If you own a renewable energy resource, you're probably looking to capture value from it. PJM-EIS offers the Generation Attribute Tracking System (GATS) which helps resource owners earn revenue through a unique market. GATS enables resource owners to convert power into a tradable Renewable Energy Certificate (REC). A REC is created for every megawatt-hour of electricity generated. Anyone who registers a certified generator in GATS can sell their RECs. Registering a generator begins by looking at the state program information.
