Europe's High-Voltage Subsea Cable Shortfall Predicted by TGS | 4C Analysis
Europe may face a deficit exceeding 22,000 KM of high-voltage subsea cables from 2026 to 2040, impacting offshore wind projects. TGS | 4C warns of a potential 27% annual supply shortfall due to accelerating demand outpacing manufacturing capacity.

TGS | 4C analysis indicates Europe could lack over 22,000 KM of high-voltage subsea cable capacity by 2040, raising concerns for offshore wind and electricity transmission projects. The Hamburg Declaration, signed by nine countries in January 2026, aims to establish 100 GW of cross-border offshore wind capacity by 2050.
Current manufacturing constraints, with lead times of 4-6 years for new investments, could delay project timelines. Interconnector projects typically take an average of 13.3 years from planning to commissioning.
European manufacturers lead the subsea cable market, holding 91% of contracts, while the market is projected to grow at a CAGR of over 6.5%. The UK is expected to drive growth due to increased offshore wind installations.
