Gas turbines are available in sizes ranging from approximately one to more than 300 megawatts (MW) and are used to meet diverse power needs, including propulsion, direct drive, and stationary electricity generation. For CHP applications, gas turbines typically have favorable economics in sizes greater than 5 MW. Gas turbines account for 52 GW of installed CHP capacity in the United States, representing 64% of the total installed CHP capacity. Gas turbines are well suited for industrial and institutional CHP applications because the high temperature gas turbine exhaust can either be used to generate high pressure steam or used directly for heating or drying.
