Solar Connecticut Inc. filed an interim solar residential tariff with the Connecticut Public Utilities Regulatory Authority following legislation enacted in May 2018 requiring the agency to establish procurement plans and tariffs for projects selected under the plans for each electric distribution company. The law grandfathered existing net metering customers through 2039 and ended the program on Dec. 31, 2018, leaving new residential customers to select a “buy-all, sell-all” tariff option under which utilities buy all energy generated by the customer’s system on a fixed cents-per-kilowatt-hour basis and the customer pays retail rates for all energy consumed. The agency opened a docket to create tariffs for energy and renewable energy certificates generated by selected projects, as well as purchase of such credits from Class I residential facilities up to 25 kW.

Solar Connecticut requests that the tariff become effective before the termination of the Green Bank’s residential solar investment program that has a goal of achieving 300 megawatts of solar by 2022. The company said that the lack of infrastructure and billing capabilities necessitates an interim plan until a final tariff can be fully implemented. The proposal details project eligibility criteria, purchase commitment terms, and compensation mechanisms.
