PSC Sets Intervention Deadline in Ameren Missouri Electric
Fuel and Purchased Power Adjustment Charge Cases

JEFFERSON CITY---Union Electric Company d/b/a Ameren Missouri has filed a request with the Missouri Public Service Commission to adjust the fuel and purchased power adjustment charge (FAC) on the bills of its electric customers.

Ameren Missouri made two filings. In its first filing (Case No. ER-2021-0328), Ameren Missouri proposes to adjust the FAC to reflect changes in its fuel and purchased power costs, net offsystem sales revenues and associated transportation experienced during the four month period of October 2020 through January 2021. The second case is Ameren Missouri’s true-up filing (Case No. EO-2021-0329).

As a result of these two filings, the FAC for a residential customer using 1,023 kWh (kilowatt-hours) of electricity a month would increase from approximately $0.27 a month to $3.15 a month. The proposed change would take effect on June 1, 2021.
