Whitepaper: Powering the Next Generation of Data Centers Starts with Rethinking Power Distribution
May 26, 2026
Artificial intelligence (AI) computing is redefining data centers, and the future of this ecosystem is being reshaped right now. Extreme power densities, grid constraints and emerging architectures such as DC power and on-site generation demand a fundamentally different approach to safety and reliability, with UL Solutions at the forefront defining what comes next.
UL Solutions helps original equipment manufacturers (OEMs), suppliers, operators and integrators build with confidence, scale and operate smarter, and integrate without compromise through comprehensive testing, inspection, certification and advisory services that evaluate complex power systems, mitigate risk and enable more resilient, future-ready infrastructure.
Navigating safety in a changing data center power landscape
Designing power systems for modern data centers requires navigating a complex landscape of more than 55 UL Standards that apply to electrical infrastructure, equipment and components across the facility. As operators explore DC architectures to support rising power densities, new safety considerations emerge. DC systems behave differently from traditional AC systems, and phenomena such as DC arc flash remain less familiar and more difficult to predict and mitigate.
Addressing these evolving risks requires deep standards expertise and rigorous testing to help evaluate systems and components’ safety, performance and compliance.
