Subsea Electricity Interconnectors Database

Subsea Electricity Interconnector projects now number 765 + globally, an unprecedented growth in just a few years. Offshore Electricity Interconnection has enabled disparate grids to balance supply and demand more effectively, enabled a reduction in standby generation, enabled Islands to become part of a centralised larger grid infrastructure, and reinforced national grids by adding backbone capacity. As demand for electricity continues to rise and the drive for decarbonisation increases, this sector continues to attract government and private enterprise involvement in developing greater and greater capacity.
