HD Hyundai Heavy Industries has landed its largest power-generation engine contract ever: a deal worth more than $400 million to supply natural gas turbines capable of producing 684 megawatts of electricity for data centers in the United States. The order, disclosed through Korean financial filings on April 22, 2026, underscores how aggressively data center operators are pursuing off-grid power solutions as artificial intelligence workloads push electricity demand to levels the existing grid cannot reliably meet.
The contract is valued at 627.1 billion won, according to Chosun Biz, which reported it as the company’s biggest power-generation engine order on record. For perspective, 684 megawatts is roughly enough to power several hundred thousand homes, though data centers consume electricity at far greater density per square foot than any residential building.
Who is buying and what they are getting
The buyer is Aperion, a firm focused on supplying power to the U.S. data center market, according to Data Center Dynamics. Neither HD Hyundai Heavy Industries nor Aperion has issued a public press release confirming the arrangement, and Aperion’s existing operations, ownership structure, and client relationships remain thin in the public record. Whether the company is developing its own generation facilities or acting as a power intermediary for larger operators has not been clarified.
The equipment consists of natural gas turbines designed for on-site or near-site generation, meaning the data centers they serve would produce their own electricity rather than drawing additional load from the public grid. That approach has gained traction across the industry because new grid interconnections and transmission upgrades can take years to permit and build, while gas turbines can be deployed on a faster timeline.
Why the numbers vary
Reports on the contract’s dollar value range from roughly $423 million to $463 million. The gap is largely a function of currency conversion timing: the won-denominated figure of 627.1 billion won translates differently depending on the exchange rate applied, and no English-language financial filing has been released to pin down a single dollar amount. The most defensible characterization is that the deal exceeds $400 million, with the precise figure falling somewhere in that range.
Separately, Aju Press referenced a $4.6 billion figure tied to HD Hyundai Heavy Industries’ U.S. data center power equipment pipeline. That number almost certainly reflects a cumulative or forward-looking supply target rather than this single contract, though the distinction was not clearly drawn in the original Korean-language reporting.
A crowded race for data center power
The deal arrives at a moment when virtually every major turbine manufacturer is chasing the same opportunity. GE Vernova, Siemens Energy, and Mitsubishi Power have all reported surging demand from data center developers seeking dedicated generation capacity. HD Hyundai Heavy Industries’ entry into this market at the 684-megawatt scale signals that Korean heavy-industry firms are now competing directly for contracts that were once dominated by Western and Japanese suppliers.
Natural gas turbines offer speed and reliability, but they carry tradeoffs. Operators lock themselves into long-term exposure to natural gas price swings, and the carbon emissions from gas-fired generation have drawn increasing scrutiny from regulators and environmental groups, particularly in data center-dense states like Virginia and Georgia. Neither HD Hyundai Heavy Industries nor Aperion has publicly addressed how this project fits within any decarbonization framework.
Grid strain and the policy backdrop
The contract also reflects a broader infrastructure crisis that U.S. policymakers are still struggling to address. The Department of Energy has repeatedly flagged grid reliability as a top concern, warning that surging data center loads risk destabilizing regional power networks if new generation and transmission capacity do not keep pace. FERC interconnection queues, where new power projects wait for approval to connect to the grid, have ballooned to more than 2,500 gigawatts of proposed capacity nationwide, with average wait times stretching beyond four years. State-level permitting battles in Virginia, Georgia, and Texas have further slowed the buildout of both generation and transmission infrastructure, pushing developers toward self-supplied solutions like the gas turbines in this deal.
“The U.S. grid was not designed for the load growth we are seeing from data centers,” said Jason Shaw, chairman of the Georgia Public Service Commission, in public remarks earlier in 2026. “We need every tool available, and we need regulatory frameworks that can move at the speed the market demands.”
An HD Hyundai Heavy Industries spokesperson told Chosun Biz that the company views the U.S. data center power market as a “core growth engine” and plans to pursue additional contracts in the sector through the remainder of 2026.
What is still missing
Several key details remain undisclosed. No reporting has identified which U.S. states or regions will host the turbines, and no delivery or commissioning timeline has been confirmed. For data center developers racing to bring new capacity online before 2028, the installation schedule matters as much as the megawatt total. Without it, the operational impact of the deal cannot be fully assessed.
The specific data center operators who will ultimately consume the electricity have not been named. In similar deals, the end users have included hyperscale cloud providers like Amazon, Microsoft, and Google, but no such connection has been established here.
How gas turbine orders fit the wider power scramble for AI
The broader pattern is unmistakable. As AI training runs and inference workloads drive unprecedented electricity demand, U.S. data center operators are bypassing grid bottlenecks by building their own generation. Nuclear restarts, long-term solar and wind contracts, and now large-scale gas turbine orders are all part of the same scramble. This contract ranks among the largest single orders in that trend, and its execution will test whether modular gas turbine deployments can scale fast enough to keep pace with a construction boom that shows no sign of slowing.
