Aggregated Balancing Services Adjustment Data (BSAD)
Summary
NESO publishes aggregated data on balancing actions taken outside the standard balancing mechanism, updated twice daily. The Balancing Services Adjustment Data covers actions submitted to the BSC for settlement purposes. This is routine operational data publication from 2019.
Why it matters
This provides transparency on out-of-market interventions but does not change the underlying settlement or balancing mechanisms. As such, it offers visibility into system management costs without altering the incentive structures that drive balancing service deployment.
