Winds Topple 500 Kilovolt Line in Minnesota
LCG, Aug. 10, 2001--While they brought relief from a heat wave that sorely tested power reserves in the Upper Midwest, heavy winds and thunderstorms that rumbled through east-central Minnesota took their toll on the electric industry, knocking down a tower on a 500 kilovolt transmission line.The 500 kilovolt line, which runs from Forbes to Chisago City north of Minneapolis-St. Paul, can carry as much as 1,800 megawatts of electricity from Manitoba Power in Canada into the state. With the line down, Manitoba Power is limited to sending 300 megawatts of electricity into the Minnesota market.At the time the tower went down, the line was carrying almost all 1,800 megawatts of electricity into hot and humid Minnesota. As a result, the line's operators, Xcel Energy and Great River Energy, declared a North American Electric Reliability Council emergency through the Mid-Continent Area Power Pool.Loss of the line caused no electrical outages to customers in the area, Great River said. However, Lake Country Power Cooperative in the town of Virginia, Cooperative Light & Power at Two Harbors, and Arrowhead Electric Cooperative in Lutsen have experienced numerous distribution system outages over the last few days because of the heat.Crews from Great River and Xcel are at the site, building a road. Because of the remote location of the fallen tower, the workers have to literally build their way into the site. Consequently, the earliest completion of repairs would be Sunday. A new tower will be fabricated in Forbes and airlifted to the site by helicopter.Though no one lost power when the tower fell, trains were late. The tower fell across some railroad tracks and it took several hours for crews to remove the wreckage.
