A Terrific Two (Million)!

PSE’s Lower Snake River Wind Facility Passes the 2,000,000 Mark for Generated Megawatt-Hours

BELLEVUE, Wash. (June 27, 2014) – More than 27 months after becoming operational, Puget Sound Energy’s Lower Snake River Wind Facility near Pomeroy — one of Washington’s newest and largest wind farms — hit a milestone this morning: The clean energy generated by the 149 turbines at the site passed the two-million megawatt-hours (MWh) mark.

The turbines at Lower Snake River pump out enough renewable electricity to power roughly 100,000 homes.  And they offer an economic jolt to the southeastern part of the state.

  • Lower Snake River started commercial operations on February 29, 2012.
  • On an average day, the turbines generate 3,000-4,000 MWh. 
  • The single-day generation record is 8,036 MWh set on April 20, 2013.
  • The turbines are located in the wind-blown hills of Garfield County, an agricultural area to the northeast of Walla Walla. There are no stop lights in the entire county.
  • Wind power and agriculture work well together. The site covers 21,610 acres, which is nearly all private, locally-owned crop and range lands.  The turbines, support structures and access roads cover less than one percent of that total acreage.

On a large scale, the production of power over time is measured in megawatt-hours of energy. A megawatt-hour is 1,000 kilowatt-hours (kWh). A kilowatt-hour is commonly used to calculate residential electricity bills.

An average residential PSE customer uses about 11,000 kWh every year. Other examples:  new, energy-efficient refrigerators use about 300-400 kWh per year, and a kilowatt-hour would power a 100-watt light bulb for 10 hours.

The wind turbines at Lower Snake River are near PSE’s Hopkins Ridge Wind Facility, just outside the town of Dayton in Columbia County. The 87 turbines there began operating in November 2005, and so far, they have generated more than 3.5 million megawatt-hours.
