Duke Announces Major Expansion Plans at Cliffside and Buck Steam Stations

LCG, May 12, 2005--Duke Power, the regulated utility owned by Duke Energy Corp., has filed plans with the North Carolina Utilities Commission regarding the potential addition of 2,200 MW of generating capacity adjacent to three existing power plants, with total costs of more than $2.3 billion. This filing follows Duke Energy Corp.'s announcement earlier this week of its plan to acquire Cinergy Corp. for $9.1 billion.

Duke Power is proposing to build an 800 MW, coal-fired expansion at the Cliffside Steam Station for an estimated cost of $1.1 billion. The new plant could commence operations as early as 2010. Depending upon load growth, another 800 MW unit at Cliffside may be required, which would increase the total cost to about $2 billion.

An alternative to the second unit that Duke is pursuing is the development of a new nuclear power plant. Duke is a member of NuStart Energy, a consortium of major energy companies who's mission is the development of the next generation of nuclear power plants in the United States.

Duke Power's third expansion project is the addition of 600 MW of gas-fired capacity at the Buck Steam Station. The estimated cost for this plant, which is proposed to include dual (Oil and gas) fuel capability, is $350 million. Alternative sites in South Carolina are also under consideration, and Duke plans to file applications with the Public Service Commission of South Carolina in coming months. Duke Power is also seeking bids for up to 1,500 MW that would commence in 2009.
