Since the start of RIIO-2 in April 2021, we have been evolving to meet the changing needs of the energy industry. And we are on track to make sure that the electricity system can support 100% zero carbon power as soon as 2025.  

What is BP2?

We have now published our final second Business Plan (BP2) for the RIIO-2 period: ‘Accelerating the transition to a flexible, low carbon energy system’. BP2 sets out our goals for years three and four of RIIO-2 (2023-2025) as we respond to the rapidly changing external environment. The plan includes five new activities and 16 new sub-activities to accelerate the transition to net zero.

Our mission is to drive the transformation to a fully decarbonised electricity system by 2035 which is reliable, affordable and fair for all. We believe that the activities outlined in our plan support this mission and deliver value for customers and consumers, delivering net benefits of around £2.8 billion.

The initial plan has been updated from our April draft in response to stakeholder feedback, including an industry consultation which ran from 29 April to 10 June 2022.

What is RIIO-2?

RIIO-2 runs from April 2021 onwards and sets out price controls to determine the amount we can earn for the projects we deliver and the services we provide. It is the second price control under Ofgem's RIIO performance model. This price control makes sure that we are delivering for consumers. RIIO stands for Revenue = Incentives + Innovation + Outputs.

It is our first price control period as a legally separate ESO and covers our plans for a five-year period - 2021 to 2026. It provides an exciting opportunity for us to demonstrate how we can be more transparent, agile and innovative to enable the transition to a sustainable energy future.

The five-year period is designed with two-year planning cycles, recognising that the energy sector is experiencing an unprecedented level of change and that our plans need to remain flexible and agile in the face of substantial uncertainty.
