On May 18, 2023, the California Independent System Operator (CAISO) Board of Governors approved the 2022-2023 Transmission Plan by a unanimous vote. The Transmission Plan involves a total infrastructure investment of an estimated $7.3 billion and 45 transmission projects, most of which would be built in California. The Plan is based on the state’s projections that it needs to add more than 40 gigawatts (GW) of new resources over the next ten years, along with a sensitivity study projection estimating a need of 70 GW by 2032. The transition to a carbon-free electrical grid, as required by California’s clean-energy policies, has been propelling new transmission development in current and future planning cycles. The Transmission Plan will help California meet its goals.
