This paper builds on the approach outlined in the National Infrastructure Assessment by providing a method for evaluating the type and scale of costs associated with applying a regulated asset base (RAB) model.

This includes costs related to the transfer of risk between the private sector, electricity consumers and the taxpayer which are at risk of being ignored as they are not accounted for in the headline price paid by consumers under a RAB model. The evaluation method takes in to account the characteristics of building and operating a nuclear power plant, which are different to projects where the RAB model has been applied in the past.

Informing this paper are separate technical annexes on nuclear power reference classes produced for the Commission by Oxford Global Projects.
