Portal Hydroelectric Project
Federal Energy Regulatory Commission (FERC) Project No. 2174
Applicant: Southern California Edison (SCE)
FERC License Expiration Date: March 31, 2005
Water Quality Certification Status: Final Issued - May 31, 2019
Water Body: Camp 61 Creek.
FERC Licensing Processes: Traditional Licensing Process (TLP)
The Portal Hydroelectric Project (Portal Project) is one of seven FERC-licensed projects that are part of a hydroelectric system owned and operated by Southern California Edison (SCE), and referred to collectively as the Big Creek Hydroelectric System. The Portal Project is located on Camp 61 Creek in Fresno County, and occupies approximately 77 acres of national forest land administered by the United States Forest Service. Major Portal Project facilities include the Portal Dam and Forebay, the Portal Powerhouse, the Adit 2 Conduit; and approximately 2.5 miles of transmission line. The Adit 2 Conduit conveys water between the Portal Forebay and Ward Tunnel, the latter of which conveys water from the Portal Forebay, Lake Thomas A. Edison, and Florence Lake reservoirs to the Portal Powerhouse. The sole function of the Portal Forebay is to equilibrate the hydraulic head in the downstream portion of Ward Tunnel to facilitate power generation at Portal Powerhouse. The Portal Project has an authorized generation capacity of 10.8 megawatts (MW).
SCE proposes to continue operation of the Portal Project without major modification, but has collaborated with involved stakeholders and resource and regulatory agency staff throughout the relicensing process to develop a range of environmental protection, mitigation, and enhancement measures for the Portal Project. These measures are described in SCE’s license application and Big Creek Alternative Licensing Process (ALP) Hydroelectric Projects Settlement Agreement (Settlement Agreement). The Settlement Agreement establishes certain obligations for the protection, mitigation, and enhancement of environmental resources affected by the Portal Project when a new hydropower license is issued by FERC. SCE has requested that FERC and the State Water Board incorporate some provisions of the Settlement Agreement into the new Portal Project license and water quality certification.
