MISO announced it will table the effort to analyze network upgrades and wait until the end of the year to see how its long-term transmission plan develops.

A study finds that MISO can reliably operate with a fuel mix heavy on renewables, but only if its members dramatically expand transmission.

MISO is sticking with its usual slate of transmission planning studies for 2021, opting not to include specially targeted analyses in MTEP 21

MISO released details on its long-term transmission plan, intended to adapt its grid to a rapidly evolving generation portfolio.

MISO is wrapping up its 2020 Transmission Expansion Plan and eyeing next year’s planning cycle, with more renewable energy predictions.

MISO members have recommended that the RTO’s 2020 Transmission Expansion Plan proceed to final approval in December.

MISO is juggling several transmission planning activities as it faces a cascade of new gigawatts in its interconnection queue.

MISO proposed requiring upgrades needed by generation projects to reach certain voltage and price levels before they can be tested for cost-sharing eligibility.

MISO temporarily backed off requiring load-serving entities to provide the location and capacity values of distributed energy resources for planning models.

MISO floated ideas on how it could better synchronize the studies supporting its annual transmission planning and generator interconnection queue processes.
