AI is driving a surge in data center electricity demand. That's why operators are increasingly dependent on backup generators and other technologies that can reduce energy use and ease pressure on power grids.

Artificial intelligence is driving a sharp increase in electricity demand from data centers, placing growing pressure on power grids around the world and increasing the need for reliable backup power.

Companies like Rolls-Royce Power Systems provide generator systems that help keep data centers operating during power outages. But as AI workloads continue to expand, data center electricity consumption is projected to rise significantly in the coming years.

To improve efficiency and help meet growing energy needs, operators are investing in technologies such as liquid cooling, flexible power management and waste heat recovery. These approaches can lower energy use, improve efficiency and support the expansion of AI infrastructure.
