Demand Response Auction

Demand response (DR) in the wholesale market is being transitioned from a contract-based program to an annual DR Auction which will provide a transparent and cost-effective way to select the most competitive providers of DR, while ensuring that all providers are held to the same performance obligations.

When does the DR Auction take place?

The DR Auction occurs annually starting on the first Wednesday of December.

What do I need to do to participate in DR Auction?

Organizations must become authorized as Demand Response Auction Participants (DRAPs) to take part in the DR Auction. Applications must be submitted at least 40 days before the start of the auction. Once authorized, DRAPs can participate in all subsequent auctions.

  • Key Milestone Dates, including submission of capacity qualification documents, payment of  auction deposit, and date of auction
  • Target Capacity

  • Maximum and  Minimum Clearing Prices

  • Capacity Limits

  • Zonal Constraints

What happens during the DR Auction?

The IESO will process all submitted demand response auction offers, determine clearing price and quantities.

The results will be published in the Post-Auction Report which includes the following for each commitment period:

  • DR Auction clearing price

  • Amount of MW cleared for each electrical zone

  • List of successful DRAPs and their DR capacity obligations

See the  most current Post-Auction Report (available on the IESO Public Reports site).

What happens post DR Auction?

Following the auction, the successful participants will be required to become authorized as Demand Response Market Participants (DRMPs), which will enable them to register resources to deliver on their DR Capacity Obligations. The participants will receive availability payments for providing DR Capacity, subject to non-performance charges.
