Project Description
The proposed project will include:
• a 2.4-m-high, 19-m-long, concrete diversion dam located at river mile 23 of South Fork Battle Creek;
• a 0.16 ha reservoir at a normal pool elevation of 1 313 m mean sea level;
• an enclosed 5 m × 8 m concrete intake structure with two 2 m × 4 m trash racks;
• a 6 m × 18 m control/fish screen structure attached to the intake;
• a 48-inch-diameter, 2.3-km-long, low-pressure pipeline and a 36-inch-diameter, 1.6-km-long, high-pressure penstock;
• a 15 m × 16 m powerhouse containing a single Pelton-type turbine and generator, with an installed capacity of 5 MW;
• a buried concrete box culvert discharging back to South Fork Battle Creek; and
• transmission facilities.
The project will bypass about 4 km of South Fork Battle Creek.
To transmit power from the generator, an underground conduit will be built to a new substation located about 152 m away.
Rugraw will connect the project to the grid by building a 19-km-long, 60 kV transmission line and a new switchyard adjacent to the Pacific Gas & Electric Company’s existing 60 kV Volta–South transmission line.
