Cash Creek Generation LLC proposes to construct a natural gas-fired combined-cycle power plant on Kentucky State Highway 1078 in Henderson County, Kentucky.
The Kentucky Division for Air Quality on Dec. 24 posted to its website a draft air permit. The project will be comprised of two combined cycle combustion turbines (CTs), each equipped with a heat recovery steam generator (HRSG) and duct firing. Each CT will each drive an electric generator and the two HRSGs, in combination, will drive a third electric generator with steam. The duct firing will produce additional steam for electric generation.
The emissions from the CTs and duct burners will be vented through the HRSG stacks. Each stack will be 199 feet tall. The only fuel permitted to be used will be pipeline quality natural gas with a sulfur content of less than or equal to 1.0 grains/100 dscf.
Said a DAQ summary: “The two CTs and associated HRSGs will produce electrical power for sale. The units are not lean premix or diffusion flame, and do not use water or steam injection for control of nitrogen oxides (NOx). The HRSGs utilize the hot flue gas from the combustion of natural gas in the CTs to produce steam to power a single steam turbine for additional electrical power output. Each HRSG is also equipped with a duct burner.”
The power output would be about 231.9 MW from each turbine at 0 degrees Fahrenheit (which does not include power from the steam turbine generator). The maximum gross output for the project would be 849 MW at 0 degrees F.
Notable is that Cash Creek once planned a coal gasification project in this region, but the permit documents say about the allowed fuel for this project: “Pipeline Quality Natural gas only.”
