Jenbacher gas engines — now branded as INNIO Jenbacher — represent the premium tier of industrial gas engine technology for cogeneration (CHP), biogas, landfill gas, and natural gas power generation applications. GE Jenbacher, as it was known for many years, established a global reputation for fuel flexibility and high electrical efficiency in the 250kW to 4.5MW range. Power Generation Enterprises carries Jenbacher generator sets for industrial, agricultural, and specialty gas applications.
Jenbacher engines stand apart from conventional natural gas generator platforms in their ability to run on very low-BTU gases — sewage treatment biogas, agricultural waste digester gas, landfill gas, and industrial process gases — with high efficiency and low emissions. This makes them the preferred choice for wastewater treatment plants, food processing facilities, and landfill energy recovery projects.

Jenbacher Werke was founded in 1959 in Jenbach, Austria as an industrial manufacturing company. The gas engine division, established in the 1960s, grew to become the company's primary business by the 1990s. GE (General Electric) acquired Jenbacher in 2003, bringing the brand into GE's global power generation portfolio and significantly expanding its market reach. In 2018, GE divested its distributed power business to Advent International, creating INNIO — the independent company that now owns and develops both the Jenbacher and Waukesha gas engine brands. INNIO continues to manufacture Jenbacher engines in Jenbach, Austria and supports the installed global fleet with factory parts and engineering services.
Jenbacher gas engines achieve 40-44% electrical efficiency — the highest of any widely available generator engine platform — reducing fuel cost per kWh in CHP and prime power applications.
Jenbacher systems are purpose-designed for combined heat and power — with factory-integrated heat recovery achieving combined efficiencies of 80-90% from the same fuel input.
Jenbacher engines are engineered to handle variable-composition biogas from agricultural digesters, landfill operations, and wastewater treatment plants that would damage conventional gas engines.
Jenbacher covers 250kW (J208) through 3,500kW+ (J612) in a consistent engine architecture, enabling projects from small biogas installations to large-scale utility CHP plants.
Manufactured in Jenbach, Austria under INNIO ownership — Jenbacher engines are built to the stringent quality standards required by European industrial and utility operators.
Jenbacher engines are designed for continuous-duty CHP operation with TBO of 30,000-60,000 hours — many first-generation units from the 1990s are still operating after 25+ years.

Jenbacher gas engines are primarily used for combined heat and power (CHP/cogeneration), biogas power generation (from landfill gas, wastewater treatment digester gas, or agricultural waste digesters), and natural gas prime power applications requiring high electrical efficiency. Their 40-44% electrical efficiency is among the highest of any gas engine platform.
Yes. Jenbacher was marketed as GE Jenbacher from 2003 to 2018 while part of General Electric. In 2018, GE divested its distributed power business to create INNIO — the independent company that now owns the Jenbacher brand. Engines are still manufactured in Jenbach, Austria with full factory support under INNIO ownership.
Jenbacher offers higher electrical efficiency (40-44% vs CAT G3500's 35-38%) and superior low-BTU gas flexibility. Caterpillar has a much larger North American dealer network. Jenbacher is preferred for CHP and biogas energy recovery; CAT G-series is preferred for conventional natural gas standby with strong local service support.
Yes — this is Jenbacher's primary design advantage. Jenbacher engines are engineered to handle variable-composition biogas from agricultural digesters, landfill gas, and sewage treatment plants. The engine management system automatically adjusts ignition timing and fuel-air mixture to accommodate gas composition variations.
CHP (Combined Heat and Power), also called cogeneration, simultaneously generates electricity and useful heat from the same fuel source — achieving combined efficiencies of 80-90% vs 35-45% for electricity-only generation. Jenbacher systems are specifically engineered for CHP with factory-integrated heat recovery systems, making them ideal for hospitals, district heating, and industrial processes.
Jenbacher is owned by INNIO, formed in 2018 when GE divested its distributed power business. INNIO also owns the Waukesha gas engine brand. Engines are still manufactured in Jenbach, Austria with full factory parts supply and engineering services.
The Jenbacher J612 is a large-frame gas engine producing 2,000-3,500kW in generator set configuration depending on fuel type and application. It is the largest engine in the Jenbacher lineup, used for large-scale CHP plants, industrial energy recovery, and landfill gas power stations.
Jenbacher engines are designed for continuous-duty CHP operation with TBO of 30,000-60,000 hours depending on engine series and fuel quality. Many first-generation Jenbacher installations from the 1990s are still operating after 25+ years. Factory-trained service and a robust global parts network support long-term operation.
Yes to both. Power Generation Enterprises can source and ship Jenbacher generator sets for CHP, biogas, and natural gas applications. Financing is available for qualified buyers. Contact us at (818) 484-8550 for current availability and project-specific requirements.
