The program initiatives – the single schedule market (SSM), day-ahead market (DAM) and enhanced real-time unit commitment (ERUC) – will make improvements to the current market design, leading to system efficiencies and support the grid of the future. This project will deliver significant value to the system and Ontario consumers – an expected $700 million in benefits in the first 10 years alone.
