The Missouri Public Service Commission has approved a filing made by Union Electric Company d/b/a Ameren Missouri to adjust the fuel and purchased power adjustment charge (FAC) on the bills of its electric customers.

A news release says Ameren Missouri made two filings with the Commission. In its first filing (Case No. ER-2021-0159), Ameren Missouri proposed 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 June 2020 through September 2020. The second filing was Ameren Missouri’s FAC true-up (Case No. EO-2021-0160).

For a residential customer using 1,000 kWh (kilowatt-hours) of electricity a month, the FAC will change from a current credit of approximately $1.89 a month to approximately $0.26 a month. The change is expected to take effect on February 1, 2021.

Ameren Missouri provides electric service to approximately 1.2 million electric customers in Missouri.
