Spire Missouri, Inc. has filed an application with the Missouri Public Service Commission seeking to adjust the infrastructure system replacement surcharge (ISRS) on the bills of its Spire West natural gas customers. The surcharge first appeared on customer bills in 2004.

Spire seeks the adjustment to reflect infrastructure replacement investments made by the natural gas company since October 1, 2022. These costs for natural gas pipeline replacements and relocations are not currently included in Spire’s rates.

In Spire’s most recently completed general rate case (GR-2022-0179), ISRS rates were reset to zero effective December 26, 2022. In this case, the proposed monthly ISRS for a residential customer in Spire West is $0.69.

Applications to intervene and participate in this case must be filed no later than January 26, 2023, with the Secretary of the Missouri Public Service Commission.

Spire Missouri West provides natural gas service to approximately 527,200 customers in 31 counties, including Saline, Carroll, Cooper, Howard, Johnson, Lafayette, and Pettis in the KMMO listening area.
