Kohler Power

What Kohler Power does

Kohler Power, now operating as Rehlko under legal entity Discovery Energy, LLC, manufactures and markets power generation and distribution equipment for industrial, residential, marine, and mobile applications. The portfolio spans industrial energy systems (large-frame generators, uninterruptible power supplies, and complex microgrids), home backup generators commercial-graded for residential resilience, and powertrain technologies covering combustion engines through hybrid and electrified propulsion for OEMs. It pursues four primary business segments — Industrial Energy Systems, Powertrain Technologies, Home Energy, and Data Center Power Solutions (the last newly launched to capture hyperscale, colocation, and enterprise/edge demand driven by AI infrastructure buildouts). Underlying technology is rooted in multi-fuel generation (diesel, natural gas, LNG), UPS and power distribution, and, since the January 2022 acquisition of Heila Technologies, distributed energy resource (DER) and microgrid orchestration software that integrates on-site generation with grid and storage assets. The company is a global top-tier player repeatedly cited alongside Caterpillar, Cummins, ABB, Siemens, Rolls-Royce, and Wärtsilä in the $45.9 billion global generator market and the $10.49 billion data center generator segment. Its core technology differentiator lies in end-to-end system integration — enclosures, distribution, and controls — rather than commoditized genset hardware alone.

The unit makes money primarily through hardware sales of generators, UPS systems, and powertrain components to enterprise and industrial buyers (data centers, hospitals, industrial plants), complemented by residential backup generator sales to homeowners and SMBs. Go-to-market is dual-pronged: a direct enterprise field-sales motion anchored by a 1-800 support line for customized industrial quotations, layered with a multi-brand channel network that includes Clarke Energy for global multi-application generator distribution, Kohler Home Energy for residential products, Uninterruptible Power for UK/regional UPS distribution, and regional power systems/engines portals. Pricing is quote-based and not publicly disclosed. Rehlko is a wholly owned subsidiary of Kohler Co., the privately held diversified manufacturer founded in 1873 and headquartered in Kohler, Wisconsin; the 2025 rebrand from Kohler Energy to Rehlko reflects an organizational separation to position the energy business for growth and, potentially, future strategic optionality, without changing ultimate ownership.

Customer concentration is enterprise-skewed across mission-critical infrastructure (data centers, hospitals, industrial facilities) where contract values are large but buyer switching costs are high; the residential segment is distributed through dealers such as Brook Field Service Generators. Reported entity-level headcount of 51–100 in firmographic inputs appears inconsistent with industrial-OEM scale and most likely reflects a disclosure scope narrower than consolidated Rehlko operations. Specific revenue, ARR, or segment financial disclosure is not publicly available for Discovery Energy, LLC.
