Connecticut solar and battery programs.

Residential Renewable Energy Solutions (RRES), with Buy-All and Netting tariffs

Home solar owners choose one of two 20-year options. With Buy-All, the utility buys all the power your system makes. With Netting, you use your own power first and get bill credits for what you send to the grid.

2026 Buy-All: $0.3289 per kWh. 2026 Netting: retail-rate credit for exports, a $0.000 REC rate, and a $0.0402 per kWh charge on total generation. Adders: low-income $0.055 (Buy-All) or $0.035 (Netting); economically distressed municipality $0.0275 (Buy-All) or $0.0175 (Netting). A system can take only one adder.

Date of this figure: Program Manual Version 2026.1, effective January 1, 2026; applies to interconnection applications from January 1 to December 31, 2026.
