Demand Flexibility Service
Demand Flexibility Service (DFS) allows the NESO to access additional flexibility. Email alerts are available for this dataset once subscribed, triggered by any modification to the files.
The auction results will now be published below. The previous results page will no longer be updated, but will be retained to share historical data.
