Webinar – Interchange Enhancements – November 29, 2016
The IESO is planning to make changes with respect to the submission of e-Tags and the management of those transactions specifically within the mandatory window. All interested stakeholders are invited to a webinar on Tuesday, November 29 from 1:00pm-2:30pm to discuss these changes.
The Interchange Enhancements project is aimed to improve the operation and management of interchange scheduling related tasks by enhancing existing interchange scheduling systems and processes. To support this objective, the project aims to limit manual intervention and error margins and reduce time spent on the phone for both market participants and the IESO’s control room operators. One of the main benefits the IESO is pursuing will be to enable market participants to manage e-Tag ID changes electronically, without the need for IESO operations approval within the existing mandatory window.
For more information on the project and its potential impact on the manner in which your organization manages e-Tags, please register with
IESO Engagement to receive the webinar log-in details. Stakeholders will have an opportunity to ask questions, seek clarification and provide comments on the material presented.
Webinar – Grid-LDC Interoperability Framework – November 25, 2016
The IESO is hosting an information webinar on Friday, November 25 at 1:00 pm to discuss the development of a grid-LDC interoperability framework. The objective of the framework will be to identify opportunities to enhance the reliability and efficiency of Ontario’s electricity grid through the coordination of IESO and LDC-controlled resources. It is anticipated that operations representatives of LDCs will have the greatest interest in this webinar; however, all interested parties are welcome to participate. To register, email
Grid-LDC Coordination partnership with PowerStream, the IESO has identified existing real-time IESO market and system information that may be useful to LDCs in managing their day-to-day operations as well as a number of short and long-term collaboration opportunities for the IESO and LDC’s. The IESO will present these early learnings during the webinar and provide an opportunity for input on the draft framework including identifying any barriers or other opportunities that might not have been contemplated thus far.
