Sonar

Welcome to SONAR

Following a full service review, launched at the Commercial Balancing Services Group, the BM Start-Up generic terms have been changed to reflect greater transparency, resulting in SONAR publishing additional information, including the BMU ids.

Together with the publication of BM Start Up instructions we are also publishing Advance Synchronisation instructions, to distinguish whether the instruction is BM Start Up or Advance Synchronisation, the details will include BPA information for BM Start Up and these fields will be blank if the instruction is an Advance Synchronisation (as cost is not incurred).
