Rehlko's Power Play: Consolidating to Fuel the Data Center Boom

MILWAUKEE, WI – June 16, 2026 – This week, global energy firm Rehlko announced that its UK acquisition, WB Power Services, has been fully absorbed into the parent company’s platform, shedding its former name to operate under the Rehlko banner. While corporate integrations and rebrands are commonplace, this move is far more than a simple change in letterhead. It represents the capstone of a meticulously planned strategy to build a dominant force in the UK and EMEA’s mission-critical power sector—a sector being stretched to its limits by the insatiable energy demands of the digital age.

This isn't just about launching a new service; it's about consolidating power, both literally and figuratively. By weaving WB Power Services’ deep-rooted UK engineering expertise into its global operating model, Rehlko is making a calculated bet on a future where energy resilience is not a luxury, but the bedrock of our increasingly digitized world.

A Strategic Consolidation

The final integration announced this month is the culmination of a process that began in August 2025 with Rehlko’s acquisition of The Wilmott Group, which included both WB Power Services (WBPS) and the acoustic product manufacturer Wiltech Acoustics. At the time, WBPS was a formidable player in its own right, reporting a turnover of nearly £150 million for the 2024 fiscal year. The acquisition was a clear signal of Rehlko’s intent to aggressively expand its end-to-end service capabilities.

By bringing WBPS fully into the fold, Rehlko is creating a unified platform that can manage the entire lifecycle of a critical power project—from system design and manufacturing to installation, commissioning, and decades of long-term service. This vertical integration, bolstered by the in-house manufacturing capabilities of Wiltech Acoustics, is a significant differentiator in a fragmented market.

“Bringing WB Power Services onto the Rehlko platform combines a strong UK engineering heritage, highly experienced teams, and long-standing customer relationships within a single operating model,” said Lenaik Andrieux, General Manager for EMEA, India and LATAM at Rehlko. “This strengthens how we deliver consistent, high-quality power solutions and lifecycle support for customers across the region.”

This sentiment is echoed by the company's leadership, who see the move as essential for meeting modern customer demands. “Aligning our UK operations under the Rehlko platform strengthens our operating model and expands our ability to serve customers in markets where reliability, scale, and consistency are critical,” noted Francis Perrin, Rehlko's Chief Brand and Sustainability Officer.

The Data Center Imperative

To understand the urgency behind Rehlko’s strategy, one must look at the staggering power demands of its target market: data centers. The proliferation of cloud computing and, more recently, the explosion in artificial intelligence are putting unprecedented strain on national power grids. Industry forecasts project that global data center electricity consumption will surge to 565 TWh in 2026, a 26% jump in a single year. By 2027, AI-optimized servers are expected to consume more power than all conventional servers combined.

In the UK, the situation is particularly acute. Data centers already consume nearly 6% of the nation's entire electricity supply, a figure that some analysts predict could quadruple by 2030. This has led to major grid constraints, with lead times for new high-capacity connections stretching for years, not months. For data center operators, where uptime is measured in fractions of a second and downtime can cost millions, relying solely on an aging grid is no longer a viable option.

This is the critical gap Rehlko is positioning itself to fill. The company's enhanced platform is designed specifically to provide the resilient, on-site power solutions—from backup generators to comprehensive energy systems—that data centers need to operate independently of grid fluctuations. By offering a standardized, scalable model across the UK and EMEA, Rehlko can provide hyperscale and colocation data center clients with the consistency and reliability they require to expand their footprint across the region.

From Local Legacy to Global Scale

For the thousands of customers in the UK who built long-term relationships with WB Power Services, a company founded in 1983 with deep community roots, a name change can be a source of anxiety. Rehlko appears keenly aware of this, emphasizing continuity as a cornerstone of the integration. The company has repeatedly assured clients that they will be served by the same experienced teams and that existing contracts, pricing, and service agreements will be honored.

The phased rebranding, which saw the company temporarily operate as “WBPS is now Rehlko,” was a deliberate choice to manage the transition carefully. The strategy aims to merge the best of both worlds: the trusted, local expertise and responsive service that defined WB Power Services, now supercharged by the global resources, R&D budget, and operational scale of Rehlko.

This integration is a pivotal moment not just for the acquired company, but for Rehlko itself. Having rebranded from the legacy Kohler Energy name in 2024 after being acquired by private equity firm Platinum Equity, Rehlko is on a mission to establish itself as the premier global name in energy resilience. This move shows it is willing to invest heavily in strategic assets that strengthen its core offering. By combining a legacy of UK engineering excellence with a forward-looking global vision, Rehlko is building a platform designed to power the critical infrastructure of tomorrow.
