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.

For more information on this stakeholder initiative please review the Background Memorandum.
