## Questions
**Can Highland Park residents pick their own electric company?** Yes, where Oncor's wires reach the house, which in Highland Park is most of the city: 3,453 homes with a Highland Park mailing address were on the competitive market on October 5, 2026, 1.05 for each Census household. No Highland Park ZIP code carries a split flag, but only an address lookup is certain.
**Where do most Highland Park electricity customers live?** 75205. It holds 2,710 Highland Park-addressed competitive homes; counting every address in the ZIP, ERCOT has 11,062 meters for roughly 9,655 households, a 1.15 ratio.
**Are electric bills high in Highland Park?** Depends on the part of town. The ACS 2020-2024 found 39.0 percent of 75205 households paying over $250 a month for electricity and 11.1 percent in 75219. Home size, age and electric heating drive most of that gap, so compare plans at your own usage.
**How do I start electric service at a new Highland Park address?** Start with the address check: Oncor-delivered Highland Park homes choose among the plans offered there and set a start date. Turnover is real in 75219, where 28.7% moved in the past year (ACS); ERCOT logged 18 vacant-to-active meters in 75219 Oct. 7-18, 2026.
**Why does my Highland Park home have a Dallas address?** 75205 covers part of Highland Park, but the Postal Service names most of it Dallas: that postal city is on 40 percent of the ZIP's 11,062 competitive home meters, Highland Park on 24 percent. Your mailing city is not your city limits; the service address decides the utility.
**Who do I call in Highland Park when the power goes out?** Oncor, at oncor.com/outages: it carries power to all 3,453 Highland Park-addressed competitive homes, whatever retail provider bills them.
