ERCOT has filed with the Texas PUC a report ("Summary of Multi-Interval Real-Time Market (MIRTM) Feasibility Study") which concludes that "ERCOT and stakeholders find that the MIRTM study demonstrates that the estimated costs are in excess of the measured benefits and therefore insufficient to support a recommendation to move forward with MIRTM at this time."

ERCOT notes that, while the report concludes moving forward with MIRTM at this time is not appropriate, future market conditions may change, and the report will provide valuable information for any future consideration of the issue

Texas PUC Commissioner Kenneth Anderson, speaking on the expected conclusion of the study, had said at a recent open meeting that, with the report's conclusion likely ending consideration of multi-interval SCED for now, "that then opens up the question about going ahead and co-optimizing the real-time market."
