Spire Missouri Files Rate Case; Bills Could Rise 11-15%
St. Louis – November 02, 2026 -- Spire Missouri has filed a rate case with the Missouri Public Service Commission (PSC) that would raise the average residential gas bill by about 11% in western Missouri and 15% in eastern Missouri if approved as filed.
Western and eastern Missouri face different increases
Assuming current natural gas market conditions, the average western Missouri residential bill would climb about $10 per month. In eastern Missouri, the average residential bill would rise about $13 per month. New rates would take effect next fall, because the PSC typically completes its review within about eleven months of filing.
Spire Missouri serves more than 1.2 million customers in the state. President Steve Mills said the utility's focus is on delivering "affordable natural gas service" safely and reliably.
