MISO is once again evaluating the effectiveness of the rules behind its scarcity pricing just three years after shelving a similar effort.

The MISO stakeholder community appears to support the RTO’s plan to extend the current arrangement on Midwest and South transmission flows.

MISO said it will begin hunting for solutions to mitigate the gap between LMRs that clear capacity auctions and what actually happens in emergencies.

FERC asked MISO to remove or defend its requirement that distribution utilities and load-serving entities report real-time grid injections and withdrawals to be compliant with Order 841.

MISO said it quickly regained control during its first maximum generation emergency July 7 during a lasting heatwave.

MISO and SPP regulators are close to asking the RTOs for improvements to transmission operations on their seam as their market monitors wind down a study.

MISO won FERC approval to create an 11th stakeholder sector for hard-to-categorize members despite some misgivings about the equity of the new arrangement.

FERC rejected transmission customers’ complaint over MISO’s seven-year-old cost allocation plan for baseline reliability projects.

The third time’s a charm for MISO getting FERC approval of its sweeping, cost-allocation overhaul for large economic transmission projects.

MISO reiterated it can likely reliably operate the grid with a 50% renewable energy mix but warned certain variables could send energy prices soaring.
