BSC Bulletin 337 - ELEXON Core Services unaffected by internal IT Security Incident

What’s happening?

Further to the BSC Bulletin 336, ELEXON confirms the core services remain unaffected by the cyber-attack.

ELEXON delivers the services of balancing and settlement via the BSC Central Systems. The BSC Central Systems include the Balancing Mechanism Reporting Service (BMRS) which publishes rational data about the balancing mechanism and settlement arrangements in real time. The Energy Contract Volume Aggregation Agent (ECVAA) which allows participants to notify their wholesale energy purchases/sales and the Settlement Administration Agent (SAA) which calculates post event settlement used for billing and post event data reporting.  

The BSC Central Systems (and their data) are hosted and operated on a secured infrastructure by a third party service provider, this is separate to ELEXON's own internal IT and have therefore been unaffected by this incident and continue to operate. There are no communications links or data traffic between the BSC Central Systems and the internal ELEXON network which was impacted by this incident.

Do I need to take any further action?

We will send further updates as soon as possible but in the meantime if you have any question please contact our externally hosted help desk on 0370 010 6950 or via email to
