.06 General Requirements.

A. If an interconnection request for a small generator 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. If an interconnection request is for an increase in capacity for an existing small generator facility, the interconnection request shall be evaluated on the basis of the new total nameplate capacity of the small generator facility.

C. Utility Provided Information.

(1) A utility shall designate a contact person, and provide contact information on its website and for the Commission's website for submission of all interconnection requests, and from whom information on the interconnection request process and the utility's electric distribution system can be obtained.

(2) The information provided by the utility on its website shall include studies and other materials useful to an understanding of the feasibility of interconnecting a small generator facility on the utility electric distribution system, except to the extent providing the materials would violate security requirements or confidentiality agreements, or be contrary to law.

(3) In appropriate circumstances, the utility may require an applicant to execute an appropriate confidentiality agreement prior to release or access to confidential or restricted information.

D. If an interconnection request is determined to be complete, a modification, other than a minor equipment modification that is not agreed to in writing by the utility, shall require submission of a new interconnection request.

E. If an applicant is not currently a customer of the utility at the location for the proposed generation facility, upon request from the utility, the applicant shall provide proof of site control evidenced by a property tax bill, deed, lease agreement, contract, or other acceptable document.

F. Connection of Multiple Small Generators by Single Interconnection.

(1) To minimize the cost of interconnecting multiple small generator facilities, the utility or the applicant may propose a single point of interconnection for multiple small generator facilities located at a single site.

(2) If an applicant rejects a utility proposal for a single point of interconnection, the applicant shall pay any additional cost of providing separate points of interconnection for each small generator facility.

(3) If a utility unreasonably rejects a customer proposal for a single point of interconnection without providing a written technical explanation, the utility shall pay any additional cost of providing separate points of interconnection for each small generator facility.

G. Electrical Isolation of Generators.

(1) Small generator facilities shall be capable of being isolated from the utility distribution system.

(2) For small generator facilities interconnecting to a primary line, the isolation shall be by means of a lockable, visible-break isolation device accessible by the utility.

(3) For small generator facilities interconnecting to a secondary line, the isolation shall be by means of a lockable isolation device whose status is clearly indicated and is accessible by the utility.

(4) The isolation device shall be installed, owned, and maintained by the owner of the small generation facility, and located electrically between the small generation facility and the point of interconnection.

(5) A draw-out type circuit breaker with a provision for padlocking at the draw-out position satisfies the requirement for an isolation device.

H. Use of Lockbox for Access to Isolation Device.

(1) An interconnection customer may elect to provide the utility access to an isolation device that is contained in a building or area that may be unoccupied and locked or not otherwise readily accessible to the utility, by installing a lockbox provided by the utility that shall allow ready access to the isolation device.

(2) The lockbox shall be in a location that is readily accessible by the utility, and the interconnection customer shall permit the utility to affix a placard in a location of its choosing that provides clear instructions to utility operating personnel on access to the isolation device.

(3) In the event the interconnection customer fails to comply with the terms of this section and the utility needs to gain access to the isolation device, the utility may not be held liable for any damages resulting from any necessary utility action to isolate the small generator.

I. Metering.

(1) Any metering necessitated by a small generator interconnection shall be installed, operated, and maintained in accordance with the applicable utility tariff.

(2) Any small generator metering requirements shall be clearly identified as part of the standard small generator interconnection agreement executed by the interconnection customer and the utility.

J. Utility Monitoring and Control of Small Generator.

(1) Utility monitoring and control of a small generator facility shall be permitted only if the nameplate rating is greater than 2 MW.

(2) Any monitoring and control requirements shall be:

(a) Consistent with the utility published requirements; and

(b) Clearly identified as part of an interconnection agreement executed by the interconnection customer and the utility.

K. Witness Test of Small Generator.

(1) The utility shall have the option of performing a witness test after construction of the small generator facility is completed.

(2) The applicant shall provide the utility at least 5 business days notice of the planned commissioning test for the small generator facility.

(3) If the utility elects to perform a witness test, the utility shall contact the applicant to schedule the witness test at a mutually agreeable time within 10 business days of the scheduled commissioning test.

(4) If the utility does not perform the witness test within 10 business days of the commissioning test, the witness test is considered waived unless the utility and applicant agree to extend the time for conducting the witness test.

(5) If the results of the witness test are not acceptable to the utility, the applicant shall address and resolve any deficiencies within 30 business days, which may be extended upon the request of the applicant prior to the expiration of the 30 business day period. A request for extension may not be unreasonably denied by the utility.

(6) If the applicant fails to address and resolve the deficiencies to the satisfaction of the utility, the interconnection request shall be considered withdrawn.

(7) If a witness test is not performed by the utility or an entity approved by the utility, the applicant shall satisfy the interconnection test specifications and requirements set forth in Section 5 of IEEE Standard 1547.

(8) For interconnection equipment that has not been lab-certified or field-approved under Regulation. 07 of this chapter, the witness test shall also include the verification by the utility of the on-site design tests as required by Section 5.1 of IEEE Standard 1547 and of production tests required by Section 5.2 of IEEE Standard 1547.

(9) All tests verified by the utility shall be performed in accordance with the test procedures specified in IEEE Standard 1547.1.

(10) The applicant shall, if requested by the utility, provide a copy of all documentation in its possession regarding testing conducted under IEEE Standard 1547.1.

L. Interconnection Studies and Applicant Information.

(1) If requested by the applicant, the utility shall provide the applicant copies of any interconnection studies performed in analyzing an interconnection request.

(2) An applicant may provide any other prospective applicant copies of interconnection studies to aid in streamlining a future utility review.

(3) A utility has no obligation to provide any prospective applicant any information regarding prior interconnection requests, including a prior applicant's name, copies of prior interconnection studies performed by the utility, or any other information regarding a prior applicant or request.
