Incorporated in 1964, ERMCO began transformer production in January 1972 with 30 employees producing 30 units weekly in a 32,000 square foot facility. It was the first plant in the nation built solely by rural electrics to make single-phase padmount transformers new to the market.
ERMCO was also one of the first transformer manufacturers to substitute aluminum foil for copper wire in transformer coils due to the expense of copper and government regulations.
The eighties & nineties were decades of abundant expansion, diversification, and growth for the company. ERMCO expanded its business into three-phase padmount transformers and purchased a building/property adjacent to the single-phase facility to produce the three-phase transformers.
The company diversified its product line with the purchase of General Electric Transformer Components Company in Greeneville, TN. The company was renamed ERMCO Components, Inc. (ECI).
In 2017, ERMCO acquired GridBridge, our Advanced Learning Center located in Raleigh, NC. Gridbridge develops state-of-the-art technology combining hardware, software, and data management into cutting-edge solutions for utility partners.
As of 2021, the ERMCO campus in Dyersburg, Tennessee, has four facilities and 1.5-million square feet of production space spanning 150 acres and is the largest employer in Dyersburg and employs 1450+ dedicated people.

Construction began on the 32,000 sq-ft, $350,000 Single Phase facility.
After installing $200,000 worth of equipment, production of core and coils began with a staff of 30 employees.
The plant expanded to 145,000 square feet during the 80s, with additions in 1982 and 1989. The 1989 expansion included a 45,000 square-foot tank manufacturing facility which allowed ERMCO to manufacture its transformer tanks.
The '90s saw rapid growth, expansion, and diversification for the company. ERMCO became the 4th largest manufacturer of single-phase transformers. The company then employed 450 people and manufactured over 150,000 units annually. Computerized business systems were introduced, and designing transformers became digital.
ERMCO acquired the General Electric Transformer Component Company in Greeneville, TN and renamed it ERMCO Components, Inc. (ECI).
ERMCO purchased an existing building adjacent to the Single Phase plant and broadened its product line to include three-phase transformers for commercial and industrial applications. The first three-phase padmount unit was built in 2000 and installed next to the Dyer County Courthouse.
ERMCO purchased a 200,000 square feet plant - located in a former Caterpillar facility in Dyersburg - expanding manufacturing operations and creating an additional 150 jobs.
ERMCO acquired Pioneer Transformers, Power Partners, Jefferson Electric, and V&F Transformer — formerly Spire Power Solutions companies — and brought them under the ERMCO umbrella.
The expansion allowed ERMCO to expand its capacity and extend its product offerings into the renewable energy and data center markets.
