Sonoma Clean Power broke ground today on a project that will update an existing wind power facility and bring more wind power in-state.

The Golden Hills North Wind Facility, in the western central valley community of Tracy, will remove 283 30-year-old wind turbines and replace them with 20 2.3-megawatt GE turbines, capable of generating more power with twice the efficiency of the previous wind project.

Sonoma Clean Power is a a community choice aggregation, or CCA, organization, created under state policy that allow local governments to pool their electricity load so they can provide alternative energy sources. Currently, most wind energy in SCP”s portfolio comes from Oregon. The Golden Hills facility is forecasted to cover 6 percent of SCP’s load starting in 2018. The contract term is 20 years from full commercial operation date.

“Repowered wind facilities carry multiple benefits,” said Geof Syphers, SCP’s CEO. “One modern wind turbine replaces 21 of the old-style turbines, producing more energy. This is low-cost, clean electricity that will serve our customers of Sonoma and Mendocino counties.”

SCP is partnering with wholesale electric power generator NextEra Energy Resources. An affiliate of that company owns and will operate the wind project.

The wind project will have a generating capacity of 46 megawatts, enough to power more than 13,500 homes.

SCP’s announcement stated the project will also create hundreds of union jobs during the construction phase, beginning this month, and will provide full-time employment opportunities once the project is operational at the end of 2017. The project will provide more than $10 million in property tax benefits over its projected 30-year operational life.

Fewer wind turbines will also significantly reduces bird strikes.
