Wind power's intermittency as an energy resource but minimal contributions toward peak-capacity needs are further evidenced in operational data from three Washington and Montana wind farms. Monthly and even daily energy production vary substantially. Officials from NorthWestern Energy and Puget Sound Energy recently shared these and other wind-power experiences, including reserve requirements (challenging) and wind forecasting (improving). These tales come from the 135 MW-capacity Judith Gap wind farm in central Montana, whose entire output NorthWestern buys from developer Invenergy Wind, and PSE's 150 MW-capacity Hopkins Ridge and 229 MW-capacity Wild Horse wind projects in southeastern and central Washington, respectively. ..."The relationship between load and wind output is almost zero," the former council member told the current council. "That's a real issue for us. We continue to learn almost every day some things about wind operations on our system."

Looking east into Gilliam County and north into Washington, turbines are strung over ridgelines as far as the eye can see. And there are nowhere near enough of them. ...West Coast utilities and independent power producers are locked in a land rush to secure the best wind sites and the power they produce. Coupled with a worldwide shortage of turbines and a falling dollar, the resulting scarcity is driving up the cost of wind power, a burden electricity ratepayers will shoulder.

The United States is expected to be home to an anticipated 49,000 MW of installed wind-power capacity by 2015, making it the world's largest wind-power producer, according to a recent report. Developers are expected to invest more than $65 billion between 2007 and 2015 in wind-power facilities, researchers say.

As the Oregon Renewable Energy Act made its way through the Legislature last month, lawmakers emphasized its potential to create homegrown, clean sources of electricity. Yet, even as Gov. Ted Kulongoski signed the bill into law Wednesday, the emerging reality defied the vision of a lone state moving toward energy self-sufficiency. Oregon wind farms, expected to dominate the state's renewable power expansion, are in the sights of utilities throughout the West. Electricity buyers in California are showing interest in power generated by a wind farm under construction in Sherman County, and already California utilities have snagged power from a Washington project. And the electricity from a project under development in Oregon's Union County is headed for Idaho.

At the halfway point between the West Coast energy crisis of 2001 and the next major electricity contract renewal year of 2011, a federal power marketing agency is proposing a policy change that could affect rates in the Pacific Northwest for generations and become a national model for energy development. Northwest hydropower is one of the cheapest energy resources in the nation - about half the current market rate for electricity. The Bonneville Power Administration - which sells power in all of Washington, Oregon and Idaho and parts of California, Nevada, Utah, Wyoming and Montana - announced this summer it wants to change the way it charges utilities for its wholesale power, to keep rates low.
