Genloop buys Siemens and Westinghouse 501D5 and 501D5A gas turbines as principal, running, idle or mothballed, and handles the removal.
The 501D5 is a heavy-frame gas turbine that Westinghouse introduced at the start of the 1980s, rated at about 96 to 107 MW. The 501D5A followed in the mid-1990s at about 120 MW. Siemens bought the business in 1998 and later named the engine the SGT6-3000E. It turns at 3,600 rpm and serves 60 Hz grids.
Two 501D5s with the same nameplate can be far apart in price. These are the reasons.
The D5 is rated at about 96 to 107 MW and the D5A at about 120 MW. Which one it is, and what has been uprated since, sets the starting point.
Equivalent hours and equivalent starts since the last hot gas path inspection and the last major, not total hours. The hot gas path interval users cite for the fleet is 24,000 equivalent hours or 900 equivalent starts.
The fleet leaders had passed 235,000 hours by 2012. Siemens runs a rotor and casing inspection to justify operation beyond 100,000 hours, and a buyer asks whether yours has had it.
Most units run the DF42 combustor with water injection, and a few have dry low NOx burners. The permit a unit can meet decides where it can go.
Siemens’ current range no longer lists the model, but Siemens, Mitsubishi and independent repair shops support the fleet, and its users group still meets every year.
Units were delivered on Westinghouse controls and many have since moved to T3000 or Ovation. The controls, the generator, the auxiliaries and the step-up transformer are priced with the turbine.
A block of 100 MW at 60 Hz that can be moved is useful to anyone who cannot wait for a new machine.
Process sites that need power and steam, the duty much of the fleet was built for.
Simple cycle capacity that runs a few hundred hours a year and is paid to be there.
Baseload for sites whose load arrives before the grid connection does.
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 whether it is a D5 or a D5A, where it sits in its maintenance cycle, the state of the rotor, its combustion system and controls, and whether it sells as a complete generating set. 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. W501D5, 501D5 and SGT6-3000E are names for the same engine. Westinghouse built it, Mitsubishi built it under license, and Siemens renamed it after buying the business in 1998. Genloop buys all of them.
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.
Either. Genloop buys a 501D5 as a complete generating set, with its generator, auxiliaries, controls and step-up transformer, or with the HRSG and steam turbine as a combined cycle or cogeneration block.
No. The 501D5 turns at 3,600 rpm and makes 60 Hz, and it cannot be economically converted. Its buyers are in 60 Hz markets: the Americas, Saudi Arabia, Korea, Taiwan, the Philippines and about half of Japan.
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.
D5 or D5A, serial number, rating, fuel, and what is included: generator, transformer, HRSG, balance of plant.
Equivalent hours and starts, trips, and the duty the unit ran: base load, cogeneration, peaking.
The last combustor, hot gas path and major inspections, with dates and open findings. Gaps are normal; say where they are.
Rotor hours and any rotor inspection, the combustion system, and the control system now fitted.
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.
