CAISO has reduced its transmission development budget by $1.3 billion for its 2024-2025 plan, prioritizing reliability-driven projects over policy-driven ones. The peak demand growth rate increased from 0.99% to 1.53%, with a notable rise in the Greater Bay area.

The plan allows for 30 GW of solar, 7 GW of onshore wind, and 4.5 GW of offshore wind imports, while also complying with FERC Order No.1920. CAISO will transition to a biennial planning cycle starting in 2030 and plans to launch the Extended Day-Ahead Market with PacifiCorp and PGE. The 2024-2025 plan includes 28 reliability-driven projects, a rise from 19, and decreases overall projected spending from $6.1 billion to $4.8 billion.
