About ERMCO Electric Research and Manufacturing Cooperative, Inc. (ERMCO) was founded in 1964 by three electric cooperatives with a mission to deliver reliable transformers to rural communities often overlooked by larger manufacturers. Headquartered in Dyersburg, Tennessee, the company quickly established itself as an innovator—becoming the first U.S. plant exclusively designed to produce single-phase pad-mounted transformers.
Over the decades, ERMCO has expanded its capabilities and footprint through facility growth, strategic acquisitions, and continued investment in innovation. ERMCO designs and manufactures a comprehensive portfolio of liquid-filled distribution transformers, including single-phase and three-phase pad-mounted and pole-mounted transformers, supported by a full range of components such as amorphous and silicon steel transformer cores, fuses, bushings, disconnect switches, and circuit breakers.
Today, nearly 3,500 employees across eight sites in North America support the company’s role as a leader in powering energy grids to meet evolving customer demand. Now more than ever, ERMCO is positioned to be the industry’s Most Valued Partner. About ERMCO’s Arizona Facility
