Control Action Operating Reserve Study (SE-72)

Reliability standards allow the IESO to consider the demand relief that would result from the use of out-of-market control actions to meet the Ontario operating reserve requirement. The demand relief from these control actions, when contributing to meeting the Ontario operating reserve requirement, is termed Control Action Operating Reserve (CAOR).

The IESO is reviewing the pricing and structure of the CAOR standing offers to address the following concerns raised by stakeholders regarding the current pricing and structure:

  1. Whether the current pricing principle and structure of operating reserve is correct and/or interfering with market participant operating reserves; and

  2. The market and pricing impact of the removal of CAOR from pre-dispatch in September 2008.

This initiative will be of specific interest to all market participants who are transact in the operating reserve market. As CAOR standing offers affect operating reserve market prices and energy market prices, this initiative will be of general interest to all market participants.

This stakeholder engagement plan has been developed to define the opportunity for stakeholder involvement in the study of control action operating reserve.
