Genloop buys GE 7FA gas turbines and the combined cycle plants built around them as principal, and handles the removal.
The GE 7FA, now designated 7F, is a heavy-frame F-class gas turbine. GE rates the 7F.03 (the 7FA.03) at 178 MW in simple cycle, the 7F.04 at 201 MW and the 7F.05 at 239 MW. It turns at 3,600 rpm, so it serves 60 Hz grids; the 50 Hz machine is the 9FA.
Two 7FAs of the same year can be far apart in price. These are the reasons.
A 7FA.03, a 7F.04 and a 7F.05 are different machines at different ratings. The 7F.05 has a 14-stage compressor where the earlier versions have 18. The version, and what has been fitted since, sets the starting point.
Hours and starts since the last hot gas path inspection, not total hours. The baseline hot gas path interval on a 7FA.03 is 24,000 factored hours or 900 factored starts. GE’s later hardware is approved for 32,000 hours or 1,250 starts.
Behind the inspection clock is the rotor. GE’s limit for the 7FA rotor is 144,000 factored hours or 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, DLN 2.6+ combustion and the 7F.04-200 package each raise output or lengthen intervals. GE says more than half of the 7F fleet has Advanced Gas Path. A buyer asks which of them your unit has.
GE no longer produces the Mark V and new parts for it are not available. Mark VIe is the current system, and some upgrades require it. A buyer with a Mark V unit prices in the change.
A 7FA sold with its generator, step-up transformer and, in combined cycle, its HRSG and steam turbine is a plant a buyer can install. A bare turbine needs everything else sourced, matched and commissioned.
A new F-class machine ordered today arrives years from now. An installed 7FA that can be moved does not wait in that queue.
Blocks relocated and rebuilt where a new plant would take years to deliver.
Large baseload for sites whose load arrives before the grid connection does.
Firm capacity for systems that are short of it before new generation arrives.
The Americas, Saudi Arabia, Korea, Taiwan, the Philippines and about half of Japan run at 60 Hz.
The short answers. The detail is in the contract, and in the call that comes before it.
It depends on which version it is, where it sits in its maintenance cycle, how much rotor life is left, what upgrades are fitted, 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.
Yes. Genloop buys 7FA 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 7FA turns at 3,600 rpm and makes 60 Hz, and it cannot be economically converted. The 50 Hz machine is the 9FA. A 7FA’s buyers are in 60 Hz markets: the Americas, Saudi Arabia, Korea, Taiwan, the Philippines and about half of Japan.
The version, 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 controls generation, and what is included with the 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 (7FA.03, 7F.04, 7F.05), serial number, fuel, and what is included: generator, transformer, HRSG, steam turbine, balance of plant.
Fired hours, starts and trips, and the duty the unit ran: base load, cycling, peaking.
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+, 7F.04-200, controls.
The window in which the equipment must be gone, crane and road access, and any export or permit requirements.
Who owns the equipment, and what has to be released at closing.
