Net Energy Tariff Rates

The Commission will establish tariff rates by January 1 each year for the Net Energy Tariff Rate Program.

Customers participating in this program will receive a bill credit equal to the tariff rate multiplied by the customer’s share of the facility output during the applicable period. The bill credit shall apply against the total amount of the bill issued to the customer by the transmission and distribution utility, but may not result in a negative customer bill. Unused credits expire after 12-months.
