development and filing of the 2025 Electricity Procurement Plan, the ICC has approved the plan's proposal for multiple IPA procurement events over the following year. These events will procure portions of Ameren Illinois' energy and capacity forecasted requirements for forward delivery years through May 2028. Ameren Illinois has also entered into ICC-approved contracts for zero emission credits through May 2027 and for renewable energy credits with various terms, including contracts with 20-year terms ending 2032, and contracts entered into beginning in 2018 through 2024 with 15- to 20-year terms.

The projected required supply of these commodities could be significantly affected by changes in our assumptions about customer demand for electricity and natural gas supplied by us and inventory levels, as well as Ameren Missouri’s generation output, among other matters.
