Utilities that affect your install
Electric delivery in Fort Worth is Oncor Electric Delivery for most addresses, with CoServ Electric, Tri-County Electric Cooperative and United Cooperative Services in parts of the city. The boundary runs through neighborhoods, so two houses on one street can have different providers, and each approves a service-entrance tie-in its own way. Your bill shows which you have.
Natural gas is Atmos Energy Mid-Tex, CoServ Gas or SiEnergy, depending on the address. If the meter cannot carry the generator on top of the furnace, water heater and other appliances, the utility has to upsize it, which is a separate request with its own timeline. How gas line sizing works.
Already have solar? It has to connect on the utility side of the transfer switch so the generator never feeds the inverters, and the disconnect and meter rules come from Oncor Electric Delivery or CoServ Electric or Tri-County Electric Cooperative or United Cooperative Services, whichever serves your address. Why, and how the main DFW utilities handle it.

Generator questions from Fort Worth homeowners
How much does a whole house generator cost in Fort Worth?
A typical 20kW Cummins system installed in Fort Worth is estimated at $13,500 to $17,000, including the pad, transfer switch, permit and commissioning, with the gas line included as its own line item. Estimate only. Every installation is different; a site visit is required to determine whether your installation will cost less or more than this estimate. The RS20A unit itself is $5,925.25. Your figure depends on the distance from the generator to the gas meter and the electrical panel and on whether the gas meter needs upsizing, so it is fixed in writing after a free survey.
Do I need a permit for a generator in Fort Worth?
Yes. Permits go through Development Services Department; the published fee is priced by capacity rather than a flat fee — $6.10 up to 10kW, $9.85 to 20kW, $19.75 above, plus a service or subpanel charge. We pull the permit and meet the inspector, and it is inside the installation quote.
Can Fort Worth regulate my home generator install?
Only within limits. Texas Local Government Code § 229.102 bars a city from regulating the installation or inspection of a residential backup system of 50kW or less where the city does not own the electric utility. Since 2025, Texas Local Government Code § 247.0025 also lets a qualified third party do the plan review and inspection, and the city must then issue the permit by the third business day after notice.
Who provides gas and electric service in Fort Worth?
Electric delivery is Oncor Electric Delivery for most addresses, with CoServ Electric, Tri-County Electric Cooperative and United Cooperative Services in parts of the city. Natural gas is Atmos Energy Mid-Tex, CoServ Gas or SiEnergy, depending on the address. The electric utility sets how the transfer switch ties in at the meter; the gas utility decides whether your meter can carry the generator's extra demand. Service territory does not follow city limits, so we confirm both from your bill before quoting.
