The roots of EEG GmbH date back to AEG . In 1982, the energy department for cogeneration plants in Bremen was founded . As a market leader in this area several employees from this time are working for EEG GmbH today. In 1998 AEG T & D was acquired by the French state-owned ALSTOM T & D . In 2004 the company was transferred to the state-owned AREVA Group . In 2015 the AREVA Group decided to withdraw from the renewable energy sector in Europe. After this decision Dieter Reineke , Carsten Hacheney , and Carsten Lange decided to form their own business, and to give experienced staff a new job . From this arose the present EEG GmbH .

Our past accumulated experience: of power plants for biogas , biomass and natural gas applications are today located at a new location in Sottrum . The team has been involved in the implementation of more than 150 projects, comprising natural gas, biomass and biogas plants and heat and power plants. In all these projects, we were involved as a general contractor and have worked on all key stages from planning and project management to commissioning and handover, and ensuring completeness in the scope of supply. Please feel free to contact us and we will then match your project with the references that we have worked on. As our references have been developed by the predecessor companies mentioned above, we can provide no list to you here. Please find here an example of a biomass plant where our personnel were involved in the project execution. By clicking on the image a 360 ° tour of a biomass power plant is started.
