Idaho Power Eyes Wind Generation Options

 

Sep 13 - Idaho Business Review, The

Idaho Power's biennial plan for energy sourcing includes wind power for the first time.

But wind's lack of predictability, and scant transmission facilities where winds blow the strongest, make large-scale development a tall order.

Every two years, the company updates its Integrated Resource Plan for providing power over the next decade. The 2004 version calls for more than 1,000 megawatts of new electricity over the period, including 350 MW of wind power.

Idaho Power plans to request proposals for 200 MW of wind power this fall, spokesman Dennis Lopez said, if the state Public Utilities Commission approves the Integrated Resource Plan.

If you have a megawatt of wind online, you can conserve water during that time, he said, referring to hydroelectric plants. So you can balance your portfolio with wind, and that's exactly what we intend to do.

While Idaho Power has no wind-power sources of its own, the company's donation-funded Green Power Program buys wind-generated power to direct into the Idaho Power grid.

The company buys about 1 MW a year from the Stateline wind farm near Walla Walla, in eastern Washington, plus smaller amounts from wind turbine operations between Boise and Mountain Home, and in Montana.

Wind-generated power can supplement the grid and enable power from other sources to be conserved. But wind power can't be stored on a large scale, and thus can't be tapped on demand to send from one place to another on the grid.

One of the downsides is that it's not a 'dispatchable' resource, Lopez said. It's not storable, and it's also not a load-following resource like hydro where you can open up the gates and run more water through.

Nevertheless, it's important that we look at it for part of our generation mix, he said.

The problem is, where there is good wind, there is not immediate transmission access, Lopez said.

Wind power generally sells for less per unit than hydropower and other sources because it is less predictable, Idaho Public Utilities Commission spokesman Gene Fadness said.
