What RESA Power does
RESA Power is a private, Kohlberg-backed specialty electrical services platform operating as the largest national provider of mission-critical electrical power systems services in the United States, with an expanding footprint across five Canadian provinces. Its core offering is a comprehensive portfolio of services for mission-critical power infrastructure, including field services, engineering, installation, commissioning, instrumentation, cable evaluation, and power transformer services, augmented by in-house manufacturing of medium and high-voltage power transformers acquired through Société Générale d'Électrotechnique (SGE) and Power Asset Recovery Corporation (PARC).
The company serves three primary customer segments on a horizontal basis: data centers (with explicit emphasis on AI-driven data center demand), industrial and manufacturing facilities, and electrical utilities. Service delivery is direct to enterprise customers, with acquired regional subsidiaries (JA Tech, SGE, PARC) retained as regional hubs that bundle construction, engineering, testing, and transformer manufacturing within their geographies. Pricing and revenue mechanics are not publicly disclosed; the business model is consistent with project- and contract-based specialty industrial services, where recurring preventive maintenance and testing engagements are layered onto installation and commissioning work.
Growth is driven primarily by a programmatic, sponsor-financed acquisition strategy rather than organic expansion alone: the company executed eight acquisitions in 2024 alone (including Avatt and PARC) and continued into 2025–2026 with SGE (Quebec, January 2026) and JA Tech (Saskatchewan, March 2026). In April 2025 the company was sold under then-CEO Scott Harrison, who subsequently departed; ownership resides with private equity firm Kohlberg. Headcount is reported in the 251–500 range and revenue is not publicly disclosed.
