On June 2, 2021, the California Energy Commission, in collaboration with the California Public Utilities Commission and the California Independent System Operator (“Joint Agencies”), hosted a workshop to discuss the next steps to meet the requirements of California Senate Bill 100 (“SB 100”).  This workshop built upon the Joint Agencies’ March 2021 report, which found that 145 GW of solar, wind, and storage must be added to the California grid to achieve 100 percent renewable electricity by 2045.  To plan for this unprecedented resource build, the Joint Agencies brought together stakeholders from across the industry to discuss anticipated challenges and proposed solutions.

Participants in the workshop expressed their commitment to building toward a 100 percent carbon-free electricity grid.  Representatives from publicly owned utilities, investor owned utilities, and a community choice aggregator underscored the current progress in deploying renewables and retiring fossil fuel-powered generation.  Some service providers plan to achieve the SB 100 goals a decade or more ahead of the 2045 goal.  Workshop participants also highlighted the challenges that must be overcome to realize California’s ambitious energy transition, raising concerns about reliability, affordability, and transmission constraints.  Additionally, several panelists contended there is a lack of concrete options to replace the functionality of natural gas-fired generation.  Panelists suggested potential solutions such as making more efficient use of existing transmission and increasing customer engagement around demand response. 

Written public comments may be submitted here until Tuesday, June 22, 2021.
