Balancing Services Adjustment Data (BSAD) Forward Contracts
Summary
NESO publishes Balancing Services Adjustment Data (BSAD) covering balancing actions taken outside the standard balancing mechanism, updated twice daily. The dataset tracks actions that affect imbalance settlement but fall outside the Balancing Mechanism's Bid-Offer Acceptances.
Why it matters

As such, it exposes the gap between what competitive markets can deliver and what system operation requires.
