Domestic power equipment companies such as HD Hyundai Electric and Hyosung Heavy Industries are winning a series of large-scale supply contracts in overseas markets. Backed by the spread of artificial intelligence (AI) data centers and increased investment in power grids, the influence of Korean companies is expanding in key markets including the United States and Australia.

HD Hyundai Electric announced on the 2nd that it has recently signed a master long-term supply agreement worth up to KRW 1.1212 trillion for distribution equipment and power equipment with a global big tech company that is building data centers in North America. The contract value is KRW 553.9 billion for distribution equipment and KRW 567.3 billion for power equipment.

This contract adopts a package-supply method that bundles the core power infrastructure required for data centers into a combination of distribution equipment and power equipment. The company explained that package supply can improve the accuracy of power infrastructure design and reduce risks that may arise in delivery, quality, and maintenance processes.

The industry expects that the power demand of North American data centers will account for more than half of the increase in total U.S. power demand by 2030. Accordingly, demand for power equipment to ensure stable power supply is also expected to continue rising.

Hyosung Heavy Industries has signed a long-term supply contract worth KRW 310 billion for ultra-high-voltage transformers and reactors with AusNet, the transmission network operator in the state of Victoria, Australia. Ultra-high-voltage transformers are power facilities that raise or lower voltage for long-distance transmission, while reactors are facilities that suppress voltage fluctuations in transmission networks to maintain stable power systems. Under this contract, Hyosung Heavy Industries will exclusively supply ultra-high-voltage power equipment to the Victoria transmission network for the next five years. This is a large-scale contract following the KRW 142.5 billion energy storage system (ESS) project it won in March in the state of Queensland, Australia.

Hyosung Heavy Industries currently holds the No. 1 market share in Australia’s ultra-high-voltage transformer market. Cho Hyun-joon, Chairman of Hyosung Heavy Industries, said, “We will not only supply power facilities, but also become a company that provides solutions to Australia’s energy policy challenges.”

Meanwhile, LS ELECTRIC held the “LS ELECTRIC DC Factory Completion Ceremony” on the 2nd at its Cheonan plant in South Chungcheong Province and is beginning full-scale operation of the world’s first 100% direct current (DC) distribution plant. The newly completed LS ELECTRIC DC Factory is the world’s first DC distribution manufacturing facility, into which a wide range of LS ELECTRIC’s DC-dedicated core equipment—such as solid-state transformers (SST), solid-state circuit breakers (SSCB), and energy storage systems (ESS)—has been applied. DC distribution technology is emerging as a key issue in the power industry as demand for artificial intelligence (AI) data centers surges. While current power grids are centered on alternating current (AC), many facilities such as data centers and solar power systems are DC-based, so the introduction of DC distribution technology can prevent power losses that occur in the process of converting from AC to DC.
