Ofgem has approved five major new undersea energy links, including three high-voltage subsea interconnector cables and Britain’s first two offshore hybrid assets (OHAs): LionLink and Nautilus.

The OHAs will directly feed energy generated by offshore wind farms in Dutch and Belgian waters into electricity grids in the UK and Europe.

LionLink, which is being developed with Dutch transmission system operator TenneT, will have an onshore landing point in Suffolk and provide up to 1.8GW of clean electricity to both the Netherlands and the UK.

Nautilus, which is being developed with Belgian transmission operator Elia, will come ashore at the Isle of Grain in Kent and will provide up to 1.4GW of offshore wind to both the UK and Belgium through subsea cables.

National Grid, which has been involved in these two projects through its investment arm, National Grid Ventures, said that these two projects combined would have the capacity to power over 4.2 million homes in the UK.
