Rate Schedules & Tariff Analysis
Mid-Tex C&I rates combine a fixed monthly customer charge with volumetric commodity charges (per Ccf for commercial, declining-block per MMBtu for industrial/transportation), layered with pass-through riders. The dominant cost driver for most customers is Rider GCR (gas cost recovery), which fluctuates monthly with market gas prices and is not a margin item for Atmos.
Atmos Energy Corporation Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate C – Commercial Sales | Commercial; $94.01/mo customer charge + $0.22261/Ccf commodity (eff. 10/01/2025) |
| Rate I – Industrial Sales | Industrial < 200 MMBtu/day; $1,848.75/mo + declining-block MMBtu charges |
| Rate T – Transportation | Customer-supplied gas; same charge structure as Rate I plus upstream transport recovery |
Atmos Energy Corporation Rate Features & TOU Details
- Fixed customer charge plus volumetric commodity charge
- Declining-block pricing rewards higher industrial volumes
- Rider GCR passes gas commodity cost through at no margin
- Weather Normalization Adjustment (WNA) smooths winter/summer bills
- Rider CEE funds conservation/energy-efficiency programs
- No demand charges; transportation customers can self-supply gas

Atmos Energy Corporation Data Access FAQ
Does Atmos Energy support Green Button or a public API for my commercial accounts?▾
No. Atmos does not offer Green Button Download My Data, Connect My Data, ESPI, or a public developer API. C&I customers access data through Account Center and the Customer Activity Website (CAW); programmatic access is achieved through Nectar, which provides API access to this utility's billing and usage data — see docs.nectarclimate.com.
How does a large commercial or industrial customer get detailed usage reports?▾
Large-volume customers register for the Customer Activity Website (CAW) by submitting the request form to onlinUAR@atmosenergy.com. After approval (2-5 business days), CAW provides monthly usage and billing reports back to July 2019, with older data available on request.
What rate schedule will my business be on in Texas (Mid-Tex)?▾
Most commercial sites and small industrial users (under 30,000 Ccf/year) take Rate C: $94.01/month customer charge plus $0.22261/Ccf (effective 10/01/2025), plus pass-through riders. Industrial customers under 200 MMBtu/day take Rate I with a $1,848.75/month charge and declining-block MMBtu pricing; larger loads require a special contract.
Can my industrial facility buy its own natural gas?▾
Yes. Eligible large customers directly connected to the Mid-Tex system can take Rate T (Transportation), paying Atmos the same delivery blocks as Rate I while supplying their own gas under a Transportation Agreement. Customers with maximum daily demand of 1,000 MMBtu or more and a load factor of 10% or less are not eligible.
How often do Atmos Mid-Tex rates change?▾
Annually. Mid-Tex files under the Rate Review Mechanism (RRM); the 2025 settlement raised system-wide revenue by $205.6 million effective 10/01/2025 (about $7.83/month for the average residential customer). The next RRM filing is expected in 2026 with new rates around October 1.
Can I get interval (sub-daily) gas data from Atmos?▾
No. Where wireless meters are deployed, Atmos provides daily usage graphs in Account Center, but it does not offer 15- or 30-minute interval data.
