Ameren Missouri customers and stakeholders have a few weeks to weigh in on several regulatory cases.

The Missouri Public Service Commission (PSC), which regulates the state's investor-owned utility companies, set a Dec. 22 intervention deadline for two cases, including one that would change Ameren's fuel adjustment clause (FAC) charge.

The FAC allows Ameren to pass changes in its net fuel and purchased power costs to customers outside of its regular triennial rate adjustment requests, the last of which was agreed to by the PSC over the summer.

According to a PSC news release, the FAC for a residential customer using 1,021 kilowatt hours of electricity per month would decrease from $3.15 a month to $2.60.

The proposal would take effect Feb. 1, if approved by the commission.

The other case revolves around Ameren's request to adjust its Energy Efficiency Investment Charge (EEIC), a charge to encourage companies to implement demand-side and energy efficiency programs. The charge appears as a separate line item on customer bills.

Ameren's filing said the EEIC will drop from $3.74 a month to $3.65 for most customers.

Customers can contact the Office of the Public Counsel at the Governor Office Building (200 Madison St., Suite 650, P.O. Box 2230, by phone at 866-922-2959 or via e-mail at [email protected]) or the PSC (P.O. Box 360, via phone at 800-392-4211 or e-mail at [email protected]).
