Perspective view of Taihan’s Second Submarine Cable PlantTaihan Selected as Government’s “Leading Company for Supply Chain Stabilization” in Submarine Cable Sector- First company in Korea’s wire and cable industry to be designated under the government-led program- Recognized for intensive investment in submarine cables and efforts to stabilize the offshore wind supply chain- Company commits to strengthening the submarine cable supply chain and supporting the sustainable development of the national energy industryTaihan Cable & Solution announced that it has been selected by the Government of the Republic of Korea as a “Leading Company for Supply Chain Stabilization” in the submarine cable sector, becoming the first company in Korea’s wire and cable industry to receive this designation. The designation is valid for an initial period of three years from the date of selection and may be extended for up to five years. The “Leading Company for Supply Chain Stabilization” program identifies companies that proactively respond to global supply chain risks while enhancing the self-reliance and competitiveness of domestic industries. Designated companies receive various forms of support, including financial assistance, policy support, and tax incentives. Taihan explained that its selection reflects comprehensive investments to strengthen submarine cable manufacturing and installation capabilities, as well as its contribution to stabilizing the supply chain for Korea’s offshore wind power industry. Submarine cables are a critical component of offshore wind power, a key pillar of the energy transition, and any disruption in their supply can delay individual projects and hinder the broader growth of the renewable energy sector. According to Korea’s 11th Basic Plan for Long-Term Electricity Supply and Demand, the domestic offshore wind market is projected to grow rapidly to approximately 14 GW by 2030. In this context, Taihan’s aggressive investments and technology development are regarded as key solutions for addressing structural shortages in submarine cable supply. In anticipation of growing demand and global supply constraints, Taihan declared the full-scale expansion of its submarine cable business in 2020 and has since strengthened its turnkey capabilities through major investments. These include the construction of a dedicated submarine cable plant, the acquisition of PALOS, Korea’s only offshore wind cable-laying vessel (CLV), and the acquisition of a specialized installation subsidiary. These efforts have enabled the company to secure and supply major domestic offshore wind projects, including Yeonggwang-Nakwol and Anma. Furthermore, Taihan is constructing a second submarine cable plant capable of producing 640 kV HVDC submarine cables and is reviewing the acquisition of a dedicated HVDC cable-laying vessel. These initiatives are progressing as part of the company’s preparation to participate in national strategic projects, including the “West Coast Energy Highway.” A Taihan official stated, “This designation reaffirms our role in establishing a stable offshore wind power value chain in Korea. Leveraging continued facility investment and technological development, we will further strengthen the submarine cable supply chain and contribute to the sustainable advancement of the national energy industry.” Companies selected as Leading Companies for Supply Chain Stabilization receive priority access to the Supply Chain Stabilization Fund, as well as various benefits such as government financial support and tax reductions.

The investment period is scheduled through December 2027. Following the investment decision, Taihan plans to break ground on submarine cable plant 2 within the year. The first phase of the new plant will be a dedicated facility capable of producing 640kV-class HVDC (High Voltage Direct Current) and 400kV-class HVAC (High Voltage Alternating Current) submarine cables. It will be equipped with cutting-edge technologies, including a VCV (Vertical Continuous Vulcanization) system — a core facility for manufacturing extra-high-voltage cables. The first phase of the plant is targeted to begin operation in 2027. A second phase of investment to further expand production capacity will be strategically pursued based on future market conditions. The site for Taihan submarine cable plant 2 is located in the Godae District of the Asan National Industrial Complex in Dangjin, Chungcheongnam-do, adjacent to the company’s existing submarine plant 1. The site spans approximately 215,000 square meters — equivalent to about 30 soccer fields. Once operational, the new plant is expected to deliver production capacity nearly five times greater than that of submarine cable plant 1. With this expansion, all of Taihan’s domestic production infrastructure — including the cable plant, solution plant, and both submarine cable plants 1 and 2 — will be concentrated in Dangjin, creating strong human and logistical synergies. Vice Chairman Song Jong-min stated, “By moving forward with the construction of submarine cable plant 2, we are not only responding to the growing demand for HVDC submarine cables, but also positioning ourselves to actively participate in the expanding ‘West Coast Energy Highway’ project.” He added, “With our turnkey competitiveness in submarine cables, we aim to lead the global market, strengthen national competitiveness, and contribute to energy security.” This investment is driven by the growing global demand for submarine cables. The submarine cable market, valued at approximately USD 4.3 billion in 2022, is projected to expand to around USD 20 billion by 2029. In particular, the global HVDC submarine cable segment is experiencing rapid growth, fueled by the development of supergrids — cross-border power transmission networks — and the large-scale expansion of offshore wind power generation. To respond to this growing demand, Taihan is steadily expanding its production capacity in phases. The company has also secured PALOS, Korea’s only CLV (Cable Laying Vessel), enabling it to manage the entire submarine cable value chain — from design and manufacturing to transportation, installation, and maintenance. As only a handful of companies worldwide possess full turnkey capabilities in the submarine cable sector, Taihan is well-positioned to secure a wide range of business opportunities in the years ahead.
