Great Britain has electricity interconnectors with France (4 GW), Norway (1.4 GW), Belgium (1 GW), the Netherlands (1 GW) and the island of Ireland (1 GW). There are currently no electricity interconnectors to Iceland.

The Government works closely with National Grid Electricity System Operator (ESO) and the transmission system operators of all connected countries to ensure that the maximum interconnector capacity is available for use.

Increased interconnection promotes competition, leading to reduced consumer bills. Ofgem estimated the net total quantifiable impact on GB consumer welfare to be greater than £20 billion for projects under their regulatory regime, to date.
