The 24 pages that link to Combined-cycle power plant, each with the reason it gives.

• Energy efficiencyBroader topic: Reusing exhaust heat raises electricity output from the same fuel input.

• Fossil fuelBroader topic: It captures exhaust heat from natural-gas combustion for a second power cycle.

• Combined heat and powerCompared with: It raises electrical efficiency by reusing heat, but need not deliver useful heat to an external customer.

• Natural gasBroader topic: It converts natural gas into electricity with higher efficiency than a simple-cycle turbine.

• Thermal efficiencyBroader topic: Using exhaust heat again raises the plant's overall thermal efficiency.

• Heat engineRelated: It uses gas-turbine exhaust heat to drive a second heat engine.

• Rankine cycleCompared with: It couples a Brayton topping cycle to a Rankine cycle to use exhaust heat.

• Brayton cycleBroader topic: It captures Brayton-cycle exhaust heat in a bottoming Rankine cycle.

• Coal-fired power stationCompared with: It is a major alternative thermal plant, typically burning natural gas rather than coal.

• Carnot's theoremRelated: Using a wider temperature range helps approach the limits imposed on heat-to-work conversion.

• Cooling towerRelated: Its steam-cycle condenser may reject heat through a cooling tower.

• Waste heatCompared with: Its second cycle captures some gas-turbine exhaust heat rather than discarding it.

• Electricity generationBroader topic: It captures exhaust heat from gas generation to produce additional electricity.

• Dispatchable generationBroader topic: It is a common dispatchable generator, though its response is slower than a simple-cycle gas turbine’s.

• Load followingBroader topic: Combined-cycle plants can provide flexible generation, though their response depends on configuration and operating state.

• Thermal power stationBroader topic: It recovers gas-turbine exhaust heat to produce additional power.

• Fossil fuel power stationBroader topic: It captures gas-turbine exhaust heat to make additional electricity.

• Thermodynamic efficiencyBroader topic: Using exhaust heat to generate additional power raises overall fuel-to-electricity efficiency.

• CogenerationCompared with: It boosts electrical output, but is not cogeneration unless useful heat is also supplied.

• Load-following power plantBroader topic: Combined-cycle units often balance efficiency with the ability to vary output.

• Micro combined heat and powerNarrower topic: It applies heat recovery at utility scale rather than in an individual building.

• Base loadRelated: Its operating flexibility can support both persistent demand and changes in demand.

• Gas-fired power plantBroader topic: Its heat-recovery steam cycle captures energy that a gas turbine would otherwise exhaust.

• Gas-turbine engineRelated: It improves electricity-generation efficiency by using exhaust heat that a simple-cycle turbine would discard.
