2024/2025 Estimated Transmission Losses Adjustment values published
Following the implementation of Modification P350 on 1 April 2018, Estimated Transmission Losses Adjustment (ETLMO) values have been calculated for each season across the 2024/25 BSC Year. The Imbalance Settlement Group approved the revised Estimated Transmission Losses Adjustment (ETLMO) values for use from 1 April 2024 at its December 2023 meeting.
Please note the spring season is split into two periods, April to May 2024 and March 2025, to align with the BSC Year.

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.
