The LionLink project was launched in April 2023, when the Netherlands and the UK unveiled their plan to build LionLink and said this would be a first-of-its-kind electricity link to connect offshore wind between the two countries via interconnections.

Shortly after this, National Grid Lion Link Limited applied for the electricity interconnector with the UK energy market regulator Ofgem, requesting a licence that would authorize it to participate in the operation of the interconnector in Great Britain.
