PSC Sets Intervention Deadline In Ameren Missouri Electric Fuel And Purchased Power Adjustment Charge Cases

April 10, 2023

Union Electric Company d/b/a Ameren Missouri has filed a request

with the Missouri Public Service Commission to adjust the fuel adjustment clause (FAC) charge on

the bills of its electric customers.

Ameren Missouri made two filings. In its first filing (Case No. ER-2023-0338), Ameren

Missouri proposes to adjust the FAC to reflect changes in its fuel and purchased power costs, net off-

system sales revenues and associated transportation experienced during the four month period of

October 2022 through January 2023. The second case is Ameren Missouri’s true-up filing (Case No.

EO-2023-0340).

According to the Ameren Missouri filings, the FAC for a residential customer using 1,017

kWh (kilowatt-hours) of electricity a month will drop from approximately $6.37 a month to

approximately $5.35 a month. The proposed change would take effect on June 1, 2023.

Applications to intervene and participate in these cases must be filed no later than April 21,

2023, with the Secretary of the Missouri Public Service Commission, P.O. Box 360, Jefferson City,

Missouri 65102, or by using the Commission’s Electronic Filing and Information System (EFIS) at
