Our Net Zero Market Reform programme was established in early 2021 to examine holistically the changes to current GB electricity market design that will be required to achieve net zero.
We will continue to share our views on the future direction of market reform, while also working closely with DESNZ as a trusted strategic partner in the Review of Electricity Market Arrangements (REMA).
Please find our recent updates on the programme in the ‘key updates’ section of the webpage below.
The Net Zero Market Reform programme has been split into four phases as follows:
Phase 1– Scoping (completed March 2021)
Analysis of the GB market landscape and review of international case studies. The purpose of this phase was to set out the framework for future phases of work.
Phase 2 – “Case for change” analysis and identification of options (completed November 2021)
Deep dive analysis into current and future market issues, defining market objectives and success criteria with a view to Carbon Budget 6 and net zero, and identification of a long list of market reform options to tackle the issues identified.
Phase 3 – Assess operational elements and share conclusions (completed May 2022)
Evaluation of a range of credible market design options against assessment criteria and sharing of initial findings on the future direction of market reform.
Phase 4 – Assess investment elements and share conclusions with holistic vision for REMA
Continuation of our evaluation of a range of credible market design options against assessment criteria and sharing of findings on the future direction of market reform.
To achieve market reform, we need to work together across the energy industry. We host regular events and workshops to give opportunity for stakeholders to provide their input. If you have any questions or to find out how to get involved please email [email protected]
Below you can find core updates from the programme so far.
On 4 July 2023, we hosted our Net Zero Market Reform Phase 4 conclusions webinar. During the event we presented an overview of the NZMR programme to date, our assessment of investment policy options for net zero, and our conclusions.
We also hosted a panel discussion titled "How should investment policy evolve to support a net zero market," and were joined by James Samworth from Schroders Greencoat, Rachel Fletcher from Octopus Energy, and Andrew McAleavey from Penso Power Ltd. This event will be followed up with a more detailed report in the autumn.
See below the recording from the event, the presentation slides, Q&A, and a more detailed version of the slide pack.
27 February 2023
On 27 February 2023 we published Baringa’s independent assessment of investment policy options and market design packages. As set out in our foreword to their assessment, we commissioned Baringa’s analysis as part of the fourth phase of our NZMR programme and to support the debate around market reform driven by the Government’s Review of Electricity Market Arrangements. We will now be forming our conclusions on holistic market design, which will pull together various analyses including Baringa’s assessment, to be published in Summer 2023.
See below, Baringa’s full assessment with ESO’s foreword.
24-29 November 2022
On 24 and 29 November 2022 we hosted online workshops where our partners at Baringa presented results from their independent assessment of market reform packages. Many thanks to all who participated and shared their views on Baringa’s approach and assessment results, which will inform ESO’s own assessment. This event will be followed up with publication of Baringa’s independent assessment followed later by ESO’s full report in 2023.
See below a summary of the workshops, the recording of Baringa’s presentation, the presentation slide pack, and the pre-read slide pack.
10 October 2022
On 10 October 2022 we submitted our response to BEIS’ Review of Electricity Market Arrangements (REMA) consultation, informed by our Net Zero Market Reform programme analysis. REMA represents the most far-reaching review of energy market arrangements since privatisation. We hugely welcome REMA’s long-term focus and believe its outcomes will be transformative in delivering decarbonisation, system security and value for consumers. We look forward to working with BEIS, Ofgem and the wider industry to help design and deliver the market reform outcomes that REMA has set out to achieve for GB consumers.
28 September 2022
On 28 September 2022 we presented an update on Phase 4 of our Net Zero Market Reform programme at Markets Forum. During the event we presented the evolving context of the energy landscape, a recap on the programme to date, an updated case for change with a focus on investment elements, and our latest thinking on the shaping of Market Reform packages. We also hosted two breakout discussions with industry experts, led by Baringa, where we discussed with stakeholders our approach to package design and an initial overview of our packages.
See below the recording from the event, the presentation slide pack, and Baringa’s approach to packages that we discussed in the breakout sessions.
24 May 2022
Following our presentation at the Markets Forum in March, on 24 May 2022 we published an update on our Net Zero Market Reform programme which presents our assessment and conclusions from Phase 3.
In this publication we have focused on assessing the operational elements of market design: location and dispatch. These are initial findings, based on substantial analysis and stakeholder engagement.
See below the interactive document, print-ready document and separate supporting evidence annex.
22 March 2022
On 22 March 2022 we hosted our Net Zero Market Reform Phase 3 conclusions event. During the event we presented a re-cap of the programme to date, the case for market reform, the outcome of our assessment of the Operation market design options, and our conclusions. We also hosted a panel discussion with industry experts where we discussed our conclusions and answered questions from the audience. This event will be followed up with a detailed report to be published in May.
See below the recording from the event along with a more detailed version of the slides that were presented.
17-18 January 2022
On 17 and 18 January 2022 we hosted our first Net Zero Market Reform events of Phase 3. The objective of these sessions was to share the refined market design options for each of the key market design elements identified in Phase 2. On 17 January we focused on the market design elements that fall under the Operation category and on 18 January we focused on the market design elements that fall under the Investment category.
See below recordings of each event and the slides presented by our project partner FTI consulting during the sessions.
18 November 2021
On 18 November 2021 we published an update on our Net Zero Market Reform programme which presents our conclusions from Phase 2. It draws together the results of modelling analysis with insights from ESO experts and external stakeholders. In this publication we identify the key challenges for markets to address on the road to net zero, set out our framework for assessing the different market design alternatives, and present the list of options we are taking forward for detailed consideration in our next phase of work.
See below the interactive document, the print ready document and the recording from the Market Forum event on the same day where we provided an overview of the publication.

On 14 September 2021 we hosted a workshop to develop a long list of possible market design options consistent with achieving net zero and to discuss what assessment criteria should be used to assess the relative merits of the different options.
In July 2021 we hosted three workshops looking at the case for market reform (“case for change”). The workshops focused on investment, flexibility, location, and whether current market design drives the right signals to achieve a net zero energy system.
On 22 June 2021 we presented an update on our NZMR programme and our approach to tackling the case for market reform (“case for change”); we also hosted a panel discussion with BEIS and Ofgem on market reform and the associated challenges.
On 25 March 2021 we launched Phase 2 of the Net Zero Market Reform programme, shared key insights from Phase 1 and outlined our high-level plans to progress our review of GB electricity market design.
