Renewables Portfolio Standard (RPS) Verification

Under California's Renewables Portfolio Standard (RPS) statutes, procurement claims from a RPS certified facility must be verified as eligible for the RPS in order to count towards a utility's RPS obligation. The Western Renewable Energy Generation Information System (WREGIS) has been developed to satisfy current RPS tracking requirements. The use of WREGIS is required for retail sellers and publicly owned utilities to track and report their RPS procurement.

Retail sellers and publicly owned utilities must report their RPS claims annually to the Energy Commission on July 1st of each year.

RPS-eligible facilities that use one or more non-renewable fuel must report their monthly fuel use data annually to the Energy Commission by April 1st of each year for the previous calendar year. RPS-eligible facilities using common carrier pipeline biomethane must report their biomethane data by April 1st of each year for the previous calendar year.
