Appeals regarding Ofgem's RIIO-2 Final Determination

03 March 2021


Some of Britain’s energy companies have appealed Ofgem’s RIIO-2 Final Determination with the Competition and Markets Authority (CMA).

An appeal to the CMA is the final step in the regulatory process which allows an independent, fair and transparent assessment of the position set out by the regulator and the network companies.

Ross Easton, Director of External Affairs at Energy Networks Association which represents Great Britain's energy network operators, said:

“The UK’s energy network operators remain focused on providing a low cost, Net Zero energy system to the public. To deliver this, it is essential that the regulatory environment is attractive to the significant investment the country needs over the coming years.”

Notes to editor

Ofgem's Final Determination for Transmission and Gas Distribution network companies and the Electricity System Operator was published on 8 December 2020.

The price control known as RIIO-2 ensures network operators have enough revenue to run an efficient network that delivers what customers need, while investing to deliver the infrastructure needed for a Net Zero future. It stands for Revenues = Incentives + Innovation + Outputs.

For the transmission and gas distribution networks and system operator, RIIO-2 will come into effect next month and runs for five years until 2026.
