Stage status timestamp (balancing complete): 2026-05-29T10:50:00Z
Illustrative imbalance pricing (Trading Rules R2 §07 placeholder formula). Balancing consumes the final post-IDM schedule and prices each party's deviation from it against the metered outturn.
Per-party imbalance settlement
Metered outturn vs final schedule. A modelled residual under-delivery of 20.6 MWh sits on Eskom Holdings — coal fleet (Generator) so the balancing market has a real action to price.
| Party | Final sched (MWh) | Metered (MWh) | Imbalance (MWh) | Imb. price (R/MWh) | Amount |
|---|---|---|---|---|---|
| Eskom Holdings — coal fleet (Generator) | 26066.0 | 26045.3 | -20.6 | R2000.00 | R-41266.67 |
Implied under-delivery penalty: SMP × 1.15 or an R2 000/MWh floor, whichever is higher. The floor binds when the SMP is below R1 739,13/MWh. Illustrative, basis pending NERSA (Trading Rules R2 §07 placeholder).
