Energy Detailed Design Engagement

The Energy work stream of the Market Renewal Program (MRP) will improve the way electricity is priced and scheduled in order to meet Ontario’s energy needs reliably, transparently and efficiently.

Since posting the final high-level design documents for the Energy work stream in August 2019, the IESO has shifted its focus both internally and with its active stakeholder community on developing the specific changes and details required to implement these initiatives in the IESO-administered market.

The Replacement of the Settlement System (RSS) is a key project that will see a complete modernization of the IESO’s settlement system, the tool used to produce statements reflecting market participants’ involvement in IESO-administered markets. This project will address limitations within the existing system and processes, and integrate changes resulting from the Market Renewal Program (MRP) and future IESO initiatives.
