IESO Board of Directors approves market rule amendments
August 30, 2018
The IESO Board of Directors approved the following market rule amendments on August 29, 2018:
MR-00420: Capacity Exports:
R00 - Capacity Exports in the IESO-Administered Markets
R01 - Capacity Exports and Settlements
R02 - Capacity Exports and Transmitter Outages
The amendments create a framework to enable Ontario-based resources to export capacity, as approved by the IESO. The amendments will specify market participant rights and obligations for capacity export requests and the capacity call process, specify congestion management settlement credit and cost guarantee treatment, as well as enable the IESO to reject or revoke a transmitter’s planned outage in limited circumstances.
The amendments are based on input from the Market Renewal - Capacity Exports stakeholder engagement.
The effective date of the amendments is expected to occur in November 2018, upon the implementation of required market manual changes. The IESO will specify the effective date in a notice to all market participants.
MR-00433: Demand Response:
R00 - Notification and Activation of Hourly Demand Response
R01 - Hourly Demand Response to the EOSCA List
The amendments will increase the utilization of Hourly Demand Response (HDR) resources by modifying the requirements for standby and activation notices, reducing the minimum dispatch duration, and explicitly identifying activation of HDR resources as a control action on the Emergency Operating State Control Actions (EOSCA) list.
These amendments are based on input from the Demand Response Working Group.
The effective date for R00 is expected to be in May 2019, upon the implementation of the required IT system changes and to align with the start of the delivery period associated with the next DR auction. The IESO will specify the effective date in a notice to all market participants. The effective date for R01 is September 21, 2018.
