Surging Gas Turbine Demand Fueled by Data Center, AI Growth

Demand for gas turbines is accelerating in 2025 as rapid data center expansion and AI growth place increasing strain on power grids worldwide. Utilities, independent power producers, and large technology companies are turning to gas-fired generation to meet rising electricity needs driven by cloud computing, AI training, and high-density digital workloads.

Industry analysts say the pace of data center development, combined with grid congestion and lengthy interconnection queues for renewable projects, has elevated gas turbines as a near-term solution for reliable, dispatchable power. While long-term decarbonization goals remain central to energy planning, immediate capacity and resiliency needs are reshaping investment decisions across the power generation sector.

Data Centers Drive Load Growth

Electricity demand from data centers has emerged as one of the fastest-growing sources of load on the grid. AI applications, particularly large language models and generative AI systems, require substantial computing power and operate continuously, consuming significantly more electricity per facility than traditional data centers.

Hyperscale data centers can require hundreds of megawatts of power, often concentrated in regions not designed to support that level of demand. Utilities report that proposed data center projects are arriving faster than transmission upgrades or new generation can be completed, creating short-term supply gaps.

Gas turbines offer a practical response. Compared with other generation technologies, they can be installed more quickly, sited flexibly, and operated at variable loads. Aeroderivative turbines and advanced heavy-duty models are especially attractive because they can ramp rapidly, helping balance sudden changes in demand associated with data center operations.

“Aeroderivative gas turbines are popular with AI data centers because of their speed, flexibility, and reliability in providing on-site power,” said Carter Palmer of Forecast International. “As AI workloads demand massive amounts of electricity, traditional grid infrastructure often can’t keep up with the rapid growth of these facilities, leading to long delays for new grid connections. Aeroderivative turbines can be installed quickly, and their modular design allows for easy scalability as a data center’s power needs grow.”

A Bridge for Reliability

In 2025, gas turbines are frequently described as a bridge technology, addressing immediate power needs while supporting broader energy transition objectives. Combined-cycle gas turbine plants provide high efficiency and lower emissions than coal-fired generation, while simple-cycle units deliver fast-start capability critical for grid stability.

For data center operators, reliability is paramount. Even brief outages can disrupt operations and lead to significant financial losses. As a result, some operators are pursuing dedicated or on-site generation to supplement grid power. Gas turbines are increasingly deployed in behind-the-meter applications or as part of hybrid systems that combine gas generation, battery storage, and renewable energy.

OEMs report growing orders for new turbines as well as upgrades and life extensions for existing fleets. In many cases, operators are refurbishing older units or increasing output through uprates, allowing capacity to be added more quickly than through new construction alone.

AI and Power Quality

AI-driven computing places unique demands on power systems. Training and running AI models requires stable voltage and frequency, placing additional stress on transmission and distribution networks. Grid operators are responding by prioritizing flexible generation assets that can maintain power quality during rapid load changes.

Gas turbines play a key role in that strategy. Fast-start units can reach full output in minutes, providing frequency regulation and reserve capacity. Modern digital controls and monitoring systems help operators optimize performance and availability, improving reliability for data centers that operate around the clock.

The growth of AI has also intensified interest in redundancy. Many data center projects include multiple layers of backup power, ranging from uninterruptible power supplies to on-site generation. Gas turbines are increasingly used alongside or in place of diesel generators, offering lower emissions profiles while maintaining high reliability.

Supply Chain and Workforce Effects

The surge in demand is affecting gas turbine manufacturing and service markets. OEMs are expanding production capacity, while service providers report increased demand for maintenance, parts, and lifecycle support. Lead times for certain turbine models and critical components have lengthened as order backlogs grow.

“The growth in renewable energy, with its intermittent availability, has created a large demand for dispatchable energy in the form of gas turbine power plants, both simple and combined cycle,” said Klaus Brun of Ebara Elliott Energy and Rainer Kurz of RKSBenergy. “The large driver for new power generation has been fostered by the demand for new data centers, with a surge in AI-related, Bitcoin-related, and general data processing.”

Workforce constraints remain a challenge. As experienced technicians retire, companies are investing in digital diagnostics, remote monitoring, and predictive maintenance to keep fleets operating reliably. These tools allow smaller teams to manage larger portfolios of assets, a growing requirement as generation capacity expands to meet data center demand.

Suppliers are also adapting turbine designs to reflect changing customer expectations. Fuel flexibility, efficiency improvements, and readiness for future low-carbon fuels are increasingly part of procurement discussions, particularly for assets expected to operate for decades.

Permitting and Policy Pressures

Regulatory and permitting hurdles continue to shape where and how gas turbines are deployed. In some regions, permitting timelines for new power plants remain lengthy, even as demand accelerates. Transmission constraints and interconnection delays for renewable projects further reinforce the role of gas-fired generation as a near-term solution.

Policymakers face competing priorities: supporting economic growth driven by digital infrastructure while advancing emissions reduction goals. In response, some jurisdictions are streamlining approvals for projects tied to grid reliability or critical infrastructure, particularly when paired with emissions controls or future decarbonization plans.

Technologies such as hydrogen-capable turbines, efficiency upgrades, and carbon capture are often cited as ways to align gas turbine expansion with climate targets. While adoption remains limited, these options are increasingly included in long-term planning.

Balancing Growth and Transition

The renewed focus on gas turbines highlights the complexity of the energy transition. Renewable capacity continues to grow, but variability and integration challenges make it difficult to meet concentrated, fast-rising loads from data centers on their own. Gas turbines provide a proven, flexible solution, but they also raise questions about emissions and long-term infrastructure commitments.

Industry stakeholders emphasize that gas and renewables can work together. Flexible gas generation supports grid stability and enables higher renewable penetration by providing backup and balancing services. For data center operators, uninterrupted power remains the top priority, with sustainability addressed through efficiency improvements, hybrid energy strategies, and emissions mitigation.

Outlook

Analysts expect gas turbine demand to remain strong through the latter half of the decade, closely tied to AI adoption and data center growth. Regions with available natural gas infrastructure and favorable permitting environments are likely to see the most activity.

As grid investments expand and next-generation technologies mature, the role of gas turbines may evolve. In 2025, however, they remain central to meeting the power demands of a rapidly expanding digital economy, bridging the gap between immediate reliability needs and longer-term energy transition goals.
