RIIO is our approach to ensuring the monopoly companies who run our gas and electricity networks have enough revenue to run an efficient network that delivers what customers need. It stands for setting Revenues using Incentives to deliver Innovation and Outputs.

The current electricity distribution price control (known as RIIO-ED1) ends on 31 March 2023. The next price control (known as RIIO-ED2) will cover the five-year period from 1 April 2023 to 31 March 2028.

We began the development process for RIIO-ED2 in August 2019 with an open letter setting out the context and aims for the price control. We published our RIIO-ED2 Framework Decision in December 2019 and then our Sector Specific Methodology Decisions (SSMD) in December 2020, confirming the Methodology that we would use to apply the Framework and help set the price control.

Following our consideration of final Business Plans submitted by the Distribution Network Operators (DNOs) on 1 December 2021, we are now consulting on our Draft Determinations for the RIIO-ED2 price control.

Please send all responses by 25 August 2022 to RIIOED2@ofgem.gov.uk.

Following consideration of all stakeholder responses we expect to confirm our Final Determinations for RIIO-ED2 by December 2022.
