Missouri Public Service Commission

JEFFERSON CITY---Union Electric Company d/b/a Ameren Missouri (Ameren Missouri) has filed an application with the Missouri Public Service Commission seeking Commission approval of a Missouri Energy Efficiency Investment Act (MEEIA) plan filed on March 27, 2023.

The proposed plan includes a Demand-Side Investment Mechanism (DSIM) and a Demand- Side Management Portfolio Plan. This is Ameren Missouri’s fourth MEEIA related program filing (MEEIA 4). The proposed plan would be effective for the period of January 1, 2024 through December 31, 2026.

Applications to intervene and participate in this case must be filed no later than April 11, 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 www.psc.mo.gov.

Individual citizens wishing to comment should contact either the Office of the Public Counsel (Governor Office Building, 200 Madison Street, Suite 650, P.O. Box 2230, Jefferson City, Missouri 65102-2230, telephone 1-866-922-2959, email opcservice@opc.mo.gov) or the Public Service Commission Staff (P.O. Box 360, Jefferson City, Missouri 65102, telephone 1-800-392-4211, email pscinfo@psc.mo.gov). The Office of the Public Counsel is a separate state agency that represents the general public in matters before the Commission.

MEEIA was passed by the Missouri legislature and signed into law in August of 2009. The purpose of MEEIA is to encourage investor-owned electric utilities to develop and implement demand-side management programs, which are commonly called energy efficiency programs or demand response programs.

On December 5, 2018, the Public Service Commission approved an agreement reached by parties in the case regarding Ameren Missouri’s current MEEIA plan (MEEIA 3). The Commission later approved a request to extend the MEEIA 3 plan through December 31, 2023.

Ameren Missouri provides electric service to approximately 1.29 million customers in Missouri.
