Our shareholders

The share capital of LuxEnergie amounts to €10 million and is divided between the following shareholders:






Responsibility for the environment

We have set ourselves the goal of preserving nature. Because only a consistent focus towards sustainable management will ensure the future and create added value for all those involved: for customers, employees, and the environment.

We want to use fossil fuels responsibly. For this reason, it is particularly important to us to use fuels in our plants effectively.

In recent years, we have significantly promoted the use of biomass in our plants and we will continue to do so.

Renewable energies have been used in new plants from the very beginning. In addition, we have converted many of the plants that were previously supplied with fossil fuels to renewables.

For example, the Kirchberg Plateau heat network became green in 2017 because we invested in a new biomass-fired combined heat and power plant. This conversion alone can save 22,000 t / CO2 annually.

We therefore actively contribute to environmental protection by reducing the consumption of primary energy and CO2 emissions through the appropriate technologies. This is possible thanks to increased efficiency of the systems – the most important and at the same time indispensable prerequisite for ensuring our future quality of life.

… and, of course, we constantly are committed to finding further new approaches that make use of innovative energy systems.


The development of the company

The rapid development of the Kirchberg Plateau at the end of the 1980s required congruent planning of the energy supply and urban development.

Therefore, the companies Paul Wurth, Luxconsult, Omnitec and the “Stadtwerke Saarbrücken” joined forces and formed a working group to carry out a feasibility and economic study with regard to the construction and operation of an independent energy system on the Kirchberg Plateau. Based on the results of the working group, the decision was taken to establish a company to promote cogeneration in the Grand Duchy of Luxembourg: LuxEnergie.
