Gas piston (gas-to-power) generators are units that convert gas combustion energy into electricity using a piston engine. They typically run on natural gas, liquefied gas, or biogas. The core component is an internal combustion engine that drives a generator to produce electrical power. These systems are widely used in industry, utilities, and private facilities, especially where reliable backup or autonomous power supply is required.

One key advantage of gas piston generators is their high efficiency and environmental friendliness compared to diesel alternatives. They offer stable operation with low noise levels and reduced emissions, and can be integrated into cogeneration systems that produce both heat and electricity. These features make gas piston generators increasingly popular as the focus on energy efficiency and environmental sustainability grows.
