The California Energy Commission has introduced the Western Renewable Energy Generation Information System (WREGIS), a renewable energy registry and tracking system for electricity generation. WREGIS will track the renewable generation to help ensure the credibility of the green value of renewable electricity, the California Energy Commission explains.
Data in WREGIS include 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. The California Energy Commission notes that to prevent double counting in the system, each WREGIS certificate has its own unique serial number.
"The WREGIS system is a critical element in measuring California s success as we move forward to reaching the mandate to generate 20 percent of our electricity from renewable energy by 2010," says Jackalyne Pfannenstiel, chair of the California Energy Commission. "California is also serious about achieving our goal of generating 33 percent of our electricity from renewable energy by 2020. With WREGIS, we can manage the many transactions that will allow us to achieve the mandate as we track our success."
According to the California Energy Commission, WREGIS will be available in the area covered by the Western Interconnection System, which includes Washington, Oregon, California, Nevada, Idaho, Utah, New Mexico, Arizona, Colorado, Wyoming, Montana, Texas, South Dakota, Nebraska, British Columbia, Alberta and the northern portion of Baja California.
