2025 Documents
What's Changing & Why
CoServ Gas filed a request for an Interim Rate Adjustment to increase the customer charge used to calculate the customer’s monthly bill with the Railroad Commission of Texas on July 18, 2025.
The increase can be attributed to the increased overall capital investment since the last rate filing in July of 2023. From 2023 to 2025, we have seen inflationary pressure on costs related to the investment in capital infrastructure, including materials and labor costs.
However, our rates – and your bill – will still be lower than with other natural gas providers in North Texas.
