Illinois Commerce Commission staff have passed on recommending that Ameren and two smaller Zone 4 utilities depart MISO for PJM.

"The energy transformation will last decades, not years, which is why we are confident that investment opportunities will continue to strengthen and lengthen our rate base growth,” CEO Calvin Butler said.

The PJM Markets and Reliability Committee overrode concerns from Illinois consumer advocates and regulators to create a fifth cost of new entry area for the Commonwealth Edison region.

PJM's Markets and Reliability Committee and Members Committee will meet Oct. 25, with potential votes on creating a fifth cost of new entry area for the Commonwealth Edison zone in Illinois, the 2023 Reserve Requirement Study and capacity offers for generators with co-located load.

Staff from the Illinois Commerce Commission put their own spin on an analysis showing how much Ameren’s switch to PJM could cost MISO.

Voltus withdrew a demand response resource issue charge, while AEP and Dominion proposed a  capacity obligation issue charge.

Illinois Gov. JB Pritzker vetoed a measure that would have allowed incumbent utilities in downstate Illinois exclusive rights to build regional MISO transmission lines.

The Illinois Commerce Commission has instituted a notice of inquiry over the potential benefits of Ameren Illinois quitting MISO to join PJM.

Exelon utilities will work on transmission upgrades as the Brandon Shores coal-fired power plant prepares for deactivation.

PJM responded to Ohio legislators' concerns about the cost impact of Illinois' climate policy, saying it could not split Ohio out of related transmission planning and pledging to work with lawmakers going forward.
