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. RIIO stands for Revenues = Incentives + Innovation + Outputs.
In December 2018, we consulted on proposals to set the sector-specific methodologies for the Electricity Transmission, Gas Transmission, Gas Distribution and the Electricity System Operator RIIO-2 price controls starting on 1 April 2021. This document sets out our decision on the policy areas applying across these sectors, except where otherwise indicated. There is a separate annex setting out Finance decisions. Further information on decisions for each sector are set out in separate annexes to this document. Network companies will use this information to develop their Business Plans over the remainder of 2019.
