Rehlko has been developing power and energy resilience solutions since 1920, when it introduced the Kohler Automatic Power & Light power plant. Operating as an independent enterprise, the company now provides distributed energy solutions across five business units: Power Systems, Engines, Uninterruptible Power, Home Energy, and Clarke Energy. Its technical expertise spans energy resilience, distributed energy systems, power systems engineering, engines and powertrain technologies, uninterruptible power systems (UPS), and the engineering, installation and maintenance of critical power infrastructure.
The company operates more than 100 locations across the Americas, Asia, Europe, the Middle East, and Africa. Its customer base spans data centres, hospitals, residential properties, commercial facilities, industrial energy systems, and essential infrastructure. Rehlko positions itself as a global leader in energy resilience, with historical projects including power supplies for Admiral Byrd's South Pole expedition, Hollywood studios, and the Hoover Dam.
As an independent enterprise, Rehlko is structured around delivering comprehensive energy solutions tailored to different market segments, from residential homes to mission-critical industrial applications. The company's approach emphasises engineering, installation and ongoing maintenance of power solutions designed to ensure continuity in environments where power interruption is not an option.
