Duke Energy (DUK 0.77%) announced today that its new 625 MW L.V. Sutton combined-cycle natural gas plant is officially open for business. The plant began operations today, pushing out power to North Carolina and South Carolina customers from its Wilmington, NC location.

This latest addition to Duke Energy's fleet comes as a $600 million replacement for a recently retired 575 MW coal-fired plant in the same location. Compared to the previous plant's 2007 figures, this natural gas alternative cuts sulphur dioxides and nitrogen oxides by over 97%, and reduces carbon dioxide emissions by 41%.

"We continue to transform our power plant fleet while maintaining our focus on generating electricity that is both reliable and affordable," said Allen Clare, Duke Energy Progress' Sutton plant manager. "Our new natural gas plant is another stride forward in meeting customer needs using highly efficient, increasingly clean energy sources."

This latest move comes as part of Duke Energy's $9 billion modernization project, which includes the retirement of almost 6,300 MW of coal-fired plants.
