MISO is poised to close the door on summer with an almost 122-GW peak while issuing several capacity advisories for MISO South.

MISO announced that its first interconnection queue express lane application window turned up 47 projects at a little more than 26.5 GW of proposed new capacity, with natural gas generation accounting for about 20 GW.

FERC granted NextEra Energy’s request to waive certain rules under MISO’s tariff to allow the company to restart its Duane Arnold nuclear plant by the end of 2029.

The tone of Infocast’s 2025 Midcontinent Energy Summit was noticeably apprehensive compared with last year, owing to political and regulatory uncertainty, load growth ambiguity, fluctuating tariffs and a pending complaint against MISO’s long-range transmission plan.

A new attack on regional transmission planning threatens to unravel a decade of progress toward a more reliable, affordable, and interconnected electric grid, says Ted Thomas.

Members of the Organization of MISO States are divided on whether the organization should register comments in a FERC complaint that could fundamentally change the way MISO can plan its long-view transmission.

MISO members largely agreed that MISO’s new capacity auction structure — featuring individual seasonal auctions and a sloped demand curve — is better for the health of the system.

MISO might replace up to three members on its board of directors as they reach term limits at the end of 2025.
