The APX system will track and register WREGIS Certificates that will be the basis for renewable energy certificate trading across the Western Electricity Coordinating Council region. With a footprint of 1.8 million square miles and members operating in 14 states in the Western U.S., two Canadian provinces, and the Northern portion of Baja, Mexico, WECC is the largest of the eight North American Electric Reliability Council regions.
A web-based hosted system, the APX system creates and tracks a unique, traceable digital certificate for every MWh of renewable energy generated by generating units registered with WREGIS or imported into WREGIS. Retail electric suppliers use the system’s certificates to report compliance with regulatory requirements set by the states and provinces, including power purchases to meet Renewable Portfolio Standards (RPS), or with voluntary renewable energy program requirements. The system also records ownership and facilitates transfers of the certificates to support the operation and integrity of renewable energy and environmental markets.
