The best backup power option for Long Island outages depends on how long and how often your power goes out. For long, frequent storm outages, a natural-gas or propane standby generator with an automatic transfer switch is the most reliable — it runs essential or whole-home loads for days. For quiet, instant backup and pairing with solar, a home battery like the Tesla Powerwall is ideal for shorter outages. On a budget, a portable generator wired through a proper manual transfer switch safely powers essentials. The one option to never use is backfeeding a portable generator through an outlet — it's illegal and deadly. We help match the right system to your home.
Why it matters for Long Island homeowners
Long Island's exposure to nor'easters and hurricanes means outages are a question of when, not if. The right backup keeps your heat, refrigerator, sump pump, and medical equipment running. The wrong choice — or an unsafe DIY hookup — risks your home and your family. Matching the system to your real outage history is what we do first.
Your options, ranked by outage type
Long, frequent outages: standby generator with automatic transfer switch. Short, occasional outages or solar homes: home battery. Budget-conscious essentials-only: portable generator with a properly installed manual transfer switch. Whole-home resilience: a battery plus generator combination.
Common Mistakes to Avoid
- Backfeeding a portable generator through a dryer or range outlet — illegal and life-threatening.
- Undersizing the system for the loads you actually need to keep running.
- Skipping the transfer switch and risking lineworker safety and your equipment.
When to Call a Professional
Any transfer switch or standby system must be installed by a licensed electrician. Never connect a generator to your home without a proper transfer switch.
Frequently Asked Questions

A standby generator with automatic transfer switch is best for long, frequent outages; a home battery is best for quiet, short-outage backup and solar pairing. Many homeowners combine both.
Can I use a portable generator safely?
Yes, when wired through a properly installed manual transfer switch. Never backfeed through a wall outlet — it endangers your home and utility workers.
