Our Story

Founded in 1994 by Al Powers, installing and servicing generators has been our sole business for 20 years. We have grown from a one-person operation to employing over 37 valuable staff members and technicians who align together on our values of integrity, service and communication. We keep our word to our customers in providing these things. We do the job right the first time, with the least amount of disruption for your family. You won’t have a mess to clean up when we are done. Problems rarely occur, but when they do, we work to resolve them quickly.

Our A+ standing with the Better Business Bureau is evidence of our top-quality customer service. Our electricians are licensed in all the New England states and we proudly employ EGSA Certified service technicians; this certification is earned only by a few generator technicians in the Northeast. Our factory-trained staff is continually expanding their generator knowledge to ensure we are up to date on the latest and greatest within the generator industry.
