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 2017, the minimum is 22.5% which increases annually to 27% 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.
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 CTCleanEnergyOptions Progam allows you to support renewable energy by paying an additional cost per kWh through your Eversource or UI bill. The CTCleanEnergyOptions program administrators use the fee you pay to purchase Renewable Energy Certificates to match the amount of electricity you use.
