The FT4000® SWIFTPAC® gas turbine package is available in both single- and dual-engine configurations, it offers greater than 41 percent simple-cycle efficiency and a nominal 60 to 140 megawatts of power within a modular design that is built utilizing over fifty years of aero-derivative design and packaging experience. Utilizing the core technology derived from the proven Pratt & Whitney® PW4000® turbofan engines, the all-new SWIFTPAC® gas turbine packages are designed to provide reliable peaking and base-load power with a relatively compact footprint. This is accomplished by coupling either one or two FT4000® engines to one electric generator. The modular design includes proven features of the successful FT8® SWIFTPAC® and MOBILEPAC® gas turbine package designs.
