Changes to Day-Ahead Production Cost Guarantee - Chapter 7, Market Rules (SE-102)

After initial discussions with stakeholders, the IESO has launched a consultation to develop a market rule amendment to address situations where ramping down over hour ending one is causing inappropriate Day Ahead Production Cost Guarantee (DA-PCG) payments.

The IESO has identified these inappropriate payments as being caused by a combination of low real-time offers for hour ending 24, high day-ahead offers for hour ending 1, and a ramp rate that prohibits the unit from ramping down in one hour or less for hour ending 1. High incremental energy and speed-no-load offers for hour ending 1 can lead to substantial DA-PCG payments for that hour.

Gas generators that are eligible for Production Cost Guarantees and associated service providers will be most interested in this consultation.
