Selling a Transformer in San Ramon
We buy surplus, used and failed electrical transformers in San Ramon, CA and throughout Contra Costa County. Padmount, oil-filled, dry-type, pole-mount and substation-class units from 15 kVA to 100 MVA, in any condition — working, de-energized, surplus or internally failed. Send a photograph of the nameplate and we will price the unit the same day. Every purchase includes the freight and the rigging at our cost.
The California market for used transformers
What comes available in this state is shaped by what it runs: aerospace and defense in Southern California, food processing through the Central Valley, semiconductor and biotech in the Bay Area, and the largest utility-scale solar fleet in the country. On the utility side, Pacific Gas & Electric, Southern California Edison, SDG&E, LADWP all operate here, and surplus programs and system upgrades release both distribution and station-class equipment. Moving it out of San Ramon means I-5 and Highway 99 run the length of the state, and the Ports of Los Angeles, Long Beach and Oakland handle our export freight. Notably, California's solar repowering activity and aggressive grid-modernization spending release more surplus transformer capacity than any other state, and the environmental documentation requirements are the strictest — both of which suit how we work.
Why a mid-size city like San Ramon is easy for us
Mid-size markets are frequently where the best-value equipment sits, because there is less local competition bidding on it. A well-maintained padmount or a copper-wound dry-type out of a San Ramon plant or school district often carries strong resale value and simply has not had a buyer with a truck show up. We are that buyer, and we consolidate San Ramon pickups with other California freight so the haul cost never lands on your side of the ledger.
Single units and small lots
You do not need a yard full of equipment to get our attention here. One 750 kVA padmount, three pole-mount cans on pallets, a pair of dry-types out of a mechanical room — we will quote it and we will schedule it. If a single small unit does not justify a dedicated truck immediately, we will tell you honestly and either hold it for the next California run or price it to move now.
Removal and Value
Access constraints we handle in San Ramon
Very few transformers sit somewhere convenient. We routinely remove units from basement vaults, upper-floor electrical rooms, fenced substation yards with a single gate, roof-level mechanical decks and live plant floors under escort. Where a unit will not fit through the opening it came in through, we handle door-frame removal, wall coring or on-site disassembly. Where the street must be occupied, we pull the permit. None of that is billed back to you.
Why lead times work in your favor
New transformer lead times have stayed long enough that used and surplus equipment holds unusually firm value. Buyers who need capacity in months rather than years will pay for a tested used unit. That demand is what lets us cover the crane, the riggers and the freight out of San Ramon and still write you a real check — the equipment is genuinely worth recovering rather than merely worth hauling away.
Equipment We Buy in San Ramon
Cast-Coil Transformers
Epoxy-encapsulated cast-coil units built for harsh, humid and high-load environments. Because they were expensive new and are durable used, they hold value better than any other dry-type.
300 kVA – 10 MVALots of 2 to 30 vault unitsNetwork & Vault Transformers
Submersible and vault-type network transformers with network protectors, pulled from underground vaults in dense urban grids. Awkward to remove, which is exactly why we get called.
300 kVA – 3000 kVAProject lots from 1 to 20 unitsStep-Up & Step-Down Transformers
Generator step-up units, collector-substation transformers and step-down service transformers coming out of retired generation, wind and solar repowering, and industrial service upgrades.
