MISO and the Tennessee Valley Authority are poised to strike an agreement on emergency energy transactions after months of RTO leadership complaining that TVA doesn’t return the favor of energy transfers in times of need.

Stakeholders appear wary of MISO’s proposed, availability-based accreditation it plans to file with FERC by the end of the year for the RTO’s approximately 12 GW of load-modifying resources.

The MISO Board of Directors hit the high notes of resource adequacy anxiety, a possible new member with experience at Southern California Edison and an annual budget that will creep past $400 million.

MISO said it managed a milder summer overall compared to previous years, though it weathered two hurricanes and escalated into emergency warnings during a heat wave.

At their quarterly meetup, MISO members largely agreed there won’t be an easy path to achieving decarbonization affordably for customers.

MISO’s quarterly public meetup with its board of directors put on display the unrelenting rift between the RTO’s planners and the Independent Market Monitor over MISO’s $21 billion in long-range transmission planning.

MISO said its second, mostly 765-kV long-range transmission plan will provide the Midwest region with at least a 1.9:1 benefit-cost ratio, a metric that was greeted with skepticism by Independent Market Monitor David Patton.

MISO and its transmission owners defended their practice of allowing TOs to self-fund network upgrades necessary to bring generation online before developers get the chance to finance them.

MISO’s new day-ahead market clearing engine should move into standalone production near the end of September following a delay in testing, RTO executives said.
