Missouri Public Service Commission

JEFFERSON CITY---The Missouri Public Service Commission has approved a change in the infrastructure system replacement surcharge (ISRS) for Liberty Utilities (Midstates Natural Gas) Corp. d/b/a Liberty Utilities (Liberty). The ISRS first appeared on customer bills in November 2008.

The ISRS adjustment reflects infrastructure replacement investments made by the natural gas company from April 1, 2018 through October 31, 2020. These costs for natural gas pipeline replacements and relocations are not currently included in Liberty’s rates.

In Liberty’s most recently completed general rate case (GR-2018-0013), ISRS rates were reset to zero effective July 1, 2018. As a result of this case, the ISRS for a residential natural gas customer in Liberty’s Northeast (NEMO) and West (WEMO) districts will be $1.00 a month. The ISRS for a residential natural gas customer in Liberty’s Southeast (SEMO) district will be $0.45 a month. The change is expected to take effect on June 1, 2021.

Liberty serves approximately 52,585 natural gas customers in Missouri. The NEMO service area includes the counties of Adair, Clark, Knox, Lewis, Macon, Marion, Pike, Ralls, Schuyler and Scotland. The WEMO service area includes the counties of Bates, Cass, Henry and St. Clair. The SEMO service area includes the counties of Butler, Cape Girardeau, Dunklin, Iron, Mississippi, New Madrid, Pemiscot, Ripley, Scott, Stoddard and Wayne.
