Capacity Auction Update

July 15, 2021

The second annual capacity auction will be held on Wednesday, December 1, 2021 for the Summer 2022 and Winter 2022-23 obligation periods. Annual capacity auctions are a key short-term mechanism to meet Ontario’s capacity needs in a flexible, competitive and transparent manner.

Organizations interested in participating in the Capacity Auction will need to complete key activities by specific deadlines. More information about these deadlines and participation in the Capacity Auction in general, can be found online.

Additionally, the IESO has posted a draft of Market Manual 12: Capacity Auctions for the 2021 auction. The draft Market Manual 12 can be found on the Pending Changes web page for stakeholder review and comment as part of Baseline 46.0.
