Energy Efficiency Auction Pilot

Sector Evolution

The IESO is piloting an auction-based mechanism for procuring Energy Efficiency (EE) to inform long-term discussions about enabling EE to compete to meet system needs through an appropriate market-based mechanism. In particular, the IESO is seeking to understand the receptivity of the EE market to participating in auction-style procurements as well as the benefits to the system of acquiring EE through this type of competitive mechanism.

Specific pilot learning objectives include assessing the interest and ability of different sectors to participate in EE auctions, discovering the price for EE when competition for delivery is enabled, and better understanding various implementation issues.

The IESO will seek feedback from stakeholders on:

  • The high level design of the pilot auction, the associated processes and timelines as well as resource eligibility.
  • The detailed design elements of the pilot auction including the measurement and verification requirements, contract for EE delivery, as well as the process for participating in the auction. 

Additional details on the IESO’s plans to engage with stakeholders can be found in the engagement plan. All comments and enquiries on this engagement can be directed to
