MISO will conduct a more thorough study of transmission capacity needs in the Upper Midwest in response to utilities behind the independent CapX2050 planning study.

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

Some regulators aren’t convinced about merging MISO’s transmission planning with interconnection studies, a move some say could improve cost effectiveness.

The 2020 MISO Transmission Expansion Plan contains 510 proposed projects at a combined $4.06 billion, the priciest since the RTO's 2011 MVP portfolio.

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

MISO defended its first storage-as-transmission proposal, maintaining the plan is a good interim measure while the RTO designs a permanent approach.

MISO presented stakeholders a long-awaited set of planning futures it insists are final despite calls for an additional scenario that models a downturn stemming from the COVID-19 pandemic.

FERC affirmed METC's 138-kV Morenci transmission project is a local distribution facility that should not be included in MISO's annual transmission plan.

MISO is mounting a third attempt to gain FERC approval to overhaul the cost allocation design for economic transmission projects after previous rejections.

MISO will use the recommendations of the Coordinated Planning Process Task Team to work on synchronizing the RTO's transmission planning and generator interconnection processes.
