Sell Your FT8 Gas Turbine

Genloop buys Pratt & Whitney FT8 packages, SWIFTPAC units and FT8 MOBILEPAC trailers as principal, running, idle or mothballed, and handles the removal.

01 · The machine

A JT8D at its core, now built by Mitsubishi.

The FT8 is an aeroderivative gas turbine built around the Pratt & Whitney JT8D-219, the engine of the 727, 737 and MD-80. It entered service in 1991 at about 25 MW, and the current SWIFTPAC package makes about 31 MW from one engine or 62 MW from two on a single generator. The trailer-mounted MOBILEPAC makes 31 MW at 60 Hz and 29 MW at 50 Hz. The power turbine is free, so it drives the generator directly at 3,600 or 3,000 rpm with no gearbox. Pratt & Whitney Power Systems became PW Power Systems when Mitsubishi Heavy Industries bought it in 2013, and is Mitsubishi Power Aero today.

02 · What sets the value

What a buyer prices.

An FT8 is two assets, the gas generator and the package around it, and each carries its own history.

Which package

A PowerPac, a TwinPac, a SWIFTPAC 30, a SWIFTPAC 60 with two engines on one generator, or a MOBILEPAC on trailers. The package decides who the buyers are before the engine does.

Engine time

Hours and starts on the gas generator since its last hot section inspection and its last major. The published intervals are 25,000 hours to the hot section and 50,000 to the major, both shop events on the removed gas generator.

Shop visit history

Which shop did the last hot section or major, and what was replaced. Gas generators and power turbines are swapped and leased across the fleet, so the engine in the package today may not be the one it was delivered with.

Combustion

Most FT8s hold NOx at 25 ppm with water injection; a dry low NOx version exists on part of the fleet. Dual fuel units have more places they can go, and on dual fuel the liquid fuel nozzles are a known wear item.

Controls

Packages came on Woodward NetCon or MicroNet. Units moved to MicroNet Plus with the OEM’s Gen II software, or to an Ovation retrofit, are priced ahead of those still on NetCon.

Frequency

The free power turbine runs at 3,600 or 3,000 rpm with no gearbox, and the OEM offers the same unit reconfigured for either grid. Genloop will take an FT8 across frequencies, with the conversion priced in.

03 · Where it goes

Where an FT8 goes next.

A 30 MW unit that starts in ten minutes and travels on trailers goes where power is needed before anything permanent can be built.

Data center bridge power

Mitsubishi Power names the FT8 MOBILEPAC as a bridging unit for sites whose grid connection is years out.

Emergency and seasonal capacity

MOBILEPACs were sent to Puerto Rico in 2019 and put on the Texas grid in 2022 for the same reason: they are running within days of arriving.

Peaking and grid support

Fast-start capacity that is paid to be available, in 30 MW blocks.

Either grid

Direct drive at 3,000 or 3,600 rpm, which widens where a unit can go.

05 · Questions

What Pratt & Whitney FT8 owners ask first.

The short answers. The detail is in the contract, and in the call that comes before it.

What is a used FT8 worth?

It depends on the package, the gas generator’s hours since its last hot section and major, which shop did the work, the combustion and control systems, how complete the package is, and its records. No public database records what used turbines actually sell for, so advertised prices are asking prices. Genloop makes a firm offer after its own engineers have inspected the unit.

Does Genloop buy FT8 MOBILEPAC trailers?

Yes. Genloop buys MOBILEPAC mobile units, SWIFTPAC packages and the older PowerPac and TwinPac packages, running, idle or mothballed.

Does Genloop buy FT8s that are not running?

Yes. Genloop buys units that are running, idle or mothballed. A unit that has been mothballed for several years is looked at case by case.

Can an FT8 move between 50 Hz and 60 Hz?

Yes. The free power turbine turns at 3,600 rpm for 60 Hz or 3,000 rpm for 50 Hz with no gearbox, and the OEM offers the same unit reconfigured for either grid. Genloop will take an FT8 across frequencies, with the conversion priced in.

Is the FT8 still supported?

Yes. Mitsubishi Power Aero overhauls gas generators in Connecticut and supplies parts and field service, an FT8 users group met for the first time in 2024, and independent shops repair fuel nozzles and hot section parts.

Who handles dismantling and removal?

Genloop does. Dismantling, export compliance and transport are Genloop’s scope, insured throughout, and written into the same contract as the purchase. The site is handed back on the schedule the contract sets.

Does Genloop charge a fee?

No. Genloop buys as principal and takes title, so there is no fee, no marketing period and no waiting for a buyer to appear.

06 · Direct

Tell us about the asset.

Every enquiry is read by the people who inspect, value and buy the equipment, and answered directly. Owners rarely have everything; send what exists and Genloop fills the gaps on site.

What to send, if you have it
Package and engine

Package type, engine model (FT8, FT8-3 or FT8+), gas generator and power turbine serial numbers, fuel, and what is included.

Engine hours and starts

Fired hours and starts on the gas generator now installed, in total and since its last hot section and major.

Shop visit records

Shop reports for each hot section, major or repair, and any lease or exchange engines that have run in the package.

Controls and emissions

NetCon, MicroNet, MicroNet Plus or a retrofit; water injection or dry low NOx; and any catalyst fitted.

Site and removal constraints

The window in which the equipment must be gone and any export or permit requirements. For a MOBILEPAC, whether it is still on its trailers and where it is parked.

Title and encumbrances

Who owns the package and who owns the engine, which are not always the same party, and what has to be released at closing.
