Generating fleet meets all-time winter peak demand

Our fleet of coal, natural gas and renewable power plants was severely tested last week as demand soared during the extreme cold weather. At its peak on Jan. 7, the Midcontinent Independent System Operator (MISO) called on our plants to deliver nearly 6,300 megawatts (MW) to the market. This eclipsed the previous winter peak of just more than 5,900 MW set Dec. 12, 2013. Prior to this winter, the highest winter output was approximately 5,750 MW, set in December 2009.

Our power plants operate within the MISO market, which includes 15 U.S. states and one Canadian province, covering and managing one of the largest wholesale electricity markets in North America. MISO dispatches our units among hundreds of other generating units within the MISO footprint to meet electricity demand.

Despite the challenging conditions, our power plants met the demand and kept the power and steam flowing for our customers.
