MISO unveiled a first look at possible long-range transmission projects, igniting testy exchanges between stakeholders over the necessity of grid expansion.

MISO will draw on its new planning futures to build the first set of models that could result in the long-term transmission plan’s first projects.

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

SPP stakeholders once again took a crack to resolve a weighty issue in determining how futures will be considered in the RTO’s 2021 transmission plan study.

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

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.

MISO will allow stakeholders an additional month to file their opinions on the RTO’s draft 2021 transmission planning futures scenarios.

MISO released draft future scenarios that would reflect the increasingly dominant role clean energy resources will play in its planning process.

SPP stakeholders delayed a decision over the weighting of futures and the use of economic must-run modeling in the 2021 transmission planning assessment.

MISO spent much of 2019 preparing for a massive shift to renewable resources — and 2020 will herald much the same, RTO executives say.
