Murphy, Texas electricity: only part of town can choose a provider
Part of Murphy is on the competitive market and part isn't, so the first question for any Murphy 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 2,157 active residential meters with a Murphy address, all on Oncor's wires (October 5, 2026). Only part of Murphy is on the competitive market; the Census counts about 6,015 households in the city. Many of the rest likely get power from an electric co-op or another utility without retail choice, so check your exact address.

Weather and electricity in Murphy
Typical weather near Murphy, from the nearest NOAA station with a complete 1991-2020 record: Lavon Dam, about 7 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.

Historical weather records for Collin County
The Texas Railroad Commission's county table lists a record low of -11°F (1899) and a record high of 115°F (1901), and a regional estimate of 30 consecutive hours as a typical longest freezing or frozen-precipitation period for Collin County. These are historical county extremes, not Murphy's monthly averages and not a forecast; the normals above describe ordinary months.
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 Murphy, and not an estimate for your home. EIA source.
