WISCONSINREPORT.COM (08/18/08) - The Weston 4 power plant, of which Dairyland Power Cooperative has a 30 percent ownership interest, was officially dedicated today. Weston 4 has been named Power Plant of the Year by Power Magazine. Dairyland President and CEO Bill Berg joined Wisconsin Public Service Corporation President Charlie Schrock, Public Service Commission of Wisconsin Chairperson Eric Callisto and officials in a ceremonial ribbon cutting at the plant’s dedication ceremony.

The newly constructed 525 MW (nominal rating) power plant became commercially operational on June 30, 2008. It uses clean coal technology, a high efficiency boiler, low sulfur coal as fuel and features sophisticated emission controls to minimize environmental impacts.

Wisconsin Public Service Corp., the majority owner, constructed and operates the plant which is located near Wausau, Wis.

Weston 4’s state-of-the-art design led it to be recently designated as Power Magazine’s 2008 Plant of the Year.

“We are proud to be a partner in Weston 4, which is supplying our members with the clean, reliable electricity they need,” said Bill Berg, Dairyland President and CEO.

Construction on the $774 million project began in October 2004. The massive project required nearly 1,000 construction workers, who built the plant safely and on-schedule.

With headquarters in La Crosse, Wis., Dairyland provides wholesale electricity to 25 member distribution cooperatives and 17 municipal utilities.

A Touchstone Energy Cooperative, Dairyland’s service area encompasses 62 counties in four states (Wisconsin, Minnesota, Iowa and Illinois).

Dairyland’s generation resources include coal, natural gas, hydro, wind, landfill gas and animal waste. For more information, please visit www.dairynet.com.
