2024-2025 Transmission Planning Process: Board Approved Transmission Plan Posted

The California ISO has posted the 2024-2025 Board approved Transmission Plan to the recurring process webpage.

Each year, the ISO conducts its transmission planning process to identify potential system limitations as well as opportunities for system reinforcements that improve reliability and efficiency. The 2024-2025 transmission planning cycle involves key stakeholder activities from 2024 through early 2025.

The plan continues to reflect a new more proactive approach to transmission planning and seeks to better synchronize decisions related to power and transmission planning, interconnection queuing, and resource procurement.
