Lost Creek 1 and Lost Creek 2
The Lost Creek projects are located on Lost Creek at the
mouth of Lost Creek
Canyon in eastern Shasta County, California.
The Lost Creek 1 project consists of a 1.1 MW capacity powerhouse at the end
of a 2,750 foot long steel penstock. Hydraulic capacity is 65 cfs and the
gross head is 222 feet. The water is diverted into the penstock at an intake
structure at the edge of Lost Creek. The intake structure includes a
self-cleaning fish screen. The turbine-generator is a horizontal shaft
Francis style turbine with a synchronous generator. Transmission to a third
party substation is via a 3.4 mile long 12kV transmission line. Operation
began on December 5, 1989.
The Lost Creek 2 project is located on Lost Creek downstream of the Lost
Creek 1 project. The project consists of a 450 kW capacity powerhouse at the
end of a 2,200 foot long steel penstock. Hydraulic capacity is 80 cfs and the
gross head is 85 feet. A concrete weir diverts project water to the intake
structure. The intake structure includes a fish screen and automatic screen
cleaner. The turbine-generator is a horizontal shaft Francis style turbine
with an induction generator. Transmission to a third party substation is via
the same 12kV transmission line that Lost Creek 1 uses. Commercial operation
began on July 29, 1989.
Power is sold to Pacific Gas & Electric Company under contract through 2020.
The owner is Snow Mountain Hydro LLC, in which Ida-West Energy Company owns,
indirectly, a 50 percent interest. Operation and maintenance is performed by
Ida-West Operating Services, Inc.
