Rocky Mountain Power has three 99-megawatt wind projects going through the permitting process in Wyoming, Hymas said. The Glenrock and Rolling Hills projects are on the site of a former PacifiCorp coal mine that was determined to be no longer economical and then reclaimed.

"The third is the Seven Mile Hill wind project, and that one is planned in Carbon County, Wyo., near Medicine Bow," he said. Each of the three wind farms can generate 99 megawatts of power using 66 turbines. They are due to be completed by the end of this year.

The huge Foote Creek I wind farm near Arlington, Wyo., boasts nearly 400 turbines capable of generating 600 kilowatts of electricity apiece. PacifiCorp has an interest in the Eugene, Ore., Water and Electric Board facility. According to a PacifiCorp Web site, the company owns 32.6 megawatts of the output.

Also near Arlington, Wyo., is the Rock River I wind project with 50 turbines, each capable of 1 megawatt of power production. "In 2001, PacifiCorp agreed to purchase all of Rock River I's output for the next 20 years," the site adds.

Another project from which PacifiCorp will be buying electricity is the wind farm being built at the mouth of Spanish Fork Canyon by Wasatch Wind Inc., based in Heber City. "That will be the first commercial wind project constructed in Utah," Hymas said.

Eskelsen said the project will feature eight turbines, each capable of generating around 2 megawatts. Its power will be sold to Rocky Mountain Power. Generation should come on line this summer, he said.

A Newton, Mass., company, UPC Wind, announced in December that it had signed an agreement to supply the city of Los Angeles 185 megawatts of electricity from a wind farm to be built in Utah's Milford Wind Corridor. The wind farm, with 80 generators capable of producing 2.5 megawatts each, will be on Bureau of Land Management and private land in Millard and Beaver counties, according to the company.

Tasco Engineering, based in Lehi, is developing a wind project on the Stockton Bar, an immense sandbar left in Tooele County by ancient Lake Bonneville. "The project is cited for 70 megawatts," said Gary Tassainer, the company's president.

"It looks like they will start construction in fall 2008," he said. Electricity generated by Tooele County's wind would go to Salt Lake City through PacifiCorp.

Mark Kot, county planner for Sweetwater County, Wyo., said Tasco is developing a project whose first 36 wind turbines were approved by the county commission on Oct. 2. They would be built on White Mountain, west of Rock Springs, and the power would go onto the western power grid through PacifiCorp.

"That project could go to about 100 turbines over the next five years," Tassainer commented.
