Welcome to WREGIS

The Western Renewable Energy Generation Information System (WREGIS) is an independent, renewable energy tracking system for the region covered by the Western Electricity Coordinating Council (WECC). WREGIS tracks renewable energy generation from units that register in the system using verifiable data and creates renewable energy certificates (RECs) for this generation. WREGIS Certificates can be used to verify compliance with state and provincial regulatory requirements (Renewable Portfolio Standards, for example) and in voluntary market programs. Learn More >>
