Golden Hills
The Golden Hills Wind Farm is located in the Diablo Range between Livermore and Tracy at the Altamont Pass in Alameda County. It is home to one of the oldest wind farms in the U.S. and the largest concentration of wind turbines in the world. The turbines in the Altamont Pass area were first constructed in 1981 in response to favorable federal and state legislation that resulted from the energy price increases of the 1970s.
The Golden Hills Wind Farm project removed hundreds of the existing aging turbines first installed in the 1980’s and replaced them with 48 turbines, each producing 1.79 megawatts of power. These 48 turbines are capable of generating enough electricity to power approximately 25,500 homes. The project site is about 6 square miles, and over 18 miles of access road was constructed with 1.6 million cubic yards of grading.
Golden Hills North
The Golden Hills North wind project is a complete repowering of one of the oldest wind facilities in North America. The redevelopment removed 283 30-year-old wind turbines and
replaced them with just 20 2.3 megawatt GE turbines, capable of generating even more power with twice the efficiency of the previous wind project. Golden Hills North will have a
generating capacity of 46 MW, enough to power more than 13,500 homes.
As part of a 20-year power purchase agreement, the project will serve customers of Sonoma Clean Power with clean, renewable energy. “Repowered wind facilities
carry multiple benefits,” offered Geof Syphers, Sonoma Clean Power’s CEO. “One modern wind turbine replaces 21 of the old-style turbines, producing more energy.”
dk Engineering completed a topographic survey, boundary survey, grading plans, erosion control plans, stormwater control plans, and construction staking services.
