SECTION 467.45 PRE-APPLICATION REPORT


 

Section 467.45  Pre-Application Report

 

a)         In addition to the information described in Section 467.60, which may be provided in response to an informal request, 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 this Section to the potential applicant within 20 business days after receipt of the completed 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 successfully file an application before it can interconnect with the EDC's system. The written pre-application report request form shall include the following information to clearly and sufficiently identify the location of the proposed point of interconnection:

 

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

 

2)         project location (street address with nearby cross streets, town, and GPS coordinates in decimal format);

 

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

 

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

 

5)         size (alternating current kW);

 

6)         single or three-phase generator configuration;

 

7)         whether a stand-alone generator is proposed (no onsite load, not including station service);

 

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

 

9)         the 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 shall identify the substation/area bus, bank or circuit likely to serve the proposed point of interconnection. This selection by the EDC does not necessarily indicate, after application of the relevant review process, that this would be the circuit to which the project ultimately connects.  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:

 

A)        Substation and circuit identifying information;

 

B)        Feeder configuration (e.g., radial or network);

 

C)        Number and size of phase conductors at the point of interconnection;

 

D)        Distance to three-phase (if applicable);

 

E)        Primary circuit voltage at the point of interconnection;

 

F)         Existing aggregate generation capacity interconnected to the identified substations and circuits;

 

G)        Aggregate generation capacity and non-binding estimated costs associated with projects earlier in the queue and planned for the identified substations and circuits;

 

H)        Capacity of the substation transformer, substation circuit equipment, and lowest rated circuit equipment between the proposed point of interconnection and the substation/area bus identified;

 

I)         Circuit peak and minimum load:  estimated if actual is unavailable (i.e., minimum load from 10 a.m. to 4 p.m. Central Prevailing Time for fixed panel photovoltaic (PV) systems, from 8 a.m. to 6 p.m. for PV systems using tracking systems, or absolute minimum for non-PV and energy storage systems);

 

J)         Approximate circuit distance between the proposed point of interconnection and the identified substation or area bus;

 

K)        Size and type of relevant protective devices between the proposed point of interconnection and the substation/area bus identified, including:

 

i)          Lowest rated upstream recloser, where applicable; and

 

ii)         Lowest rated upstream fuse, where applicable;

 

L)        Number of regulating devices between the proposed point of interconnection and the substation/area bus identified; and

 

M)       For the EDC's proposed point of interconnection, all existing or anticipated constraints that might affect the interconnection.

 

2)         Disclosure from the EDC as to whether the aggregate contingent upgrades of the systems earlier in the queue are estimated to exceed the following thresholds, if such estimates are available:

 

A)        Distribution facility replacement/upgrades of $50,000;

 

B)        Substation transformer replacement/upgrades of $100,000; or

 

C)        Transmission replacement/upgrades of $100,000.

 

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 readily available. If the EDC cannot complete all or some of a pre-application report due to lack of available data, the EDC shall provide the interconnection customer with a pre-application report that includes the data that is available. The provision of information on "available capacity" within the pre-application report represents the best information available to the EDC at the time of the reporting and does not imply that an interconnection up to this level may be completed without impacts.
