Brattle Study

California’s SB 100 bill has committed the state to decarbonize its power grid with a goal of 60% renewable energy by 2030 and 100% clean electric retail sales by 2045. Plans and resource procurements are falling into place to pursue those goals, including through the California Public Utilities Commission’s (CPUC’s) recent Mid-Term Reliability Procurement Order and the ongoing Integrated Resource Plan and Long Term Procurement Plan.

The Brattle Group’s full analysis is available here and a shorter public briefing summary here.
