MISO fired up the second phase of its long-range transmission planning by debuting a theoretical map of projects that proved divisive with stakeholders.

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.

MISO revealed a new market efficiency project cost allocation proposal that would stipulate local projects be reviewed on a local basis only.

MISO is circulating a cost allocation plan that would lower voltage thresholds but raise cost minimums on economically beneficial transmission projects.

MISO and its stakeholders are considering how to more accurately measure the potential benefits of proposed transmission projects.

‎MISO is proposing to change its rules for market efficiency projects to include cost allocation for transmission projects under 345 kV.
