Market Renewal Sector Participants

MRP High-Level Designs Released

After extensive stakeholder consultation, the IESO has released high-level designs for the Market Renewal Program’s day-ahead market (DAM) and enhanced real-time unit commitment  (ERUC) initiatives.

The DAM will provide greater operational and financial certainty, while lowering the cost of producing electricity. The ERUC will help ensure the most cost-effective set of resources are used to meet demand as it changes from day-ahead to real-time. Feedback on both designs is due February 28, 2019.
