Fuel savings GE’s J920 FleXtra generator set offers a top-of-its-class electrical efficiency of 49.1 percent for 50 Hz and 49.9 percent for 60 Hz. That adds up to big fuel savings throughout the lifetime of any plant. Over the course of 15 years, for example, an Asian facility could realize fuel savings of as much as $ 40 million for a 100 MW power plant.

CHP advantage with J920 FleXtra Thanks to 2-stage turbocharging the J920 is a very good solution for combined heat and power applications. It provides about 4 % pts higher total efficiency, because about 800 kW of additional heat can be utilized from the J920 GenSet compared to an equivalent single stage turbocharging engine. Over the course of 15 years, for example, a facility could realize additional revenues from winter heat sales of more than $ 14 million from a 100 MW CHP power plant.

Power plant solutions GE’s J920 FleXtra gas engine can be deployed in large gas engine power plants, offering a standardized powerhouse plant concept with fast delivery times and lower installation costs. While the size of the facility, actual plant design and layout are site specific, the J920 FleXtra solution has been developed as a modular system with a small footprint. This permits seamless installation for any multiple- engine configuration with flexible size options at top-of-class efficiency levels. When this multiple-engine concept is combined with a five-minute engine startup time, the result is outstanding flexibility for baseload, cyclic and peaking operation.
