Princeton operates a gas turbine engine that produces electricity and heat for steam. Derived from the same engine that propels the F/A-18 Hornet and F117 Nighthawk a.k.a. “stealth fighter” aircraft, the LM-1600 can produce over 15 megawatts of power, enough to power most of campus.

Princeton’s co-generation facility squeezes maximum efficiency out of the engine, by capturing the hot exhaust and using it to pre-heat feed-water before it enters the boilers.
