ICC adopts edited remand order, reduces Ameren transmission plant disallowance
Summary
On remand from the Fifth District Appellate Court, the Illinois Commerce Commission approved edits to Ameren's gas rate case that reduced the transmission plant disallowance from $47.51 million to $35.37 million and adopted selected staff recommendations affecting low-income rate provisions.
The Illinois Commerce Commission on April 23 approved an edited order on remand in Ameren's gas rate case, finding portions of the company's proposed maximum allowable operating pressure (MAOP) reconfirmation work unsupported and decreasing the transmission plant disallowance.
The order, approved without objection, adjusts the previously proposed transmission plant disallowance from $47.51 million to $35.37 million and directs a prudence review and rate adjustments consistent with the Fifth District Appellate Court's remand. The Commission also reviewed and adopted staff recommendations 1, 3 and 6 through 10 as minor changes to Ameren's Rider LICA (low-income credit adjustment), while declining staff proposals to remove self-verification, require LAAS to set discounts, or to mandate auto-enrollment in budget billing.
Commissioners also clarified that Ameren may remove customers who have self-verified as low-income from the program if the company presents substantiated evidence of misuse. The edited order implements the appellate court's directions and makes specific rate and program adjustments to ensure resulting rates are just and reasonable on remand.
Procedure and vote: a commissioner moved the edits and Commissioner Paradis seconded; the Commission asked for objections and, hearing none, approved the edits and the order on remand.
Why it matters: the decision reduces the financial disallowance that the utility initially faced, with direct implications for how costs are allocated and for customer rates. The ruling follows appellate instructions and reaffirms the Commission's role in reviewing prudence and program design for low-income rate treatment.
Next steps: the order on remand is effective as approved and the Commission record and attachments provide reconciliations and appendices supporting the adjusted figures.
