Selling a Transformer in Mill Valley
Mill Valley sits inside the CA service territory of Pacific Gas & Electric, which means most of the distribution equipment coming out of buildings and yards here is standard-voltage, well-documented and genuinely resaleable. We buy it directly — padmount, dry-type, oil-filled, pole-mount and station-class — and we cover all freight and rigging to remove it.
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 Mill Valley 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.
A small community is not too small to sell
We regularly buy equipment out of communities the size of Mill Valley. Co-op service centers, grain and agricultural processing sites, small municipal utilities and rural industrial plants all accumulate transformers that nobody has ever offered a serious number on. Distance does not reduce our offer — we cover the freight and the rigging into Marin County the same way we would into a metro.
Lot buying and route consolidation
Where the economics genuinely improve for both of us is quantity. A pallet of pole-mount cans behind a service center, a row of retired padmounts along a fence line, a mixed pile of unknown units — aggregated, that is a trailer load worth real money, and we will send the equipment to load it.
Removal and Value
How a Mill Valley removal actually runs
The sequence is consistent. You send the nameplate and a few site photographs. We return a firm number, usually the same day. On acceptance we schedule against your window and send you insurance documentation and a bill of sale in advance. Our crew arrives in Mill Valley, cuts and caps conduit, breaks the unit loose from its pad or anchors, rigs and lifts it onto the trailer, and leaves the pad broom-clean with anchor bolts cut flush. Your funds go out before any of that happens — we do not load equipment we have not already paid for in full.
What sets your number in Mill Valley
Five things, in roughly this order: kVA rating, voltage class, winding material, fluid and condition. A 1000 kVA 12470–480V dead-front padmount with a legible nameplate and a sound tank is a resale asset and gets priced as one. The same rating with a cracked bushing and a weeping base weld is priced closer to materials. Copper windings beat aluminum materially. Non-PCB oil beats PCB-suspect oil, because the disposal cost is real. Documented test results — oil analysis, turns ratio, power factor — raise the number because they let a downstream buyer put the unit back in service instead of rebuilding it. None of that testing is required to sell to us, though — it is upside, never a precondition.
Equipment We Buy in Mill Valley
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.
