PART 466 ELECTRIC INTERCONNECTION OF DISTRIBUTED GENERATION FACILITIES
SECTION 466.60 GENERAL REQUIREMENTS
Section 466.60 General Requirements
a) When an interconnection request for a distributed generation 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 on the basis of the aggregate nameplate capacity of the multiple devices.
b) When an interconnection request is for an increase in capacity for an existing distributed generation facility, the interconnection request shall be evaluated on the basis of the new total nameplate capacity of the distributed generation facility.
c) EDCs shall designate a point of contact and provide contact information on its website. 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 distributed generation facility at a particular point on the EDC's electric distribution system. 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. In appropriate circumstances, the EDC may require a confidentiality agreement prior to release of this information.
e) When an interconnection request is deemed complete by the EDC, any modification that is not agreed to by the EDC requires submission of a new interconnection request.
f) When an applicant is not currently a customer of the EDC at the proposed site, the applicant shall provide, upon EDC 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 or other legally binding contract.
g) To minimize the cost to interconnect multiple distributed generation facilities, the EDC or the applicant may propose a single point of interconnection for multiple distributed generation 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 distributed generation facility. If the EDC, without written 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 distributed generation facility.
h) To protect the safety of the EDC's employees or the reliability of the distribution system, EDCs may require that distributed generation facilities have the capability to be isolated from the EDC. For distributed generation facilities interconnecting to a primary line, the isolation shall be by means of a lockable, visible-break isolation device accessible by the EDC. For distributed generation 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 distributed generation 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 distributed generation facility and located electrically between the distributed generation 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.
i) The interconnection customer shall allow the EDC to isolate the distributed generation 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.
j) Any metering required for a distributed generation 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 distributed generation interconnection agreement executed between the interconnection customer and the EDC.
k) EDC monitoring and control of distributed generation facilities are permitted only when the nameplate rating is greater than 2 MVA. 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.
l) The EDC may require a witness test after the distributed generation facility is constructed. The applicant shall provide the EDC with at least 15 business days' notice of the planned commissioning test for the distributed generation facility. 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. An initial request for extension shall not be denied by the EDC; subsequent requests may be denied. If the applicant fails to address and resolve the deficiencies to the EDC's satisfaction, the interconnection request shall be deemed withdrawn. Even if the EDC or an entity approved by the EDC does not witness a commissioning test, the applicant remains obligated to satisfy the interconnection test specifications and requirements set forth in IEEE Standard 1547 Section 5. The applicant shall, if requested by the EDC, provide a copy of all documentation in its possession regarding testing conducted pursuant to IEEE Standard 1547.1.
m) Each EDC shall allow interconnection applications to be submitted through the EDC's website or via another website if a link is provided on the EDC's website.
n) Each EDC shall dedicate a page on their website to interconnection procedures, that shall include:
1) the EDC's interconnection procedures and attachments in an electronically searchable format;
2) the EDC's interconnection application forms in a format that allows for electronic entry of data;
3) the EDC's interconnection agreements; and
4) the EDC's point of contact for questions about interconnection and submission of interconnection requests, including e-mail and phone number.
o) Each EDC shall allow electronic signatures to be used for interconnection applications.
