Ameren Missouri Granted CCN
for Generation Facility in Cass County, Illinois

JEFFERSON CITY---Union Electric Company d/b/a Ameren Missouri filed an application with the Missouri Public Service Commission on June 16, 2023, seeking a certificate of convenience and necessity (CCN) related to four solar generations: (1) a 300 megawatt (MW) solar generation facility to be constructed in Warren County, Missouri (Split Rail Solar Project); (2) a 150 MW solar generation facility to be constructed in Cass County, Illinois (Cass County Solar Project); (3) a 50 MW solar generation facility to be constructed in Audrain County, Missouri (Vandalia Solar Project); and (4) a 50 MW solar generation facility to be constructed in Pike County, Missouri (Bowling Green Solar Project).

The CCNs for the Split Rail Project, Vandalia Project and Bowling Green Project were approved, with conditions, by the Commission on March 21, 2024. The signatories — Ameren Missouri, the Staff of the Commission (Staff), and the Office of the Public Counsel (OPC) — agreed that the Commission should not grant a CCN at that time for the Cass County Project until a condition set out in the Agreement was satisfied. The signatories further agreed, that, should the condition of the Agreement be satisfied, the Commission should grant Ameren Missouri a CCN for the Cass County Project. In May 2024, Ameren Missouri made two filings that the condition had been satisfied.

According to the application, the Cass County Project is to be constructed using a development-transfer structure under a Purchase and Sale Agreement (PSA) between Ameren Missouri and Savion, LLC. Once construction is complete, the project company will be merged into Ameren Missouri, which will be the surviving entity.

“After reviewing the application, the Agreement, Ameren Missouri’s two May filings in this matter, and Staff’s unopposed recommendation filed on May 23, 2024, the Commission finds that the Tartan criteria have been satisfied for the Cass County Project,” the Commission stated.

Ameren Missouri serves approximately 1.2 million electric customers in Missouri.
