Tracking systems thus create a record of generation that contains a variety of information useful or necessary to determine the REC's eligibility in compliance markets or its desirability in voluntary markets. Therefore, the tracking systems serve as essential verification tools to help prevent double-selling of RECs and support credible REC markets. Figure 2 shows certificate tracking systems in operation and those under development or discussion.
REC Tracking Systems that are in operation today are found in New England (NEPOOL Generation Information System) and the states of Texas, Wisconsin, and the Canadian province of Manitoba. Stakeholders are currently developing design criteria for the PJM Generation Attributes Tracking System (GATS) and the Western Renewable Energy Generation Information System (WREGIS), a regional effort including 11 Western U.S. states, 2 Canadian provinces, and Northern Baja. Also, tracking systems are under discussion in
Ontario, New York (as part of the RPS rulemaking), and in the Upper Midwest states of Minnesota, North Dakota, South Dakota, Iowa, and Wisconsin.
