Permanently installed generators are set up outside the home or business and connected to natural gas or propane fuel so they are ready to provide electricity if a power outage occurs.

These units come in lockable, weather-protected enclosures and are designed to be in service for many years. An automatic transfer switch (ATS) starts and transfers your energy usage to the generator within seconds when utility-fed power is unavailable. When the utility-fed power returns, the ATS switches you back to the utility and automatically shuts down the generator, whether you are at home or away. These generators even test themselves weekly to ensure they’re ready 24/7.

Portable generators are available from many retailers within PSE’s service area. Most are designed to be manually started and connected directly to individual electrical devices or connected to the home via a correctly and legally installed manual transfer switch. Most types are fueled by gasoline. Unlike permanently installed generators, portable generators will not operate without someone who will start, connect and constantly monitor their operation.

Battery energy storage systems are another option to provide temporary back-up power during an outage and store excess electricity from rooftop solar. If you’re purchasing your own standalone battery, PSE offers installation guidelines.
