MISO plans to file in December to create separate but identical cost allocation designs for MISO Midwest and MISO South under its long-range transmission plan.

FERC has authorized a MISO settlement that will replace a rate schedule for use of transmission between its Midwest and South regions.

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.

MISO is testing a new cost-sharing plan for members that use the regional transfer limit linking its Midwest and South regions.
