Renewable Integration (SE-91)
Dispatch Technical Working Group

The Dispatch Technical Working Group (DTWG) is a working group established by the IESO through SE-91 Renewable Integration to discuss the design details associated with the Design Principles for Renewable Generation.

The group will focus on:

  • Defining the technical limitations for wind and solar generators that must be respected by the dispatch algorithm;
  • Defining the dispatch data requirements (price/quantity pairs and ramp rates) for variable generators and how dispatch instructions will be sent to these generators;
  • Defining the appropriate dispatch compliance rules for variable generators; and,
  • Defining the conditions under which variable generators are eligible to receive Congestion Management Settlement Credits.
