Powering Impact Card Row Our Businesses
Conscious Care™
Advanced life-cycle care and maintenance program for KD Series™ generators allows customers to reduce costs and emissions.
Alternative fuels for backup power
All Rehlko diesel engines and power generators are HVO fuel compatible which allows users to further decrease the carbon footprint across a generator's lifecycle.
Biogas upgrading
Rehlko offers tailored biogas upgrading systems that clean biogas (CH4 and CO2) into concentrated streams of renewable natural gas and carbon dioxide (bioCO2). RNG can be used to defossilize gas grids and act as a sustainable transportation fuel.
Combined heat and power
Combined heat, power and cooling (CCHP) systems anchored in gas engines, produce electricity, heat and or cooling. Utilization of onsite heat can double the efficiency of generation of power, reducing CO2 emissions per useful kW of energy.
Battery energy storage system (BESS)
Helps data center customers manage highly variable utility rate structures, load spikes with high-demand charges, and grid instability by balancing energy supply and demand behind-the-meter or as part of a hybrid system.
Power Impact Intelligence
The Rehlko Power Impact Intelligence is a strategic platform that can give data center operators direct, decision ready insight into the carbon impact of their power systems. Unlike static reports or disconnected data sources, it can deliver clear insight to support more informed infrastructure choices, including those that may reduce carbon emissions.

How Rehlko is working to build the foundation for a stronger, sustainable future.
- I believe our purpose, creating an energy resilient world for a better future, has never been more relevant. Electrification, digitalization, and economic growth are steadily increasing global energy demand and raising expectations for how power systems perform. These long-term trends are creating opportunity to rethink resilience, accelerate innovation, and build smarter, more adaptable energy infrastructure.”- Brian MelkaPresident and Chief Executive Officer
- Rehlko anchors its data center sustainability strategy in speed to power. By enabling efficient compute capacity through proven, fuel-flexible platforms, we help address near-term emissions requirements while preserving the ability to pursue future decarbonization pathways as regulatory, technological, and market conditions evolve. Our Structured Transition Model provides the strategic framework for executing this approach."- Francis PerrinChief Brand and Sustainability Officer
