Our companies
Four specialists. One mission.
Everything from one source.
AES Holding GmbH in Augsburg, Germany, brings together engineering, products for ships, projects for power stations and mobile power. Founded by Dr.-Ing. Thomas Spindler, the group works on one goal: making large diesel engines cleaner and more efficient.
The holding
AES Holding GmbH
Alternative Energy Solutions Holding GmbH (AES) is a group of engineering and project companies headquartered in Augsburg, Germany. AES serves as the parent company of the group and unites all group companies under one roof, defines engineering standards and bundles technology development in one place.
AES is the sole owner of all operating companies of the group listed below. The holding company itself is wholly owned by the founder Dr. Thomas Spindler.
Each group company operates independently in its own field and is managed by its own management. The managing directors and commercial register details of all companies are listed in the imprint.
How the group works
From one source, run separately
AES Holding GmbH unites all companies. In daily business they work separately: each has its own team and its own contracts. You always work with the company that knows your field best.
1 · Plan
Every project starts with AES Engineering & Consulting: pre-study, design and the right product for your engine or site.
2 · Carry out
The specialist takes over: AES Maritime Projects for ships, AES Power Projects for power stations, AES Mobile Power for power barges.
3 · One contact
You keep one contact person from the first talk to the running system.
Who we are
Who does what
Every project starts with AES Engineering & Consulting: our engineers in Augsburg advise you, design the solution and recommend the right product. Depending on the product and where it is used, one of our specialised companies then takes over sales, project management and delivery.
