Illinois’ climate goals could cost other states in PJM and MISO tens of millions in transmission upgrades as coal and natural gas power plants are retired.

PJM transmission owners led by Dominion presented the Transmission Expansion Advisory Committee with more than $400 million in supplemental projects.

MISO responded to criticism from Illinois lawmakers that it isn’t doing enough to bring renewables in its queue online to solve its capacity deficiency.

Sponsors of Illinois’ Climate and Equitable Jobs Act held a news teleconference to condemn “foot dragging” by MISO in getting new renewable energy online.

PJM stakeholders endorsed an update to the generation deactivation process as some members asked the RTO to slightly modify the proposed timing language.

MISO and PJM are assessing the need for an interregional study and transmission plan this year.

PJM provided an update at last week’s Operating Committee meeting on the Illinois Climate and Equitable Jobs Act and its impact on the RTO.

Illinois is decarbonizing its electric generation, and Minnesota is focusing on EVs and transit emissions, but Ohio is keeping a coal plant subsidy.
