Ecological conversion of the Dudelange energy plant

Since the year 2000, the Dudelange energy plant has been supplying via an underground heating network the “Brill” district and several buildings in the vicinity of the energy plant, such as the Centre Hartmann, the Lycée Technique Nic. Biever, the outdoor swimming pool, the Brill and Wolkeschdahl schools, the J.F. Kennedy Stadium and the CIPA Dudelange with heat.

After 20 years, the heat supply contract between “Cogénération Dudelange Brill S.A.” and LuxEnergie expired.

In a feasibility study, the installation of a biomass energy generation plant based on wood pellets was selected as a sustainable and economically viable solution for the future.

LuxEnergie won the resulting public tender in 2020.

Total heat production will remain unchanged at 10.5 MWh/a after the conversion.

To cover the base load, the two existing CHP modules will be replaced by two wood pellet boilers. This ensures that at least 83% of the heat will be produced from renewable sources in the future, which will reduce the annual CO2 emissions by about 2,000 tonnes.

The peak loads, which mainly occur in winter, will continue to be covered by the two existing gas-fired boilers.

The renovation work will begin in January 2021. Commissioning of the new plant for another 20 years is planned for October 2021.
