About Greenwich Power Systems

Greenwich Power Systems has earned the trust of its customers as being their go to reliable generator company throughout Fairfield County, Connecticut, and Westchester County, New York. Greenwich Power Systems holds a PowerPro Elite Dealer status, which means we’ve met standards set by Generac Power Systems and KOHLER Generators. Earning this designation was not easy, but we are proud of it. Our customers consider us their preferred company for standby generators.

We sell, install and service standby home generators. We also install, sell and service generators for small businesses and larger commercial and industrial sites.

There are hundreds of dealers of standby and portable generators within 25 miles of our home territory, which is just one reason why we take the time to understand your needs at our first meeting. Our factory-trained technicians and knowledgeable consultants will provide you with all the information you need to make the best decision possible for your home, business or commercial property.

Greenwich Power Systems is a division of Greenwich Construction, a leading homebuilder in Lower Fairfield County. Many of our customers put their trust in us to build their homes, and many will say we’ve exceeded their expectations. It’s the same level of service and dedication that carries over into our power solutions business. If we weren’t lucky enough to build your home, then give us a shot at making sure you’re never left in the dark.
