How does the Nuclear Regulated Asset Base impact your bill?
What is the Nuclear Regulated Asset Base (RAB)?
The Nuclear Regulated Asset Base (RAB) scheme will be introduced to help fund future nuclear projects – and this will become a charge on your electricity bill.
What is this about?
Introduced as part of the Nuclear Energy (Financing) Act 2022, the Nuclear RAB is designed to support design, construction, commissioning and operation costs of new nuclear projects – starting with the Sizewell C nuclear site in Suffolk.
All suppliers will be required to fund the Nuclear RAB arrangements through the Supplier Obligation mechanism – which also funds the Contracts for Difference (CfD) scheme – based on their market share. The cost of this mechanism is reflected in the non-commodity element of consumer bills.
What does this mean for me?
Although the Nuclear RAB follows a similar structure to CfD, there is a key difference between the two schemes: CfD participants are already generating electricity, while RAB costs are going to be reflected in consumer bills from the construction phase.
When is this happening?
There is no current start date for the Nuclear RAB due to ongoing investor conversations, which could mean the scheme does not begin until mid-2026.
However, due to the nature of the mechanism to fund the scheme, the Nuclear RAB will begin to appear as an additional cost on your electricity bill soon after launch.
