Do you feel utility rate increases are becoming unaffordable for your household?
Flower Mound town council members approved a 14% rate increase for Atmos energy service. The new rates officially went into effect on Oct. 1.
Why it matters
GRIP legislation entitles gas utilities to request annual rate hikes to cover capital investments. Because municipalities have limited legal jurisdiction to intervene in these filings, Flower Mound opted to negotiate a smaller increase rather than challenge it at the Texas Railroad Commission.
Atmos rates have risen 57% over the last six years. Residential gas rates are currently increasing 50% faster than commercial gas rates.
The players
Flower Mound Town Council
This is the legislative body responsible for governing the town of Flower Mound and managing its utility agreements.
Atmos

Texas Railroad Commission
This state agency serves as the primary regulator for the oil and gas industry in Texas.

Timeline
September 21, 2026: The Flower Mound town council approved the Atmos rate increase.
October 1, 2026: The increased Atmos utility rate went into effect.
2020-2026: Atmos rates increased by a total of 57%.
Market Landscape
The town’s decision to negotiate directly follows the limited oversight authority granted to municipalities under the state’s GRIP legislation. This regulatory environment forces cities to rely on steering committees to mitigate costs that utilities would otherwise pass on to customers.
Residents will face higher monthly utility bills following the 14% increase. Because residential rates are rising 50% faster than commercial ones, homeowners will see a disproportionate impact on their household budgets.
The takeaway
Homeowners should anticipate continued cost pressures, as gas rates have risen significantly faster than general taxes in recent years. Residents are encouraged to monitor future public council meetings regarding the planned comprehensive review of Atmos tariff structures.
