Disaggregated Balancing Services Adjustment Data (BSAD)

Summary

NESO publishes Balancing Services Adjustment Data (BSAD) twice daily, covering balancing actions taken outside the formal balancing mechanism. This data feeds into the Balancing & Settlement Code for imbalance settlement processes. The dataset provides transparency on system operator interventions that sit outside standard market mechanisms.

Why it matters

This data release provides market participants with visibility of system operator actions that affect settlement but bypass competitive market processes. As such, it reveals the extent to which the system operator uses administrative interventions rather than price-based balancing, highlighting the gap between theoretical market design and operational reality.
