High-Voltage Cable Demand Threatens Clean Energy Transition
Updated June 15, 2025
the escalating global demand for high-voltage electricity cables presents a significant hurdle to the clean energy revolution. The ability to construct new wind and solar farms, along with vital cross-border power connections, increasingly relies on a supply chain struggling to keep up. Manufacturing these massive cables, essential for transporting electricity over vast distances, is a complex and capital-intensive undertaking.
Despite the soaring demand for high-voltage direct current (HVDC) cables, manufacturers are hesitant to expand production capacity. This reluctance raises concerns about whether electrification efforts can align with enterprising climate goals, geopolitical realities, and the practical considerations of large-scale industrial investments. These specialized cables, sometimes as thick as a human torso, are engineered to withstand extreme conditions and last for decades.
Claes Westerlind, CEO of NKT, a Danish cable manufacturer, noted the immense power these cables can carry. “If you look at the very high voltage direct current cable… the equivalent of one nuclear power reactor is flowing through one cable,” Westerlind said.
