Project Description

The Helms Pumped Storage Project (Project) is a pumped storage project that transfers water to and from Courtright Lake and Lake Wishon, and is located approximately 55 miles northeast of the City of Fresno. The Project includes Courtright Intake-Discharge Structure (89 feet wide by 58.5 feet high) and Wishon Intake-Discharge Structure (78 feet wide by 51 feet high). In pumping mode, water is diverted from Lake Wishon and pumped into Courtright Lake.  In generating mode, water is diverted from Courtright Lake via a series of tunnels and penstocks to the Helms Powerhouse, which has a generating capacity of 1,080-megawatts, and discharged into Lake Wishon.  Releases from Courtright Lake and Lake Wishon are managed as part of the Haas-Kings Hydroelectric Project (FERC Project No. 1988).
