Ameren Missouri filed a proposal with the Public Service Commission for a rate hike to improve its electric and natural gas systems. The new rates would take effect in 2022 to reflect major upgrades to electric and natural gas system reliability and resiliency for customers, as well as investments to support the transition to cleaner energy for the benefit of customers and local communities. If approved by regulators, the rate adjustment in 2022 would cost an average electric customer about $12 a month (based on approximately 1,029 kilowatt-hours of usage per month). For Ameren Missouri’s natural gas customers, largely located in central and southeast Missouri, the adjustment in base rates would cost about $4 a month for the average residential customer. If approved, the new electric rate request reflects a 5.4% total increase over an almost five-year period, a yearly average of approximately 1%.
