Accounting for Green Energy.

The CEC is introducing a tracking system and registry for renewable energy produced and deposited on the grid. The system, called WREGIS (Western Renewable Energy Generation Information System), is designed to measure the actual production and use of green energy.

According to a report in North America Windpower:

“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.”
