California will target 25.5 GW of new supply-side renewable energy and 15 GW of new storage and demand-response resources by 2032, according to a long-term plan approved last week by the California Public Utilities Commission (CPUC).

The regulator has adopted a preferred systems program designed to ensure power reliability and achieve targeted greenhouse gas (GHG) emissions reductions in the power sector.

The CPUC said that the preferred combination of system solutions includes more solar and battery storage than previously adopted system solutions. It also includes new long-term storage, out-of-state and offshore wind resources.

The portfolio adopted includes 17,506 MW of utility-scale solar, 13,571 MW of battery storage, 3,531 MW of wind, as well as offshore wind, "new out-of-state transmission wind", geothermal, pumped hydro, shed demand Response and biomass resources.

According to provisional estimates, the transmission system will be able to accommodate the new resource, requiring only limited upgrades by 2032.

The committee has adopted a planning target of 35 million tonnes of greenhouse gases for the power sector by 2032. According to the announcement, this is more stringent than the previously adopted GHG target of 46 million tonnes, which equates to 73% Renewable Portfolio Standard (RPS) resources and 86% GHG-free resources by 2032.

Commissioner Clifford Reichshefen said: "Today's decision provides direction to procure an unprecedented amount of new clean energy resources. It allows us to continue working towards achieving our country's ambitious clean energy goals while ensuring system reliability. step forward."

California's goal is to generate 100 percent of its electricity from clean energy by 2045.
