Assessment of the Day-Ahead Commitment Process (SE-22)

The day-ahead commitment process (DACP) is an initiative designed to increase reliability in the short term that was approved by the IESO Board of Directors on December 7th, 2005.

The design, along with previous stakeholder engagement information, can be found at: Day-Ahead Commitment Process Design (SE-7). Following approval of the DACP by the Board, a stakeholder plan was created for the implementation phase, which is available at: Implementation of Day-Ahead Commitment Process (SE-16).

Assessment of the Day-Ahead Commitment Process
To evaluate the effectiveness of the DACP, the IESO will implement performance measures, monitor and report results. The assessment will address the extent to which the DACP improved reliability, impacted the behaviour of market participants and impacted price. Under the DACP design, there is a requirement for the IESO to review and assess the effectiveness of the DACP when the IESO constrains-on Ontario generators. Where the IESO uses this authority, it will be tracked and reviewed to provide the circumstances and rationale for these actions.
