The Centre

In earlier times, a linden tree (lat. tilia) was often found at the centre of a community. Men met to talk, women to sing and young people to meet. Dance Festivals also took place under lindens.

Your partner in energy, water and environment

Tilia is the partner of cities, communities, public and private utilities, industrial businesses and co-investors, who seek to develop new projects, make new investments, improve their operations, redefine their strategy and manage increasingly complex challenges in the fields of energy, water and environmental services.

The model created by Tilia is flexible; it can range from consulting and project management support to jointly realized projects eventually leading to joint investments.

We cover all topics related to strategy, governance, operational optimization and development of new investments.

Our model is always based on a strong commitment to our customers, enabling them to achieve jointly defined concrete objectives.
Founded in 2009, based on an international experience and a common vision of the future of utilities and public services. Today Tilia and its subsidiaries employ almost 100 employees and count more than 500 contractual references in 24 countries.

European Commision publishes Tilia study on efficient district heating and cooling systems

We believe efficient district heating and cooling systems can provide an evolutive backbone to balance energy transitions. Tilia has prepared the new report of the JRC on Efficient district heating and cooling in the EU, providing an in-depth analysis of DHC systems in Barcelona, Brescia, Copenhagen, Gram, Hafencity (Hamburg), Paris-Saclay, Stockholm and Tartu”.

Abstract of the study:
Based on a holistic case studies analysis of 8 efficient district heating and cooling systems in different European Member States (Denmark, Estonia, France, Germany, Italy, Spain and Sweden), the study identifies the key factors enabling to develop high quality, efficient and low-carbon DHC systems, discusses how these key success factors can be replicated in the EU and provides a better view on the role and features of these systems, which can provide an evolutive backbone to balanced energy transitions. Finally, it suggests some potential policy guidelines to support their deployment.

Smart Border Initiative: A Franco-German cross-border energy optimisation project

Tilia has jointly designed with dena (the German Energy Agency) a showcase Franco-German project aiming at creating a replicable European model that will pave the way for more cross-border cooperation in energy systems: the Smart Border Initiative (SBI). DSOs from both sides of the border -Enedis in France and Innogy in Germany- are also co-steering this project, in which 18 industrial partners from both countries and beyond have expressed interest, after contributing to its design.
Integrated and optimised local energy systems will play a key role in achieving the energy transition objectives set by France and Germany, in line with the Energy Union’s goals, and contribute to ensuring a secure, affordable and climate-friendly energy supply in the EU. In order to capitalise on the German and French expertise and experiences in developing such systems, both Governments have decided to launch this common initiative to identify and structure a cross-border energy optimisation project. The project is based on a multi-energy smart grid concept (i.e. coupling electricity distribution, heating and mobility).
Tilia, in close cooperation with Enedis, Innogy, dena and all other partners, have jointly shaped the project which has been approved by both governments, and for which EU co-funding has been sought, as the project presents the features of a Project of Common Interest.

Tilia supports Lyon in becoming a smart city

Tilia works alongside the City of Lyon, who has developed some of the most innovative projects in the field of digitalization of urban services and smart, in order to develop, organise and implement of the next steps of its smart city services and infrastructure.

Lyon first has developed several smart grid demonstrators together with many national and international partners (Lyon Smart Community, Greenlys, Watt et moi, Smart Electric Lyon, Confluences…) and is now paving the way to the next steps through the Lyon Living Lab project. This project will enable the Greater Lyon, its grid operators and other stakeholders to use the energy data to manage more efficiently its grids and to develop new services for the benefit of end users, while strengthening the local economy and its energy transition.

Tilia also helps the Metropolis in developing energy innovation projects which create value, especially in partially developing renewable energy production within industrial sites.

decon international has been a subsidiary of Tilia since 2016

Decon international provides an extensive package of engineering and advisory services worldwide. It supports projects in the fields of energy, energy efficiency, water, waste water, and smart cities. Decon has successfully realized hundreds of projects in more than 140 countries over the last few decades.

Our name

Tilia is the Latin name for the linden tree, a tree with a sound root structure, a sturdy trunk and solid branches. It is a tree which grows and flourishes consistently as long as it's properly planted and taken care of.
