Conclusion (the committee's words)
The RIIO-ED1 process, which set the amount network operators could charge energy bill-payers for making upgrades to the grid over the period 2015–2023, proved overly generous. Distribution Network Operators were able to either build 108 Decarbonisation of the power sector more infrastructure that is rewarded through the Regulated Asset Value, or not spend on that infrastructure and keep a proportion of underspends. Given that technology deployment curves are hard to forecast, we understand Ofgem’s use of uncertainty mechanisms for RIIO-ED2. We will be looking to the regulator to ensure that they better manage risk and that network companies bring forward the required investment. The uncertainty mechanisms will need to be used efficiently, before customers see problems, particularly if the economics of heat pumps or electric vehicles change quickly.

Government response
The government responded to the whole report on 14 July 2023 (deadline 28 June 2023).
Summary written by Accountability Index from the government's response. It is not the government's own words.The government welcomes the Committee's report and responds to each recommendation, planning annual reporting on power sector decarbonisation while setting out where it will not adopt specific proposals.
- On the call for a long-term delivery plan, the government "plans to report on its delivery, and overall plan to deliver the commitment, on an annual basis", and is strengthening its portfolio management approach.
- On a UK-wide onshore wind target, it states that setting one "would potentially undermine the flexibility needed" across the UK.
- On biomass, it has "no plans to remove support prior to 2027" for stations already supported, saying they "have a statutory right to their existing support".
- On Ofgem's duties, it is "content to amend" Ofgem's existing duty on greenhouse gases to refer specifically to the net zero targets in the Climate Change Act 2008.
