Transformer buyers in San Antonio & South Texas
We buy single transformers and whole lots, any brand, from 10 kVA pole-mount units to large MVA substation and power transformers. kVA and MVA describe a transformer's power capacity, with one MVA equal to 1,000 kVA. Equipment can be new in its crate, used and working, retired from service or failed.
Our base of operations is 6402 McGrew St, Houston, TX 77087. We coordinate trucking and pickup statewide, including San Antonio, New Braunfels, Seguin, Laredo and oilfield locations south of the city. You do not need to bring the equipment to Houston to start the offer process.
For a project within the city, see our San Antonio transformer buying page. For a regional lot, identify each pickup location and tell us whether the transformers are still installed, disconnected or stored.

Facility upgrades and surplus around San Antonio
San Antonio's manufacturing base, military facilities including Joint Base San Antonio, and growing west-side data center cluster create several situations where transformers can become available. A capacity upgrade can leave a working unit behind. A redesign can make purchased equipment unnecessary, while a facility closure can produce a mixed lot of installed and spare units.
We buy transformers in San Antonio & South Texas from sellers handling these changes, including facility owners, project managers and electrical contractors. Describe whether your equipment came from an operating system, an unused project purchase or a replacement after a failure. That background helps distinguish an unused spare from a unit with an unknown service history.
If several departments or sites contributed to the lot, label the photos by unit. Clear identification helps keep nameplate data, condition notes and quantities matched throughout the evaluation.

Growth corridors, border facilities and oilfield projects
Fast growth along I-35 and I-10 through New Braunfels and Seguin can leave surplus after construction changes, service upgrades or equipment replacements. Developers and contractors may have unused transformers from revised plans, while established facilities may retire equipment when loads change. Our pages for selling transformers in New Braunfels and transformer sales in Seguin cover those locations.
Farther south, I-35 connects to Laredo, the busiest US land port by trade value. Warehouses, distribution properties and border-related facilities can have transformers available after electrical upgrades or redevelopment. Include the facility address when submitting equipment from Laredo and nearby project sites.
Eagle Ford Shale oil and gas activity south of San Antonio presents another setting for surplus and retired equipment. For an oilfield location, send the site name, access directions and any gate restrictions rather than relying only on a mailing address.
Padmount, dry-type and substation equipment
Three-phase padmount transformers serve larger commercial and industrial loads; single-phase padmount units serve smaller loads. Both are enclosed outdoor transformers mounted at ground level. For padmount transformer offers, show the enclosure, nameplate and accessible connection compartments without opening energized equipment.
Unit substations combine a transformer with associated switching or distribution equipment. Tell us which sections are included and whether they remain assembled. Dry-type transformers use air and solid insulation rather than insulating liquid; our dry-type buying page covers equipment commonly installed inside buildings.
We also buy substation transformers and new surplus transformers, including crated units that never entered service. Larger equipment may have separate radiators, fans, bushings or other accessories. Photograph those items and explain what is included so the offer covers the equipment actually available.
Details that help us evaluate your transformer
To sell transformers in San Antonio & South Texas, send clear photos and a short equipment summary. The nameplate should show capacity, primary and secondary voltage—the incoming and outgoing voltage—and other readable ratings. Impedance, the transformer's opposition to current flow, is another useful nameplate detail.
Overall photos should show the enclosure or tank, visible damage and storage conditions. For failed units, describe the known failure rather than guessing at the cause. If you have service records, test reports or an inventory sheet, include them with the photos.
- List the quantity and identify each unit when a lot contains different capacities or voltage ratings.
- Give the equipment's physical location, including whether it is indoors, outdoors, on a pad or already staged for loading.
- State whether each transformer is new surplus, used and working, retired or failed, and note missing parts.
- Identify loose accessories and provide crate or packaging photos for unused equipment.
Pickup planning across South Texas
We plan the trucking and loading with you ahead of pickup. Depending on the origin, regional trucking may use I-10, I-35, I-37, I-410, Loop 1604, SH 130 or US-59. The actual pickup plan depends on equipment dimensions, weight, site access and loading arrangements, not just the nearest highway.
Before pickup, the seller or a qualified electrical contractor hired by the seller must de-energize and disconnect the unit. Tell us about loading access, overhead obstructions, narrow gates, dock availability and site scheduling requirements. Large transformers may need a different loading arrangement than palletized dry-type units or small padmounts.
Use our Texas transformer shipping guide to organize the transport information. Price, payment terms and pickup details are agreed in writing before anything is loaded, so both sides know which units are included and how load-out will proceed.
