American Governor Awarded Modernization Project at PG&E’s Helms Pumped Storage Facility

Ivyland, PA – Once again AGC has demonstrated its dominance and expertise in the hydro governor and plant controls market by being awarded a contract by Pacific Gas & Electric (PG&E) for the first of three governor modernizations at its Helms Pumped Storage Facility in beautiful Fresno County, California, on the edges of the Sierra National Forest.

The impressive Helms Pumped Storage Facility for PG&E involves two different lakes at different elevations in the Sierra National Forest. Water is pumped to the upper lake during periods of low power demand and used to generate power during peak power demand periods. The powerhouse itself is imbedded more than 1,000 feet into the side of a massive granite mountain. Helms, PG&E’s single largest hydro powerplant, has three 404-megawatt units and currently powers about 850,000 homes in California.

AGC will be responsible for providing equipment, engineering, and site services for the modernization of the hydroelectric governor systems. The evaluation process for PG&E included consideration of prospective contractor’s past experience controlling pump/turbine units, their technical capability, and their past performance references for governor upgrades. Competitive pricing was also important.
