## Questions
**Can I choose my electricity provider in Santa Fe?** Yes, where CenterPoint's wires reach the house, which in Santa Fe is most of the city: 9,111 homes with a Santa Fe mailing address were on the competitive market on October 5, 2026, 1.94 for each Census household. Addresses in 77510, 77511 (all split) need an exact-address check before you shop.
**Which Santa Fe ZIP code has the most homes on the competitive market?** That is 77510, home to 6,412 of the competitive meters with a Santa Fe address. ZIP-wide: 6,643 ERCOT meters, about 5,441 Census households, 1.22 per household.
**How many Santa Fe households have a $250 electric bill?** Depends on the part of town. The ACS 2020-2024 found 52.9 percent of 77517 households paying over $250 a month for electricity and 52.4 percent in 77510. 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 Santa Fe address?** Start with the address check: CenterPoint-delivered Santa Fe homes choose among the plans offered there and set a start date. Turnover is real in 77510, where 10.8% moved in the past year (ACS); ERCOT logged 7 vacant-to-active meters in 77510 Oct. 7-18, 2026.
**Why are there more electric meters than households in Santa Fe?** 9,111 Santa Fe-addressed meters against 4,693 city households is 1.94 per household: the Santa Fe postal area extends past city limits, and new homes get meters before the Census counts them. It doesn't mean every nearby address can choose.
**Who do I call in Santa Fe when the power goes out?** Call CenterPoint (centerpointenergy.com/outage), the wires utility for Santa Fe's 9,111 competitive homes; a retail provider can't fix lines.
