MISO announced it will honor a request from Texas regulators and include southeastern Texas in its first long-range transmission study for MISO South.

MISO said its first crack at long-range transmission planning in the South region likely would take about three years to culminate in potential project recommendations.

MISO will start evaluating its South region for long-term transmission needs in 2026, beginning with Louisiana, the RTO announced before its Board of Directors.

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.

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.

Five state public service commissions have banded together to request that FERC order a recasting of MISO’s long-range transmission projects, arguing the projects aren’t as beneficial as MISO has advertised.

The Southern Renewable Energy Association appeared before Entergy’s state regulators to urge them to think twice before considering leaving MISO for the Southeast Energy Exchange Market.

MISO leadership again promised to step up the RTO’s advance communication of tight system conditions following its four-hour load-shed directive for about 600 MW in Greater New Orleans.
