Genloop buys Alstom GT11N2 gas turbines as principal, running, idle or mothballed, and handles the removal and export.
The GT11N2 is a heavy-frame gas turbine built by ABB and then Alstom from the mid-1990s, and supported by GE Vernova since GE bought Alstom’s power business in 2015. It is rated at about 115 MW in simple cycle. The turbine turns at 3,600 rpm, driving a 60 Hz generator directly and a 50 Hz generator through a gearbox.
With fewer than sixty units in the world, every GT11N2 is priced on its own history. These are the things a buyer looks at.
Equivalent operating hours since the last major inspection, not total hours. With GE’s M upgrade the interval can run to 48,000 equivalent hours.
GE’s M upgrade adds up to 15 MW and up to 1.9 points of efficiency, or trades some of that for a longer interval. Whether it is fitted is one of the first things a buyer asks.
The single silo combustor comes in versions for natural gas and oil and for low-calorific gases such as blast furnace gas. A unit built for a steel mill is a different machine to place from one built for pipeline gas.
A 60 Hz unit drives its generator directly and a 50 Hz unit has a gearbox. Which one it is decides where it can go without rework.
GE counted 58 GT11N2 units worldwide in 2023, 57 of them in service. Parts and experience sit with a handful of firms, and a buyer weighs that.
A turbine sold with its generator, gearbox if it has one, auxiliaries, controls and step-up transformer is a plant a buyer can install. A bare turbine needs everything else sourced, matched and commissioned.
The GT11N2 was built for both 50 Hz and 60 Hz grids, and for fuels that most turbines cannot burn.
Operators of the frame, for whom another unit shares spares, tooling and experience.
Sites that burn blast furnace gas, where few other turbines can run.
A block of 115 MW for systems short of firm power before new machines arrive.
One or more units set in front of a steam turbine.
The short answers. The detail is in the contract, and in the call that comes before it.
It depends on where the unit sits in its maintenance cycle, whether the M upgrade is fitted, the fuel it was built for, whether it is a 50 Hz or 60 Hz unit, and how complete the package is. 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.
GE Vernova, which took on Alstom’s gas turbine fleet when it bought the business in 2015, and a number of independent repair firms.
The frame serves both. The turbine turns at 3,600 rpm, driving a 60 Hz generator directly and a 50 Hz generator through a gearbox. A given unit is built as one or the other.
Genloop looks at all of them, case by case.
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.
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.
No. Genloop buys as principal and takes title, so there is no fee, no marketing period and no waiting for a buyer to appear.
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.
Serial number, 50 Hz or 60 Hz, combustor version, fuel, and what is included: generator, gearbox, transformer, HRSG, balance of plant.
Equivalent operating hours, starts and trips, and the duty the unit ran.
The last A, B and C inspections, with dates and open findings. Gaps are normal; say where they are.
Whether the M upgrade is fitted and in which mode it runs, and the control system.
The window in which the equipment must be gone, crane, road and port access, and any export or permit requirements.
Who owns the equipment, and what has to be released at closing.
