Xcel to Curtail SOx from Coal Plants

LCG, Dec. 30, 2002--Emissions of sulfur dioxide (SO2) will be cut starting in January under a program initiated by Xcel Energy and covering three coal-burning power plants it owns in the Denver area.

The investment of $211 million needed will come from rate increases extending over 15 years. A typical residential customer will pay 91 cents as a surcharge on his or her monthly bill, while business customers will pay an average of an additonal $1.85 for the program. Xcel, based in Minneapolis, is not required to make the improvements to its plants, but was allowed to do so with the approval of the Colorado state legislature in 1997.

Emissions reductions will be equivalent to a 70 percent reduction compared to uncontrolled releases from the plants, which represent a total of 1,100 megawatts of capacity. Additionally, two units at a plant will be shut down. Xcel said it plans to make even more significant reductions in Minneapolis if the state gives it the necessary approval for changes in rates.
