SECTION 466.45 PRE-APPLICATION REPORT


 

Section 466.45  Pre-Application Report

 

a)         A potential applicant may submit a formal written request form along with a non-refundable fee of $300 for a pre-application report on a proposed project at a specific site. The EDC shall provide the pre-application data described in Section 466.50(b) to the potential applicant within 20 business days after receipt of the completed pre-application report request form and payment of the $300 fee. The pre-application report produced by the EDC is non-binding and does not confer any rights; the potential applicant must file an application before it can interconnect with the EDC's system. The written pre-application report request form shall include the following information:

 

1)         project contact information, including name, address, phone number and email address;

 

2)         project location (street address with nearby cross streets and town);

 

3)         meter number, pole number, EDC account number or other equivalent information identifying proposed point of interconnection, if available;

 

4)         generator type (e.g., solar, wind, combined heat and power, battery storage/inverter system and fuel cells);

 

5)         total generation capacity (alternating current kW);

 

6)         single or three phase generator configuration;

 

7)         whether new electric service is required for the site. Include the existing minimum and maximum on-site electrical demand (in kW) and describe any expected changes to the minimum and/or maximum on-site electrical demand (in kW), including the timing of those changes; and

 

8)         number and capacity of each generator unit to be interconnected at the site specified in the pre-application report request.

 

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 and/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)         total capacity (in mega volt amperes (MVA)) of substation/area bus, substation transformer or distribution circuit that the EDC identifies, based on the operating ratings that the EDC expects would apply to these facilities if used to serve the proposed point of interconnection;

 

2)         existing aggregate generation capacity (i.e., amount of generation online, in MVA) interconnected to the substation/area bus, substation transformer or distribution circuit that the EDC identifies;

 

3)         aggregate queued generation capacity (i.e., amount of generation in the queue, in MVA) for the substation/area bus, substation transformer or distribution circuit that the EDC identifies;

 

4)         available capacity (i.e., total capacity less the sum of existing aggregate generation capacity and aggregate queued generation capacity, in MVA) of substation/area bus, substation transformer or distribution circuit that the EDC identifies;

 

5)         nominal operating voltages of substation/area bus, substation transformer and/or distribution circuit that the EDC identifies;

 

6)         nominal operating voltage of the identified distribution circuit at the proposed point of interconnection;

 

7)         approximate circuit distance between the proposed point of interconnection and the identified substation/area bus;

 

8)         relevant line sections actual or estimated peak load and minimum load data, including daytime minimum load (i.e., minimum load from 10 a.m. to 4 p.m. for fixed panel photovoltaic systems and from 8 a.m. to 6 p.m. for photovoltaic (PV) systems utilizing tracking systems), and absolute minimum load, when available;

 

9)         number and rating of protective devices and number and type (standard, bi-directional) of voltage regulating devices between the proposed point of interconnection and the substation/area bus that the EDC identifies;

 

10)        whether the identified substation transformer uses a load tap changer;

 

11)        number of phases available at the proposed point of interconnection.  If a single phase, the distance from the proposed point of interconnection to the EDC's three-phase distribution circuit;

 

12)        limiting conductor ratings from the proposed point of interconnection to the distribution substation;

 

13)        whether the point of interconnection is located on a spot network, grid network or radial supply; and

 

14)        based on the proposed point of interconnection, existing or known constraints such as, but not limited to, electrical dependencies at that location, short circuit interrupting capacity issues, power quality or stability issues on the circuit, capacity constraints or secondary networks.

 

c)         The pre-application report need only include existing data. A pre-application report request does not obligate the EDC to conduct a study or other analysis of the proposed generator in the event that data is not available. If some of the data is not available, the EDC shall provide the interconnection customer with a pre-application report that includes the data that is available. The information concerning "available capacity" provided pursuant to subsection (b)(4) does not imply that an interconnection up to this level may be completed without impacts, because there are many variables studied as part of the interconnection review process, and data provided in the pre-application report may become outdated by the time the complete application is submitted. Notwithstanding any of the provisions of this Section, the EDC shall, in good faith, include data in the pre-application report that represents the best available information at the time of reporting.
