2023-2024 Transmission Planning Process: Approved Project Sponsor for the New Humboldt 500 kV Substation, with a 500/115 kV transformer, and 500 kV line to Collinsville [HVDC operated as AC]

The California ISO has issued Business Practice Manual Proposed Revision Request 1625 that allows the ISO to take additional time to select an approved project sponsor in a competitive solicitation process under certain circumstances. The ISO is taking additional time to select an approved project sponsor to finance, construct, own, operate, and maintain the New Humboldt 500 kV Substation, with a 500/115 kV transformer, and 500 kV line to Collinsville [HVDC operated as AC] Project. This will allow the ISO to conduct additional commercial and risk management due diligence before selecting an approved project sponsor.
