Rate Request



2022 Rate Request

The 2022 ARM filing seeks to recover through rates $6.8 million in spent capital and recovery of the costs of work we’ve already done in 2021 to meet the region’s growing demand for natural gas service.

Rate Comparisons

The average Chattanooga Gas residential customer may expect to see an average total bill for the upcoming winter months as follows:


December 2022 of $125.56 as compared to December 2021 of $100.74


January 2023 of $167.05 as compared to January 2022 of $133.47


February 2023 of $158.54 as compared to February 2022 of $121.54.

Current natural gas costs reflect the impact of supply constraints and higher demand this winter heating season. Chattanooga Gas does not profit from these increased costs and instead passes on the market cost directly to customers. The current per therm price customers pay for natural gas delivered by Chattanooga Gas comprises approximately 70% of a typical residential customer’s bill due to economic factors that have affected the commodity’s market price.
