Protect your business with a standby generator

After the horrendous storms of the last few years, many businesses are asking John Duffy Energy Services to install backup generators. These units start up almost immediately after you lose power, allowing your business to continue operating seamlessly.

Available in a range of kilowatt output capacities, our natural gas generators from leading manufacturers like Generac and Kohler feature an automatic transfer switch that starts the generator when a power outage occurs, regardless of whether you are at your property or away!
