The Balancing Mechanism Reporting Agent (BMRA) uses ETLMO values to calculate indicative charges and payments for Balancing Mechanism (BM) actions, and the Energy Imbalance Price, in near to real-time.
ETLMO values are used to report indicative data on the Balancing Mechanism Reporting Services (BMRS), and will be published within the Operational Data section of the Elexon Portal.
