Indiana Administrative Code
Title 170 - INDIANA UTILITY REGULATORY COMMISSION
Article 4 - ELECTRIC UTILITIES
Rule 4.2 - Net Metering
Section 4.2-7 - Billing

(1) Bill charges, credits, rates, and adjustments shall be in accordance with the investor-owned electric utility's tariff and administrative rules that would apply if the net metering customer did not participate in net metering.

(2) The investor-owned electric utility shall measure the difference between the amount of electricity delivered by the investor-owned electric utility to the net metering customer and the amount of electricity generated by the net metering customer and delivered to the investor-owned electric utility during the billing period, in accordance with normal metering practices. If the kilowatt hours (kWh) delivered by the investor-owned electric utility to the net metering customer exceed the kWh delivered by the net metering customer to the investor-owned electric utility during the billing period, the net metering customer shall be billed for the kWh difference at the rate applicable to the net metering customer if it was not a net metering customer. If the kWh generated by the net metering customer and delivered to the investor-owned electric utility exceed the kWh supplied by the investor-owned electric utility to the net metering customer during the billing period, the net metering customer shall be credited in the next billing cycle for the kWh difference.

(3) The credit shall roll over indefinitely for net metering customers, except that when the net metering customer elects to no longer participate in the net metering tariff, all unused credit shall revert to the investor-owned electric utility.
