Do you feel utility rate increases are becoming unaffordable for your household?
The Flower Mound town council approved a 14% increase in energy rates for Atmos customers that officially took effect on Oct. 1. This adjustment follows a period of repeated cost hikes for utility services in the region.
Why it matters
The increase follows state-level GRIP legislation, which entitles gas utilities to request annual rate hikes for capital investments while limiting municipal intervention power. Operators must now account for this rising overhead in their monthly operating budgets.
Atmos rates have risen 57% over the last six years, significantly outpacing the 4% tax increase recorded in Flower Mound during the same period. Under the new 14% hike, residential gas rates are rising 50% faster than commercial gas rates.
The players
Atmos Energy
A natural gas utility provider operating across Texas with the ability to request annual rate increases under state legislation.
Flower Mound Town Council
The local governing body in Texas that negotiates and approves utility rate changes for the city.
Texas Railroad Commission
The state regulatory agency that oversees energy utilities and holds ultimate authority over rate increase disputes.
The details
Flower Mound utilized the Rate Review Mechanism to negotiate the final increase, opting for this path to avoid a formal challenge before the Texas Railroad Commission where municipalities face limited jurisdiction. The town government now plans to seek a comprehensive review of Atmos tariff design to address long-term cost concerns. This shift forces local businesses to re-evaluate energy expenditures as they absorb the latest utility pricing adjustments.
Timeline
September 21, 2026: The Flower Mound town council approved the Atmos rate increase.
October 1, 2026: The 14% rate hike officially went into effect.
Market Landscape
This rate hike follows the standardized framework established by the Gas Reliability Infrastructure Program (GRIP) legislation. The development highlights the structural constraints on municipalities, which are increasingly limited to negotiation rather than broad intervention in utility pricing.
Business owners should review their most recent utility statements to reconcile the 14% increase against their current commercial energy contract terms. If the cost burden significantly affects margins, consult with your accountant regarding potential energy-efficiency tax credits or expense reallocation.
The takeaway
The town's reliance on the Rate Review Mechanism serves as a primary tool for controlling utility costs when GRIP legislation restricts local legal authority. Operators should monitor the progress of the town's upcoming comprehensive review of tariff design to understand potential future changes to the utility billing model.
