Power generation turbines convert the energy of a working fluid (gas, steam, water) into mechanical energy, which then drives a generator to produce electricity. The power generation turbines market includes gas turbines, steam turbines, and hydro turbines. This article focuses on gas turbines. Gas turbines are used in simple cycle (peaking), combined cycle (baseload, high efficiency), and cogeneration (CHP) plants. As the grid evolves, the power generation turbines market is shifting toward more flexible, efficient units.

The broader gas turbine market is a major segment. The power generation turbines market for "combined cycle gas turbine" (CCGT) plants have the highest efficiency (up to 64%). A CCGT plant uses a gas turbine's hot exhaust to generate steam for a steam turbine. The power generation turbines market for "single-shaft" (gas and steam turbine on same shaft) and "multi-shaft" configurations are available.

The power generation turbines market for "simple cycle" plants (just the gas turbine) are used for peaking (hours to a few days per year). They have lower efficiency (35-40%) but lower capital cost. The power generation turbines market for "aero-derivative" gas turbines (peaking) have fast start-up. The power generation turbines market for "open cycle" plants are the simplest.

The power generation turbines market for "cogeneration" (CHP) uses waste heat for district heating or industrial processes. The power generation turbines market for "district heating" is common in cold climates (e.g., Northern Europe). The power generation turbines market for "industrial" CHP is used in paper mills, refineries, and chemical plants. The power generation turbines market for "combined cycle CHP" is also used.

The power generation turbines market for "grid stability" services (frequency regulation, spinning reserve) is a growing application. The power generation turbines market for "black start" capability (starting without grid power) is required for some units. The power generation turbines market for "renewable" integration (backing up solar and wind) is the key role.

Looking ahead, the power generation turbines market will see the deployment of "hydrogen" capable gas turbines. The power generation turbines market for "carbon capture" on the exhaust (post-combustion) is being developed. The power generation turbines market for "sCO2" (supercritical carbon dioxide) cycles (even higher efficiency) is a future possibility.
