Our renewable energy roadmap
Together with its shareholder municipalities, SUDenergie is launching the SUDWAND wind power project to generate local green electricity.
The first 11 photovoltaic installations are built. 13 more installations follow in 2020. Larger installations are in the planning phase.
As a sustainable energy company, it was only logical to change our name from SUDGAZ to SUDenergie.
As a responsible player in the energy market, SUDenergie has been increasingly committed to actively promoting the energy transition since 2015.
We want to become a future-proof energy supplier in Luxembourg while helping to shape the expansion of renewable energies.
