MISO made several maneuvers in 2022 to position itself for a majority-renewable portfolio while attempting to take the sting out of a rising capacity deficit.

The Memphis Light, Gas and Water Board of Commissioners unanimously rejected a 20-year, rolling power supply contract with the Tennessee Valley Authority.

FERC has denied a Tenaska complaint alleging that grid operators adopted operating guides, resulting in unduly discriminatory curtailment for its wind farm.

FERC upheld its prior ruling blocking MISO transmission owners from electing to self-fund network upgrades needed for merchant HVDC lines.

FERC continues to sanction MISO’s separate-but-equal postage stamp rate that is divided between its Midwest and South regions for major transmission buildout.

MISO and PJM will opt for one small interregional project this year through their Targeted Market Efficiency Project study.

The coming decade will see “extraordinary reliability challenges and opportunities” amid rapid changes in the North American electric grid, NERC staff said.

MISO and SPP announced that they will not pursue any small interregional projects next year from their first Targeted Market Efficiency Project study.

In a workshop, FERC commissioners and stakeholders debated the pros and cons of requiring minimum transfer capability between regions to promote reliability.

MISO and SPP have again come up empty in their fifth effort to find interregional projects to solve congestion along their seams.
