Accessing the data
The BMRS data is accessible through the website, Application Programming Interfaces (API)and Data Push Service.
The BMRS APIs and Data Push Service are designed to allow users to access BMRS data automatically. Depending on requirements, users can decide whether to use the API or Data Push services or a combination of the two.
The APIs use a pull mechanism, so are better suited for users needing ad-hoc access to historical information, or those who are interested in specific flows.
The Data Push Service is a new capability that allows the near real-time publishing of information from the BMRS system. This is useful for those who need the latest information from BMRS pushed to their system in near real time. Further details can be found in the BMRS API and Data Push User Guide (see “Related Content”).
The BMRS APIs and Data Push service are available to market participants free of charge to improve the service and ensure access to all users across the market.
Participants who are not BSC Parties are also required to accept the BMRS licence terms should they wish to use the BMRS data.
We publish any downtime or alteration to these services in the website Calendar and as Elexon circulars.
