Duke Energy gets permit for Citrus combined cycle natural gas project
Duke Energy Florida, a unit of Duke Energy, won approval this past fall from the Florida Public Service Commission for this project
Two existing coal-fired generators (CREC Units 1 and 2) with a total steam generator rating of 964.3 MW will be retired in conjunction with the startup of operation of the CCCP. The Citrus project is due for operation around December 2018.
The CCCP will consist of two nominal 820 MW natural gas-fueled combined cycle power blocks designated as CCCP Units 1 and 2. Each power block will consist of:
· Two natural gas-fueled nominal 270-MW Mitsubishi Power Systems 501GAC combustion turbine-electric generators with (optional) inlet chillers;
· Two heat recovery steam generators equipped with natural gas-fueled duct burners and selective catalytic reduction (SCR) reactors;
· Two 180-foot exhaust stacks; and
· A nominal 280 MW steam turbine electric generator.
Each CTG and duct burner will fire only natural gas. The maximum heat input rate of each CTG is 2,675 MMBtu/hour based on a compressor inlet air temperature of 59 degrees Fahrenheit, 60 percent relative humidity, 14.7 pounds per square inch (psi) pressure, the higher heating value of each fuel and 100 percent load. The design heat input of each duct burner located within each heat recovery steam generator is 256 MMBtu/hour.
The hours of operation of CCCP Units 1 and 2 are not limited (8,760 hours per year). The duct burners may be fired up to 16,000 hours aggregated over the four HRSGs during any calendar year.
