Sell a GSU transformer.

For owners of generator step-up transformers left at retired plants, canceled projects or in storage.

When a plant retires or a project is canceled, its generator step-up transformer is often still sound. New plants need GSUs, and new ones take years to arrive. We take yours to buyers whose generator it fits, keep your name private until you sign, and are paid only when it sells.

How selling works

  1. 01A short call about the unit, the plant it served and the generator it was matched to.
  2. 02A fee agreement before any buyer hears your name or site.
  3. 03A summary to buyers whose generator and grid voltage it fits.
  4. 04Tests and contract with the buyer you choose. Our fee is paid at close.

What affects the price

A GSU sells only to a buyer whose generator and grid voltage it matches. After that, these decide the price.

  • MVA and voltages

    The low side has to match the generator and the high side the grid connection.

  • Impedance

    Buyers check it against their generator design and fault studies.

  • Year and test history

    Factory tests, then later oil and electrical tests, show how it has aged.

  • How it was left

    Energized until the plant closed, drained, or kept under nitrogen, and whether that was logged.

  • Accessories and cooling

    Bushings, radiators or coolers, and the monitoring that came with it.

  • Removal from the site

    A retiring plant often has a demolition date. Clear access and time to remove it help the price.

What to have ready

  • A nameplate photo: maker, serial number, MVA and voltages
  • The generator it served, and its years in service
  • Impedance and the cooling equipment fitted
  • Oil test results and the dissolved gas (DGA) history
  • Whether it is still on its pad, and the plant's demolition timeline
  • Who at the plant can sign off on a sale

Questions

What happens to a GSU when its plant retires?

It often stays on its pad while the plant is taken down. The owner can scrap it, keep it as a spare for another plant, or sell it. Selling before the demolition date is fixed gives a buyer time to test and remove it.

Will my GSU fit a buyer's generator?

Only if the voltages, MVA and impedance line up closely enough for the buyer's engineers. We send those figures in the first summary, so only buyers it can fit spend time on it.

Why do buyers want a used GSU?

A plant can't send power to the grid without one, and new large transformers take years to build. A sound unit that exists today can bring a project's start date forward.

Can a GSU from a canceled project be sold if it was never installed?

Yes. If it's still crated or in storage, buyers will ask how it was kept and for the factory test report.

The plant is being sold or demolished. Who can approve the sale?

Whoever holds title to the transformer signs. On the first call we check who that is, who else must approve, and the date the site has to be clear.
