Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of the proposed LS Power Grid California, LLC. (LSPGC) Round Mountain 500 kV Area Dynamic Reactive Support Project (Project). An application for this project was submitted to the CPUC on April 6, 2022 (Application A.22-04-004). This site provides access to public documents and information relevant to the CEQA review process.


LSPGC, in its CPUC application (A.22-04-004), filed on April 6, 2022, requests a permit to construct a Static Synchronous Compensator (STATCOM) Substation (the Fern Road Substation), which would include an approximately +/-529 million volt-amperes, reactive (MVAR) dynamic reactive support facility to include a minimum of two equally sized STATCOM units. The STATCOM units would be located within the new Fern Road Substation and would be independently connected (e.g., looped-in) to Pacific Gas and Electric Company’s (PG&E) regional electric transmission system via the Round Mountain – Table Mountain #1 and #2 500 kV transmission lines that are located adjacent to the Project site.

The Project (see Location Map) would be located in east of Fern Road and east of the existing PG&E transmission right-of-way (ROW), approximately 1.6 miles northwest of the unincorporated community of Whitmore and approximately 9.3 miles north of State Highway 44 in unincorporated southern Shasta County. The Project would include interconnection to PG&E’s electrical transmission system via Round Mountain – Table Mountain #1 and #2 500 kV transmission lines, and upgrades to the existing PG&E Round Mountain and Table Mountain substations. The Project work would take place upon lands owned by LSPGC or within PG&E easements. The application includes the Proponent’s Environmental Assessment (PEA) prepared pursuant to Rule 2.4 of the CPUC's Rules of Practice and Procedure.

The purpose of the Project is to ensure reliability of the California Independent System Operator Corporation (CAISO) controlled grid. The need for the Project was determined as part of the CAISO Transmission Planning Process. The CAISO 2018-2019 Transmission Plan determined that a dynamic reactive support facility was needed near the Round Mountain Substation to mitigate excessive high voltage and dynamic stability issues.

Current Project Status

The CPUC voted to approve the Project and close the formal proceeding for the PTC application on January 11, 2024. The CPUC’s Decision 24-01-011 was issued on January 11, 2024. On January 23, 2024, LSPGC submitted a Notice to Proceed Request for construction of the Project that was approved by CPUC on January 25, 2024 (see below). Approval of the NTP Request included all project components. Construction began in February of 2024 and is anticipated to be completed in November of 2025.

Construction Progress and Mitigation Monitoring Reporting, Compliance, and Reporting Program

A Mitigation Monitoring, Compliance, and Reporting Program (MMCRP) was approved by the CPUC to ensure compliance with applicant proposed measures and CPUC mitigation measures identified in the Final IS/MND and adopted in Decision 24-01-011. The CPUC, as the lead agency, is responsible for ensuring that the Applicant Proposed Measures, mitigation measures, as well as plans reviewed and approved by other agencies, are implemented throughout the construction phase of the Project. As construction progresses, the Project documents related to mitigation monitoring will be made available for public review. 

Mitigation Monitoring, Compliance and Reporting Program (MMCRP)

Mitigation Plans

The plans prepared pursuant to the approved MMCRP were submitted by the Applicant and are available below:

  • Traffic Control Plan
  • Construction Fire Prevention Plan
  • Spill Prevention Control and Countermeasure Plan
  • Stormwater Pollution Prevention Plan and SWPPP Appendix
  • Hazardous Materials Management Plan
  • Geotechnical Engineering Report
  • Paleontological Resources Monitoring and Mitigation Plan
  • Restoration Plan
  • Notice to Proceed

    LSPGC must obtain a Notice to Proceed (NTP) from the CPUC prior to initiating construction activities in accordance with the procedures outlined in the MMCRP. The NTP request and approval are provided in the table below:  

      Description Date Submitted Approval
    NTP Request Request of the full Project approval for the construction of the Fern Road Substation containing two static synchronous compensator (STATCOM) units and ancillary components adjacent and independently connected to Pacific Gas and Electric Company’s (PG&E) regional electric transmission system via the Round Mountain – Table Mountain #1 and #2 500 kV transmission lines. 1/23/2024 CPUC Approval 1/25/2024

    Minor Project Refinements

    Minor project refinements (MPRs) are strictly limited to changes that will not trigger an additional permit requirement (except local government ministerial permits and associated requirements), do not substantially increase the severity of a previously identified significant impact based on criteria used in the IS/MND, create a new significant impact, are located within the geographic boundary of the study area of the IS/MND, and that do not conflict with any mitigation measure or applicable law or policy. The NTP Request includes one minor Project refinement to provide clarification of its understanding of IS/MND APM AES-2 regarding the use of equipment components with reflective finishes. This minor refinement was approved as part of the NTP. 

      Date Submitted Approval Date
    MPR-1 MPR-1 was approved as part of the NTP CPUC Approval 1/25/2024
    MPR-2 February 6, 2024 CPUC Approval 2/14/24

    Quarterly Reports

    Consistent with the MMCRP provided above, the Applicant (LS Power) must provide the CPUC with written quarterly reports of the Project to include progress of construction, resulting impacts, mitigation implemented and all other noteworthy elements of the project. Quarterly reports are required as long as the mitigation measures are applicable. Quarterly compliance reports submitted by LS Power will be provided below, once available. 

    Environmental Review

    The CPUC has prepared an Initial Study/Mitigated Negative Declaration (IS/MND) to evaluate the environmental effects of the Round Mountain 500kV Dynamic Reactive Support Project. The table below shows milestones and dates associated with the environmental review process..
