Details

The Sizewell C capital structure will be backed by the new funding model - the nuclear Regulated Asset Base (RAB).

The RAB structure will be regulated by the UK’s independent energy regulator, Ofgem.

Revenues will be collected from electricity suppliers by the Low Carbon Contracts Company, previously designated as the counterparty for revenue collection contracts for the purposes of the nuclear RAB model.
