Our Vision

Key ideas, driven from our experience, inspired the foundation of Tilia in 2009.

First, we believed that new infrastructure and utility services would gradually develop through decentralised dynamics, at the local level. And that enhanced local cooperation could enable stakeholders to address rising environmental challenges, while providing more efficient services to end users and communities and stronger citizen empowerment.

We also foresaw that new governance and management models would be required to face those challenges. Efficient, decentralised cooperation between industries, citizens and municipalities is required in order to upgrade and better connect energies, city planning, water and waste cycles, mobility. We steered some pioneering projects in this field, and we still do.

Tilia brings focus and key competencies to those stakeholders, in strategy, conception and implementation. In a multi-disciplinary, delivery driven perspective, we catalyse local potentials into projects which bring value to communities, and to our clients and partners.

Our work is based on partnerships with our clients to develop innovative infrastructure and
services, and to enhance the operational and environmental performance of communities, utilities and industries.

Our models range from project management and consulting to joint realisation and co-investment in jointly designed projects. They are always aiming at implementing change and achieving concrete, measurable results.

Our Model
Tilia’s headquarters are in Europe (Leipzig and Paris). Most of our European projects are located in Germany and France, but we also have projects in other EU countries, some of them steered by EU institutions. The headquarter of our subsidiary decon international is in Bad Homburg vor der Höhe, close to Frankfurt am Main.
The Tilia group has several projects in Asia. Our subsidiary decon international is active in the region since 1985 and has implemented more than 35 projects in the fields of power distribution, renewable energies and wastewater in countries such as China, the Philippines, Taiwan, Thailand and Vietnam. Tilia has offices in Vietnam, where we started in 2015 to modernise and optimise sanitation and waste water treatment services in communities, in cooperation with the German Agency for International Cooperation (GIZ). We now develop new cooperations with Vietnamese partners, both public and private, in the field of renewable energies, energy optimisation, water and waste water treatment.
For our subsidiary decon international, Latin America has emerged as an important key market. Starting with electricity projects in 1975 in Colombia, the activities of decon international have been expanded to other countries including Argentina, Bolivia, Brazil, Chile, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, and Venezuela with a focus on projects in the energy sector, as well as rural water supply and sanitation and the corresponding policy advice. Overall more than 100 projects have been implemented in this region. Currently decon international is working on projects in Peru and Nicaragua. A representative office is located in Managua, Nicaragua.
By implementing more than 100 projects since the 1990s the CIS-states have become an important region for our subsidiary decon international. Counting with a permanent representation in Yerevan, key countries are Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan. Projects have been mainly implemented in the energy sector, for instance energy supply and saving programs policy advice Other projects took place renewable energies and in the fields of wastewater, solid waste management and urban and rural water supply.

The almost 100 projects were mainly implemented in the fields of electricity, rural electrification, energy efficiency, drinking water supply and sanitation.

With around 100 projects, decon international’s activities in the MENA-region are of major importance since the 1980s. Projects have been carried out in Algeria, Egypt, Morocco, Iran, Iraq, Israel, Lebanon, Libya, Palestinian Territories, Syria and Tunisia with a focus on energy rehabilitation, infrastructure, renewable energy, wastewater treatment and sanitation. Its permanent office is located in Beirut.
In 1992 decon international implemented its first project in Albania and extended its radius of action in the following years to Bosnia Herzegovina, Bulgaria, Macedonia, Montenegro, Kosovo and Serbia. The focus is on the energy sector with projects of electricity supply, promotion of renewable energies, energy efficiency, power transmission and distribution. Moreover, decon international implemented wastewater treatment projects and provided policy advice for water and waste regulation.

Tilia has a focus on its “native” markets: Germany and France. But we also like to build with other communities, industries and stakeholders worldwide: smart cities are not a one-size-fits-all model!
