g-box. Your profitable small power plant by 2G. Highly efficient. Quickly pays for itself. 2G. Cogeneration.

Global success with cogeneration. A small power plant which produces power and heat locally is the ideal solution for anyone wanting to reduce energy costs in the long term and wishing to protect themselves against further increases in the price of electricity. As a pioneer, innovator and one of the world‘s leading manufacturers of distributed power generation systems using cogeneration, also referred to as combined head and power (CHP), we have commissioned thousands of technologically advanced, highly efficient CHP plants since 1995. Satisfied customers in more than 35 countries confirm...

Power generation in transition. Power generation in Germany is changing rapidly and we are facing huge challenges. In the energy mix with renewables, such as solar and wind power, highly efficient cogeneration makes an important contribution to a stable energy supply. The share of CHP electricity is expected to rise significantly in the coming years.

c Reliable. With the g-box by 2G, you get a highly efficient small power plant which reliably supplies power and heat, regardless of the time of day or the weather. It is manufactured in Germany to high quality standards in accordance with DIN EN ISO 9001. & Independent. Heating and electricity costs have risen constantly over the past 10 years. Investing in a small power plant like the g-box is a quick, financially sound way of protecting yourself against this development. Why? Because you become your own energy supplier. You feed the electricity that you don't use yourself into the public...

Power from your own production. The combined generation of mechanical energy (power) and useful heat is described as cogeneration. While the mechanical energy is converted directly into electricity by a generator, the waste heat arising during power generation can be used locally to heat buildings, for heating water or as process heat in industry for example. The g-box. Perfect for residential buildings.

Energy efficiency comparison. Power in large power plants *Even higher efficiency levels can be achieved with condensing technologies. The heat produced during cogeneration is stored and can be used at any time for space heating or water heating regardless of the production of electricity. This means you don’t have to heat every time you generate electricity, or generate electricity if you want to heat. What’s more, even if you’ve only just invested in a new heating system, it will pay to think about a g-box! Power and heat whenever you wa

Wind turbines Photovoltaic plants Virtual power plants CHP plants Hydropower plants The grid of the future. The power grid of the future will not be made up of a few large power plants but rather of many small ones. As part of the transformation of the German energy sector, plants such as the g-box are increasingly gaining in importance in intelligently networked energy systems – so-called virtual power plants – due to their distributed nature, controllability and predictable availability. With a g-box you can also make a contribution to a stable, clean energy supply of the future.

Integration in virtual power plants. Distributed, renewable energies such as solar or wind power have one huge disadvantage: they are only available when the sun is shining or the wind blowing. The solution for secure, needs-based provision of electrical energy by distributed generators is known as a “virtual power plant”. Many small distributed electricity generators are linked together using intelligent control technology. The grid operator can access the power provided. If electricity is needed, the virtual power plant controls the immediate use of the connected systems. In a network...

Areas of use for the g-box. The g-box by 2G has already demonstrated its strengths in many places, e. g. in residential buildings, office and administration buildings, nurseries, schools, hotels, senior citizen centers, hospitals and in a wide variety of industrial and commercial businesses. Nowadays, virtually every business is suitable for the use of cogeneration. The g-box. Perfect for hotels.
