Natural gas generators from Generac Industrial are becoming the preferred solution for many applications as they provide longer runtimes, have easier permitting and units with natural gas have 90% fewer emissions compared to diesel generators. In addition, there is much less 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 gaseous generators rely on a reliable underground pipeline network that is not impacted by weather. Generac has proven itself to be the expert in natural gas generators, and has earned two Frost and Sullivan Awards and a recent CSE award for their 500 kW generators. Visit this page for a full product listing of Generac Industrial gaseous generators. -
