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, lower costs for consumers and new opportunities for market participants. MRP will help create a stable and efficient marketplace that produces value for consumers by encouraging competition and innovation.
