PJM EIS' largest focus is to provide the reporting and tracking services of both emissions data and Renewable Energy Credits (RECs) also known as, renewable energy certificates. Services are administrated by PJM EIS through the Generation Attribute Tracking System (GATS), which is owned and operated by PJM EIS.

For generation owners—both large merchant generation owners, and small business or residential generation owners—the GATS tracks the generator’s electric output for the issuance of the applicable RECs. The GATS also tracks the ownership of those RECs through their use by an electric utility for state Renewable Portfolio Standard (RPS) compliance.

Simply put:

  • To generation owners: GATS helps turn generation output into a commodity;
  • To both the electric utilities and owners of certain generators that produce emissions: GATS helps meet government environmental requirements associated with electric operations, such as RPS compliance and emissions disclosure.
