June 2007 - The Western Renewable Energy Generation Information System (WREGIS), a renewable energy registry and tracking system for electricity generation in the western United States, and parts of Canada and Baja California, is now operational. The system, which is being administered by the Western Electricity Coordinating Council (WECC), will be used to track compliance with state and provincial renewable energy requirements, as well as to facilitate voluntary market purchases, within the Western Interconnection transmission area.
Data in WREGIS includes megawatt-hours (MWh) produced, fuel source, facility location, and all state, provincial and voluntary renewable energy program qualifications. One WREGIS certificate is issued for each MWh of renewable energy produced and deposited on the grid. To prevent double counting, each WREGIS certificate has its own unique serial number. Participation in the system is voluntary.
