Duke Energy fires up new power plants
Three new Duke Energy power plants came online at the end of 2012 to serve the utility's North Carolina customer base.
Duke Energy's Cliffside Steam Station Unit 6 went online December 30, 2012.
Estimated to cost nearly $3.65 billion, the utility says these plants represent just one aspect of Duke Energy's aggressive strategy to make the transition to cleaner generation sources. In addition to this investment, Duke has invested almost $6 billion since 2007 in new plants and another $7.5 billion for upgrades to existing plants in order to reduce emissions. Duke has also retired 6,800 MW of older coal capacity.
The 825 MW Cliffside Steam Station Unit 6 employs a combination of air quality controls to remove 99 percent of sulfur dioxide, 90 percent of nitrogen oxide and 90 percent of mercury. The unit burns a wide range of coals with superior emissions removal, allowing Duke to purchase cost-effective coals.
The 920 MW H.F. Lee Plant utilizes a highly efficient natural gas combined-cycle design. Progress Energy Carolinas retired three older coal units totaling 382 MW and four combustion turbines at the H.F. Lee Plant in the fall of 2012.
The Dan River Combined Cycle Station provides 620 MW of natural gas-fueled generation and provides more than twice the 276 MW of coal capacity Duke Energy retired there in spring 2012.
Since 2005, Duke has reduced its regulated fleet's sulfur dioxide emissions by 74 percent and nitrogen oxide emissions by 57 percent.
