Transmission Rights Market Review

The IESO has initiated a stakeholder consultation to review the current design of the IESO's Transmission Rights market. The Transmission Rights market is a financial market that provides participants with an opportunity to purchase transmission rights (TRs) through an auction administered by the IESO. The consultation will be conducted in two phases:

  • Phase one will review the confidence level and current stabilization design which is intended to balance the Transmission Rights Clearing Account and find equilibrium where the number of transmission rights sold provides for the most efficient market
  • Phase two, expected to begin later in 2013, will initiate a comprehensive review of the basic design of the TR market

This initiative will be of interest to all existing and future market participants who are transmission customers (i.e., loads), participate in the transmission rights market, or transact on the interties.

The Stakeholder Engagement Plan has been developed to define the opportunity for stakeholder involvement.
