MISO this week said it will need to pause its long-range transmission modeling effort and correct two errors so that it has the clearest picture of future grid performance. Staff said the work will delay the release of reliability and economic models by a few weeks as they prepare a...

MISO unveiled a first look at possible long-range transmission projects Wednesday, igniting testy exchanges between stakeholders over the necessity of extensive grid expansion. The RTO released an indicative map of solutions meant to give stakeholders a rough idea of project needs that might be pursued later this year under its...

MISO is seeking ways to modify its annual transmission plan and make it easier for stakeholders to suggest alternatives to transmission owners’ project proposals. During a Planning Subcommittee meeting Feb. 9, the RTO tested a draft plan that would increase the amount of time stakeholders have to assess projects and...

MISO last week said it bit off more than it could chew by simultaneously mounting a long-term transmission package while trying to merge interconnection upgrades with annual transmission planning. Staff announced Wednesday during a Planning Advisory Committee (PAC) teleconference that it will table the effort to analyze network upgrades stemming...

A MISO study on renewables integration has found the grid operator can reliably operate its system with a fuel mix heavy on wind and solar energy, but only if its members engage in dramatic transmission expansion. The 216-page report concluded that reliable system operations "beyond the 30% system-wide renewable level...

MISO is sticking with its usual slate of transmission planning studies for next year, opting not to include specially targeted analyses in its annual package. Project Manager Sandy Boegeman said MISO intends to conduct the usual studies for the 2021 Transmission Expansion Plan (MTEP 21), despite a few specific requests...

MISO released details this week on its recently announced long-term transmission plan, saying its rapidly evolving generation portfolio signals a need for transmission tailored to handle the fleet of the future. (See MISO Readying Intensive Transmission Planning.) "First and foremost, I would call this a transmission planning study. … What...

MISO is wrapping up its 2020 Transmission Expansion Plan (MTEP 20) with an eye on next year’s planning cycle that contains more aggressive renewable energy predictions. MTEP 20 includes 514 projects costing slightly more than $4 billion. The most expensive project remains Ameren’s new Massac substation in Southern Illinois and...

MISO members have recommended that the RTO’s 2020 Transmission Expansion Plan (MTEP 20) proceed to final approval in December. Without discussion, eight of MISO’s 10 sectors with voting rights approved MTEP 20, comprising 514 new projects costing $4.06 billion, during the Planning Advisory Committee teleconference Wednesday. The portfolio investment level...

MISO is juggling several transmission planning activities as it faces a cascade of new gigawatts in its interconnection queue, stakeholders heard during this week’s Planning Week. The RTO announced a record number of new queue entrants in July, with customers submitting 353 applications representing about 52 GW of new generation.
