Welcome
to the California Public Utilities Commission (CPUC) website for the
California Environmental Quality Act (CEQA) review of LS Power Grid
California, LLC’s (LSPGC) Collinsville 500/230 Kilovolt (kV) Substation
Project (Project). LSPGC filed an application for a Certificate of
Public Convenience and Necessity (CPCN) for the Project on July 29,
2024 (Application No. A2407018). A summary of the Proposed Project is
provided in the following section.
This website provides access to public documents and information
relevant to the CEQA review process. Information about each project
review phase
will be provided in the following sections once available.
Summary of the Proposed Project
The California Independent System Operators (CAISO) 2021-2022 Transmission Plan identified the Proposed Project as a needed upgrade to the California electric grid. The Proposed Project is located in Solano, Sacramento, Alameda, and Contra Costa counties within an existing regional transmission system that provides electricity to the northern Greater Bay Area. The main components of the Proposed Project include the following:
- Constructing a new 500/230 kV substation. The proposed
Collinsville Substation would be located to the south and west of
Stratton Lane and approximately 0.75-mile northeast of the
unincorporated community of Collinsville.
- Constructing two self-supporting segments of new 500 kV conductor and structures roughly parallel along the approximately 1.2 mile interconnection route (or "loop") between the proposed LSPGC Collinsville Substation and Pacific Gas and Electric Company's (PG&E) existing Vaca Dixon-Tesla 500 kV Transmission Line. This would result in the addition of approximately 2.4 miles of new 500 kV conductor.
- Constructing a new approximately 6-mile-long,
double-circuit 230 kV transmission line to connect the proposed LSPGC
Collinsville Substation to PG&E’s existing Pittsburg Substation,
with approximately 4.5 miles of submarine cables running beneath the
Sacramento-San Joaquin River Delta waterways.
- Extending and connecting an existing PG&E 12 kV
distribution line to the proposed LSPGC Collinsville Substation.
- Constructing new telecommunications paths to the proposed
Collinsville Substation, a new microwave tower at the proposed
substation, and a new fiber optic path between existing fiber in the
City of Pittsburg and the proposed substation.
- Modifying PG&E’s existing Vaca Dixon and Tesla
Substations, including line relays and microwave towers to support the
new Collinsville Substation interconnection.
Environmental Review Process
Application and
Proponent's Environmental Assessment
LSPGC
filed Application No. A2407018 and Proponent's Environmental Assessment
(PEA) for the Proposed Project on July 29, 2024. The application is available at the CPUC Proceeding webpage. The PEA and other supporting materials are available here.
Application Review (Deficiency Reports and Data Requests)
The CPUC submitted deficiency reports and data requests to LSPGC regarding their application information. CPUC requests and LSPGC responses are
available here. LSPGC's application was deemed complete on December 11, 2024. A copy of the letter deeming their application complete is available here.
In addition, the CPUC also submitted data requests to PG&E regarding portions of the project that would be constructed by
PG&E. CPUC requests and responses are available here.
Scoping
The CPUC is soliciting scoping comments regarding environmental impacts to address in the EIR and potential project alternatives to consider. The scoping comment period is for 30 days from January 7, 2025, through February 6, 2025. The comment period closes on February 6, 2025 at 5:00pm. The NOP is available here and includes methods for submitting scoping comments. The CPUC will conduct a virtual public scoping meeting on January 21, 2025 at the following link: https://us02web.zoom.us/j/85419431269.
Environmental Impact Report
The
CPUC will prepare an Environmental Impact
Report (EIR) to evaluate the environmental effects of the Proposed
Project pursuant to CEQA. Public notices will be issued when the Draft
EIR is available
for review and comment.
