DENVER – A company that supplies power to rural electric cooperatives in four Western states announced Monday that it will buy electricity from a new wind farm on Colorado’s Eastern Plains.

The wind farm – to be built near Burlington – will supply enough electricity to power up to 14,000 households served by Tri-State Generation and Transmission Association Inc. A subsidiary of Duke Energy, one of the nation’s largest power generators, will build the farm and then sell the power to Tri-State for 20 years.

It’s the first large wind power deal for Tri-State, based in suburban Denver, which supplies power to 44 electric cooperatives in Colorado, Nebraska, New Mexico and Wyoming. The co-ops provide power to about one million people who live on farms and ranches as well as towns and suburban neighborhoods.

The 51-megawatt wind farm, expected to be completed by the end of 2010, will have 34 turbines spread across 6,000 acres. Tri-State said about 150 people will be needed to build it and four to eight full-time technicians will maintain it.

Terms of the deal between the two companies weren’t disclosed, although Wouter T. Van Kempen, president of Charlotte, N.C.-based Duke Energy Generation Services, said the construction costs were “north of $100 million.”

Tri-State, a partner in a controversial plan to build a new coal-fired power plant in Kansas, has come under criticism for not moving quickly enough to expand its supply of renewable energy. Colorado regulators are also considering increasing oversight over Tri-State’s plans for future power generation.

Currently only 1 percent of Tri-State’s power comes from wind and solar. Power from the new wind farm and a solar plant planned for Cimarron, N.M. will take it to 3 percent. By contrast, the state’s largest utility, Minneapolis-based Xcel Energy, gets 10 percent of its power from renewable resources. It started buying wind energy a decade ago using voluntary contributions from customers.

A law passed by voters and later toughened by lawmakers will require Tri-State to get 10 percent of its energy from renewable sources by 2010. Xcel will need to increase its portfolio to 20 percent.

Tri-State executive vice president and general manager Ken Anderson the company is also looking at adding geothermal sources of energy and producing solar energy on its existing coal plants. He said the company has moved carefully into renewable energy to avoid making expensive mistakes that would have to be paid for by its member co-ops.

“A little bit of patience by everyone is appreciated when you’re talking about making investments like this,” Anderson said after signing the contract with Duke at a ceremony at the state Capitol. Gov. Bill Ritter, who has promoted renewable energy in the state, stood next to the table at the base of the West Steps.

Colorado already has 12 wind farms, most of which produce power for Xcel. Together, existing turbines produce enough power for 400,000 homes, said Craig Cox, executive director of Colorado-based Interwest Energy Alliance, a trade and advocacy group. The group says there are over 30 wind farms of various sizes in Arizona, Wyoming, New Mexico and Utah as well as Colorado.

Cox said Tri-State serves some of windiest states and has the opportunity to sell its wind energy in both the eastern and western sides of the national grid.

“It’s good to see that they’re starting to look at their great wind potential,” he said.

Anderson said tax breaks included in the federal stimulus package reduced the cost to Duke and helped make it easier for Tri-State to move ahead with the wind farm now. The project will also save money by using Tri-State’s existing transmission lines to move the power to customers.

Duke Energy also announced Monday that it was closing on the purchase of its first commercial wind farm in the East, the 70-megawatt North Allegheny Windpower Project about 95 miles east of Pittsburgh. It said the farm will produce enough energy to power 18,000 homes.

In the West, Duke also owns two wind farms in Cheyenne, Wyo. and one near Casper.
