LS Cable & System (LS C&S)ย andย LS Electricย have partnered withย Korea Electric Power Corporation (KEPCO)ย to build theย worldโs first superconducting power grid. Onย July 10, the three companies signed aย memorandum of understanding (MOU)ย to complete the project at aย hyperscale data centerย inย Gapyeong, South Korea, byย 2028.
Under the agreement,ย LS C&Sย will design and produceย superconducting cables, whileย LS Electricย will supplyย fault current limitersย and other advanced equipment.ย Meanwhile,ย KEPCOย will handleย technical guidance, regulatory support, and ensure project coordination. These collaborations mark a significant leap forward in nextโgeneration power technology.
LS Cable & System proved the commercial potential of superconducting cable technology in 2019. That year, it launched a 1โkm superconducting cable between SingalโHeungdeok 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 Jaโkyun called the collaboration a major milestone for the power industry. โThis project brings together three power experts to deliver the worldโs first superconducting grid for data centers,โ he said. He added that LS Cable & Systemโs cable innovation and LS Electricโs 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.
