Ofgem is proposing that all three interconnectors put forward in its most recent “window” benefit from its “cap and floor” regime, under which consumers underwrite the project and profits are capped. It has asked for responses on the proposal by 14 August.

The three projects, which together could add 4.2GW of new connection between GB and Europe, are GridLink, NeuConnect and NorthConnect. They were all put forward during Ofgem’s second “window” for interconnector proposals.
