PSE Adds Turbines at Hopkins Ridge Wind Facility

BELLEVUE, Wash., Aug. 7, 2008--Puget Sound Energy's (PSE) Hopkins Ridge Wind Facility continues to build on the success of generating clean, renewable energy with the addition of four new wind turbines. The expansion, which brings the total number of turbines at the Dayton, Columbia County facility to 87, is another step for the utility and the region toward a sustainable energy future.

"Wind power and southeastern Washington are a great team," said Kimberly Harris, executive vice president and chief resource officer for PSE. "Hopkins Ridge is both a valuable contributor to meeting renewable energy needs, and to the local economy and tax base in Dayton and Columbia County."

Hopkins Ridge began operation in November 2005 with 83 wind turbines capable of producing 150 megawatts (MW) of electricity. With the four new 1.8 MW turbines fully operational yesterday, Aug. 6, total capacity at the facility rises to 157 MW, or the energy equivalent of that required to serve more than 40,000 homes.

In addition to the four new wind turbines, PSE also recently updated the aviation warning lights at Hopkins Ridge. An improved array of only 19 lights has replaced an initial design of 44 lights, and the lights have also been synchronized with the adjacent Marengo wind facility.

Overall, Hopkins Ridge has generated more than 1 million megawatt hours (MWh) since beginning commercial operation less than three years ago, and had a significant positive impact on the local economy. The facility employs five full-time PSE staff, with additional personnel from vendors and suppliers also on site. Along with creating jobs in the community, Hopkins Ridge has expanded the local tax base, paying more than $1.7 million in total local and county taxes since entering operation.

Production royalties to landowners with wind turbines located on their property have also benefitted the area's economy.

"Dayton is a historic community, but is also pointing the way to energy independence and a future of clean, renewable energy," said Harris. "Hopkins Ridge is a new chapter in the area's pioneer legacy, bringing a new source of economic vitality that is compatible with agriculture and the traditional family farm."

PSE is the largest utility-owner of wind energy facilities in the Northwest, and also owns and operates the Wild Horse Wind and Solar Facility, located east of Ellensburg, Kittitas County. Wild Horse entered service in December 2006 and has 127 wind turbines with the capacity to produce 229 MW of electricity with a planned expansion of an additional 26 turbines by late 2009. On July 4, 2008, it reached the 1 million MWh mark of generation since inception. Both facilities have exceeded their expected production by approximately 6 percent this year, and have demonstrated the ability to be a reliable source of year-round electric power generation and an asset to the local economy, tourism and the community.
