South Korean Taihan Cable & Solution is investing USD 360 million for the first phase of construction of its second submarine cable manufacturing facility, which will, once operational, deliver a production capacity nearly five times greater than the company’s first submarine cable plant.

Taihan opened the first phase of its first submarine cable plant that produces inter-array cables, covering around 44,800 square metres behind Godae Pier at Pyeongtaek’s Dangjin Port, in May 2024. The second phase, which includes facilities for the production of export cables, was on schedule for completion by the first half of 2025.

The company’s board of directors has approved an investment of approximately USD 360 million (KRW 497.2 billion) for the first phase of construction of the submarine cable plant 2, spanning approximately 215,000 square metres, located in the Godae District of the Asan National Industrial Complex in Dangjin, adjacent to the existing plant.

Following the investment decision, the plan is to break ground this year. The first phase of the new plant will be dedicated to producing 640 kV-class HVDC and 400 kV-class HVAC submarine cables, and will feature a Vertical Continuous Vulcanization (VCV) system.

This first phase is expected to begin operation in 2027, while the second phase of investment to further expand production capacity will be pursued based on future market conditions.

According to Taihan, the investment is driven by rising global and domestic demand for submarine cables, the growth of the offshore wind power market, as well as the company’s participation in the West Coast Energy Highway project.
