Inspired by the future

2G is committed to being a driving force behind the expansion of decentralized cogeneration across the globe by being a pioneer and innovator and thus laying the groundwork for a successful energy transition.

2G Energy AG

Founded in Heek (North Rhine-Westphalia, Germany) in 1995, the publicly traded 2G Energy AG is currently one of the leading international manufacturers of combined heat and power systems for the decentralized production of energy in the output range from 20 to 4,500 kW. As a technological leader with 14 subsidiaries and over 900 employees worldwide, we provide holistic energy supply solutions suited to almost any field of application imaginable, including the agricultural sector, municipalities, the housing industry, commercial enterprises, medium-scale and major industrial enterprises, the energy sector and many more.


We think of ourselves as a system partner. This means that 2G is a single-source provider of all planning, implementation and maintenance services which ensures the lasting, economically efficient operation of the system. More than 8,500 customers worldwide already rely on our highly efficient and ecologically sustainable technologies.

Combined heat and power generation

The backbone of energy transition

Climate change is the biggest challenge of our time. A concerted effort across the borders of states and continents is required to stop it. The global energy transition is probably the most significant milestone on this way. We can only succeed in mastering it if the supply is secured at all times - and that is exactly what cogeneration can guarantee. Therefore, cogeneration is nothing less than the backbone of the energy transition.

Why 2G?

Research and Development

Because we develop cutting-edge technology

As technological trailblazer, 2G actively shapes the creation of a climate-neutral future through its innovative technology. Our considerable research and development department is dedicated to the continuous improvement of our gas engine concepts which already allow us to reach overall efficiencies from 85 to far over 90 per-cent in the output range between 20 and 550 kW.


Because cutting-edge technology alone is not enough

Our objective is to let our customers focus on their core business activities while their CHP is running reliably and to their economical benefit. For this reason, 2G does not simply provide you with a combined heat and power system but also with world class service: Our extensive network of adaptable service technicians is perfectly trained, equipped and always quickly by your side. Digital service solutions, such as the self-developed malfunction prediction I.R.I.S., efficiently prevent unplanned downtime.


Because the energy transition should not be decided by money

To lastingly promote the expansion of decentralized cogeneration, we offer customized rental and leasing concepts in all performance categories so you can establish and improve your own supply concepts and contracting solutions. This way, you can benefit of state-of-the-art energy technology without having to tie up capital.
