Power Partners

What Power Partners does

Power Partners is a US-based manufacturer of distribution transformers, founded in 1958 and operating a primary production facility at Athens, Georgia (200 Newton Bridge Road) under the corporate umbrella of ERMCO, Inc., whose headquarters sits at 2225 Industrial Road, Dyersburg, Tennessee. The company produces single-phase pad-mounted, single-phase pole-mounted, submersible, three-phase T-T, three-phase Triplex, and JUMBO distribution transformers in ratings from 5 to 1,000 kVA, all designed to meet ANSI, IEEE, NEMA, RUS, and DOE standards. Its customer base spans electric utilities, public power cooperatives, industrial and commercial operators (including oil-field, irrigation, and large motor-load applications), and renewable energy developers across North America, Central America, and the Caribbean.

The company's product portfolio is anchored by several proprietary technical features: an exclusive center-bolt cover design with self-venting/resealing and 15 kV dielectric insulation; the trademarked 2CEC two-coat cathodic electrodeposition paint process for corrosion resistance; the EZ Lift single-point eyebolt rated to 1,000 lbs and exceeding IEEE 5:1 safety; an internal low-voltage spark gap for surge protection; and a coordinated CSP protection package combining surge arresters, secondary breakers, and primary protective links. The Athens facility is ISO 9001:2015 certified by DQS, Inc. and has produced more than 9 million transformers cumulatively. The company operates a dedicated storm-response capability, committing to delivery in under 48 hours for emergency restoration after severe weather events.

Power Partners runs a direct, sales-led B2B go-to-market with named regional representatives for Utility East, Utility Midwest, Utility West, Industrial Construction, International, plus dedicated contacts for customer service, order entry, parts, storm response, and environmental compliance. Pricing is quote-based with no public list, reflecting a custom engineered-to-order hardware sales model. Ownership sits entirely within a private corporate structure: Power Partners is a wholly owned subsidiary of ERMCO, Inc., which is itself a wholly owned subsidiary of AECI. There is no disclosed venture, private equity, or public market participation.
