Market Renewal - Capacity Exports


Through this engagement, the IESO investigated the potential to allow Ontario generators to export their capacity to other jurisdictions.

Market Renewal Engagement

Beginning in 2016, the IESO held a series of consultations with stakeholders on the rationale, scope and set of initiatives which should be included under the program and developed the Market Renewal Engagement framework. During this time, the IESO also worked with stakeholders and its consultant on the development of a benefits case for market renewal (completed in April, 2017).

Since that time, stakeholder consultations on Market Renewal have evolved and take place within engagements focused on specific initiatives.
