R746-312-14. Requirements After Interconnection Approval

(1) A public utility may not require an applicant whose facility meets the criteria for interconnection approval under the Level 1 or Level 2 interconnection review procedures to perform or pay for additional tests, except if agreed to by the applicant. In addition, a public utility may not require an interconnection customer whose net metering generating facility is in compliance with Section 54-15-106 to perform or pay for additional tests.

(2) A public utility may not charge any fee or other charge for connecting to the public utility's distribution system or for operation and maintenance of a generating facility for the purposes of generating electricity, except for the fees provided for under this interconnection rule and approved standard form agreements or determined by the governing authority.

(3) Once an interconnection has been approved under this interconnection rule, the public utility may not require an interconnection customer to test or perform maintenance on its facility except for the following and subject to the provision of Section 54-15-106:

(a) any manufacturer-required testing or maintenance;

(b) any post-installation testing necessary to ensure compliance with IEEE standards or to ensure safety;

(c) the interconnection customer replaces a major equipment component that is different from the originally installed model; and/or

(d) an annual test to be performed at the discretion of and paid for by the public utility in which the generating facility is disconnected from the public utility's equipment to ensure the inverter stops delivering power to the grid.

(4) When an approved generating facility undergoes maintenance or testing in accordance with the requirements of this interconnection rule, the interconnection customer must retain written records for three years documenting the maintenance and the results of testing.

(5) A public utility has the right to inspect an interconnection customer's facility after interconnection approval is granted, at reasonable hours and with reasonable prior notice to the interconnection customer. If the public utility discovers that the generating facility is not in compliance with the requirements of this interconnection rule or executed agreements, the public utility may require the interconnection customer to disconnect the generating facility until compliance is achieved.

(6) Subsequent to becoming interconnected to a public utility the interconnection customer must notify the public utility of all proposed modifications to the generating facility or equipment package pursuant to Subsection R746-312-4(6).
