What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete transformers from biogas and digester facilities across North Carolina. This page covers equipment identification, project deadlines and removal planning for plant engineers, farm project owners, EPC contractors and demolition crews.

Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.
On the ground
How Biogas and Digesters use power
A digester facility consumes power for feed pumps, mixers, gas treatment and controls before its generator exports electricity. Intermittent generation can put a generator step-up transformer through repeated load changes.
The one-line diagram shows whether auxiliary loads share that transformer or use a separate utility service.
Corrosive gas is a site condition, not a transformer cooling medium. Hydrogen sulfide from untreated biogas can attack exposed metals where gas escapes or ventilation carries it toward electrical equipment.
Inspect enclosure hardware, grounding connections and radiator surfaces, and document the gas source rather than assuming every tank is affected.
Local reality
The equipment you will find
Padmounts may serve digester auxiliaries or connect generation to a medium-voltage circuit. Record primary and secondary voltages, kVA, impedance and winding connections from the nameplate.
Photographs should show elbow compartments, bushings and bayonet fuse access without opening energized doors or disturbing the site's existing protective barriers.
Generator step-up units require a review of the generator-side voltage and utility-side connection. Grounding transformers need separate identification because their function and duty differ from power transformers.
Include any zigzag designation, neutral connection and associated grounding resistor information; a tank photograph alone will not establish the assembly's electrical purpose.
Around the site
The state's Biogas and Digesters footprint
North Carolina's coastal plain includes hog and poultry digester projects where electrical equipment sits beside agricultural operations. Access may run along farm lanes rather than industrial roads.
Identify the county, nearest public road and transformer pad location so a removal plan accounts for drainage ditches, culverts and livestock traffic.
Projects in counties such as Duplin and Sampson can have long cable runs between digesters, gas equipment and the interconnection point. Confirm which transformer belongs to the project owner and which equipment remains under utility control.
A property address alone does not define the boundary of the proposed removal.
Where it sits
The decision chain
The farm owner may control the land while a separate biogas developer owns the generator and transformer. Before discussing removal, establish asset ownership through purchase records, lease schedules or project transfer documents.
The person operating the digester controls may not have authority to release electrical equipment from the site.
An EPC contractor or plant engineer should identify the transformer on the approved one-line diagram and explain what remains operational. Utility approval may be needed for work at the interconnection boundary.
For a failed generator step-up unit, distinguish the failure report from the authorization to disconnect and remove it.
On the ground
Schedule and regulatory pressure
An offtake contract can set the energization date for a biogas generation project. Replacing or removing a transformer must fit the outage, testing and utility witness schedule.
Provide the contractual milestone and the actual disconnection window separately; neither confirms that cables are isolated or that equipment is ready for lifting.
Oil-filled equipment also needs a documented environmental review before transport. Share existing fluid test results, including PCB information where applicable, and identify leaks at gaskets, drain valves or radiator joints.
Digester permits and gas-system approvals do not replace the requirements governing transformer fluid handling, spill response or electrical isolation.
Local reality
Removal logistics
A transformer pad beside a digester lagoon may leave little room for crane outriggers or a lowboy. Measure gate width, overhead clearance and the loading approach.
Check culvert capacity and ground conditions along the farm lane; a route used by feed trucks is not automatically suitable for concentrated lifting loads.
Before lifting, qualified personnel must isolate the transformer, verify absence of voltage and apply grounding as required by the work plan. Record cable ownership and termination locations before disconnection.
Keep the lift away from biogas piping, gas-treatment skids and classified areas, using verified weight, lifting points and suitable rigging.
Around the site
What to send us
Send a readable nameplate photograph, the relevant one-line diagram and views of all accessible sides of the transformer. For padmounts, identify dead-front or live-front construction from records or safely obtained photographs.
For generator step-up units, include generator voltage, winding configuration and any available test report following a trip or failure.
Include the North Carolina site address, ownership contact, energization deadline and planned isolation date. Describe corrosive gas exposure, oil leaks and missing bushings or radiators.
Access photographs should show the pad, farm lane, gate and nearby gas piping, with any restrictions on crane setup or hauling through active livestock areas.

Questions
Straight answers
Equipment types
Can you buy a failed digester generator transformer?
We buy failed generator step-up transformers from North Carolina digester projects. Provide the nameplate, trip history and any electrical or fluid test results.
Service area
Does corrosive biogas exposure prevent a transformer review?
Corrosive gas exposure does not automatically prevent a review. Document hydrogen sulfide exposure where known, enclosure corrosion and damaged grounding connections. Photographs of radiator joints, hinges and bushings help distinguish surface deterioration from defects that could affect handling, containment or safe access during removal.
Payment
What if the offtake deadline limits removal time?
Provide the offtake energization date alongside the confirmed outage and utility coordination requirements. A replacement schedule may leave only a short loading window at the digester pad.
Logistics
The decision chain: what should a seller know?
The farm owner may control the land while a separate biogas developer owns the generator and transformer. Before discussing removal, establish asset ownership through purchase records, lease schedules or project transfer documents.
