Power Cables Market Growth Analysis, Competitive Landscape & Forecast, 2026-2033

Expansion of Submarine Interconnectors and Offshore Wind

Offshore wind is also presenting an increasingly specific opportunity for submarine power cables to link generating facilities with onshore transmission networks. Interconnectors between countries are another avenue for growth, enabling the trade of power across national boundaries and helping balance renewables. Prysmian established the technology path back in March 2026 when it completed testing of a 525kV submarine HVDC cable capable of transmitting 2.5 GW per cable at elevated temperatures. Both of these innovations enable higher capacity transmission while requiring fewer cables. Suppliers with submarine manufacturing, installation vessel, testing, and project management capabilities will benefit more, as the technology is more challenging than traditional cables.
