¶ 1 In January 2012, Ameren Illinois Company (Ameren) filed its initial application with the Illinois Commerce Commission (Commission) to establish a performance-based rate tariff under the authority of section 16-108.5 of the Public Utilities Act (Utilities Act), commonly referred to as the Energy Infrastructure Modernization Act (Modernization Act) (220 ILCS 5/16-108.5 (West 2012)), enacted by Public Act 97-616 (Pub.

¶ 2 In April 2012, Ameren filed its first annual update with the Commission. In December 2012, the Commission reaffirmed the aforementioned findings.
¶ 3 On appeal, Ameren asserts the Commission made three reversible errors in reaching its decision, including (1) considering the capital structure of Ameren's holding company rather than the actual capital structure of Ameren when determining rate base; (2) reducing Ameren's rate base by ADIT for projected plant additions; and (3) decreasing Ameren's rate base by unused vacation pay accrued by Ameren employees.
¶ 4 We affirm.
