CT: What Are Green Certificates (RECs)? The electricity from all power plants, such as coal, nuclear, natural-gas fired, wind, or solar, and whether in a regulated or competitive market, is mixed together in the transmission and distribution lines that deliver electricity to homes and businesses. Meters measure how much electricity enters the grid from each power plant, as well as how much is used by each end-use customer.
The renewable electricity can be broken into two major parts:

  1. The “energy”, or actual electrical megawatt-hours (MWh) or kilowatt-hours (kWh) delivered into the electrical grid and are common to any power plant, whether powered by a renewable fuel or not.
  2. The renewable “attributes”, or “green certificates“, or “RECs”, representing the positive environmental attributes associated with the MWh or kWh of renewable power delivered to the grid.
