Learn About Backup Power
Everything you need to safely use a generator — from choosing the right type to avoiding CO poisoning.
Types of Portable Generators
Fossil fuel generators run on gasoline or propane, affordable but noisy. Solar-battery generators are silent, plug-and-play, maintenance free and emission free, but have limited output. PGnE uses a fleet of small/mid size gas/propane/battery generators (1500-3500 watts) to accommodate different needs.
Carbon Monoxide Safety
NEVER run a gas/propane generator indoors, in a garage, or near windows. CO is colorless and odorless and kills within minutes. Over 400 Americans die each year from generator-related CO poisoning. Always operate at least 20 feet from any opening in your home. Install a CO detector on every floor of your home before an outage season.
✅ Completely SAFE to run a battery generator indoors!
What Can a Generator Power?
In an emergency, a small 1500-2000 watts generator can easily run a refrigerator, small microwave, a few lights, phone chargers, and a medical device like a CPAP or oxygen concentrator simultaneously. It cannot run central A/C or an electric stove.
Fuel Storage
Propane is much easier to deal with than gasoline. PGnE dual-fuel generators prefer propane. For gasoline, always store in approved red containers, away from heat sources, in a detached garage or shed. Never store fuel indoors. Add fuel stabilizer if it will sit more than 30 days.
Electrical Safety
Never plug a generator directly into a wall outlet (back-feeding). Use a licensed electrician to install an interlock kit or transfer switch if you want to power your whole house.
Preparing Your Home
Make a list of your essential electrical needs before an outage. Know where your main breaker is. Have a printed copy of this guide — don't rely solely on your phone. Sign up for county emergency alerts at scc.alertscc.com.
