Sell Power Equipment

How Selling Works

SecondWatt lists surplus, decommissioned, and cancelled-project power equipment through a moderated flow. A submission is reviewed before it becomes visible, published as an anonymised record, and matched against active buyer requirements. Seller identity, exact location, and any re-identifying condition detail stay masked until SecondWatt makes the introduction and both sides agree to proceed.

What SecondWatt Accepts

Gas turbines, diesel and natural gas generators, power and unit-substation transformers, medium and low voltage switchgear, UPS systems, automatic transfer switches, station batteries, and balance-of-plant equipment. Units may be new surplus, refurbished, or used. Category context for each of these sits on the gas turbine, generator, transformer, switchgear, and UPS hubs.

What a Submission Needs

Manufacturer and model — selected from the SecondWatt model catalogue so listings stay comparable — capacity, voltage class, year of manufacture, operating hours where applicable, and current status. Nameplate photographs and test or service records shorten the review. Model-level specifications are already published, so the submission only has to supply what is specific to the unit.

Pricing Context Before You List

The Pricing Index reports each category under the four-tier framework — New OEM, Gray Market, Refurbished, and Used — as a midpoint with a percentile band rather than a single number. Sellers use it to set an asking range that survives buyer diligence. Sourcing rules behind those bands are documented on the methodology page.

Buyer Side

Buyers reach listings through category hubs, model dossiers, and the technology comparison in the Power Intelligence Tool. Requirements arrive with capacity, timeline, and site constraints attached, so an introduction carries context rather than an anonymous enquiry. Acquisition capital is arranged separately through equipment financing.

How Anonymity Is Preserved

A published listing shows the model, capacity, voltage class, year, and condition tier. It does not show the seller's name, the site, or any detail specific enough to identify the owner by inference — a common failure in surplus listings, where a rare model plus a region is enough to name the plant. SecondWatt reviews every submission for that risk before it goes live and will generalise a field rather than publish a re-identifying one.

Identity is disclosed only when both sides agree to an introduction. Until then, buyer questions come through SecondWatt and answers go back the same way, which keeps the seller's disposal programme out of public view while the unit is still being marketed.

What Review Checks

Review confirms three things: that the model exists in the published catalogue, that the stated capacity and voltage class are internally consistent with that model, and that the condition claim is supported by whatever documentation was supplied. A unit described as refurbished with no overhaul record is republished as used rather than rejected outright. Photographs of the nameplate settle most questions in one pass.

Timing and Withdrawal

Sellers keep control of the listing. A unit can be withdrawn at any point before an introduction, and a listing that has gone stale — sold elsewhere, or scrapped — should be withdrawn rather than left live, because unresolved listings distort the transaction data behind the pricing bands. There is no exclusivity requirement; equipment listed with a broker elsewhere can still be listed here.

Common Seller Mistakes

Three recur. Pricing to original purchase cost rather than to the current band for the condition tier, which stalls the listing. Omitting operating hours or service history, which forces buyers to assume the worst. And describing a unit by a marketing name rather than the OEM model designation, which keeps it out of the comparison tables buyers actually use. The model catalogue in the marketplace resolves the third one directly.
