Rowe told investors today that Exelon is well on track to meet or beat its 2001 earnings target of $4.50 per share. Rowe made the announcement during a presentation at the Deutsche Banc Alex. Brown Power Conference in New York. Rowe attributes the success to the smooth transition of the merger of Unicom and PECO Energy that formed Exelon Corporation and value-creating opportunities in the first quarter that were better than the company anticipated. "These opportunities were fueled by high gas prices that persisted through early spring in our two principal markets, but they also arose from our PowerTeam's increasing knowledge of how to move power around the high demand markets within our reach," Rowe says. "Also, the ComEd distribution system is in its best shape in recent years, and although we expect peak demand of 21,850 megawatts this summer, we have locked enough power to meet the demand of 23,600 megawatts. Exelon is committed to protecting our customers from the reliability problems currently plaguing California." Asked how an excess supply of generation would affect Exelon's earnings and profitability, Rowe cited the resilience of and earnings protection afforded by Exelon's low cost of nuclear production (less than 2.2 cents/kilowatthour), the expertise and market reach of PowerTeam and the heavy demand generated from ComEd and PECO's combined customer base of 5 million. Exelon will report its second quarter earnings on July 24, 2001 before the market opens.
