Duke Energy announced February 1 that it will retire two of its coal-fired power plants in North Carolina on April 1, 2015, over two years earlier than previously scheduled. The retirements are part of the company’s plan to modernize its facilities and retire up to 6,800 MW of its older coal- and oil-fired units, and were chosen because they have been infrequently operated, the utility has recently built more efficient plans, and natural gas prices are low.
