Weather and electricity in Lancaster
Typical weather near Lancaster, from the nearest NOAA station with a complete 1991-2020 record: Ferris, about 8 miles from the city center (station elevation 470 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 97°F; January has the coolest average low, 36°F. Average daily highs reach 90°F or more in June to September. 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 617 for the month, and heating-degree days (below 65°F) peak in January at 575. 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 Dallas County
The Texas Railroad Commission's county table lists a record low of -10°F (1899) and a record high of 115°F (1909), and a regional estimate of 30 consecutive hours as a typical longest freezing or frozen-precipitation period for Dallas County. These are historical county extremes, not Lancaster'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 Lancaster, and not an estimate for your home. EIA source.
