Hurricane & Storm Season Generator Prep: What to Do Before the Power Goes Out

If you already have a standby generator

Test it before storm season starts, not during a hurricane watch. A generator that hasn't run in months can fail on the one day you need it.

• Run it under load for at least 20–30 minutes, not just an idle self-test
• Check the automatic transfer switch cycles correctly and doesn't backfeed the utility line
• Top off fuel (propane tank level, or fresh stabilized gasoline — old gas is a leading cause of no-starts)
• Replace the battery if it's more than 2–3 years old; a dead starter battery is the #1 reason standby units fail to start
• Clear brush, debris, and flood risk from around the unit's enclosure
• Confirm your maintenance contract or warranty is current if you have one

If you're relying on a portable generator

Portable generators are fine for essentials, but they kill people every year through carbon monoxide poisoning and electrocution from improper hookups. Two rules matter more than anything else:

• Never run it inside a garage, porch, or anywhere near windows and doors — CO can build up even with the garage door open
• Never plug it directly into a wall outlet without a transfer switch or interlock — that back-feeds the grid and can kill a utility lineworker restoring power on your street

If you don't have a generator and storm season is close

A licensed electrician can install a manual transfer switch or interlock kit in a single visit in many cases — that alone lets you safely run a portable generator into your panel instead of running extension cords through a window. It's a fraction of the cost and lead time of a full standby system.

For a whole-home standby unit, the honest timeline is: sizing and quote (same week), permit application (varies heavily by jurisdiction), equipment lead time (can be weeks depending on model availability), then install and inspection. If a storm is already forming, you're planning for next season, not this one — a portable unit with a proper transfer switch is the realistic near-term option.

Panel load: the step people skip

Before sizing any generator, an electrician should walk through what actually needs to run during an outage — refrigerator, sump pump, well pump, medical equipment, HVAC — versus what doesn't. Undersizing a generator for real-world load is the most common reason people are unhappy with a new install. This is also a good moment to check whether your panel itself needs an upgrade; older 100A services sometimes can't support a standby unit without additional work.

A pre-storm checklist worth keeping

1. Test standby unit under load, or confirm portable unit starts and runs clean
2. Check transfer switch / interlock operation
3. Fresh fuel or full propane tank; fresh battery
4. Know which circuits are on backup power and which aren't
5. Have a licensed electrician's number saved before you need one — not during the storm

Final thoughts

Generator readiness is mostly maintenance, not equipment. Most storm-season failures come from stale fuel, dead batteries, and units that were never tested under real load — not from the generator itself being inadequate. If you're starting from zero this close to a storm, focus on a safe manual transfer setup now and plan the full standby install for the off-season.
