Our collaborators and our partners

After successfully implementing several local energy and innovative pilot projects, I chose Tilia to help the public sector implement the energy transition. I appreciate Tilia’s continued and strong commitment to helping his clients develop innovative projects that add value to their regions. Tilia mobilizes technical, financial and legal expertise from its partners, coupled with extensive knowledge of the public environment and development of area projects.

Aymar de Germay

Director of Territorial Communities Development

Rising energy costs, higher levies and new requirements demanded a concept that provides economic supply, prevents extreme price fluctuations and is environmentally friendly. Energy supply is not our core business, which is why our partner Tilia has developed a tailor-made energy concept that convinced us. As part of a cooperation investment, Tilia Solutions GmbH implemented the new heating center, which consists of two highly efficient combined heat and power plants, as well as a ventilation and absorption refrigeration plant. The entire plant produces the complete heat and cold and about 50 percent of the required amount of electricity. We are very satisfied with the result.
