Rehlko has taken a big step forward in addressing the balance needed between providing adequate data center capacity and doing so sustainably with its newly released 2026 Powering Impact Report. The global energy resilience leader published its second report, detailing how they’ve embedded sustainability into resilient power solutions for data centers. 

To meet the needs data centers have for reliable and resilient power amid grid constraints, the company aims to position sustainability as a practical enabler that can inform how power systems are specified, designed, and optimized over time based on a variety of factors including location, fuel availability, regulatory conditions, and customer priorities.

How Has Rehlko Increased Sustainability for Data Centers?

The report highlights how Rehlko’s portfolio supports data centers under tight timelines with the ability to support the modular integration of technologies, such as battery energy storage systems (BESS), combined cooling, heat, and power (CCHP), advanced controls, and compatibility with alternative fuels, where appropriate.

The report outlines how Rehlko leads by example, improving efficiency of its own operations. Highlights include:

• A 19.6% reduction in Scope 1 and 2 greenhouse gas emissions compared to a 2023 baseline, based on defined methodologies
• 81.2% of operational waste diverted from landfills

Additional Rehlko Tools

Rehlko also recently launched the Rehlko Power Impact Intelligence strategic platform, which includes the Rehlko Backup Power | EPD Carbon Calculator. The tool provides access to verified Environmental Product Declaration (EPD) data, enabling customers to evaluate the embodied carbon of backup power systems at a product level. It helps customers make informed infrastructure choices, including those that may reduce carbon emissions.

“Data center customers are navigating a more complex set of power decisions than ever before. Our role is to help deliver systems that are reliable when and where they’re needed, while working to improve the quality of information customers use to evaluate energy choices. The Powering Impact Report reflects how we’re integrating sustainability insight directly into engineering, tools, and execution.” – Brian Melka, President and Chief Executive Officer of Rehlko.
