Coal Plants in Minnesota to Be Upgraded

LCG, Dec. 11, 2003--Three coal-fired power plants in Minnesota will be shut down by the utility Xcel Energy Inc. while emission-control equipment is installed and the capacity of the units is increased, based on what the company said is an intention to stay ahead of increasingly stringent environmental regulations.

The work plans developed from discussions with the Minnesota Department of Commerce, the Minnesota Pollution Control Agency, environmental groups, and the office of the state Attorney General. The projects, which cost over $988 million, will need to receive the approval of the Minnesota Public Utilities Commission, which may issue its decision by next week.

The plants in question include the 564-megawatt King plant, built in 1968 outside the Minneapolis-St. Paul area, the High Bridge plant, based in St. Paul, and the Riverside plant, in Minneapolis. The High Bridge plant, built in 1923, will undergo conversion from burning coal to burning gas, and have its capacity increased from 271 megawatts to 515 megawatts. The Riverside plant, built in 1911, will also be converted to natural gas from coal, and gain 56 megawatts of capacity, for a total of 439 megawatts.

The costs of the upgrades will be spread over a thirty-year period and added to customers' bills. The plants would be shut down and returned to service one by one, with King having a scheduled completion date of 2007. High Bridge and Riverside respectively would follow in each of the next two years. In each case, the work would begin in September, and operations would start again by the following May.
