Puget Sound Energy has commenced commercial operations on the 343MW Lower Snake River wind facility (phase I) in Washington, US.

The wind farm provides more renewable, emissions-free power to Puget Sound Energy’s 1.1 million electric customers.

The new facility’s 149 wind turbines will generate enough electricity, on average, to power about 100,000 homes.

PSE began construction of the Lower Snake River facility in May 2010 with the help of lead contractor Renewable Energy Systems Americas, wind-turbine manufacturer Siemens Energy, and a variety of subcontractors.

PSE also partnered with RES on the construction of the utility’s Hopkins Ridge and Wild Horse wind farms.

The Lower Snake River wind farm spans more than 21,600 acres in western Garfield County.

The wind facility’s power output ties into the Northwest electric grid at the Bonneville Power Administration’s newly completed Central Ferry substation, constructed along the wind farm’s northern boundary.
