An Ontario utility prepares for a five-day cold event where demand is forecast to exceed normal winter levels.
- expected peak-day demand: 100 units
- firm transport receipts: 65 units
- planned storage withdrawal capacity: 30 units
- linepack flexibility: 5 units
Total available under plan = 100 units.
Forecast uncertainty of +/- 5 units means the utility may still need same-day balancing actions.
Possible actions include:
- nomination adjustments
- additional spot purchases
- interruptible curtailment protocols if conditions worsen
- deliverability, not just annual supply, drives peak reliability
- storage withdrawal constraints are critical risk points
- accurate weather and demand forecasting materially affects outcomes
