The Monticello Nuclear Generating Station, located 40 miles northwest of the Twin Cities, generates approximately 10 percent of the electricity used by Xcel Energy’s customers in the Upper Midwest. The plant helps Xcel Energy avoid producing hundreds of millions of tons of greenhouse gases, including 13 million tons of carbon, which is the equivalent of removing two million cars from the road each year.
Collins successfully completed the Extended Power Uprate project for Xcel Energy. The scope included increasing capacity of the plant by 12 percent and extending the licensing for 25 years.
