Renewable Energy Credits

An Opportunity to Develop Renewable Generation in Connecticut Through the Low Emission Renewable Energy Credit (LREC) and Zero Emission Renewable Energy Credit (ZREC) Program.

Electric customers of Eversource in Connecticut who install new, qualifying renewable energy projects -- ranging from rooftop solar panels to fuel cells -- now have an opportunity to sell the qualified Connecticut Class I renewable energy credits (RECs) created from their projects to Eversource under a long-term, 15-year contract.
