduling the test within 10 business days after the original
scheduled date. If the witness test is not acceptable to the EDC, the EDC shall
deliver in writing a detailed technical description of all deficiencies of the DER
facility identified by the EDC during the witness test. The interconnection
customer has 30 business days after receipt of the written description to
address and resolve any deficiencies. This time period may be extended upon
agreement between the EDC and the interconnection customer. If the
interconnection customer fails to address and resolve the deficiencies to the
satisfaction of the EDC, the applicable cure provisions of Article 6.5 shall
apply. The interconnection customer shall, if requested by the EDC, provide a
copy of all documentation in its possession regarding testing conducted
pursuant to IEEE Standard 1547.1.
2.1.2 If the
interconnection customer conducts interim testing of the DER facility prior to
the witness test, the interconnection customer shall obtain permission from the
EDC before each occurrence of operating the DER facility in parallel with the
electric distribution system. The EDC may, at its own expense, send qualified
personnel to the DER facility to observe such interim testing, but it cannot
mandate that these tests be considered in the final witness test. The EDC is
not required to observe the interim testing or precluded from requiring the
tests be repeated at the final witness test. During and leading up to the
witness test, the EDC shall not limit the interconnection customer's ability to
test the DER facility during normal working hours except for safety and
reliability reasons.
2.1.3 After
the DER facility passes the witness test, the EDC shall affix an authorized
signature to the certificate of completion and return it to the interconnection
customer approving the interconnection and authorizing parallel operation. The
authorization shall not be conditioned or delayed and the EDC shall return the
signed certificate of completion to the interconnection customer no more than
10 business days after the date that the DER facility passes the witness test.
2.2 Commercial Operation
The interconnection customer shall
not operate the DER facility, except for interim testing as provided in Article
2.1, until such time as the certificate of completion is signed by all Parties.
2.3 Right of Access
The EDC must have access to the
disconnect switch and metering equipment of the DER facility at all times. When
practical, the EDC shall provide notice to the customer prior to using its
right of access.
Article 3. Effective Date, Term, Termination, and
Disconnection
3.1 Effective Date
This Agreement shall become
effective upon execution by all Parties.
3.2 Term of Agreement
This Agreement shall become
effective on the effective date and shall remain in effect unless terminated in
accordance with Article 3.3 of this Agreement.
3.3 Termination
3.3.1 The
interconnection customer may terminate this Agreement at any time by giving the
EDC 30 calendar days prior written notice.
3.3.2 Either Party may terminate
this Agreement after default pursuant to Article 6.5.
3.3.3 The EDC
may terminate, upon 60 calendar days' prior written notice, for failure of the
interconnection customer to complete construction of the DER facility within 12
months after the in-service date as specified by the Parties in Attachment 2,
which may be extended by agreement between the Parties.
3.3.4 The EDC
may terminate this Agreement, upon 60 calendar days' prior written notice, if
the interconnection customer has abandoned, cancelled, permanently disconnected
or stopped development, construction, or operation of the DER facility, or if
the interconnection customer fails to operate the DER facility in parallel with
the EDC's electric system for three consecutive years.
3.3.5 Upon
termination of this Agreement, the DER facility will be disconnected from the
EDC's electric distribution system. Terminating this Agreement does not relieve
either Party of its liabilities and obligations that are owed or continuing
when the Agreement is terminated.
3.3.6 If the
Agreement is terminated, the interconnection customer loses its position in the
interconnection queue.
3.4 Temporary Disconnection
A Party may temporarily disconnect
the DER facility from the electric distribution system in the event one or more
of the following conditions or events occurs:
3.4.1 Emergency
conditions – shall mean any condition or situation: (1) that in the judgment of
the Party making the claim is likely to endanger life or property; or (2) that
the EDC determines is likely to cause an adverse system impact, or is likely to
have a material adverse effect on the EDC's electric distribution system,
interconnection facilities or other facilities, or is likely to interrupt or
materially interfere with the provision of electric utility service to other
customers; or (3) that is likely to cause a material adverse effect on the DER
facility or the interconnection equipment. Under emergency conditions, the EDC
or the interconnection customer may suspend interconnection service and
temporarily disconnect the DER facility from the electric distribution system.
The EDC must notify the interconnection customer when it becomes aware of any
conditions that might affect the interconnection customer's operation of the DER
facility. The interconnection customer shall notify the EDC when it becomes
aware of any condition that might affect the EDC's electric distribution
system. To the extent information is known, the notification shall describe the
condition, the extent of the damage or deficiency, the expected effect on the
operation of both Parties' facilities and operations, its anticipated duration,
and the necessary corrective action.
3.4.2 Scheduled
maintenance, construction, or repair – the EDC may interrupt interconnection
service or curtail the output of the DER facility and temporarily disconnect
the DER facility from the EDC's electric distribution system when necessary
for scheduled maintenance, construction, or repairs on EDC's electric
distribution system. The EDC shall provide the interconnection customer with
notice no less than 5 business days before an interruption due to scheduled
maintenance, construction, or repair, or the EDC shall provide notice
immediately if the scheduled maintenance, construction, or repair is scheduled
less than 5 business days in advance. The EDC shall coordinate the reduction
or temporary disconnection with the interconnection customer; however, the
interconnection customer is responsible for out-of-pocket costs incurred by the
EDC for deferring or rescheduling maintenance, construction or repair at the
interconnection customer's request.
3.4.3 Forced
outages – The EDC may suspend interconnection service to repair the EDC's
electric distribution system. The EDC shall provide the interconnection
customer with prior notice, if possible. If prior notice is not possible, the
EDC shall, upon written request, provide the interconnection customer with
written documentation, after the fact, explaining the circumstances of the
disconnection.
3.4.4 Adverse
system impact – the EDC must provide the interconnection customer with written
notice of its intention to disconnect the DER facility, if the EDC determines
that operation of the DER facility creates an adverse system impact. The
documentation that supports the EDC's decision to disconnect must be provided
to the interconnection customer. The EDC may disconnect the DER facility if,
after receipt of the notice, the interconnection customer fails to remedy the
adverse system impact, unless emergency conditions exist, in which case, the
provisions of Article 3.4.1 apply. The EDC may continue to leave the generating
facility disconnected until the adverse system impact is corrected.
3.4.5 Modification
of the DER facility – The interconnection customer must receive written
authorization from the EDC prior to making any change to the DER facility,
other than a minor equipment modification. If the interconnection customer
modifies its facility without the EDC's prior written authorization, the EDC
has the right to disconnect the DER facility until such time as the EDC
concludes the modification poses no threat to the safety or reliability of its
electric distribution system.
3.4.6 The
EDC's compliance with Article 3 shall preclude any claim for damages for any
lost opportunity or other costs incurred by the interconnection customer as a
result of an interruption of service under Article 3. Any dispute over whether
the EDC complied with Article 3 shall be resolved in accordance with the
dispute resolution mechanism set forth in Article 8.
Article 4. Cost Responsibility for
Interconnection Facilities and Distribution Upgrades
4.1 Interconnection Facilities
4.1.1 The
interconnection customer shall pay, or reimburse the EDC, as applicable, for
the cost of the interconnection facilities itemized in Attachment 3. The EDC
shall identify the additional interconnection facilities necessary to
interconnect the DER facility with the EDC's electric distribution system, the
cost of those facilities, and the time required to build and install those
facilities, as well as an estimated date of completion of the building or
installation of those facilities.
4.1.2 The
interconnection customer is responsible for its expenses, including overheads,
associated with owning, operating, maintaining, repairing, and replacing its
interconnection equipment.
4.2 Distribution Upgrades
The EDC shall design, procure,
construct, install, and own any distribution upgrades. The actual cost of the
distribution upgrades, including overheads, shall be directly assigned to the
interconnection customer whose DER facility caused the need for the distribution
upgrades.
Article 5. Billing, Payment, Milestones, and
Financial Security
5.1 Billing
and Payment Procedures and Final Accounting (Applies to supplemental reviews
conducted under Level 1, 2 or 3 review with EDC construction necessary for
accommodating the DER facility, and Level 4 reviews)
5.1.1 The EDC
shall bill the interconnection customer for the design, engineering,
construction, and procurement costs of EDC-provided interconnection facilities
and distribution upgrades contemplated by this Agreement as set forth in
Attachment 3. The billing shall occur on a monthly basis, or as otherwise
agreed to between the Parties. The interconnection customer shall pay each bill
within 30 calendar days after receipt, or as otherwise agreed to between the
Parties.
5.1.2 Unless
waived by the interconnection customer, within 90 calendar days after
completing the construction and installation of the EDC's interconnection
facilities and distribution upgrades described in Attachments 2 and 3 to this
Agreement, the EDC shall provide the interconnection customer with a final
accounting report of any difference between (1) the actual cost incurred to
complete the construction and installation of the EDC's interconnection
facilities and distribution upgrades; and (2) the interconnection customer's
previous deposit and aggregate payments to the EDC for the interconnection
facilities and distribution upgrades. If the interconnection customer's cost
responsibility exceeds its previous deposit and aggregate payments, the EDC
shall invoice the interconnection customer for the amount due and the
interconnection customer shall pay the EDC within 30 calendar days. If the
interconnection customer's previous deposit and aggregate payments exceed its
cost responsibility under this Agreement, the EDC shall refund to the
interconnection customer an amount equal to the difference within 30 calendar
days after the final accounting report. Upon request from the interconnection
customer, if the difference between the budget estimate and the actual cost
exceeds 20%, the EDC will provide a written explanation for the difference.
5.1.3 If a
Party disputes any portion of its payment obligation pursuant to this Article
5, the Party shall pay in a timely manner all non-disputed portions of its
invoice, and the disputed amount shall be resolved pursuant to the dispute
resolution provisions contained in Article 8. A Party disputing a portion of an
Article 5 payment shall not be considered to be in default of its obligations under
this Article.
5.2 Interconnection Customer Deposit
Within 15 business days after
signing and returning the interconnection agreement to the EDC, the
interconnection customer shall provide the EDC with a deposit equal to 100% of
the estimated, non-binding cost to procure, install, or construct any such
facilities. However, when the estimated date of completion of the building or
installation of facilities exceeds three months from the date of notification,
pursuant to Article 4.1.1 of this Agreement, this deposit may be held in escrow
by a mutually agreed-upon third-party, with any interest to inure to the
benefit of the interconnection customer. To the extent
that this interconnection agreement is terminated for any reason, the EDC shall
return all deposits provided by the interconnection customer, less any actual
costs incurred by the EDC.
Article 6. Assignment, Limitation on Damages,
Indemnity, Force Majeure, and Default
6.1 Assignment
This Agreement may be assigned by
either Party. If the interconnection customer attempts to assign this Agreement,
the assignee must agree to the terms of this Agreement in writing and such
writing must be provided to the EDC. Any attempted assignment that violates
this Article is void and ineffective. Assignment shall not relieve a Party of
its obligations, nor shall a Party's obligations be enlarged, in whole or in
part, by reason of the assignment. An assignee is responsible for meeting the
same obligations as the assignor.
6.1.1 Either
Party may assign this Agreement without the consent of the other Party to any
affiliate (including mergers, consolidations or transfers, or a sale of a
substantial portion of the Party's assets, between the Party and another
entity), of the assigning Party that has an equal or greater credit rating and
the legal authority and operational ability to satisfy the obligations of the
assigning Party under this Agreement.
6.1.2 The
interconnection customer can assign this Agreement, without the consent of the
EDC, for collateral security purposes to aid in providing financing for the DER
facility.
6.2 Limitation on Damages
Except for cases of gross
negligence or willful misconduct, the liability of any Party to this Agreement
shall be limited to direct actual damages and reasonable attorney's fees, and
all other damages at law are waived. Under no circumstances, except for cases
of gross negligence or willful misconduct, shall any Party or its directors,
officers, employees and agents, or any of them, be liable to another Party,
whether in tort, contract or other basis in law or equity for any special,
indirect, punitive, exemplary or consequential damages, including lost profits,
lost revenues, replacement power, cost of capital or replacement equipment.
This limitation on damages shall not affect any Party's rights to obtain
equitable relief, including specific performance, as otherwise provided in this
Agreement. The provisions of this Article 6.2 shall survive the termination or
expiration of the Agreement.
6.3 Indemnity
6.3.1 This
provision protects each Party from liability incurred to third parties as a
result of carrying out the provisions of this Agreement. Liability under this
provision is exempt from the general limitations on liability found in Article
6.2.
6.3.2 The interconnection
customer shall indemnify and defend the EDC and the EDC's directors, officers,
employees, and agents, from all damages and expenses resulting from a third
party claim arising out of or based upon the interconnection customer's (a)
negligence or willful misconduct or (b) breach of this Agreement.
6.3.3 The EDC
shall indemnify and defend the interconnection customer and the interconnection
customer's directors, officers, employees, and agents from all damages and
expenses resulting from a third party claim arising out of or based upon the
EDC's (a) negligence or willful misconduct or (b) breach of this Agreement.
6.3.4 Within
5 business days after receipt by an indemnified Party of any claim or notice
that an action or administrative or legal proceeding or investigation as to
which the indemnity provided for in this Article may apply has commenced, the
indemnified Party shall notify the indemnifying Party of such fact. The failure
to notify, or a delay in notification, shall not affect a Party's
indemnification obligation unless that failure or delay is materially
prejudicial to the indemnifying Party.
6.3.5 If an
indemnified Party is entitled to indemnification under this Article as a result
of a claim by a third party, and the indemnifying Party fails, after notice and
reasonable opportunity to proceed under this Article, to assume the defense of
such claim, that indemnified Party may, at the expense of the indemnifying
Party, contest, settle or consent to the entry of any judgment with respect to,
or pay in full, the claim.
6.3.6 If an
indemnifying Party is obligated to indemnify and hold any indemnified Party
harmless under this Article, the amount owing to the indemnified person shall
be the amount of the indemnified Party's actual loss, net of any insurance or
other recovery.
6.4 Force Majeure
6.4.1 As used
in this Article, a force majeure event shall mean any act of God, labor
disturbance, act of the public enemy, war, acts of terrorism, insurrection,
riot, fire, storm or flood, explosion, breakage or accident to machinery or
equipment through no direct, indirect, or contributory act of a Party, any
order, regulation or restriction imposed by governmental, military or lawfully
established civilian authorities, or any other cause beyond a Party's control.
A force majeure event does not include an act of gross negligence or
intentional wrongdoing by the Party claiming force majeure.
6.4.2 If a
force majeure event prevents a Party from fulfilling any obligations under this
Agreement, the Party affected by the force majeure event ("Affected Party")
shall notify the other Party of the existence of the force majeure event within
one business day. The notification must specify the circumstances of the force
majeure event, its expected duration, and the steps that the Affected Party is
taking and will take to mitigate the effects of the event on its performance.
If the initial notification is verbal, it must be followed up with a written
notification within one business day. The Affected Party shall keep the other
Party informed on a continuing basis of developments relating to the force
majeure event until the event ends. The Affected Party may suspend or modify
its obligations under this Agreement (other than the obligation to make
payments) only to the extent that the effect of the force majeure event cannot
be otherwise mitigated.
6.5 Default
6.5.1 No
default shall exist when the failure to discharge an obligation (other than the
payment of money) results from a force majeure event as defined in this
Agreement, or the result of an act or omission of the other Party.
6.5.2 A Party
shall be in default ("Default") of this Agreement if it fails in any
material respect to comply with, observe or perform, or defaults in the
performance of, any covenant or obligation under this Agreement and fails to
cure the failure within 60 calendar days after receiving written notice from
the other Party. Upon a default of this Agreement, the non-defaulting Party
shall give written notice of the default to the defaulting Party. Except as
provided in Article 6.5.3, the defaulting Party has 60 calendar days after
receipt of the default notice to cure the default; provided, however, if the
default cannot be cured within 60 calendar days, the defaulting Party shall
commence the cure within 20 calendar days after original notice and complete the
cure within six months from receipt of the default notice; and, if cured within
that time, the default specified in the notice shall cease to exist.
6.5.3 If a
Party has assigned this Agreement in a manner that is not specifically
authorized by Article 6.1, fails to provide reasonable access pursuant to
Article 2.3, and is in default of its obligations pursuant to Article 7, or if
a Party is in default of its payment obligations pursuant to Article 5 of this
Agreement, the defaulting Party has 30 days from receipt of the default notice
to cure the default.
6.5.4 If a
default is not cured as provided for in this Article, or if a default is not
capable of being cured within the period provided for in this Article, the
non-defaulting Party shall have the right to terminate this Agreement by
written notice, and be relieved of any further obligation under this Agreement
and, whether or not that Party terminates this Agreement, to recover from the
defaulting Party all amounts due under this Agreement, plus all other damages
and remedies to which it is entitled at law or in equity. The provisions of
this Article shall survive termination of this Agreement.
Article 7. Insurance
For DER facilities with a nameplate capacity of 1 MVA or
above, the interconnection customer shall carry sufficient insurance coverage so
that the maximum comprehensive/general liability coverage that is continuously
maintained by the interconnection customer during the term shall be not less
than $2,000,000 for each occurrence, and an aggregate, if any, of at least
$4,000,000. The EDC, its officers, employees and agents shall be added as an
additional insured on this policy. The interconnection customer agrees to
provide the EDC with at least 30 calendar days advance written notice of
cancellation, reduction in limits, or non-renewal of any insurance policy
required by this Article.
Article 8. Dispute Resolution
8.1 Parties
shall attempt to resolve all disputes regarding interconnection as provided in
this Article in a good faith manner.
8.2 If
there is a dispute between the Parties about implementation or an
interpretation of the Agreement, the aggrieved Party shall issue a written
notice to the other Party to the Agreement that specifies the dispute and the
Agreement articles that are disputed.
8.3 A
meeting between the Parties shall be held within 10 days after receipt of the
written notice. Persons with decision-making authority from each Party shall
attend the meeting. If the dispute involves technical issues, persons with
sufficient technical expertise and familiarity with the issue in dispute from
each Party shall also attend the meeting. The meeting may be conducted by
teleconference. The informal process between the parties shall extend 30 days
after the receipt of written notice, after which the dispute is deemed resolved
and the timeframes for decisions within the interconnection process resume,
unless one of the parties seeks resolution through non-binding arbitration
procedures described in Article 8.4 or files a formal complaint at the
Commission prior to the end of the 30-day period.
8.4 If the
parties are unable to resolve the dispute through the process outlined in Article
8.3, either party may submit the interconnection dispute to an Ombudsman for non-binding
arbitration. The party electing non-binding arbitration shall notify the other
party of the request in writing. The non-binding arbitration process is limited
to 60 days, absent mutual agreement of the parties and the Ombudsman to a
longer period.
8.5 Each
party shall bear its own fees, costs and expenses and an equal share of the
expenses of the non-binding arbitration.
8.6 Within
10 days after the conclusion of the procedures in Article 8.4, either party may
initiate a formal complaint with the Commission and ask for an expedited
resolution of the dispute. If the complaint seeks expedited resolution, any
written recommendation of the Ombudsman shall be appended to the complaint. The
formal complaint shall proceed as a contested hearing pursuant to the
Commission’s Rules of Practice.
8.7 A party
may, after good faith negotiations have failed, decline to pursue non-binding
arbitration and instead initiate a formal complaint with the Commission. The
formal complaint shall proceed as a contested hearing pursuant to the
Commission's Rules of Practice.
8.8 Pursuit
of dispute resolution may not affect an interconnection request or an
interconnection applicant's position in the EDC's interconnection queue.
8.9 If the
Parties fail to resolve their dispute under the dispute resolution provisions
of this Article, nothing in this Article shall affect any Party's rights to
obtain equitable relief, including specific performance, as otherwise provided
in this Agreement.
Article 9. Miscellaneous
9.1 Governing Law, Regulatory Authority, and Rules
The validity, interpretation and
enforcement of this Agreement and each of its provisions shall be governed by
the laws of the State of Illinois, without regard to its conflicts of law
principles. This Agreement is subject to all applicable laws and regulations.
Each Party expressly reserves the right to seek change in, appeal, or otherwise
contest any laws, orders or regulations of a governmental authority. The
language in all parts of this Agreement shall in all cases be construed as a
whole, according to its fair meaning, and not strictly for or against the EDC
or interconnection customer, regardless of the involvement of either Party in
drafting this Agreement.
9.2 Amendment
Modification of this Agreement
shall be only by a written instrument duly executed by both Parties.
9.3 No Third-Party Beneficiaries
This Agreement is not intended to
and does not create rights, remedies, or benefits of any character whatsoever
in favor of any persons, corporations, associations, or entities other than the
Parties, and the obligations in this Agreement assumed are solely for the use
and benefit of the Parties, their successors in interest and, where permitted,
their assigns.
9.4 Waiver
9.4.1 Except
as otherwise provided in this Agreement, a Party's compliance with any
obligation, covenant, agreement, or condition in this Agreement may be waived
by the Party entitled to the benefits thereof only by a written instrument
signed by the Party granting the waiver, but the waiver or failure to insist
upon strict compliance with the obligation, covenant, agreement, or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent
or other failure.
9.4.2. Failure
of any Party to enforce or insist upon compliance with any of the terms or
conditions of this Agreement, or to give notice or declare this Agreement or
the rights under this Agreement terminated, shall not constitute a waiver or
relinquishment of any rights set out in this Agreement, but the same shall be
and remain at all times in full force and effect, unless and only to the extent
expressly set forth in a written document signed by that Party granting the
waiver or relinquishing any such rights. Any waiver granted, or relinquishment
of any right, by a Party shall not operate as a relinquishment of any other
rights or a waiver of any other failure of the Party granted the waiver to
comply with any obligation, covenant, agreement, or condition of this Agreement.
9.5 Entire Agreement
Except as provided in Article 9.1,
this Agreement, including all attachments, constitutes the entire Agreement
between the Parties with reference to the subject matter of this Agreement, and
supersedes all prior and contemporaneous understandings or agreements, oral or
written, between the Parties with respect to the subject matter of this
Agreement. There are no other agreements, representations, warranties, or
covenants that constitute any part of the consideration for, or any condition
to, either Party's compliance with its obligations under this Agreement.
9.6 Multiple Counterparts
This Agreement may be executed in
two or more counterparts, each of which is deemed an original, but all
constitute one and the same instrument.
9.7 No Partnership
This Agreement shall not be
interpreted or construed to create an association, joint venture, agency
relationship, or partnership between the Parties, or to impose any partnership
obligation or partnership liability upon either Party. Neither Party shall have
any right, power or authority to enter into any agreement or undertaking for,
or act on behalf of, or to act as or be an agent or representative of, or to
otherwise bind, the other Party.
9.8 Severability
If any provision or portion of this
Agreement shall for any reason be held or adjudged to be invalid or illegal or
unenforceable by any court of competent jurisdiction or other governmental
authority, (1) that portion or provision shall be deemed separate and
independent, (2) the Parties shall negotiate in good faith to restore insofar
as practicable the benefits to each Party that were affected by the ruling, and
(3) the remainder of this Agreement shall remain in full force and effect.
9.9 Environmental Releases
Each Party shall notify the other
Party of the release of any hazardous substances, any asbestos or lead
abatement activities, or any type of remediation activities related to the DER
facility or the interconnection facilities, each of which may reasonably be
expected to affect the other Party. The notifying Party shall (1) provide the
notice as soon as practicable, provided that Party makes a good faith effort to
provide the notice no later than 24 hours after that Party becomes aware of the
occurrence, and (2) promptly furnish to the other Party copies of any publicly
available reports filed with any governmental authorities addressing such
events.
9.10 Subcontractors
Nothing in this Agreement shall
prevent a Party from using the services of any subcontractor it deems
appropriate to perform its obligations under this Agreement; provided, however,
that each Party shall require its subcontractors to comply with all applicable
terms and conditions of this Agreement in providing services and each Party
shall remain primarily liable to the other Party for the performance of the
subcontractor.
9.10.1 A
subcontract relationship does not relieve any Party of any of its obligations
under this Agreement. The hiring Party remains responsible to the other Party
for the acts or omissions of its subcontractor. Any applicable obligation
imposed by this Agreement upon the hiring Party shall be equally binding upon,
and shall be construed as having application to, any subcontractor of the
hiring Party.
9.10.2 The
obligations under this Article cannot be limited in any way by any limitation
of subcontractor's insurance.
