Sell Your Mitsubishi M501F Gas Turbine

Genloop buys Mitsubishi M501F gas turbines and the combined cycle plants built around them as principal, and handles the removal.

01 · The machine

The Mitsubishi half of the 501F.

The M501F is the Mitsubishi line of the F-class machine that Mitsubishi Heavy Industries and Westinghouse designed together from 1986 and shop-tested at Takasago in 1989. The first four ran at Lauderdale, Florida, in 1993 at 158 MW. When Siemens bought Westinghouse’s business in 1998 the two lines parted, and Mitsubishi Power now rates the M501F at 185 MW in simple cycle and 285 MW as a one-on-one combined cycle. It is air cooled, with 16 dry low NOx combustor cans, and turns at 3,600 rpm for 60 Hz grids. The 50 Hz machine is the M701F.

02 · What sets the value

What a buyer prices.

Two M501Fs of the same year can be far apart in price. These are the reasons.

Which version

An early unit at 158 MW, an M501F3 at 185 MW and a unit with the F4 upgrade are priced as different machines, and the upgrade stretches the inspection interval as well as the output.

Cycle position

Equivalent hours and starts since the last hot gas path inspection, not total hours. Mitsubishi’s current hot gas path parts are rated for 32,000 hours or 1,200 starts; earlier hardware runs less.

Rotor

Mitsubishi calls for a comprehensive rotor inspection at 100,000 hours or 12 years, which qualifies the rotor for another 100,000 or 12. A buyer asks where your rotor stands against that.

Fleet hardware

The 501F users group has tracked compressor hook-fit wear and diaphragm seal hardware on the M501F, and turbine disc cracking across the family. A buyer asks which fleet fixes the unit has had.

Who can support it

Mitsubishi Power, PSM, GE Vernova and independent shops all supply parts and repairs for the 501F family, and 501F owners went from two suppliers to five in fifteen years. A frame with that much support is easier to place.

Controls and the plant

Units run on Mitsubishi’s Diasys Netmation, whose spares the users group is now watching. The controls, the generator, the step-up transformer and, in combined cycle, the HRSG and steam turbine are priced with the unit.

03 · Where it goes

Where an M501F goes next.

A new F-class machine ordered today arrives years from now. An installed M501F that can be moved does not wait in that queue.

Combined cycle rebuilds

Blocks of 285 MW and up, relocated where a new plant would take years to deliver.

Data center power

Large baseload for sites whose load arrives before the grid connection does.

Utility capacity

Firm capacity for systems that are short of it before new generation arrives.

60 Hz markets

The Americas, Saudi Arabia, Korea, Taiwan, the Philippines and about half of Japan run at 60 Hz.

05 · Questions

What Mitsubishi M501F owners ask first.

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

What is a used Mitsubishi M501F worth?

It depends on the version, where the unit sits in its maintenance cycle, the state of the rotor, which fleet modifications have been done, and whether it sells with the plant around it. 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.

Is an M501F the same as a Westinghouse W501F?

They share a design. Mitsubishi and Westinghouse developed the 501F together from 1986, and the lines parted after Siemens bought Westinghouse’s business in 1998. Parts and upgrades from Mitsubishi, PSM and GE Vernova cover both, and Genloop buys both.

Does Genloop buy a whole M501F combined cycle plant?

Yes. Genloop buys M501F units on their own, as complete generating sets, and as combined cycle blocks with the HRSG, steam turbine, generators and transformers, bought whole and relocated whole.

Does Genloop buy M501Fs 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 M501F be moved to a 50 Hz grid?

No. The M501F turns at 3,600 rpm and makes 60 Hz, and it cannot be economically converted. The 50 Hz machine is the M701F. Its buyers are in 60 Hz markets: the Americas, Saudi Arabia, Korea, Taiwan, the Philippines and about half of Japan.

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.
