Flexibility – Trades Data and Results


This dataset contains information on what we will look to put forward in our upcoming trades, with the aim to provide more visibility ahead of the actual trade opportunities.

For general Constraint Management Zone (CMZ) information and overall requirements, please go to the Flexibility – Requirements page.

National Grid facilitates its flexibility procurement activity through its online portal, Market Gateway. Flexibility Service Providers (FSPs) seeking an award to deliver flexibility services should register on the Market Gateway and complete the pre-qualification requirements to enable their eligibility to enter into flexibility Trades.

Pre-qualification is always open and can be completed at any time. Further guidance on this process is available here. Any questions should be sent to


Currently, this dataset only covers Long Term and Sustain trade opportunities in detail.

Long_Term_Trade_Parameters.csv includes information for Secure and/or Dynamic flexibility products within HV Zones, such as peak MW requirements (min, max), ceiling prices, and delivery windows (dates, times, days required).

As Sustain is the same product across both HV and LV zones, Sustain_Trade_Parameters.csv contains information for all zones where Sustain is available. This information includes the capacity we need (minimum and maximum kW), the maximum price we can pay (ceiling price £/kW/season), and service delivery windows (dates, times, days required).

For our HV Zones, graphs have been created to help visualise our Long Term and Sustain (where applicable) MW profile needs over time. These have been packaged into

The trade results are presented in the Trade_Results.csv file in detail, and in Trade_Results_Summary.csv in a more simplified, aggregated view. The weekly trade auction results are presented in the Weekly_Trade_Results.csv and Weekly_Trade_Results_Summary.csv .
