May 1, 2010 | By Anthony Capkun

Caterpillar announced the availability of the XQ1250G natural gas mobile generator set. Sold and rented exclusively through Cat dealers, it is rated for continuous operation at 1250kW 480/277V 60Hz. It promises an easy-to-use control system to parallel with other Cat generators or with an electric utility. The XQ1250G power module employs a low emission G3516B engine with integrated exhaust after-treatment. It operates on low-pressure natural gas and is equipped with an active air-to-fuel ratio controller to allow for varying fuel energy content. The G3516B engine, fuel regulation components, control and distribution system, and cooling package are housed in a sound-attenuated 40 ft ISO container. The design of the XQ1250G includes 100% spill containment of all engine fluids.
