The Western Renewable Energy Generation Information System (WREGIS) is an independent, renewable energy database for the region covered by the Western Interconnection. WREGIS creates renewable energy certificates (WREGIS certificates) for verifiable renewable generation from units that register in the database.
WREGIS was developed as a collaborative process between the Western Governors’ Association, the Western Regional Air Partnership, and the California Energy Commission. The development was further guided by stakeholder input from more than 400 participants gathered over a period of more than three years.
WREGIS is governed by a seven member committee consisting of representatives from various stakeholder groups. Interested parties can participate by joining the Stakeholder Advisory Committee (SAC).
