Gas turbines play a preeminent role in the stationary power generation marketplace and are expected to remain a critical part of the market mix for the foreseeable future. Alternative technologies compete with gas turbines in certain size classes, but at power generation levels above 5 MW, gas turbines offer the most attractive option due to their relatively low capital, operating, and maintenance costs. The configurations for these systems involve high efficiencies as well. These engines are being looked to by the US Department of Energy and the major OEMs for clean power production, especially considering the use of renewable fuels. As a result, the market will continue to demand gas turbines for the foreseeable future.
