GREENVILLE, S.C., Oct. 25, 2013 /PRNewswire/ --Duke Energy Carolinas on
Thursday filed an application for a Certificate of Environmental Compatibility
and Public Convenience and Necessity (CECPCN) with the Public Service
Commission of South Carolina (PSCSC) seeking approval to construct and operate
a 750-megawatt natural gas-fired combined cycle plant at the existing Lee
Steam Station in Anderson County, S.C.

Thursday's filing was in partnership with North Carolina Electric Membership
Corporation (NCEMC), which will be a minority owner of 100 megawatts of the
project if constructed.

Though no final decision to build at Lee has been made, it is prudent to
continue with the regulatory actions necessary to keep the project moving
forward.

"The energy needs of our customers are significant over the next 15 years,"
said Clark Gillespy, Duke Energy state president – South Carolina. "Our
commitment is to meet our customers' needs in a way that balances affordable,
reliable and increasingly clean electricity, and this project will help us
satisfy that need."

The utility's request is part of a comprehensive, long-term plan to add new
generation, modernize the fleet, maintain a diverse fuel portfolio, and manage
customer costs while delivering a high-quality, reliable power supply.

Natural gas-fired combined cycle plants are a good match to meet needed base
and intermediate load demands because of their high efficiency and
flexibility. Their emissions of sulfur dioxide and nitrogen oxide are very
low, and natural gas emits about half the carbon dioxide as coal.

A combined cycle unit uses combustion turbine generators, boilers and a steam
turbine generator to produce electricity.

Natural gas is burned in the combustion turbines to produce mechanical power
that is converted into electrical power by the generators. For increased
efficiency, the hot exhaust gases from the combustion turbines are used to
create steam in the boilers that spins a steam turbine-generator and creates
additional power.

The proposed project would represent a substantial long-term investment by
Duke Energy Carolinas in the Lee Steam Station site and surrounding community,
adding about 500 jobs during the height of construction.

"The Lee site is a great location for a combined cycle plant," Gillespy said.
"Duke Energy will be able to leverage existing site infrastructure to minimize
new generation project costs and impacts to the community and environment."

Construction could begin after the company receives the necessary regulatory
approvals. The new plant could begin commercial operation as early as June
2017.
