1. 1. All terms defined in Section 466.20 of the Illinois Distributed Energy Resources Interconnection Standard shall have the meanings indicated in that Section when used in this Agreement.
2. 2. Interconnection customer elects and EDC shall cause to be performed an interconnection feasibility study consistent with Section 466.120 of the Illinois Distributed Energy Resources Interconnection Standard.
3. 3. The scope of the interconnection feasibility study shall be based upon the information set forth in the interconnection request application form and Attachment A to this Agreement.
4. 4. The interconnection feasibility study shall be based on the technical information provided by interconnection customer in the interconnection request application form, as modified with the agreement of the Parties. EDC has the right to request additional technical information from interconnection customer during the course of the interconnection feasibility study. If the interconnection customer modifies its interconnection request, the time to complete the interconnection feasibility study may be extended by the EDC.
5. 5. In performing the study, EDC shall rely on existing studies of recent vintage to the extent practical. The interconnection customer will not be charged for such existing studies; however, interconnection customer is responsible for the cost of applying any existing study to the interconnection customer specific requirements and for any new study that the EDC performs.

6. 6. The interconnection feasibility study report shall provide the following information:

   1. 7. Interconnection customer shall provide a study deposit equal to 100% of the estimated non-binding study costs at least 20 business days prior to the date upon which the study commences.
   2. 8. The interconnection feasibility study shall be completed and the results shall be transmitted to interconnection customer within 25 business days after this Agreement is signed by the Parties.
   3. 9. Study fees shall be based on actual costs and will be invoiced to interconnection customer after the study is transmitted to interconnection customer. The invoice must include an itemized listing of employee time and costs expended on the study.

   4. 10. Interconnection customer shall pay any actual study costs that exceed the deposit without interest within 30 calendar days on receipt of the invoice. EDC shall refund any excess deposit amount without interest within 30 calendar days after the invoice.

      In witness whereof, the Parties have caused this Agreement to be duly executed by their duly authorized officers or agents on the day and year first above written.

      Attachment A to Interconnection Feasibility Study Agreement

      Assumptions Used in Conducting the Interconnection Feasibility Study

      The interconnection feasibility study will be based upon the information in the interconnection
      request application form and agreed upon on		:
      	Date

   6.1 Identification of any equipment short circuit capability limits exceeded as a result of the interconnection,

   6.2 Identification of any thermal overload or voltage limit violations resulting from the interconnection, and

   6.3 A description and non-binding estimated cost of facilities required to interconnect the distributed energy resources facility to EDC's electric distribution system as required under Section 466.120(e)(1).

7. 1. Point of interconnection and configuration to be studied.

8. 2. Alternative points of interconnection and configurations to be studied.

   Note: 1 and 2 are to be completed by the interconnection customer. Any additional assumptions (explained below) may be provided by either the interconnection customer or the EDC.

Interconnection Feasibility Study Agreement

Recitals:

Whereas, interconnection customer is proposing to develop a distributed energy resources facility or modifying to an existing distributed energy resources facility consistent with the interconnection request application form submitted by interconnection customer on

Whereas, interconnection customer desires to interconnect the distributed energy resources facility with EDC's electric distribution system; and

Whereas, interconnection customer has requested EDC to perform an interconnection feasibility study to assess the feasibility of interconnecting the proposed distributed energy resources facility to EDC's electric distribution system;

Now, therefore, in consideration of and subject to the mutual covenants contained herein the Parties agree as follows:
