The Safeguard

“Germans and Slavs have traditionally considered the linden (lat. tilia) to be a holy tree. Germanic Sagas hold that lightning will not dare strike a linden because it was dedicated to Freya, wife of Wotan, father of gods.”

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.


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.


The European Commission (Directorate General, Joint Policy Center) choses Tilia to lead a European survey on district heating and cooling grids and markets, and their contribution to efficient energy transition policies

As the energy transition focuses on holistic energy efficiency policies at the local level, more attention is paid to the various advantages of efficient district and heating and cooling networks. They appear, in many respects, as a potential backbone of coherent local strategies, mainly due to the fact that they enable local authorities to combine a variety of energy efficiency and decarbonisation leverages, whilst providing efficient services to end users. At one end, they can be supplied by a variety of local renewable energies, ranging from various biomass fuels to geothermy, but also including biogas from waste or sludge, often through cogeneration, and other potential sources. At the other end, they are closely linked to efficiency policies in buildings, both as regards new construction and renewals. They also provide numerous possibilities for energy recycling and exchanges, and will be increasingly connected with electricity and gas grids, thus gradually enabling real time arbitration between multiple energy sources to supply specific local needs, and helping manage the costs and technical challenges of the instability linked to the increased share of renewables injection in electricity grids.


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.
