The Data Center Frontier Show

This podcast explores the rapidly evolving thermal and water challenges facing today’s data centers as AI workloads push rack densities to unprecedented levels. The discussion highlights the risks and opportunities tied to liquid cooling—from pre-commissioning practices and real-time monitoring to system integration and water stewardship. Ecolab’s innovative approaches to thermal management can not only solve operational constraints but also deliver competitive advantage by improving efficiency, reducing resource consumption, and strengthening sustainability commitments.

Join Bill Tierney of The Data Center Construction Alliance, as he discusses some of the emerging challenges facing data center development today. Topics will include how increasing collaboration between OEMs, owners, contractors, and sub-contractors is leading to some exciting and innovative solutions in the design and construction of data centers. He will also share some examples of how collaboration has led to new ideas and methodologies in the field. 

AI networks are driving dramatic changes in data center design, especially around power, cooling, and connectivity. Modern GPU-powered AI data centers require far more energy and generate much more heat than traditional CPU-based setups, pushing cabinets to new power densities and necessitating advanced cooling solutions like liquid direct-to-chip cooling. These environments also demand significantly more fiber cabling to handle increased data flows, with deeper cabinets and complex layouts that make traditional rear-access cabling impractical.

Key discussion points include: What it means to be a solutions provider in a high-demand, high-stakes environment How Rehlko engineers collaborate to solve challenges before they impact project delivery Why deep application knowledge is essential to right-sizing designs and avoiding over- or under-specification How industry collaboration is key to unlocking new energy strategies, sourcing approaches, and long-term resilience For data center leaders navigating rising demand and tighter constraints, this episode highlights how Rehlko’s engineering-first, collaboration-driven approach is helping customers stay ahead, delivering smarter, more resilient infrastructure for the AI-powered future.

As artificial intelligence (AI) reshapes the data center landscape, power resiliency is being tested like never before. With enormous new facilities coming online and operators exploring alternatives to diesel, the backup power market is at an inflection point. In this episode of the Data Center Frontier Show, we sit down with Ricardo Navarro, Vice President of Global Solutions at Generac Power Systems, to discuss how the company is positioning itself as a major player in the data center ecosystem. Diesel Still Reigns — For Now Navarro begins by addressing the foundational question: why diesel remains the primary backup power choice for hyperscale and AI workloads. The answer, he explains, comes down to density, responsiveness, and reliability. Diesel engines respond instantly to the fluctuating loads that are common in AI training clusters, and fuel can be stored directly on-site. While natural gas is gaining traction as a bridging and utility-support solution, true redundancy requires dual pipelines — a level of infrastructure not yet common in data center deployments. That said, Navarro is clear that the story doesn’t end with diesel. He sees a future where natural gas, paired with batteries, becomes a cost-effective and environmentally attractive option. Hybrid systems, combined with demand response and grid participation programs, could give operators new tools for balancing reliability and sustainability. “Natural gas might not be the right solution right now, but definitely it will be in the future,” Navarro notes. Scaling Fast to Meet Hyperscaler Demands The conversation also explores how hyperscalers are shaping requirements. With campuses needing hundreds of generators, customers are asking not just about product performance, but about scale, lead times, and support. Generac is addressing that demand by delivering open sets in as little as 30 to 35 weeks — about a third of the wait time from traditional OEMs. That speed-to-deployment advantage has driven significant new interest in Generac across the hyperscale sector. From Generators to Energy Technology Equally important is Generac’s shift toward digital tools and predictive services. Over the past decade, the company has invested in acquisitions such as Deep Sea Electronics, Blue Pillar, and Off Grid Energy, expanding its expertise in controls, telemetry, and microgrid integration. Today, Generac is layering advanced sensors, machine learning, and AI-driven analytics onto its equipment fleet, enabling predictive failure detection, condition-based maintenance, and smarter load orchestration. This evolution, Navarro explains, represents Generac’s transformation “from being just a generator manufacturer to being an energy technology company.” What’s Next for Generac Looking ahead, the company is putting real capital behind its ambitions. Generac recently completed a $130 million facility in Beaver Dam, Wisconsin, designed to expand production capacity and meet surging demand from data center customers. With firm domestic and international orders already in place, Navarro says the company is determined “to be in the driver’s seat” as AI accelerates the need for scalable, resilient, and flexible backup power. For data center leaders, this episode provides a clear look into how backup power strategies are evolving — and how one of the industry’s largest players is preparing for the next wave of energy and infrastructure challenges.
