JEFFERSON CITY—Spire Missouri, Inc. (Spire Missouri) natural gas customers in the eastern half of Missouri will see rates increase starting September 1, 2022.
The rate hike 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 average monthly bill of a residential customer using 100 Ccfs (10,000 cubic feet) of natural gas a month by $2.08 for Spire Missouri East customers and $1.43 for Spire Missouri West customers.
Spire Missouri East provides natural gas service to approximately 663,000 customers in the City of St. Louis as well as the Missouri counties of Ste. Genevieve, St. Louis, St. Charles, Butler, Iron, Franklin, Jefferson, Madison, Crawford, and St. Francois.
