Spire Missouri, Inc. (Spire Missouri) natural gas customers will see rates drop under a company filing that took effect on Tuesday.
The reductions reflect a change in the Weather Normalization Adjustment Rider (WNAR) which authorizes rate adjustments based on weather variations. The WNAR projects anticipated gas usage changes due to weather that is either warmer or colder than normal. The rate reductions in this filing generally reflect a colder than normal period for Spire's rate districts for the six month period ending July 31, 2019.
The establishment of a WNAR was part of a March 2018 Public Service Commission decision in a general natural gas rate case filed by Spire Missouri. Under the WNAR, Spire Missouri will make adjustments based on the weather twice a year.
Under tariffs filed by the natural gas company, a Spire East residential customer using 100 Ccf of natural gas in a given billing month will see a line item reduction of $1.66 in their bill, which is an additional $0.72 reduction in their bill from the current WNAR rate. A Spire West residential customer using 100 Ccf of natural gas in a given billing month will see a line item reduction of $1.37 in their bill, which is an additional $0.80 reduction in their bill from the current WNAR rate.
