The Missouri Public Service Commission has approved a request filed by Spire Missouri, Inc. to change the Infrastructure System Replacement Surcharge (ISRS) on the bills of its natural gas customers. The ISRS first appeared on Spire West customer bills in April 2004.

This ISRS adjustment reflects infrastructure replacement investments made by the natural gas company during the period of March 1, 2023 through August 31, 2023. These costs for natural gas pipeline replacements and relocations are not currently included in Spire Missouri’s rates.

For Spire West residential customers, the current ISRS is $0.59 a month. As a result of this case, the ISRS will increase to $1.79 a month.

Spire West provides natural gas service to approximately 537,047 customers in Carroll, Howard, Johnson, Lafayette, Pettis, and Saline counties in the KMMO listening area.
