Josephine, Texas electricity: only part of town can choose a provider
Part of Josephine is on the competitive market and part isn't, so the first question for any Josephine address is whether Oncor or another utility serves it.
Last updated . Written by Power Hopper. Reviewed by Brent Ward, founder, on 2026-10-19. Data as of October 5, 2026 (meters) and October 19, 2026 (plan prices).
In short: ERCOT counts 1,049 active residential meters with a Josephine address, all on Oncor's wires (October 5, 2026).

Weather and electricity in Josephine
Typical weather near Josephine, from the nearest NOAA station with a complete 1991-2020 record: Lavon Dam, about 10 miles from the city center (station elevation 510 ft). These are normals for that station, not readings at your address. August is the warmest month on average, with a normal daily high of 93°F; January has the coolest average low, 34°F. Average daily highs reach 90°F or more in July to August. No month averages a daily low at or below freezing.
For electricity, the normals point to two seasons that can lift a household's usage: cooling-degree days (a measure of how far each day's mean temperature sits above 65°F) peak in August at 563 for the month, and heating-degree days (below 65°F) peak in January at 653. How much that matters to a bill depends on the home, its insulation, its heating fuel and the household, so use your own usage history, not a regional average, when you compare plans.
| Month | Avg high °F | Avg low °F | Precipitation (in) | Cooling degree-days | Heating degree-days |
|---|---|---|---|---|---|
| Jan | 54 | 34 | 2.6 | 1 | 653 |

Reference only: the U.S. Energy Information Administration's 2020 Residential Energy Consumption Survey puts the average Texas household at about 13,440 kWh a year (about 1,120 kWh a month if spread evenly). That is a statewide average for 2020, not Josephine, and not an estimate for your home. EIA source.

Common questions about electricity in Josephine
Can Josephine residents pick their own electric company?
Some can: 1,049 Josephine-addressed homes are on the competitive market, against about 1,844 city households. Many others likely belong to an electric co-op and can't choose. Addresses in 75173, 75442, 75189, 75135 (all split) need an exact-address check before you shop.
What is the biggest Josephine ZIP code for electricity customers?
75173. It holds 521 Josephine-addressed competitive homes; counting every address in the ZIP, ERCOT has 2,422 meters for roughly 3,346 households, a 0.72 ratio.
Are electric bills high in Josephine?
Depends on the part of town. The ACS 2020-2024 found 55.3 percent of 75164 households paying over $250 a month for electricity and 44.4 percent in 75442. Home size, age and electric heating drive most of that gap, so compare plans at your own usage.
I'm moving to Josephine. How do I set up electricity?
Confirm the address is on Oncor's wires, then pick a plan and a start date. In 75173, 13.2% of residents moved in the past year (ACS); 3 meters in 75173 went vacant-to-active Oct. 7-18, 2026.
Why does my Josephine home have a Nevada address?
75173 covers part of Josephine, but the Postal Service names most of it Nevada: that postal city is on 78 percent of the ZIP's 2,422 competitive home meters, Josephine on 22 percent. Your mailing city is not your city limits; the service address decides the utility.
