TenneT to undertake demonstration project for innovative ‘super cable’

• Superconducting power cable represents world first for European high-voltage grid
• Cable may be suitable for integration of high-voltage infrastructure in urban areas
• Demonstration project comprises two to four kilometres of underground 150 kV HTSC cable

TenneT is planning to install two to four kilometres of underground superconducting high-voltage cable as part of the Dutch electricity grid. The project will be a world first: a section of superconducting cable of this length has not yet been installed anywhere else in the world. “With this project, we are meeting society’s demand to install more high-voltage lines underground,” says TenneT CEO Mel Kroon. “With these superconducting cables, it should become easier in future to integrate high-voltage lines in urban areas.” …
