National Grid ESO are again launching the Demand Flexibility Service (DFS) for Winter 2023/24. The service allows the ESO to access additional flexibility when the national demand is at its highest – during peak winter days – which is not currently accessible to the ESO in real time. The service will allow consumers – both domestic and I&C – to be incentivised for voluntarily flexing the time during which they use their electricity.
This dataset contains updates and information relating to both Live and Test Events.
Text message/SMS alerts will be available for this dataset before the service goes live in late October 2023.
This dataset will contain the following files:
DFS Utilisation Report: This file will provide details of accepted and rejected bids for both Live and Test Events and includes a breakdown by GSP. The ESO will endeavour to update this file within one hour of bid submission gate closure – which occurs one hour after the DFS Service Requirements are issued. Note: this file will only be updated on days with a corresponding DFS Service Requirement.
DFS Utilisation Report Summary: This file will provide a summary of the demand flexibility volumes procured and delivered for both Live and Test Events. The file will be updated after the DFS Utilisation Report has been updated and/or when the relevant settlements data has been processed.
DFS Industry Notifications: This file will indicate when the ESO anticipates publishing a DFS Service Requirement for a Live or Test Event, and will provide additional information pertaining to the issuance of a DFS Service Requirement.
- DFS Service Requirement: This file will contain details of Service Requirements for both Live and Test Events.
