Whole-Home Standby Power in Stephenville, TX
A city that draws its water from thirty-five wells, surrounded by a county where three quarters of homes heat with electricity. Two very different backup power problems, ten minutes apart.

The place
This town does not drink from a lake. It pumps.
The city states that its water supply uses 35 wells in the Trinity Aquifer, blended with treated water from the Upper Leon River Municipal Water District under a 50-year long-term supply plan, and that the state rates the supply Superior. That is an unusual amount of detail for a municipal water page, and it tells you something about how the place thinks.
It also tells you something about electricity. Thirty-five wells means thirty-five pumps, and pumps run on power. The same logic applies at household scale on every ranchette outside the city limits, where the well is private, the septic system is on site, and the pump is the first thing that stops when the meter does. That pump is also the largest starting load in the system design.
Tarleton State University has anchored the town since 1899, when Stephenville College was renamed for the rancher John Tarleton, and it has been part of the Texas A&M University System since 1917. Enrollment passed 21,000 in autumn 2025, a record for the sixth consecutive year. The city also hosts the Cowboy Capital of the World PRCA Rodeo, and Tarleton’s rodeo team has won eight national championships. A student body of that size in a city of roughly 22,000 explains most of the housing data below.
Two markets
Inside the city, rentals and new build. Outside it, land.
The same county, ten minutes apart, and almost nothing in common on a site visit.
In town
- 9,095 housing units, 57.3 percent single-unit detached
- 44.3 percent owner-occupied, the lowest share we serve
- Median year built 1984, with 21.3 percent built since 2010
- Median value $241,300
- 27.1 percent heat with Atmos piped gas
Municipal water and sewer, an Atmos meter on some streets and not others, and a lot of buildings that are somebody’s investment rather than somebody’s home.
Out of town
- 14.7 percent of county housing is manufactured
- Only 16.7 percent of county households heat with piped gas
- 74.8 percent heat with electricity
- 264 new septic authorizations countywide in 2025
- Median county home value $269,100, above the city
Private wells, on-site sewage, propane tanks, long service drops and, on the working properties, livestock that does not wait for a crew. Those get scoped like commercial standby jobs, because that is what they are.
That second column is the reason sizing matters more here than the brochure suggests. An all-electric house with a submersible pump has a materially higher backed-up load than a gas-heated house of the same size, and the county heats with electricity at nearly three times the rate the city does.
The co-op
United Cooperative Services was born in this county
Half the people reading this still call it ECEC. Erath County Electric Cooperative merged with Johnson County Electric Cooperative in April 2000 to create United Cooperative Services, so the co-op serving the county roads out here is, in a real sense, the county’s own utility grown up. It runs nearly 9,300 miles of line to about 105,000 customers, which works out to roughly eleven customers per mile.
Thinly loaded rural feeders are the ones that take longest to restore, and the numbers reflect it. In 2021, United reported an average of 811.3 minutes off per customer, about 13.5 hours; in 2024 it was 111.8 minutes, one of the better figures in the state. Oncor reported 558.8 minutes in 2021 and 532.5 in 2024. Both file those numbers with the federal government, and both include major storm days.
Storms here are not hypothetical either. On 19 April 2025 the National Weather Service confirmed an EF-1 tornado in this county with peak winds near 110 mph, on the same day as a confirmed EF-1 in Parker County. Restoration works from transmission down to individual service lines, which is correct engineering and cold comfort at the end of a long tap.

Common questions
Stephenville and Erath County questions
Utilities, fuel, rental property and the dairy question, which nobody else seems to answer.
Am I on Oncor or on the co-op?
Three utilities file Erath County service territory with the U.S. Energy Information Administration: Oncor Electric Delivery, United Cooperative Services and Texas-New Mexico Power. Inside town it is usually Oncor, in the deregulated market, so a retail provider bills you and Oncor restores you. Out on the county roads it is often United, where you are a member rather than a customer and there is no retail plan to shop. United keeps an office here, which is a clue to how much of this county sits on its lines.
Is it still Erath County Electric Cooperative?
Not since April 2000, when Erath County Electric Cooperative consolidated with Johnson County Electric Cooperative to form United Cooperative Services. Plenty of people here still say ECEC, and everyone knows what they mean, but the entity itself became United a quarter of a century ago. It now serves 14 counties with roughly 110,000 meters and nearly 9,300 miles of energized line, run out of Burleson with a member office in this city.
Why is Winter Storm Uri on my co-op bill?
Because United was a member of Brazos Electric, the wholesale supplier that filed Chapter 11 in March 2021 after ERCOT invoiced it $2.1 billion for the storm week. United’s share settled at roughly $440 million and was securitized as $451 million in bonds sold in December 2022. Members began repaying it in January 2023 through a line item called the Power Cost Recovery Factor, initially 1.17 cents per kilowatt hour, spread over about 28 years. A generator does not remove that charge; it changes what happens the next time the line comes down.
I own rental property here. Does that change the install?
It changes the priorities. Only 44.3 percent of housing units in this city are owner-occupied, the lowest share anywhere in our service area, and the detached-house share is the lowest too at 57.3 percent, which is what a university town looks like in a data table. For rental and small multifamily work, the conversation is usually about protecting the building rather than the comfort of a specific tenant: freeze protection, sump and lift pumps, life-safety lighting, and a transfer switch arrangement that does not depend on anyone being home.
What fuel will my generator run on outside town?
Almost certainly propane. Only two communities in the entire county have an investor-owned gas distribution utility: this city and Dublin, both on Atmos Mid-Tex. County-wide, just 16.7 percent of households heat with piped gas while 7 percent burn bottled propane and 74.8 percent heat with electricity. Where your driveway ends decides what your generator burns, and outside the certificated area it is a tank, sized for a multi-day run rather than for a barbecue season.
Do you handle dairy and agricultural standby power?
Yes, and it is a different design conversation. A dairy that loses power loses the milking parlour, the vacuum system and the bulk tank cooling, which turns an outage into a direct financial loss rather than an inconvenience. The USDA counted 58,000 milk cows in this county in 2023. Those installations get scoped like commercial work: transfer switch selection, prioritized circuits, and honest talk about what the machine will and will not carry.
