Spire Missouri natural gas customers will see rates change under a filing that is scheduled to take effect on September 1, 2022.

A news release says 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 WNAR adjustment would increase the average monthly bill of a residential customer using 100 Ccfs (10,000 cubic feet) of natural gas a month by $1.43 for Spire Missouri West customers.

Spire Missouri West provides natural gas service to approximately 533,000 customers in 29 counties, including Saline, Carroll, Howard, Johnson, Lafayette, and Pettis in the KMMO listening area.
