Ofgem is proposing approving three new electricity interconnectors that would link the UK with other nations.
Two of the power links – FAB Link and IFA2 – would connect Britain’s electricity system with France and one – Viking Link – with Denmark, providing 3.4GW of extra capacity.
The regulator is consulting on its proposals until 2nd May 2015.
The three projects are expected to benefit UK consumers by around £8 billion over 25 years.
Ofgem is however not taking forward the ‘Greenlink’ interconnector linking England with Ireland as it “does not provide sufficient value for consumers”.
Martin Crouch, Ofgem’s Senior Partner for electricity transmission said: “These three interconnectors would further boost Britain’s energy security and reduce pressure on bills. To date, under our cap and floor regime, we are looking at adding around 5GW to Britain’s energy supply.”
