The Colmar site plays a central role in manufacturing engines used in high-performance generator sets supporting the data center ecosystem. Through its extension of nearly 12,000 square meters, Liebherr is strengthening industrial capabilities. Once fully ramped up, the expansion will enable the site’s production capacity to more than double, supporting increasing demand from the data center market.

This targeted expansion comes as demand for resilient, high-performance power solutions continues to accelerate at an unprecedented rate, driven by the growth of data centers, including hyperscale and colocation environments, powering AI, digital services, and cloud computing. With developers and operators increasingly prioritizing the rapid deployment of reliable backup power solutions to ensure uninterrupted operations, Rehlko is actively ramping its global industrial capacity and capabilities to support this structural market shift and long-term data center demand.

“This ceremony is an important milestone for our growth strategy as we scale our capacity to support the accelerating digital backbone,” said Brian Melka, President and Chief Executive Officer of Rehlko. “As data center demand continues to grow, customers are prioritizing resilient, scalable power solutions with zero downtime. This 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 while reinforcing our leadership in critical energy solutions.”

Jens Krug, Managing Director Liebherr-Components Colmar SAS added “This expansion reflects more than an investment in capacity — it demonstrates our long-term commitment to our partnership with Rehlko, to the Colmar site, and to the sustained growth of our industrial capabilities. As a family-owned company, we believe in building strong, trustworthy relationships that enable us to deliver innovative and reliable solutions for our customers worldwide. With this investment, we are creating the conditions to support future growth, drive innovation, and address evolving market needs.”

The relationship between Rehlko and Liebherr has steadily evolved since the launch of the KD Series™ generator range in 2016. Most recently, in May 2025, the two companies expanded their strategic collaboration to further advance engine technology and support growing demand. Over the past decade, the collaboration has grown in both scope and scale, supported by a shared focus on engineering excellence, performance, and long-term industrial alignment.

Rehlko remains focused on supporting the rapid evolution of the global data center market, with a comprehensive portfolio of power solutions. Backup power systems play a central role in ensuring continuity and reliability, as digital infrastructure becomes increasingly critical to global economic activity.
