Summary
Ameren Corporation, through its subsidiary Ameren Illinois Company, has filed a request with the Illinois Commerce Commission (ICC) to increase annual revenues for natural gas delivery service by approximately $160 million. This filing represents a significant request aimed at recovering infrastructure investments and ensuring a reasonable return on equity. The proposed increase is based on a 10.7% return on common equity and a capital structure of 54% common equity, with a rate base of $2.9 billion. Notably, Ameren Illinois is utilizing a 2024 future test year to mitigate regulatory lag, a common concern for utilities. A decision from the ICC is anticipated by December 2023, with potential new rates taking effect in January 2024. While the company is seeking this increase, the exact amount of approved rate changes and their sufficiency to cover costs and earn a reasonable return remain uncertain pending the ICC's decision.
