Mid-term market (Y-1)
We are currently working through some outstanding design questions and as we develop the design, we are engaging with industry on the proposed.
Below you can find the latest material from our workshops and webinars.
Reactive Power Market - November 2024
We hosted an initial webinar on 13 November. The purpose of this was to provide a recap of the Future of Reactive Power Market innovation project, with a specific focus on the mid-term market. This included NESO’s current thinking, next steps and how industry can get involved.
The Market Engagement RFI was a voluntary RFI seeking voluntary views, NESO is not exercising its RFI powers under the Energy Act 2023, but NESO still reserves the right to issue RFIs under this Act. This closed on Friday 13 December 2024.
Update: December 2022 - Request for Information Accessing Additional Voltage Capability 2023 - 2026
Earlier this year, National Grid ESO launched a request for information (RFI) to look at accessing additional reactive capability across England and Wales between 2023 and 2026.
We received considerable interest with over 100 solutions and over 8 GVAr volume submitted by providers:
- 58 transmission-connected responses totalling 5.4 GVAr
- 56 distribution-connected responses totalling 2.9 GVAr
Note the above volumes have not been subject to effectiveness studies.
The responses to the RFI have demonstrated that there is considerable additional capability potentially accessible to ESO which is really encouraging. We have also learnt that many parties who have mandated reactive power obligations also have the capability and desire to deliver additional reactive power. The RFI also presented a growing appetite to deliver reactive power capability from units connected at the distribution level which traditionally do not offer such services to ESO, appreciating the challenges around effectiveness.
For distribution-connected submissions, ESO require studies from our Distribution Network Operator stakeholders in order to determine the effectiveness and viability of submissions. We continue to progress these discussions and hope to be able share next steps early in the New Year.
We have been able to make faster progress on the transmission-connected solutions as these types of assets by nature have much greater effectiveness on the network. We are pleased to be able to offer these solutions a new commercial services agreement to cover capability outside of grid code obligations and we will be reaching out to parties shortly to outline how we intend to implement these agreements within our current processes.
ESO will share further updates and plans on this webpage. We thank parties for their submissions into the RFI and look forward to continuing to progress accessing additional capability within the market.
