Rate Request



2023 Rate Request

The 2023 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 2022 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 2023 of $99.90 as compared to December 2022 of $115.11


January 2024 of $126.43 as compared to January 2023 of $155.46.


February 2024 of $113.54 as compared to February 2023 of $128.11.

Current natural gas costs reflect the impact of the current available supply and demand this winter heating season. Chattanooga Gas does not profit from these costs of gas 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 48% of a typical residential customer’s bill.
