About the Pratt & Whitney FT4

The Pratt & Whitney FT4 is a two-shaft aero-derivative gas turbine derived from the JT4 aircraft engine. A workhorse of North American peaking power and pipeline compression, the FT4 is known for its fast-start capability and ability to operate on a wide range of fuels including natural gas, distillate, and crude oil.

Common Applications

Industries and use cases where the FT4 is most commonly deployed.

Peaking Power

Fast-start (under 2 minutes) capability makes the FT4 ideal for grid peaking and frequency regulation.

Pipeline Compression

Large North American fleet operating in natural gas transmission pipeline compression service.

Emergency Power

Reliable and rapid dispatch for emergency or standby generation at industrial facilities.

Mobile Power

Some FT4 packages are configured for mobile or trailer-mounted deployable power generation.

Buying a Used FT4 — What to Know

Used FT4 turbines are available in the $1M–$4M range. The large North American installed base means parts are accessible. Verify: hot section hours, transition duct condition, and combustor liner status. Many units have high hours but remain serviceable with HGP overhaul.

Frequently Asked Questions

Can the FT4 run on liquid fuel?

Yes. The FT4 was designed for multi-fuel operation including natural gas, distillate, residual fuel, and even crude oil in some configurations.

How fast can the FT4 start?

The FT4 can reach full load in under 2 minutes from a warm start, making it one of the fastest-starting turbines available for peaking service.

Are FT4 parts available?

Yes. The large installed base supports an active aftermarket. P&W and several independent MRO shops service FT4 hot sections and compressors.

What is the difference between FT4 and FT8?

The FT8 is a newer, higher-output (25–30 MW) turbine with significantly improved efficiency (~38%) versus the FT4's ~30%. FT8s command a premium but offer lower heat rate in service.
