LS Cable & System (LS C&S) and LS Electric have partnered with Korea Electric Power Corporation (KEPCO) to build the world’s first superconducting power grid. On July 10, the three companies signed a memorandum of understanding (MOU) to complete the project at a hyperscale data center in Gapyeong, South Korea, by 2028.
Under the agreement, LS C&S will design and produce superconducting cables, while LS Electric will supply fault current limiters and other advanced equipment. Meanwhile, KEPCO will handle technical guidance, regulatory support, and ensure project coordination. These collaborations mark a significant leap forward in next‑generation power technology.
LS Cable & System proved the commercial potential of superconducting cable technology in 2019. That year, it launched a 1‑km superconducting cable between Singal‑Heungdeok Energy Center substations in Yongin, Gyeonggi Province. Compared to traditional copper cables, the installation reduced transmission losses by 20 times, significantly improving energy efficiency.
LS Electric Chairman Koo Ja‑kyun called the collaboration a major milestone for the power industry. “This project brings together three power experts to deliver the world’s first superconducting grid for data centers,” he said. He added that LS Cable & System’s cable innovation and LS Electric’s fault current limiter technology will drive the growth of clean, efficient, and resilient power infrastructure.
Superconducting fault current limiters play a vital role in maintaining grid stability. They instantly block fault currents, protecting equipment and preventing data loss. This technology is critical for AI and cloud data centers, where continuous and reliable power is essential for operations.
The companies will continue collaborating on superconducting grid research and development. They also plan to promote industry ecosystem growth and explore overseas markets. The Gapyeong superconducting project will serve as a global model for future deployments, particularly in regions with high energy demand from AI and cloud computing.
