MISO and several stakeholders came to the defense of the RTO’s $21.8 billion, 24-project long-range transmission plan portfolio for the Midwest as five Republican states seek to repeal the projects’ approval.

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 asked FERC for a month to prepare a defense of its second long-range transmission portfolio, which is being challenged by five state commissions in the footprint.
