Data Center Power: Infrastructure, Challenges, and the Path to Efficiency
Data center power refers to the systems, strategies, and technologies used to supply, manage, and optimize electrical energy for data centers—the facilities that support cloud computing, enterprise IT, artificial intelligence, and digital services. As data volumes and computing intensity increase, power has become one of the most critical design and operational considerations for modern data centers, influencing reliability, cost, sustainability, and scalability.
At its core, data center power infrastructure includes utility connections, substations, switchgear, transformers, uninterruptible power supplies (UPS), backup generators, power distribution units (PDUs), and server-level power management components. Electricity typically enters a data center from the grid at high voltage, is stepped down through transformers, conditioned through UPS systems, and distributed across racks and servers. Each layer is designed to minimize power interruptions and ensure consistent voltage and frequency, as even brief outages can lead to service disruption…
