What is a Gas generator?

A gas generator is a power-generating device that uses combustible gases such as natural gas, propane, or biogas as fuel to drive an engine, which in turn powers an electric generator. Like diesel generators, gas generators are commonly used for emergency backup power, on-site power generation, and peak-shaving applications. One of their main advantages is cleaner combustion, producing fewer harmful emissions and being more environmentally friendly. Gas generators operate by using a gas engine to rotate an alternator. They are typically quieter and produce less odor than diesel models, making them well-suited for use in urban areas or indoor facilities. When integrated into a cogeneration (combined heat and power) system, the waste heat produced during power generation can be reused for heating water or space heating, increasing overall energy efficiency.

Since they can utilize city gas or liquefied petroleum gas (LPG), fuel supply is relatively easy and suitable for long-term storage. Gas generators are often adopted by hospitals, data centers, and public institutions to ensure stable power during emergencies or power outages. By offering both environmental benefits and energy reliability, gas generators represent a key solution for achieving a sustainable and resilient energy infrastructure.
