Fast Reserve provides the rapid and reliable delivery of active power through an increased output from generation or a reduction in consumption from demand sources, following receipt of an electronic dispatch instruction from National Grid Electricity System Operator (ESO). These reports provide information about the volume of, and time periods over which, Fast Reserve has been required. **Note** - Since the introduction of Fast Reserve dispatch instructions to our [NBM ASDP report](https://data.nationalgrideso.com/ancillary-services/non-bm-ancillary-service-dispatch-platform-asdp-instructions) on our data portal in 2020, we have continued to provide the Fast Reserve Market Information report (MIR). As the NBM ASDP report is available in CSV format and contains all of the data that we use to create the monthly Fast Reserve MIR, we believe that market providers can now use the machine readable format to undertake their own analysis of the Fast Reserve service and create bespoke reporting. In addition, as Fast Reserve is only being procured through the Optional service, there is no tender results data to share as part of market information. Therefore, we intend to stop producing the MIR for future months, and just retain all the historical MIR on our data portal, with the June 2021 report being the last one published.
