4928.67 Standard contract or tariff providing for net energy metering.

(A)

(1) Except as provided in division (A)(2) of this section, an electric utility shall develop a standard contract or tariff providing for net metering. That contract or tariff shall be identical in rate structure, all retail rate components, and any monthly charges to the contract or tariff to which the same customer would be assigned if that customer were not a customer-generator.

(2) An electric utility shall also develop a separate standard contract or tariff providing for net metering for a hospital, as defined in section 3701.01 of the Revised Code, that is also a customer-generator, subject to all of the following:

(a) No limitation, including that in divisions (A)(31)(a) and (d) of section 4928.01 of the Revised Code, shall apply regarding the availability of the contract or tariff to such hospital customer-generators.

(b) The contract or tariff shall be based both upon the rate structure, rate components, and any charges to which the hospital would otherwise be assigned if the hospital were not a customer-generator and upon the market value of the customer-generated electricity at the time it is generated.

(c) The contract or tariff shall allow the hospital customer-generator to operate its electric generating facilities individually or collectively without any wattage limitation on size.

(B)

(1) Net metering under this section shall be accomplished using a single meter capable of registering the flow of electricity in each direction. If its existing electrical meter is not capable of measuring the flow of electricity in two directions, the customer-generator shall be responsible for all expenses involved in purchasing and installing a meter that is capable of measuring electricity flow in two directions.

(2) The electric utility, at its own expense and with the written consent of the customer-generator, may install one or more additional meters to monitor the flow of electricity in each direction.

(3) Consistent with the other provisions of this section, the measurement of net electricity supplied or generated shall be calculated in the following manner:

(a) The electric utility shall measure the net electricity produced or consumed during the billing period, in accordance with normal metering practices.

(b) If the electricity supplied by the electric utility exceeds the electricity generated by the customer-generator and fed back to the utility during the billing period, the customer-generator shall be billed for the net electricity supplied by the utility, in accordance with normal metering practices. If electricity is provided to the utility, the credits for that electricity shall appear in the next billing cycle.

(4) A net metering system used by a customer-generator shall meet all applicable safety and performance standards established by the national electrical code, the institute of electrical and electronics engineers, and underwriters laboratories.

(C) The public utilities commission shall adopt rules relating to additional control and testing requirements for customer-generators that the commission determines are necessary to protect public and worker safety and system reliability.

(D) An electric utility shall not require a customer-generator whose net metering system meets the standards and requirements provided for in divisions (B)(4) and (C) of this section to do any of the following:

(1) Comply with additional safety or performance standards;

(2) Perform or pay for additional tests;

(3) Purchase additional liability insurance.
