Missouri Public Service Commission

JEFFERSON CITY---Spire Missouri, Inc. (Spire Missouri) natural gas customers will see rates change under a filing that will take effect on September 1, 2023. The change reflects an adjustment to the Weather Normalization Adjustment Rider (WNAR) which authorizes rate adjustments based on weather variations. The purpose of the WNAR tariff is to adjust revenues, either positive or negative, for differences between actual heating degree days and normal heating degree days.

The adjustment would increase the monthly bill of a residential customer using 100 Ccfs (10,000 cubic feet) of natural gas a month by approximately $1.51 for Spire East customers and $1.11 for Spire West customers.

Spire Missouri East provides natural gas service to approximately 664,523 customers in the City of St. Louis as well as the Missouri counties of St. Louis, St. Charles, Butler, Iron, Franklin, Jefferson, Madison, Crawford, St. Francois and Ste. Genevieve. Spire Missouri West provides natural gas service to approximately 537,047 customers in Andrew, Barry, Barton, Bates, Buchanan, Carroll, Cass, Cedar, Christian, Clay, Clinton, Dade, DeKalb, Greene, Henry, Howard, Jackson, Jasper, Johnson, Lafayette, Lawrence, McDonald, Moniteau, Pettis, Platte, Ray, Saline, Stone and Vernon counties.
