CHARLOTTE, N.C., Feb. 1, 2013 /PRNewswire/ -- Duke Energy's (NYSE: DUK) Buck
and Riverbend steam stations, coal-fired power plants in the Charlotte area,
will retire two years earlier than scheduled, drawing to a close more than
eight decades of operations at each facility.

Both stations had been slated for retirement in April 2015 in advance of
upcoming federal environmental regulations; however, the company elected to
retire Buck Units 5 and 6 and Riverbend Units 4 through 7 on April 1, 2013.

The units have been operating infrequently in recent years and in the future
would have operated even less with the recent completion of new, more
efficient plants and low natural gas prices.

The success of the merged company's joint dispatch process that utilizes
generation across both Duke Energy Carolinas and Progress Energy Carolinas
fleets to more efficiently meet customer needs also contributed to these early

Duke Energy's joint dispatch process enables the company to more efficiently
deploy its generation fleet, which in turn produces savings for customers and
progress toward meeting the company's $687 million merger-related savings

"The investments we and our customers have made in the last 10 years allow us
to retire older stations like these and continue transitioning to cleaner
sources of electricity," said Keith Trent, executive vice president and chief
operating officer -Regulated Utilities. "These stations played pivotal roles
in the 1920s and 1930s in helping to electrify the industries and homes of the
Carolinas, and we honor all those employees who contributed their time and
talents over the years to ensure safe, reliable operations."

Buck Steam Station in Rowan County entered commercial operation in 1926 and
was Duke Power's first large-scale power plant.

Its original two units retired in 1979, and units 3 and 4 retired in May 2011.
Units 5 and 6, 128 megawatts (MW) each, began operating in 1953. Three smaller
natural gas combustion turbines at the site retired in October 2012.

The natural gas Buck Combined Cycle Station, 620 MW, began commercial
operation in November 2011. A photo of the retiring plant is available at

Riverbend Steam Station in Gaston County began operating in 1929, and units 1
and 2 retired in 1979. Unit 3 retired in 1976. Units 4 and 5, 94 MW each,
began operating in 1952, and units 6 and 7, 133 MW each, began operating in
1954. Four smaller natural gas combustion turbines at the site retired in
October 2012. A photo is available at

A total of 65 employees work at these plants. Duke Energy will make every
effort to assist them in finding opportunities within the company that match
their skills and interests, and will provide a severance for other affected

These retirements are part of Duke Energy's strategy to modernize its power
plants, which includes retiring as much as 6,800 MW of older coal and large
oil-fired units. By the end of 2013, Duke Energy will have retired more than
3,800 MW of this capacity.

In addition to building new plants, the company has invested $7.5 billion for
upgrades at other locations to enhance air quality controls since 1999. These
investments have reduced the regulated fleet's emissions of sulfur dioxide by
74 percent and nitrogen oxides by 57 percent since 2005.
