Where Does It Go?
- The locally owned dams can generate nearly 2,000 megawatts of power at their peak
- Nearly 30 percent of the output is used to meet retail electric demand and support utility services in Chelan County.
- Another 16 percent is sold by contract to Alcoa’s Wenatchee aluminum smelter, supplying a portion of the power needs of the plant that provides important family wage jobs
- The balance is delivered throughout the Pacific Northwest to long-term power purchasers Puget Sound Energy, Avista, PacificCorp, Douglas County PUD and Portland General Electric under contracts due to expire in 2011 and 2012
- Chelan County PUD is a nonprofit corporation of the state, covered by many of the rules that govern municipal corporations. Dividends are shared with customers in the form of low rates. The District does not make a profit.
