Rehlko and Liebherr Group marked a strategic capacity expansion at the Liebherr‑Components facility in Colmar, France, on June 2. The ceremony, attended by senior executives from both companies, underscored a shared vision of scaling resilient power solutions for the rapidly growing digital‑infrastructure ecosystem. The nearly 12,000 sq m extension will more than double the site’s production capacity for high‑performance generator engines that back data‑center power systems, a move aimed at meeting accelerating demand for reliable, zero‑downtime backup power. By reinforcing the Colmar plant’s ability to deliver engines at a faster pace, the partnership seeks to translate a growing backlog of orders into long‑term revenue and to capture additional market share in a sector that now underpins AI, cloud computing, and a host of critical online services.
Rehlko and Liebherr Partner on Strategic Capacity Expansion
The ceremony celebrated the completion of a near‑12,000 sq m expansion of the Colmar manufacturing site, which produces engines for generator sets used by data‑center operators. Once fully ramped, the plant’s output will exceed double its current level, providing a larger supply of resilient power solutions for hyperscale, colocation and other digital‑infrastructure customers.
The partnership, which began with the launch of the KD Series™ generator range in 2016, was deepened in May 2025 when the two companies agreed to further advance engine technology. Brian Melka, President and CEO of Rehlko, said the expansion “demonstrates our commitment to disciplined decision‑making and follow‑through, strengthening our ability to convert a growing backlog into long‑term revenue and capture additional market share in the data‑center sector.” Jens Krug, Managing Director of Liebherr‑Components Colmar SAS, added that the investment “creates the conditions to support future growth, drive innovation, and address evolving market needs.”
Both executives highlighted that the new space will not only increase volume but also integrate Liebherr’s high‑quality components—such as combustion‑engine control units, hydraulic systems, and electric drive technologies—directly into the production line. This integration is expected to improve overall generator reliability, extend lifecycle cost advantages for end users, and streamline the supply chain by co‑locating critical sub‑assemblies. The expansion is therefore positioned as a “structured industrial ramp‑up” that aligns with Rehlko’s broader strategy of scaling global industrial capacity to meet a structural market shift toward higher reliability standards in the data‑center arena.
Why the Expansion Matters for Energy Resilience
Data centers are increasingly the backbone of AI, cloud computing and other digital services, and operators are prioritizing zero‑downtime backup power. The expanded capacity directly supports this need by enabling faster delivery of high‑performance generator sets that can sustain critical loads when the grid is unavailable. For utilities and grid operators, a more robust supply of resilient power equipment can reduce the risk of widespread outages affecting data‑center clusters, which in turn helps maintain overall grid stability.
Rehlko’s broader portfolio—including Power Systems, Clarke Energy, Home Energy and Engines—positions the company to supply a range of backup solutions across industrial and residential sectors. By scaling production at Colmar, Rehlko can address a “structural market shift” toward higher reliability standards without relying on ad‑hoc procurement, thereby smoothing demand spikes that can strain supply chains.
Investment and Supply‑Chain Context
The expansion reflects a broader trend of industrial investors bolstering capacity to meet long‑term digital‑infrastructure demand. Liebherr, a family‑owned technology group with over 55,000 employees and €14 billion in combined revenues in 2025, is leveraging its diversified component expertise—ranging from combustion engines to electric drive systems—to support the project. The added 12,000 sq m facility not only increases engine output but also integrates Liebherr’s high‑quality components, potentially improving overall generator reliability and lifecycle cost for end users.
While the announcement cites “expected capacity expansion” and “accelerating digital backbone” demand, it also includes a forward‑looking statement noting that these expectations are subject to risks and uncertainties. No further financial terms, timelines for full ramp‑up, or detailed supply‑chain impacts were disclosed.
Key Takeaways
- The Colmar, France, expansion adds nearly 12,000 sq m of manufacturing space, allowing production capacity to more than double.
- Rehlko and Liebherr have partnered since 2016; the latest collaboration was expanded in May 2025 to advance engine technology for data‑center power needs.
- The upgrade targets growing demand for resilient, zero‑downtime backup power in hyperscale and colocation data‑center environments.
EnergyInsyte's Take
The capacity boost gives data‑center operators a more predictable source of high‑performance generators, which could ease procurement bottlenecks and support grid reliability. However, the timeline for reaching full output and the financial impact on Rehlko’s backlog remain uncertain, so executives should monitor production ramp‑up progress and any supply‑chain constraints that may arise.
