The Illinois Commerce Commission (ICC) has launched an inquiry into Ameren Illinois' study evaluating the feasibility of transitioning from the Midcontinent Independent System Operator (MISO) to the PJM Interconnection (PJM). This move comes as MISO faces structural market issues, raising questions about resource adequacy and consumer costs.
ICC Chairman Doug Scott highlights the study's importance, stating it's essential to assess whether staying with MISO aligns with Illinois consumers' best interests.
Prompting the inquiry was MISO's 2022-2023 Planning Resource Auction, which revealed market deficiencies that could lead to energy shortages and higher utility bills in central and southern Illinois.
Ameren's study considers reliability, affordability, equity, and environmental impacts, aiming to guide the Commission's future decisions on grid operators.
Stakeholders can contribute during a three-month comment period starting with the inquiry. Initial comments are due by October 2, 2023, and reply comments by November 1, 2023.
The inquiry isn't a rulemaking process, but it could shape future Commission actions.
