Longer Runtimes and “Green” Fuel: Natural Gas Generators

Natural gas is becoming the preferred solution in many applications as it provides much longer runtimes, the permitting is easier, and they have 90% fewer emissions compared to diesel generators. In addition, there is virtually no maintenance associated with natural gas generators, while diesel fuel requires conditioning annually.

Another advantage is that more AHJ’s are recognizing natural gas generators for sole off-site fuel choices because these generators rely on a strong underground pipeline network that is rarely impacted by weather. 

And Generac is the expert in natural gas generators: with two Frost and Sullivan Awards and a recent CSE award for our 500 kW generators. Tested, trusted, and a bit disruptive: natural gas generators.
