A CCGT combines two natural gas-fired turbines and a steam turbine to maximize efficiency. IPL will retire six existing units at the facility and retire or refuel four at its Harding Street Generating Station. Comprising 23 gas turbines and seven steam turbines, the installed power generation capacity of the DUBAL Power Plant is 2,350 MW (at 30˚C). Typically, power plant efficiencies (LHV basis) can be taken as follows for estimation purpose,. The modern combined cycle gas turbine technology ensures high efficiency, low fuel consumption and fewer (by around 30 per cent) pollutant emissions versus conventional steam power plants. Combined Cycle Gas/Steam Turbine 40-45%. Natural gas will be used The Nikiski Combined Cycle Conversion Project is the cornerstone of HEA's plan for producing its own power when the existing power supply contract with Chugach Electric expires at the end of 2013, spokesman Joe Gallagher explained. Since waste heat is being used to produce steam, the Nikiski HEA plant will see an increase from its original output of 40 megawatts to 60 megawatts without using any additional natural gas. Simple Cycle Gas Turbine 26-28%. The $631 million combined-cycle gas turbine (CCGT) power station will go in Morgan County at IPL's Eagle Valley Generating Station, about five miles north of Martinsville. The gas turbines are fuelled primarily by natural gas and, thanks to the cogeneration and combined cycle configuration of the utility, approximately 36.8% of the power generated at DUBAL is fuel-free. Combined-cycle power generation systems combine gas turbines and steam turbines to achieve very high fuel efficiency and reduced CO2 emissions as compared to conventional thermal power plants.
