CAISO Allocates $1.3 Billion Less for Transmission Development Focusing on Reliability for 2024-2025
The California Independent System Operator (CAISO) has reduced its transmission development budget by $1.3 billion for the 2024-2025 plan, shifting focus to reliability-driven projects. The peak demand growth rate increased from 0.99% to 1.53%, particularly in the Greater Bay area. CAISO's plan enables the connection of significant renewable energy resources and compliance with Federal Energy Regulatory Commission mandates, while addressing challenges from electrification and data center load growth.

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.
