The California ISO identified three regional transmission solutions that are eligible for competitive solicitation in the Board Approved 2022-2023 Transmission Plan. The ISO posted descriptions of transmission solutions eligible for competitive solicitation in Appendix I of the Board Approved 2022-2023 Transmission Plan in May 2023 and posted revisions to these descriptions on Aug. 3, 2023. Subsequent to the posting, the ISO determined that additional changes were necessary. The revised project descriptions can be found in Appendix I on the transmission planning process webpage.
Details on Phase 3 of the transmission planning process are available in ISO Tariff Section 24.
