How Doosan Turbines Are Powering the Future of US Data Centres
| 5 min read
A South Korean energy technology company has secured a landmark contract to deliver seven 380MW gas turbines to a new data centre development in the United States — a deal that brings its total US commitments to 12 turbine units and signals a fundamental shift in how the world's most power-hungry digital infrastructure is being engineered and supplied.
The Contract: Seven Turbines, Seven Months of Deliveries
Doosan Enerbility confirmed it will supply seven units of its flagship 380MW-class gas turbine along with corresponding generators to a US client constructing a hyperscale data centre campus. Deliveries are scheduled to begin in May 2029, with one turbine-generator pair shipped each month — a structured rollout that mirrors the phased build-out of large campus-scale computing facilities.
The turbines will provide a substantial share of the facility's energy requirements as it comes online. With this agreement included, Doosan Enerbility now holds contracts for a total of 23 gas turbine units globally — 12 of which are destined for US data centre and power infrastructure projects, making the American market the company's single largest destination for turbine exports.
"Counting this contract, we will now be supplying a total of 12 gas turbines to the United States, effectively solidifying our position as a global player. Doosan plans to continuously supply competitive gas turbines going forward to effectively respond to the rising demand at both home and abroad."

Why Data Centres Are Turning to On-Site Gas Turbines
The rapid proliferation of AI workloads, cloud computing, and high-density processing has transformed data centres into some of the most energy-intensive industrial facilities on the planet. According to estimates, data centres could account for up to 12% of all US electricity consumption by 2030 — placing extraordinary pressure on an already strained national grid.
The International Energy Agency projects that most new US data centre capacity over the next decade will lean on natural gas rather than renewables alone — a frank acknowledgment that intermittent clean energy sources have not yet scaled to meet the round-the-clock power demands of hyperscale AI infrastructure. In high-demand markets like Texas and Ohio, where electricity prices are spiking, technology companies are increasingly opting for reliable on-site self-generation to sidestep transmission constraints and lock in more predictable energy costs.
The trend is already visible at the highest levels of the industry. Other AI infrastructure players have made similar moves: xAI has secured five 380MW turbines for its supercomputer expansion, while OpenAI and Meta have each pursued large-scale on-site gas generation projects across Texas and Ohio. The pattern is consistent — hyperscalers building at the frontier of AI are choosing dedicated power infrastructure over grid dependency.
The Technology: Built for Scale, Validated at Depth
Doosan Enerbility first achieved large-scale industrial gas turbine manufacturing in 2019, becoming the fifth company in the world — and the first in South Korea — to independently develop and commercialise this class of technology. Since then, the platform has been subjected to more than 17,000 hours of demonstration operations, validating its performance, efficiency, and reliability under real-world conditions across multiple facilities.
The 380MW-class turbine is designed for high-output industrial applications and is built around a skid-mounted, modular architecture that simplifies site installation and reduces on-site construction complexity. Factory-integrated digital controls enable remote monitoring and predictive maintenance — capabilities that are particularly critical in data centre environments where equipment uptime is non-negotiable.
Crucially, the turbines support up to a 15% hydrogen co-firing blend with minimal modification — keeping operational options open as hydrogen infrastructure and economics develop over the coming decade and positioning operators to reduce carbon intensity without replacing their core power assets. Carbon capture and storage (CCS) retrofits can be layered on further, giving data centre operators a credible pathway toward meaningful decarbonisation without compromising baseload reliability.
A Rare Club: Five Manufacturers Globally
Only five companies in the world manufacture gas turbines above 300MW — GE Vernova (US), Siemens (Germany), Mitsubishi Power (Japan), Ansaldo Energia (Italy), and Doosan Enerbility (South Korea). As AI-fuelled data centre projects have surged, the order books of GE and Siemens have swelled and Mitsubishi has struggled to meet delivery timelines — creating an opening that Doosan has moved decisively to fill, particularly in the US market.
US Service Capability: The Houston Advantage
A key factor underpinning Doosan Enerbility's ability to win and retain US contracts is the presence of its American subsidiary, Doosan Turbomachinery Services (DTS), headquartered in Houston, Texas. DTS handles maintenance and operational support for all turbine deployments across the US market — providing local engineering expertise, rapid response capability, and long-term service continuity that data centre operators require for mission-critical power assets.
Local service capability has become an increasingly decisive factor in infrastructure procurement. For hyperscale data centre operators, where even brief power interruptions carry significant financial and reputational consequences, the assurance of a local maintenance partner with deep product knowledge is as important as the turbine specification itself.
Looking Ahead: Gas, Hydrogen, and the Energy Architecture of AI
Beyond gas turbines, Doosan Enerbility is positioning itself across the full spectrum of next-generation energy technologies that are expected to underpin AI infrastructure over the coming decades — including Small Modular Reactors (SMRs), hydrogen turbines, and fuel cell systems developed through its subsidiary HyAxiom. The company has announced a roadmap toward a 100% hydrogen-fuelled large gas turbine by 2028 — a milestone that would represent a significant step toward genuinely low-carbon baseload power for data centres.
The broader message from this contract and the deals preceding it is clear: as the world races to build the energy infrastructure that AI demands, the competition for turbine supply is intensifying — and new entrants with proven technology, reliable delivery, and local service capability are finding a ready market. Power generation has become as strategic to the AI era as chips, cloud, and connectivity.
