Update: Illinois Regulators Approve Nicor Gas Rate Case Settlement
Last month, I shared news about a proposed settlement in Nicor Gas’s rate case. Yesterday, the Illinois Commerce Commission formally approved that agreement.
The result? Nicor Gas will receive an annual base rate increase of approximately $81.6 million, substantially less than the $213.6 million originally requested.
The Commission also approved provisions addressing residential customer charges, pipeline investment alternatives, and future cost-allocation studies.
But the Order contains another interesting takeaway.
The Commission reminded utilities and other participants that negotiated settlements need to be submitted early enough to allow meaningful regulatory review. Even when parties agree, the Commission must independently determine whether the resulting rates are just and reasonable.
It’s an important distinction, and one that matters for utility customers throughout Illinois.
The Final Order was issued October 15, 2026, in ICC Docket No. 26-0099.
