, with forecasted completion dates near the end of this decade. In addition, the MISO awarded three competitive bid projects to ATXI that represent a total estimated investment of approximately $220 million for ATXI. In 2024, Ameren Illinois and ATXI filed a request for a CCN, among other things, with the ICC related to the portion of the MISO long-range transmission projects they will construct within the ICC’s jurisdiction. A decision by the ICC is expected by mid-2025. In 2024, ATXI filed requests for CCNs, among other things, with the MoPSC related to the MISO long-range transmission projects that it expects to construct within the MoPSC’s jurisdiction. Decisions by the MoPSC are expected in 2025. Also in 2024, the MISO approved a first set of second tranche projects. A portion of these projects were assigned to Ameren and are estimated to cost approximately $1.3 billion, based on the MISO’s cost estimate. The first set of second tranche projects also includes competitive bid projects that are estimated to cost $6.5 billion, which includes projects located in Illinois that are estimated to cost $1.8 billion, based on the MISO’s cost estimate. The competitive bid process is expected to take place through 2026. In May 2025, the MISO and Ameren Services, on behalf of Ameren Missouri, Ameren Illinois, and ATXI, filed a request with the FERC to allow transmission rate incentives relating to the second tranche projects assigned to Ameren. If approved by the FERC, the incentives would allow construction work in progress to be included in rate base for projects constructed by ATXI, thereby improving the timeliness of cash recovery, and would allow recovery of prudently incurred costs, subject to FERC approval, for any portion of the projects if they are abandoned for reasons beyond the control of Ameren. If approved, ATXI would not capitalize allowance for funds used during construction on the related projects. A decision by the FERC is expected by the end of 2025. The MISO will conduct future long-range transmission scenario planning throughout 2025 and is expected to begin identifying a second set of second tranche projects as early as December 2025.
