Data center generator market set for rapid growth amid shift towards greener backup solutions and microgrids

The global data center generator market is projected to reach US$6.7 billion by 2028, driven by innovations in fuel technology, sustainability initiatives, and the expansion of microgrid infrastructure amid surging data demands.

The global market for data center generators is forecasted to experience substantial growth in the next decade, driven by the escalating demand for reliable and sustainable backup power solutions in data centers. According to a report by The Insight Partners, the market was valued at approximately US$4.7 billion in 2021 and is projected to reach nearly US$6.7 billion by 2028, reflecting a compound annual growth rate (CAGR) of 5.3%. This growth is underpinned by the critical role generators play in ensuring uninterrupted power supply, preventing costly outages that could lead to system downtime and data loss in increasingly digital economies.

Data centers, as foundational infrastructures for cloud computing, streaming services, healthcare, finance, and more, face intensifying pressure to maintain continuous operations amid rising data usage worldwide. Generators provide essential backup power during outages, securing operational stability. Technological innovations have transformed data center generators, prioritising fuel efficiency, faster startup, and emissions reduction. Integration of IoT sensors and AI-driven predictive maintenance systems are enabling operators to anticipate failures and optimise fuel use, enhancing reliability under fluctuating load conditions. Moreover, there is a notable shift toward hybrid power systems that combine traditional diesel generators with renewable energy and battery storage to bolster sustainability without compromising performance.

Sustainability is rapidly becoming a central theme within data center power infrastructure. Regulatory pressures and corporate environmental commitments encourage the adoption of advanced emission control technologies and cleaner fuel options such as natural gas and biofuels. Additionally, the increased integration of renewable sources like solar and wind energy within power supply chains elevates the role of generators as vital fallback solutions during supply fluctuations. This dual focus on reliability and greener operation aligns with global efforts to reduce the carbon footprint of expanding data center networks.

Investment opportunities in this sector could exceed US$3 billion by 2028, with innovation in alternative fuels gaining traction. Hydrotreated Vegetable Oil (HVO) fuel, for example, is increasingly adopted by major players including AWS and Kohler in Europe, reflecting a move toward greener backup power solutions. While diesel generators remain predominant, there is accelerating interest in gas-powered, fuel cell, and eco-diesel generators that support zero-carbon emission goals. Large hyperscale data centers are also investing in higher-capacity generators, often within the 1.5-3 MW range or above, to meet their extensive power needs.

In the United States, the challenge of meeting surging electricity demand from data centers has prompted both private and public sectors to explore advanced energy solutions. Power requirements for data centers, especially those supporting artificial intelligence (AI) workloads, are forecasted to nearly triple in the next few years. Chevron, for instance, is progressing with plans to develop data centers alongside dedicated natural gas-powered electricity supply facilities, aiming for operational readiness by 2027-2028. These sites may also incorporate carbon capture technologies and renewables to address environmental objectives.

Microgrids are emerging as a complementary solution to traditional backup generators, expanding rapidly across the US to enhance power reliability for data centres. These localized energy systems can operate independently of the main grid, offering resilience and supporting sustainability goals. With projected capacity growth from 4.4 GW in 2022 to 10 GW by 2025, microgrids benefit from government funding and state incentives in regions like California, Texas, and Colorado. Major technology companies are investing in this infrastructure to circumvent limitations of existing grid connections and provide flexible, clean energy services.

However, integrating the surging power needs of data centers into national grids presents significant challenges. The US Department of Energy predicts that data centers could consume up to 12% of the country’s electricity by 2028, compared to over 4% currently, primarily driven by AI and GPU-accelerated servers. This demand strains existing grid infrastructure, particularly in power hubs such as Virginia and Texas, leading to delays in new data center projects and requiring utilities to adapt through rate adjustments and enhanced market mechanisms. Tech firms are also innovating with energy-efficient cooling, workload flexibility, and co-location strategies with power generation to optimise grid interaction.

Looking further ahead, nuclear power is poised for a renaissance as a key energy source for data centers, given its reliability and zero-carbon attributes. Analysts at Wood Mackenzie forecast a 27% increase in US nuclear generation between 2035 and 2060, supported by substantial government investments and participation from leading tech companies. While advanced nuclear technologies like small modular reactors hold promise for addressing future electricity demands, they face developmental and regulatory hurdles. Globally, data center electricity consumption is expected to surge from 700 TWh in 2025 to around 3,500 TWh by 2050, underscoring the scale of energy transition needed, with nuclear expected to play a critical role alongside renewables and other innovations.

In summary, the data center generator market is evolving rapidly, driven by the dual imperatives of meeting burgeoning power demand and minimising environmental impact. Innovations in fuel technology, hybrid power systems, and integration with emerging energy solutions like microgrids are reshaping backup power architectures. Meanwhile, broader energy strategy shifts, including advanced natural gas facilities and the potential future expansion of nuclear power, illustrate the complex landscape data centers navigate to ensure resilience and sustainability in a data-driven future.
