What to plan for in Houston

  • Tornadoes (very high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
  • Hurricanes (very high): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.
  • River and heavy-rain flooding (very high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.

Choosing an installer

  • License: check the contractor on the TDLR license search and that the license covers this work.
  • Quote: ask for an itemized written quote that names the equipment, warranties and who pulls the permit and handles the utility approval.
  • Compare: get two or three quotes and compare them line by line, not only the total.

Backup Generator Installation in Houston FAQs

What size generator do I need?

It depends on whether you run central air conditioning or only essentials. Use the generator sizing calculator, then have a licensed electrician confirm.

Natural gas or propane?

Natural gas needs a gas line at the home; propane needs a tank, which may need its own permit. Ask your installer and the permit office.

Do I need a permit for a standby generator in Houston?

Usually yes, and the utility may need to approve solar and batteries. Houston Permitting Center (Houston Public Works) handles permits in Houston; see the permit information above.
