Dry River Likely to Reduce Colorado Plant Output

LCG, Sep. 13, 2002--The Comanche Generating Station of Pueblo, Colo., is preparing to curtail its output as owner Xcel Energy adjusts to dry conditions in the St. Charles River, the source of the plant's cooling water.

The plant manager, Mike Hernandez, told the Pueblo Chieftain that the ultimate reduction in usage of cooling water is targeted at 30 percent, but that the current reduction of less than 10 percent has not affected the output provided to customers. Aquila purchases power from the plant, as does Rocky Mountain Steel Mills.

The Victoria Avenue station, which obtains cooling water from the Arkansas River, is also drawn upon by Aquila. Victoria Avenue has had to reduce its production due to low levels in the Arkansas.

It may not be possible for Aquila and Rocky Mountain Steel Mills to continue to buy or sell the same amount of power in the area they had previously, as transmission lines are not currently able to transmit enough power to make up the difference. The 30 percent reduction is scheduled for October, as Xcel spends $420,000 on a project to recycle water at the plant.
