Genloop buys GE 9FA gas turbines and the combined cycle plants built around them as principal, and handles the removal and export.
The GE 9FA, now designated 9F, is a heavy-frame F-class gas turbine, an aerodynamic scale of the 60 Hz 7FA. GE rated the 9FA at about 256 MW in simple cycle and about 390 MW as a single-shaft combined cycle block; the current 9F.04 is rated at around 290 MW. It turns at 3,000 rpm and serves 50 Hz grids.
Two 9FA plants of the same size can be far apart in price. These are the reasons.
Hours and starts since the last hot gas path inspection, not total hours. The baseline hot gas path interval on a 9FA is 24,000 factored hours, and GE’s Advanced Gas Path hardware extends it to as much as 32,000.
GE gives an F-class rotor 144,000 factored hours and 5,000 factored starts. A unit near either figure needs a rotor exchange or a life extension, and a buyer prices that in.
Advanced Gas Path hardware adds up to 8 percent output. DLN 2.6+ combustion brings NOx down to 15 ppm, against the 25 ppm of the DLN 2.0+ system the 9FA shipped with. A buyer asks which your unit has.
A 9FA plant is either single-shaft, with the gas turbine, steam turbine and generator on one line, or multi-shaft with one or two gas turbines to a steam turbine. The arrangement decides what can be sold and moved separately.
Mark VIe is GE’s current system and the one its upgrades are built on. A buyer with an older panel prices in the change.
The HRSG, steam turbine, generator and step-up transformer. A complete block is rebuilt on a new site; a gas turbine on its own needs the rest sourced, matched and commissioned.
GE counts more than 400 9F units in over 40 countries. A relocated one goes where a 50 Hz grid needs a large block sooner than a new machine can arrive.
Whole blocks relocated and rebuilt where a new plant would take years to deliver.
Blocks of around 400 MW for utilities and independent producers short of firm capacity.
An F-class gas turbine set in front of an existing steam plant and its grid connection.
Europe, Africa, most of Asia and Australia run at 50 Hz.
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, how much rotor life is left, what upgrades are fitted, and how much of the combined cycle plant sells with 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.
Yes. Genloop buys 9FA 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.
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.
No. The 9FA turns at 3,000 rpm and makes 50 Hz, and it cannot be economically converted. The 60 Hz machine is the 7FA. A 9FA’s buyers are in 50 Hz markets: Europe, Africa, most of Asia and Australia.
Fired hours and starts, the date of the last hot gas path inspection and the last major, rotor hours and starts, the upgrades fitted, the shaft arrangement, and what is included with the gas turbine. Gaps are normal and Genloop fills them on site.
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.
Version, serial number, single-shaft or multi-shaft, fuel, and what is included: generator, steam turbine, HRSG, transformers, balance of plant.
Fired hours, starts and trips, and the duty the unit ran: base load, cycling, two-shifting.
The last combustion, hot gas path and major inspections, with dates and open findings. Gaps are normal; say where they are.
Rotor hours and starts, any rotor exchange or life extension, and what has been fitted: Advanced Gas Path, DLN 2.6+, controls.
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.
