Backup power without a generator: what Houston homeowners should know

Quiet home-battery backup when CenterPoint goes dark — no fuel, no fumes, $0 upfront.

  • $0 upfront
  • Monitored, maintained & insured
  • Backup during outages

The short answer

By the VPP Home Energy team · Last updated July 10, 2026

For most Houston homes, backup power without a generator means a home battery. Qualified homes served by CenterPoint Energy — Houston’s deregulated utility — can get home battery storage through a $0-upfront program, with the equipment installed, monitored, maintained, and insured by the provider. No engine, no fuel, no exhaust.

The question got urgent after Hurricane Beryl. On July 8, 2024, Beryl knocked out power to somewhere between 2.2 and 2.7 million CenterPoint customers, and some Houston-area homes waited more than 12 days for the lights to come back — in heat that topped 100°F. In the weeks that followed, hundreds of Texans ended up in emergency rooms with carbon-monoxide poisoning tied to portable generators. This page lays out what happened, why safety officials keep warning about the standard backup plan, and the quieter path Houston homeowners are turning to instead — including how to find out if your home qualifies.

Key takeaways

  • Beryl was a grid-scale failure

    2.2–2.7 million CenterPoint customers lost power; some homes went 12+ days in 100°F+ heat (CNN; Houston Public Media, 2024).

  • Generators carried a documented cost

    Roughly 400 Texans were treated in ERs for generator-related carbon-monoxide poisoning after Beryl (Texas Tribune, 2024).

  • A battery backs up without burning

    No engine, no gasoline, no exhaust — essentials like lights, the fridge, and Wi-Fi can stay on through an outage.

  • Qualified homes pay $0 upfront

    Eligibility starts with your utility — most Houston homes are on CenterPoint, which may be a fit. A quick check tells you.

What happened

What happened to Houston’s power when Beryl hit?

Hurricane Beryl came ashore on July 8, 2024, and took down power for somewhere between 2.2 and 2.7 million CenterPoint customers across the Houston area (CNN, July 9, 2024). That is not a neighborhood outage — that is most of a major American metro losing electricity in the same week.

The restoration was the harder part. Some homes waited more than 12 days for power to come back, through Houston heat that topped 100°F (Houston Public Media, Aug 27, 2024). And Beryl was not a freak event so much as the sharpest recent example of a pattern: federal data shows Texas led the nation in major power outages from 2019 to 2023 — 263 events, averaging about 160 minutes and roughly 172,000 customers each (DOE data via Governing.com, Mar 13, 2024). Winter cuts the other way, too: Winter Storm Uri in 2021 left more than 4.5 million Texas homes dark (Texas Tribune). The strain isn’t easing — ERCOT’s own forecast calls for a record 92.2 GW summer peak in 2026, above the 85.5 GW all-time record (Texas Tribune, Jan 29, 2026; ERCOT seasonal update). It is July again. Hurricane season is not a hypothetical in Houston; it is the calendar.

The safety story

Why are safety officials warning about portable generators?

After Beryl, the emergency-room data told a second story. Roughly 400 Texans were treated for carbon-monoxide poisoning tied to portable generators in the weeks after the storm, and Harris County recorded at least two deaths from it (Texas Tribune, Aug 5, 2024).

Carbon monoxide is the exhaust of burning fuel, and you cannot see it or smell it. The people it hurt after Beryl were, overwhelmingly, just trying to keep a fridge cold, a fan moving, and a household comfortable through brutal heat. That deserves respect, not a scare headline. It also deserves a practical note: if you do run a portable generator, run it outdoors only, far from doors, windows, and vents — never in a garage, even with the door open.

But the larger lesson Houston took from Beryl is simpler: the standard backup plan asks a lot of a household at the worst possible moment — fuel to store, an engine to place and start, exhaust to manage — and it carries a real, documented risk. A backup source that doesn’t burn anything removes that risk entirely. That is the switch this page is about.

The generator alternative

How does a home battery replace a generator?

A home battery stores energy and hands it back the moment the grid drops. Nothing combusts, so there is no exhaust and no carbon monoxide to manage — and no fuel cans, no engine noise, and nothing to wheel out and set up in a storm’s aftermath.

Home battery

Backup that lives on your wall:

  • No engine, no gasoline, no exhaust fumes
  • Quiet — no motor running through the night
  • Nothing to set up or refuel mid-crisis
  • Monitored, maintained & insured by the provider
  • $0 upfront for qualified homes

Portable generator

The standard plan, and its trade-offs:

  • Gasoline to buy, store, and refill
  • Exhaust contains carbon monoxide — outdoor-only operation
  • Engine noise for as long as it runs
  • Manual setup in the middle of the aftermath
  • You own the upkeep and the repairs

What stays on is the honest question. Home battery storage sized for your home can keep essentials running — lights, the fridge, Wi-Fi — through an outage. A specialist sizes the conversation to your actual home: what you’d keep powered, for how long, and what the program looks like in writing before you decide anything.

Eligibility

Which Houston homes qualify for the $0-upfront program?

Eligibility starts with who delivers your electricity. Most Houston-area homes have their power delivered over CenterPoint Energy’s wires — no matter which retail provider sends the bill — and CenterPoint is a deregulated Texas utility, so those homes may be a fit.

Homes in an electric cooperative or most municipal utilities are outside the competitive market and don’t qualify. Not sure which one your home is on? You don’t need to be — the quick check below sorts it out, and a specialist confirms your home’s exact fit.

What happens during a long outage like Beryl?

How long a battery carries your home depends on the system and on what you keep running — a home powering only essentials lasts far longer than one running everything at once. The provider monitors the system, and your specialist explains how the program handles extended outages for your specific home before you decide.

How do I know if my Houston home qualifies?

Eligibility starts with your utility. Most Houston-area homes have their power delivered by CenterPoint Energy, a deregulated Texas utility — those homes may be a fit. Homes in an electric cooperative or most municipal utilities are not part of the competitive market. Take the quick eligibility check and a specialist confirms your home’s fit.
