CPUC Decision Calls for 1,000 MW of New, “Firm” Renewables, Including Bioenergy

The CPUC’s Decision calls for 11,500 MW of new renewable power generation to offset the closure of California’s last nuclear power plant and several natural gas plants along the coast that use “once-through cooling.”  The Decision also calls for 1,000 MW from “firm” renewable power – bioenergy and geothermal – that is available when needed and has a capacity factor of at least 80 percent (is in operation 80% of the time throughout the year).  The new generation must be online by the end of 2026.

The requirement for firm renewable power begins on page 35 of the CPUC’s Decision on Mid-Term Reliability Procurement.

CalMatters: CA Needs Bioenergy and Green Hydrogen for Reliability

CalMatters has published an opinion piece by BAC’s Executive Director that highlights the need for bioenergy and green hydrogen to maintain a reliable and renewable power grid.  The piece underscores the importance of bioenergy and green hydrogen to complement solar, wind and batteries, to provide long duration energy storage and flexible generation power, and to provide renewable fuel for microgrids and backup generators.  The piece makes clear that California can have a 100 percent renewably powered grid, but needs both bioenergy and green hydrogen to ensure that power supplies remain reliable.

California Legislature Adopts 60 Percent RPS !!

In late August, the California Legislature passed SB 100 (de Leon), which increases California’s renewable electricity (RPS) requirement from 50 to 60 percent by 2030.  SB 100 also requires the California Public Utilities Commission to plan for 100 percent of the state’s electricity to come from RPS eligible or zero carbon power by 2045.  These two provisions will help to keep renewable power growing in California and will force the CPUC to plan for a more diverse portfolio of resources to meet the 100 percent target in 2045.

National Academy of Sciences Paper Underscores Need for Bioenergy

Some energy advocates and environmental groups have been claiming that the U.S. can meet all its energy needs with solar, wind and energy storage. The National Academy of Sciences has released a paper that criticizes that view as likely to be dangerously expensive if achievable at all. The NAS paper strongly recommends the inclusion of bioenergy in a low carbon portfolio to provide power that is easily dispatchable (available when needed) and that can be carbon negative.
