Emergency Power Generator Market to Reach USD 25.05 Billion by 2035 at 6.2% CAGR as Data Center Construction Raises Demand for On-Site Standby Power

The global Emergency Power Generator market size was USD 13.70 Billion in 2025 and is expected to reach USD 25.05 Billion by 2035, registering a revenue CAGR of 6.2% during the forecast period, according to the latest analysis by Emergen Research.

MARKET SYNOPSIS

The global Emergency Power Generator market size was USD 13.70 Billion in 2025 and is expected to register a revenue CAGR of 6.2% during the forecast period. Data center construction is the first structural driver, because a data center cannot accept a break in supply and owners install enough generator capacity to carry the full site load. The International Energy Agency reported that data centre electricity demand rose 17% in 2025. Longer and more frequent grid outages add demand from homes, hospitals and factories.

The market entered the forecast period with strong supplier order books. Cummins reported Power Systems sales of USD 7.46 Billion in 2025, up from USD 6.41 Billion in 2024, and its chief executive officer cited demand for data center backup power. For instance, in June 2026, Cummins, United States, announced an agreement to supply natural gas generator sets for a West Texas high-performance computing data center, with deliveries scheduled over five years beginning in 2026. These are some of the key factors driving revenue growth of the market.

However, battery energy storage is replacing generators at sites that need cover for short outages, and disruption of Gulf energy and shipping supply has raised fuel, steel and freight costs for makers. The US Energy Information Administration reported that US battery storage capacity reached nearly 52 GW by June 2026. These factors substantially limit Emergency Power Generator market growth over the forecast period.

SEGMENT HIGHLIGHTS

Based on fuel type, the global Emergency Power Generator market is segmented into diesel, gas and others. The diesel segment held the largest share of 58.0% in 2025. A diesel emergency generator starts and takes full load within about ten seconds of a grid failure. It leads because diesel can be stored on site for days without a pipeline connection, and codes for hospitals and data centers were written around on-site fuel storage. The gas segment is expected to register a rapid revenue growth rate in the global market over the forecast period.

Based on end use, the global Emergency Power Generator market is segmented into commercial, residential, industrial, data centers, healthcare and others. The commercial segment held the largest share of 26.0% in 2025. Commercial use covers offices, shops, hotels, schools and public buildings, where a power failure stops trading or breaks a life-safety system. The segment leads because building codes require emergency power for life-safety loads in most mid-rise and high-rise buildings, so each new building buys at least one set. The data centers segment is expected to register a rapid revenue growth rate in the global market over the forecast period.

REGIONAL HIGHLIGHTS

Based on regional analysis, the Emergency Power Generator market in North America accounted for largest revenue share in 2025. Extreme-weather outages keep demand high, and the US Energy Information Administration reported that the average US electricity customer faced 11 hours of interruptions in 2024, nearly double the annual average of the previous decade. Generac reported commercial and industrial product sales of USD 1.46 Billion in 2025, up 5% from 2024. The United States-Iran confrontation since late February 2026 raised diesel, steel and freight costs for regional makers.

The market in Asia Pacific is expected to register a 7.0% CAGR through 2035, after holding 28.0% of global revenue in 2025. India's Ministry of Power reported an all-time peak demand of 256.1 GW on 25 April 2026, which adds buildings, data centers and tower sites that need local backup. The United States-Iran confrontation raised fuel and freight cost uncertainty for regional buyers.

The market in Middle East & Africa is expected to register the fastest CAGR of 7.6% through 2035. Eskom reported on 23 February 2026 that South Africa had gone about 280 days without load shedding. The United States-Iran confrontation disrupted sea routes into Gulf ports, because the Strait of Hormuz carries around one quarter of global seaborne oil trade, according to UNCTAD.
