Gas Turbine Industry Statistics

Gas turbine demand is forecast to grow at a 10.5% CAGR for the global gas turbine market through 2032, while industrial turbines face a 6.5% CAGR for 2023 to 2030, setting up a sharper growth split than most buyers expect. The page ties that momentum to hard performance and compliance realities like 95%+ availability targets, NOx limits from ppmvd to mg/Nm3, and quantified efficiency gains from washing and water or steam injection.
