The California ISO has posted to its website a list of project sponsors for the Collinsville and Manning 500/230 kV substation projects whose project sponsor applications satisfy the information submission requirements and have been validated for the Transmission Planning Process, Phase 3 Competitive Solicitation process. Both of the lists of project sponsors are available on the 2021-2022 Transmission Planning Process webpage.

Pursuant to section 24.5.2.4 of the ISO Tariff, the ISO validated four applications for each transmission solution that satisfy the information submission requirements. The ISO will next consider whether the validated project sponsors are qualified, and then it will undertake the selection process to determine which qualified project sponsor should finance, construct, own, operate, and maintain each substation project.

More information on the 2021-2022 transmission planning process is available on the process webpage linked above.
