An electric company shall offer net energy metering service to an eligible customer-generator under a Commission-approved standard contract or tariff. An electric company’s tariff or contract for net metering shall contain an energy rate, a rate structure, and any monthly charge identical to the monthly contract or tariff charge paid by a customer of the rate class in which the eligible customer-generator would be a member if they were not receiving net energy metering service. An electric company may not include in an eligible customer-generator’s bill rates, charges or fees that raise the eligible customer-generator’s minimum monthly charge above that of customers of the same rate class to which the eligible customer-generator would otherwise be assigned. An electric company may not charge to an eligible customer-generator new or additional demand charges, standby charges, customer charges, or minimum monthly charges. An electric company may not require an eligible customer-generator whose electric generating system meets the requirements of this chapter to: Install additional controls; Perform or pay for additional tests; or Purchase additional liability insurance.
