Standby Generators

With an automatic standby generator from Colonial Electric Service, you will never have to worry about power outages again. These generators automatically sense a utility failure and restore electricity to your home or business instantly—even when you’re not there! Your business continues to provide essential services and your family is safe and secure.

We provide:

Commercial Standby Power - Losing power for even a few hours can mean thousands of dollars in lost revenue to your business. Security systems go down, refrigerated goods spoil, and customers are turned away. A commercial generator is powerful enough to back up your entire business without the cost of expensive configured systems. Keep your business open with a competitive advantage.

Residential Standby Power - Power is a necessity for heating, cooling, refrigeration, and lights. Power outages are occurring more frequently than ever and lasting longer with devastating effects. Stand up to unpredictable weather and unforeseen outages with the most trusted name in residential standby power. If the power ever goes out, your standby generator goes on—automatically—protecting you and your home 24/7.

We also provide emergency power systems where you can use your portable generator and have a system that is installed to properly disconnect the utility power to your own generator.
