About us

We are a fully integrated manufacturer of CHP plants

In our own production facility in Leipzig, we manufacture gas engine CHP plants with electrical outputs ranging from 50 to 4,500 kW.
Our CHP plants stand for reliability and robustness and are as strong as a mammoth.

Customer satisfaction

The satisfaction of our customers is the core component of our corporate philosophy.

Construction and sale of cogeneration plants are a complex project business. The feasibility requires a high level of experience and know-how.

We have realised projects of approximately 250 MW and are in charge of 1,000 CHP plants in service.

To improve continually we would be happy to receive your feedback.


We build sustainable cogeneration solutions for decentralized power supply.

The performance of existing environmental policies, and the desire to achieve higher levels of efficiency with our products have high priority. We focus on innovative combined heat and power technologies.
With foresight, we are advancing the renewable energy policy to reduce CO2 emissions.

    Our CHP plants are built according to the highest quality standards and embody the premium quality of German engineering.
    Our CHP plants are a profitable investment for our customers.
    Our CHP plants are climate-friendly. The use of combined heat and power stands for environmental responsibility.

We take responsibility for our partners and customers, the society and the environment .


Our brand image is the mammoth. Each SES cogeneration unit has the characteristics of a mammoth: reliability, robustness, a good performance and a long life.

The mammoth was a peaceful animal and fed exclusively on plants. It lived within the social mammoth family and was perfectly adapted to its environment. So it could populate over hundreds of thousands of years wide areas of the earth.

The mammoth had an efficient thermal insulation and survived the ice age. Its massive physique, its size and the specially hardened tusks protected it from predators. A mammoth could become up to 65 years old.

A CHP plant from our company is like a mammoth. Only the best materials are used. High-quality components guarantee high quality, long life and energy efficiency. Due to our expertise in the field of sound insulation our products can be used in all fields of application.

Most likely the mammoth is a victim of a bygone climate change. Today it is the perfect symbol for clean energy.

The energy revolution is a mammoth task! With our combined heat and power plants as strong as mammoth.
