What RESA Power Solutions does
RESA Power Solutions is a North American provider of mission-critical electrical power system services, operating through more than 50 company-owned service centers across the United States and Canada. The company's offering spans four integrated pillars: (1) Power System Services including acceptance testing, preventative maintenance, relay calibration, infrared inspections, high-potential testing, engineering studies, and 24/7 emergency response; (2) Transformer Solutions covering oil testing, maintenance, retrofill, reinhibiting, remanufacturing, and new/used transformer sales; (3) Power Systems encompassing remanufactured and custom-built circuit breakers, motor control centers, switchgear, contactors, drives, and instrument transformers; and (4) Components and Specialty Distribution via the Relectric platform, which holds a broad inventory of new, legacy, and hard-to-find electrical equipment.
The company has grown primarily through an aggressive roll-up strategy, completing more than seventeen acquisitions since 2017 and scaling from 200 to over 800 employees and from 21 to 45 branches during Investcorp's 3.5-year ownership period. Under Kohlberg's majority ownership (April 2025), the cadence has continued with four acquisitions in 2025 and additional deals in early 2026, extending the Canadian footprint to five provinces (representing approximately 20% of revenue at the 2025 exit). RESA generates revenue through a mix of professional services (quote-based, often multi-year), hardware sales, equipment rentals, and buy/sell of used equipment, selling primarily to industrial, commercial, utility, renewable energy, government, and engineering/construction customers. The company maintains authorized OEM relationships with ABB, Eaton, Schneider Electric/Square D, and General Electric, and operates an ASTM-compliant Transformer Oil Testing Laboratory in Sacramento, California alongside the RESA Transformer Assessment Portal (TAP), which provides enrolled customers with 24/7 access to diagnostic data and condition-based maintenance recommendations.
