Commercial electricity and gas rates, energy market structure, regulations, and utility providers for property managers operating in Missouri.
Missouri has a regulated electricity market served by Ameren Missouri (eastern Missouri including St. Louis) and Evergy (Kansas City metro). Commercial customers cannot choose their electricity supplier. The Missouri Public Service Commission regulates rates and utility operations.
What this means for property managers:
In Missouri's regulated market, your utility provides both generation and distribution at rates set by the state public utility commission. While you cannot choose your electricity supplier, you can optimize costs through rate schedule analysis, demand management, and participation in utility efficiency programs.
Rates are set by the public utility commission. No supplier choice available.
Rising
Ameren Missouri rates increasing due to coal plant retirements and wind generation investment. Evergy rates rising from grid modernization costs. Both utilities filing for 5-8% increases in 2025-2026.
Missouri has no statewide energy benchmarking mandates. St. Louis has adopted Building Performance Standards requiring commercial buildings to meet energy performance targets, making it one of the few cities in the Midwest with mandatory building energy requirements. Kansas City has adopted a Climate Protection and Resiliency Plan with voluntary commercial building provisions.
