MISO is putting the final touches on its most expensive annual transmission investment package after a final round of planning meetings.

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

MISO’s first rule set for storage resources functioning as transmission assets passed muster with FERC, though James Danly opposed the plan.

The MISO Advisory Committee adopted the first set of standards for creating and joining stakeholder sectors and discussed the coordination of transmission planning.

MISO said it foresees hundreds of gigawatts in mostly carbon-free resource additions by 2040, according to its new transmission planning future scenarios.

FERC ordered hearing and settlement procedures on ATSI’s request to recover $154 million, including costs related to its move from MISO to PJM in 2011.

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.
