What we buy
Ranges we buy on this page
This guide covers Dominion Energy interconnection in northeastern North Carolina and what the process demands of a transformer. It is for plant engineers, utility asset managers, facility directors, EPC contractors, and crews removing equipment from a generation site.

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
What it is
Dominion Energy interconnection is the review and approval process for connecting generating equipment to the utility system. In northeastern North Carolina, start by confirming the serving utility at the actual meter location.
A county name alone does not establish whether Dominion handles the proposed connection.
The application identifies the generating source, point of interconnection, transformer, and protective equipment. Dominion's applicable procedures depend on the project and connection arrangement.
The review can involve engineering studies, an interconnection agreement, required modifications, and commissioning evidence before permission to operate is issued for that site.
Local reality
Why it matters when you sell
A transformer removed from a Dominion-connected solar site carries more context than its kVA rating. The approved one-line diagram can identify winding connections, grounding, and ownership boundaries.
Those details help separate the project-owned step-up transformer from utility equipment that the site operator cannot authorize for removal.
For a canceled project in northeastern North Carolina, application drawings may describe equipment that was never installed or approved. Match each document to the tank serial number and revision date.
Transformer Buyers NC buys used, surplus, failed, and obsolete transformers, but project approval is not transferable equipment certification.
Around the site
The numbers
Record nameplate kVA, primary and secondary voltage, phase count, frequency, impedance, and tap positions. A 480 V winding and a medium-voltage winding describe a common step-up arrangement, not a Dominion acceptance standard.
The required voltage must match the specific connection design and the utility's engineering review.
Include winding connection, basic impulse insulation level, cooling designation, and temperature rise in the equipment record. A grounded-wye winding and a delta winding produce different zero-sequence paths.
Dominion's protection review needs the actual arrangement, while removal planning needs dimensions, total weight, and oil quantity from verified records.
Where it sits
Common mistakes
Do not treat a Dominion interconnection application as permission to energize. An accepted submission, completed study, signed agreement, and permission to operate are different milestones.
Keep the site's current approval documents together, and distinguish proposed transformer specifications from the ratings on the unit actually sitting on the pad.
Another mistake is assuming a bayonet fuse or primary elbow completes the generation protection scheme. Transformer protection and interconnection protection serve different purposes.
Missing relay settings, an undocumented neutral connection, or substituted winding configuration can leave Dominion reviewing a design that no longer matches the installed equipment.
On the ground
How it affects value
Interconnection records help establish what a northeastern North Carolina transformer was built to do and whether its history is traceable.
A matching nameplate, approved one-line, factory test report, and maintenance file support a clearer assessment than a solar project label attached to an otherwise undocumented tank.
Dominion approval does not erase physical damage or establish suitability for another site. Leaking radiator gaskets, cracked bushings, abnormal dissolved-gas results, and damaged cable compartments remain separate concerns.
For a failed unit, preserve fault reports and oil test records so its electrical history stays with its serial number.
Local reality
What to do next
Before discussing removal, assemble the Dominion project identifier, interconnection agreement, latest one-line diagram, nameplate photographs, and ownership documentation. Identify which disconnect establishes the work boundary.
Have qualified personnel coordinate isolation, absence-of-voltage verification, and grounding under the site's procedures; an idle inverter does not prove the transformer is deenergized.
For pickup from a northeastern North Carolina generation site, photograph the pad, access road, radiator clearance, and lifting provisions. Confirm whether cable removal or oil handling needs separate coordination.
Transformer Buyers NC needs the equipment details and removal conditions to evaluate the unit and plan an appropriate pickup.

Questions
Straight answers
Equipment types
Does Dominion approval follow a removed transformer?
Do not assume it does. Dominion interconnection approval addresses a particular project, connection point, and reviewed design. Moving the transformer to another North Carolina site requires checking that site's applicable process. Keep the original records as equipment history, not as permission to reconnect elsewhere.
Service area
Which transformer records help explain the connection?
Start with the nameplate, latest approved one-line diagram, factory test report, and Dominion correspondence identifying the reviewed configuration. Include relay settings and commissioning records where applicable.
Payment
Can a failed interconnection transformer be considered?
Transformer Buyers NC buys failed transformers as well as used, surplus, and obsolete units. For a Dominion-connected site, document the fault, ownership, isolation status, oil condition, and access restrictions.
