CT's Renewable Energy Standards

The Renewable Energy In Your Generation Supply
 
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.

CT's Minimum Renewable Energy Requirements

All electricity sold in Connecticut includes a mandatory amount of renewable energy, referred to as Connecticut's  Renewable Portfolio Standard or RPS. In 2018, the minimum is 25% which increases annually to 28% in 2020. Learn how other states support renewable energy.

Eversource and UI Standard Service generation supply meets this minimum. The utilities do not offer a generation supply option that exceeds the minimum.

Some suppliers offer plans that exceed CT's renewable standard. The Rate Board displays the percentage of renewable energy for each offer. Speak directly with the supplier to learn more about offers that exceed the minimum and the type of renewable energy they buy to market these offers. The utilities and licensed suppliers buy or trade Renewable Energy Certificates (REC) to meet meet these standards.

Renewable Energy Certificates

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.

Disclosure Label

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.   

CT's Clean Energy Options Program

The Connecticut Clean Energy Options Program currently is extended until the Public Utilities Regulatory Authority (PURA) creates a successor program, reviewed under PURA Docket No. 16-12-29, PURA Development of Voluntary Renewable Options Program. 

Contact the Public Utilities Regulatory Authority (PURA) for Information or to File a Complaint

If you have a question about choosing an electric supplier or wish to file a complaint about a licensed supplier you can:

Shared Clean Energy Facility

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. 

Review the Eversource SCEF tariff or the United Illuminating SCEF tariff.

PURA is reviewing similar programs under Docket No. 19-07-01, Review of Statewide Shared Clean Energy Facility Program Requirements.

Solar Options in CT

Own Cash - Payback is reduction it electric costs 5 to 7 years depending on size, orientation.  Greatest return.

Loan - Similar to cash - depends on interest rate.  e.g. home equity.

PPA - Payment based on output - follows production/degredation

Lease - fixed monthly payment - degredation - lease payment does not decrease to match production
