Renewables Portfolio Standard (RPS)

The Renewable Portfolio Standard (RPS) was established in 2002 under Senate Bill 1078 and accelerated in 2006 under Senate Bill 107. In 2011, it was accelerated again under Senate Bill 2 (1x), requiring investor-owned utilities (IOUs), electric service providers (ESPs), and community choice aggregators (CCAs) to increase their purchase of eligible renewable energy resources to 33% by 2020.

Assembly Bill 327 provided the CPUC with the authority to establish a higher procurement target beyond the existing 33% target.

In September 2015, Senate Bill 350 was signed into law, increasing RPS to 50% by 2030. The CPUC is addressing the new RPS target in its RPS Rulemaking proceeding. SB 350, the Clean Energy and Pollution Reduction Act of 2015, increases the RPS target from 33% to 50% by 2030, with interim targets of 40% by the end of 2024, and 45% by the end of 2027.
