What Emerald Transformer does
Emerald Transformer is a US-based, privately held industrial services company founded in the 1970s and headquartered in McKinney, Texas. It positions itself as the largest transformer service company in the United States, operating eight full-service manufacturing and service facilities across the country (McKinney TX headquarters; Waco TX; Phoenix AZ; Los Angeles CA; Coffeyville KS; Nabb IN; Twinsburg OH; DeFuniak Springs FL; Tucker GA; Lexington MS) with a fleet of 80+ drivers for nationwide logistics.
The company's core offering is a vertically integrated, cradle-to-grave service stack for oil-filled electrical equipment: refurbishment and sale of polemount and padmount transformers (3–10,000 KVA range), voltage regulators, and reclosers backed by a 3-year (with optional 5-year) warranty; tiered transformer repair and remanufacturing (minor check, recondition, rewind); field technical services including substation decommissioning (100+ projects per year); transformer oil laboratory analysis; oil re-refining and PCB removal; recycling of 300,000+ units per year at a 98% rate; PCB disposal through five EPA-permitted commercial storage facilities and two Scrap Metal Recovery Ovens; parts distribution across 1,500+ SKUs; and cradle-to-grave record keeping. Authorized warranty service partnerships with OEMs such as G&W Electric extend the company's reach into recloser field service across the Southeastern US.
Commercially, Emerald sells exclusively B2B via direct field sales, phone, email, and online quote forms to investor-owned utilities, electric cooperatives, municipalities, and commercial/industrial customers; the operating model is enterprise, quote-based, with refurbished equipment offered at 30–70% cost savings versus new units and ancillary services billed on a project basis. The company employs 450+ people, has 50+ years of operating history, and is led by CEO Stuart Prior (formerly of ThyssenKrupp Elevator), COO Daniel Hall, CFO Jason Weiland, and CHRO Meredith Allred. No external funding rounds or private-equity ownership are disclosed.
