Taihan Cable & Solution (Taihan) announced that its U.S. subsidiary, Taihan USA, has secured a 230 kV extra-high-voltage (EHV) power grid project in the United States valued at approximately 100 billion won, or about $70 million.
Turnkey 230 kV project in Southern California
According to a report from Yonhap News Agency, the contract covers a 230 kV high-voltage AC cable system for a utility in Southern California and will be executed on a full turnkey basis. While Taihan had not yet published a formal press release at the time of reporting, multiple South Korean media outletsโincluding Asia Economy and Walk into Koreaโconfirmed the project scope in the Riverside region.
Asia Economyโs English-language service reported that Taihan will handle system design, cable production, delivery, on-site installation, and commissioning. Yonhap added that Taihan will oversee the full project lifecycle, including planning, manufacturing, installation, and testing.
Long-term focus on the U.S. grid market
Taihan has steadily expanded its presence in the U.S. electric grid market since 2017. That strategy has delivered record annual orders, including approximately $280 million to $300 million in 2022 and an additional $90 million to $100 million in U.S. grid contracts awarded in mid-2024.
An analysis published by The Korea Times projects that U.S. electricity demand will rise from roughly 4,100 terawatt-hours in 2024 to more than 5,000 terawatt-hours by 2030, reinforcing long-term investment in transmission infrastructure.
Technical expertise drives project wins
Taihan stated in multiple reports that it has secured every 500 kV AC project it has pursued in the U.S. The company credits its success to deep experience in technically complex projects, including 320 kV HVDC transmission systems and replacement programs for aging urban power grids.
That portfolio includes numerous 230 kV and 500 kV underground transmission projects supporting large-scale solar and wind developments in California, as well as grid renewal programs in major U.S. cities.
Global backlog supported by HV and offshore projects
According to a Korea Herald report, Taihanโs recent U.S. wins complement a global portfolio of ultra-high-voltage projects in markets such as Singapore, Qatar, and the United Kingdom. These awards have pushed the companyโs total order backlog to approximately $2.5 billion.
โStarting with this early win, we aim to build further momentum,โ a Taihan Cable official told Yonhap. โAs U.S. grid modernization and large-scale investment accelerate, we will leverage our local presence to expand projects nationwide and strengthen our market position.โ
Beyond land-based and underground transmission work, Taihan has also been selected as a preferred or confirmed supplier for inter-array and onshore grid packages tied to offshore wind projects. According to Korea Herald and Offshore Energy, the company is currently building a second submarine cable plant in South Korea to support that expanding business.
