Technical Panel - Market Rule Amendment Determinations
November 13, 2026
The Technical Panel voted to recommend the following market rule amendments to the IESO's Board of Directors for review:
- Pseudo-Unit Updates: This proposal improves how pseudo-units are scheduled in day-ahead, pre-dispatch, and real-time by more accurately reflecting outages, de-rates, constraints, and ramp rates within the Dispatch Scheduling Optimizer when producing dispatch outcomes.
- Adding De-Rates to the Real-Time Lost Cost Economic Operating Point: This proposal adds de-rates to the calculation of the Real-Time Lost Cost Economic Operating Point calculations for pseudo-units.
The above amendment proposals are available on the Proposed Market Rule Amendments web page.
