The IFA2 HVDC interconnector is a 1,000 MW subsea transmission link connecting the electricity grids of the United Kingdom and France. Commissioned in 2021, it is one of several strategic interconnectors operated by National Grid to enhance cross-border power flows.
The project strengthens energy security, balances renewable variability, and allows surplus renewable generation to flow between the UK and continental Europe.
