State regulatory staff and MISO continued to debate  the potential billions in spending called for in the RTO’s long-range transmission plan.

MISO said its proposal to conduct transmission cost allocation separately for the South and Midwest regions is likely to be in place for up to four years.

Reliability and clean energy related public policies are increasing the need for and benefits of large-scale transmission to avoid increased electricity costs.

Divisions between MISO and MISO South stakeholders deepened over the RTO’s long-range transmission plan.

Stakeholders say it's ill-advised for MISO to propose separate cost allocation methods for long-range transmission projects in MISO South versus MISO Midwest.
