Welcome to the Balancing Mechanism Reporting System (BMRS)
This BMRS website provides near real time and historic data about the Balancing Mechanism which is used by the National Grid (System Operator) as a means of balancing power flows on to and off the electricity Transmission System in Great Britain.
From 05 November 2015, the BMRS website will adopt single imbalance pricing (P305) to calculate and publish the system buy and system sell prices.
The main price calculation will also include STOR actions and the applicable Reserve Scarcity Prices (RSP).
The RSP requires Loss of Load Probability (LoLP) data to determine the value of lost load.
The BMRS website will publish this LoLP and De-rated Margin data submitted by National Grid.
In addition, BMRS may receive Demand Control Instructions from National Grid.
The BMRS website will publish these instructions and include the demand control volumes in main price calculation.
If you have any questions relating to this change, the site's main Help page has a 'What's New ...?' section that describes the change more fully and provides further information. For any other enquiries or feedback, please contact us as described on the Contact Us page.
