MR-00439 – Transitional Capacity Auction
Chapter 2, 3, 7, 9, 11, Appendix 2.2

The six market rule amendment proposals included in this package represent Phase I of the Transitional Capacity Auction (TCA) design, which enables non-committed dispatchable generators to participate in the TCA alongside dispatchable loads and hourly demand response resources. The TCA represents an evolution of the demand response auction into a more competitive capacity acquisition mechanism.

January 30, 2020 

 

The Ontario Energy Board (OEB) issued a final decision that lifted a stay of the operation of the (TCA) market rule amendments. The Market Rules and Manuals for the Transitional Capacity Auction, which had been stayed by the Ontario Energy Board, have been reposted.

November 27, 2019

Further to the Ontario Energy Board’s Decision and Order on a Motion to Stay the Operation of the Amendments to the Market Rules (November 25, 2019), market rule amendments for Chapters 2, 3, 7, 9, 11 and Appendix 2.2, dated October 15, 2019 concerning capacity auctions are currently inoperative pending a final determination in the Application (EB-2019-0242).
