South Korean conglomerate Hyundai Heavy Industries has signed its first natural gas turbine supply deal in the US with Aperion Energy Group, a Texas-based energy solutions developer for the data center market.

The contract, valued at around $423.7 million, covers 684MW of power capacity and represents the largest power engine order in the company’s history. According to the companies, the equipment will be used to support data center power infrastructure in the US.

As part of the agreement, Hyundai will supply a number of its 20MW-class HiMSEN engines, which are designed for power generation. The company said the engines offer high output, fast startup times, and stable load response, making them suitable for data center environments where continuous operation is required.

“This contract will serve as an important foothold for entering the US data center market,” said Han Ju-seok, head of HD Hyundai Heavy Industries’ engine and machinery division. “We will continue strengthening our position in North America and create more opportunities in the power generation business, including the data center sector.”

The agreement marks the company’s entry into the US data center market, with plans to expand further into related areas such as backup power and industrial energy systems.

While this is its first US data center deal, the wider Hyundai group has a long history with the sector, having announced several large-scale investment packages over the past few years to support AI development in South Korea. In November, the company, alongside Samsung, announced around $400bn in domestic investments in AI.

In February, the company said it planned to invest ₩10 trillion ($7.5bn) in South Korea’s Saemangeum development zone, where it intends to build an integrated AI data center campus.
