    "Le monde est à l’énergie" (the world belongs to energy), so reads the above statue welcoming travellers and visitors to the main station of Marseilles. Actually, since the beginning of the anthropocene and even more so from the industrial revolution onwards, supply of fossile fuels, power distribution and electricity supply have become crucial issues for human development.

    So the debate on fossile fuels, their limitations as well as the increasing challenges of their finite nature and supply instability has become virulent, both in political and economical terms.


    So the idea of endless energy provided by sun and wind is even the more convincing and, for us, both thrilling and a necessity! The contrast between the almost universal availability of solar and wind resources and the strange and often outdated discussion on their cost and impact seems thus highly surprising and paradoxical.


    Finding viable solutions to this paradoxon is the reason why we, a group of young engineers and renewable energy professionals, created TCO Solar: TCO combines broad international competences and management skills with longstanding expertise in the solar and wind industry to the service of renewable power plants. Thus our mission:




    We aim at an even more efficient use of natural renewable power sources both to the benefit of economy (owner, supplier, investor, bank, etc.) and ecology (be they the natural environment, or more narrow local and regional stakeholders).


    Our home ports are Marseilles, at the shores of the Mediterranean and Hamburg, on the North Sea. The former is our technical and administrative headquarter, at the core of the Mediterranean Sun Belt. The latter is the capital city of Renewables in Germany and, perhaps, the world: the most prestigious banks, the most important investors, some of the world industry leaders are as well based here, while the city is at the forefront of renewable energy policies with her recent repurchase of her electricity grid and a newly recreated municipal utility which supplies her energy solely from renewable sources.


    As harbours and places for most diverse encounters and meetings, both Marseilles and Hambourg welcome the visitor: so do we at our premises!

Our TEam


At TCO we are a team of dedicated people. Either as engineers or managers, we share an international- and open-mindedness as well as strong and long-standing local knowledge. We do have flat hierarchies and work as a team with all employees.
