Dispatch Service Working Group update

May 7, 2015

The Dispatch Service Working Group, established in 2014, discussed a transition from the current Message Exchange system to a new Dispatch Service tool more consistent with existing IESO applications. Stakeholder input has been very helpful to shape the requirements for the dispatch service which is the system used by market participants to accept and reject dispatch instructions.

The IESO will be hosting a conference call on May 21 from 9:00 -10:00 am to discuss the progress of the solution, and next steps for the project and stakeholder input.
