Duke Energy (NYSE: DUK) today announced first quarter 2010 adjusted diluted EPS of 36 cents, compared to 28 cents for first quarter 2009. Reported diluted EPS for the first quarter 2010 was 34 cents, compared to 27 cents for the same period last year.

The quarter's results were impacted by favorable weather, as temperatures were below normal in the Midwest, and February in the Carolinas was one of the coldest on record. The company also saw an increase in weather-normalized retail sales volumes, in particular in the industrial sector, as well as increased pricing.

"I'm very pleased with our first quarter performance," said James E. Rogers, chairman, president and chief executive officer. "We are seeing signs of economic stabilization, but we are mindful of the high levels of unemployment that still exist in our service territories.

"Although our first quarter was strong, we will continue to carefully manage expenses, focus on operational excellence, and work to achieve favorable regulatory and legislative policies," he added.
