The history of G-TEC – a company founded on experience and expertise

Extensive engineering know-how is a key requirement for delivering the most effective energy management plan. Experience has shown us that successful energy advice must always be based on professional engineering expertise as this is the only way to guarantee that the best outcome will be achieved. This is the principle that we have been following for 30 years now – no matter how complex your project may be. In 2023, we took another step along our path to systematically further develop our business by founding G-TEC Consulting GmbH, a new G-TEC Ingenieure GmbH company that is focused on expanding our ‘industry and commerce’ business.

We are here to help!
