MPI/API Replacement Working Group

​The IESO has formed this working group to get feedback on the MPI/API replacement refresh project. Stakeholders are asked to give input on matters relating to the redesign, transition, implementation schedule and key milestones of the project.

At the conclusion of the working group, the IESO will publish a final project plan with the implementation timeline.
