Clarke Energy Installs Renewable Biogas Technology at United States Wastewater Treatment Facility
Clarke Energy are proud to have been part of the opening ceremony for the combined heat and power (CHP) plant at the Benton Harbor-St. Joseph Wastewater Treatment Facility in Michigan, United States.
Resilience as a Competitive Advantage, Not a Cost
In today’s energy environment defined by grid congestion, extreme weather, rapid load growth, and accelerating transition requirements, resilience has become a strategic performance lever.
Clarke Energy Tunisia Celebrate Family Day Event
Clarke Energy Tunisia recently enjoyed a truly special day, centred around family, connection and shared moments 💛 As part of our Family Day, we were delighted to welcome the children of our colleagues. It was...
Why Data Center Power Systems Rarely Run at Full Load and Why it Matters
There’s a tendency in the data center industry to talk about power systems as if they operate at full load all the time. Most of the numbers we see; efficiency, output, performance, are based on...
How Data Centers Can Monetize Onsite Power Without Compromising Reliability
For most data center operators, onsite power generation is justified on one principle above all others: reliability. The moment that principle is perceived to be at risk, every other conversation, including cost and sustainability stops....
Rehlko and INNIO Enter Into Multi-Year Agreement to Support Global Data Center Demand
MILWAUKEE, Wis – April 9, 2026: Rehlko today announced that it has entered into a multi-year strategic engine framework agreement with INNIO Group, securing supply of approximately 1.25 gigawatts (GW) of gas engine capacity over...
Cormart Cuts Emissions, Stabilizes Operations with Gas-powered Strategy
Cormart Nigeria Limited, a member of Tropical General Investments (TGI) Group, has pivoted to gas as its primary power source, reducing emissions while shielding its operations from rising diesel costs and grid instability. The company...
Celebrating Women in Engineering on International Women’s Day
At Clarke Energy in France, we believe innovation is driven by diversity of talent, and particularly by the women who help move our industry forward. On the occasion of International Women’s Day, we were proud...
Keeping Data Alive: Thank You for Visiting Us at Data Center World
We have had a great few days at Data Center World London at ExCeL, joining colleagues from across Rehlko for one of the most important events in the data center calendar. The exhibition provided an...
Clarke Energy India Showcases Clean Energy Solutions at India Energy Week 2026
Clarke Energy India exhibited advanced clean‑energy solutions at India Energy Week 2026 in Goa. The team highlighted biogas upgrading, hydrogen‑ready Jenbacher engines, fast‑start backup solutions for data centers, and Waukesha engines engineered for demanding applications.
The New Reality of Hybrid Microgrid Controls for Data Centers
Hybrid microgrids are replacing traditional generator‑plus‑UPS models as data centers face AI-driven volatility and grid constraints. This article explains how modern microgrid controls work, why decentralized systems are more resilient, and how Clarke Energy deploys...
Prime Power vs. Base-Load Operation and Relevance to Data Centers
Prime power and base‑load power are frequently used interchangeably, but they describe different operating conditions for gas engines. Understanding these distinctions is critical for data‑center power design, resilience planning, and long‑duration bridging power.
Why Gas Engines Behave Differently Under Partial Load – and Why Data Centers Should Care
Modern data centers rarely operate at full load, making partial‑load engine behavior critical. Gas engines offer high efficiency, fast ramp rates, and strong integration with UPS and BESS systems—helping operators improve resilience, performance, and long‑term...
Engineering Data-Center Reliability with Prime-Running Gas Engines
Data-center availability targets from 99.9% to 99.999% require different architectures, not different engines. Prime‑running gas engines enable scalable reliability using modular redundancy, allowing operators to deliver hyperscale‑grade uptime with predictable performance.
