CPS Energy San Antonio Setup for New Residents (2026)

San Antonio newcomers from Houston or DFW often open Power to Choose first — then discover their apartment is in CPS Energy territory, where retail electric shopping does not apply. Inside the city utility footprint, you sign up with one municipal provider for power (and often gas), not a dozen competing REPs.

Open your CPS account at least a few business days before move-in. Vacant units frequently have disconnected meters until a new customer signs up — showing up Saturday to a dark, hot apartment is a rough welcome to South Texas summers.

Municipal utility, not ERCOT shopping

CPS Energy is a city-owned utility serving San Antonio and parts of the surrounding area — structurally similar to Austin Energy rather than the deregulated Houston model.

Area type	Electricity setup
San Antonio city addresses (most)	CPS Energy — direct account
Many northern Bexar County suburbs	May fall under ERCOT retail choice — verify address
New Braunfels, Schertz, some corridors	Often not CPS — check before move-in

Search your exact address on CPS Energy’s site. A cousin’s experience in Katy or Plano does not transfer here.

Start service before move-in day

1. Confirm the unit is not master-metered — some older complexes bill electricity through the landlord
2. Create a CPS account online or by phone with your service start date matching lease start
3. Provide ID and Social Security number for credit screening
4. Pay a deposit if required — amount varies by credit history; budget roughly $100–$250 as a planning range (rates change)
5. Save your account number for move-in photos and DPS paperwork

Schedule activation at least a few business days before movers arrive. Vacant units frequently have disconnected meters until a new customer signs up.

A common snag: assuming the prior tenant’s account covers your move-in weekend. CPS bills the person whose name is on the account — if that is not you, you may arrive to a dark, hot unit in June.

New customers without Texas utility history often pay a deposit held until twelve months of on-time payments — or longer if bills slip. Ask about deposit waiver programs if you had active accounts elsewhere; policies change, so confirm at signup rather than budgeting zero.

If your building uses all-electric appliances (common in newer San Antonio apartments), you may skip a separate gas signup entirely. Older homes near Monte Vista or King William sometimes need gas relight appointments when service was fully shut off — schedule that when you call, not after you smell a pilot issue.

Electric, gas, and summer bills

CPS provides electric service across its territory and natural gas in much of San Antonio. Combined billing simplifies autopay for renters used to separate gas companies in North Texas.

San Antonio summers push AC hard — expect higher kWh usage June through September than spring or fall. Budget billing or average payment plans may be available after you establish usage history; ask when you open the account.

Your CPS bill doubles as Texas DPS residency proof when it shows your legal name at the service address. Forwarded PDFs from an old state or bills in a roommate’s name usually fail the window clerk’s checklist.

People often ask: why their first CPS bill looks high. Partial months, deposit installments, and June heat stack quickly. A two-bedroom that ran $80 in April can cross $160 in August when highs sit near triple digits.

Suburbs and address surprises

Live in Stone Oak, Alamo Ranch, or near the county line? Your lease might sit inside CPS territory — or just outside in an ERCOT area served by retail providers and a different wires company. The general Texas utilities guide covers REP shopping when CPS does not serve your meter.

Apartment hunters signing in downtown or Medical Center neighborhoods are almost always CPS. Verify before you sign a twelve-month retail electric contract that cannot attach to your ESIID.

Worth knowing: “I work in San Antonio but live in Boerne — CPS or not?” Hill Country addresses outside the city limits frequently land in Pedernales Electric Cooperative or retail-choice zones. Run the address lookup before you sign the lease, not after the truck is loaded.

Water, trash, and what CPS does not cover

CPS handles electric and gas — not your water bill. San Antonio Water System (SAWS) bills most city renters separately. Open SAWS in the same week as CPS so move-in does not leave you without running water for dish cleanup.

Trash pickup routes through the City of San Antonio solid waste program in many neighborhoods; some HOAs and apartment complexes bundle it into rent. Your leasing agent should say who to call when the blue bin goes missing — that is not a CPS ticket.

Internet installs stretch 1–2 weeks in new construction — book fiber or cable when you sign CPS, not on move-in morning.

Tie to DPS and move-in timing

Book your San Antonio DPS appointment after you have lease plus CPS bill in your name — two residency documents sorted. Match unit numbers exactly between lease and utility account (“Apt 512” vs “Unit 512”).

Coordinate CPS start date with move-in inspection timing so you can test AC, stove, and hot water on day one. Bexar County registration runs on a ~30-day clock if you own a vehicle — separate from your 90-day license deadline at DPS.
