Information about the renewable energy used to generate the electricity sold in Connecticut, renewable energy plans offered by licensed suppliers, the system that tracks New England's renewable energy certificates and more.
All electricity sold in Connecticut by UI, Eversource and licensed suppliers includes a mandatory amount of Renewable Energy Certificates (REC), referred to as Connecticut's Renewable Portfolio Standard or RPS.
UI, Eversource and licensed suppliers purchase Renewable Energy Certificates to meet the RPS. In 2021, the minimum RPS is 30.5% which increases annually to 48% in 2030. Learn how other states support renewable energy.
Some suppliers offer plans that exceed Connecticut's minimum renewable standard and purchase additional RECs for these offers. The Rate Board displays the percentage of renewable energy certificates for each offer.
Speak with the supplier to learn more about offers that exceed the minimum and ask about the type of renewable energy certificate the supplier purchases to support these offers. Also ask where the renewable resource is located (e.g., Texas, Midwest) and type of resource (e.g., wind, solar, trash-to-energy).
Eversource and UI Standard Service generation supply meets the minimum RPS. The utilities do not offer a generation supply option that exceeds the minimum.
However, customers taking Standard Service generation supply can support additional Renewable Energy Certificates through the Clean Energy Options Program.
A Renewable Energy Certificate, or REC, is issued for each Megawatt-hour (MWh) of energy generated from certain clean or renewable sources or for each MWh of energy saved through the installation of energy efficiency measures.
RECs can be sold or traded to fulfill the state's Renewable Portfolio Standards (RPS) obligation. The Independent System Operator of New England (ISO-NE) manages the Generation Information System (GIS) which tracks the RECs that are created in New England. RECs are also created throughout the United States. Suppliers use regional and national RECs to market offers that exceed CT's minimum renewable energy requirements.
Connecticut requires licensed suppliers to use a Disclosure Label to display the source of generation, emissions, renewable energy and RECs for each generation supply offer. The Disclosure Label is provided with each contract for service and contains the information consumers need to understand how their electricity is generated and to learn about the renewable energy used to market generation supply offers that exceed Connecticut's minimuim requirements.
A Disclosure Label provides information about the source of generation and related air emissions for electricity sold to end use customers in Connecticut.
The Public Utilities Regulatory Authority approves the Disclosure Label that suppliers are required to provide with every contract for generation supply.
The Independent System Operator of New England (ISO-NE) maintains real-time information about the sources of generation used to meet the day-to-day electricity produced in New England, sometimes called the system mix. This information is displayed on the ISO-NE home page
Eligible residential and business customers may participate in the Shared Clean Energy Facilities program, also referred to as SCEF.
The Public Utilities Regulatory Authority (PURA) approved a SCEF pilot program under PURA Docket No. 17-06-28, Application to Approve the Selected Projects Under the Shared Clean Energy Facility Pilot Program. Learn more about the pilot program and the approved SCEF pilot installations and vendors.
PURA approved rules for future SCEF programs under Docket No. 19-07-01, Review of Statewide Shared Clean Energy Facility Program Requirements. See, PURA Final Decision.
