The global data center generators market is projected to expand from USD 8.57 billion in 2026 to USD 9.79 billion by 2031, according to a new Research and Markets report, as operators invest in backup power to protect uptime amid grid failures, extreme weather and rising AI-driven electricity demand. The report says bi-fuel generators are expected to post the fastest growth over the forecast period because they combine diesel and natural gas to improve fuel flexibility, lower emissions and support resilience during extended outages. Systems rated above 3 MW are expected to hold the largest market share through 2031, reflecting demand from hyperscale, colocation and enterprise data centers running AI training, cloud computing and high-performance computing workloads. North America is expected to remain the largest market, while Asia Pacific is projected to grow the fastest on digital infrastructure investment, cloud adoption and expanding hyperscale and colocation capacity.
