A local partner committed to Luxembourg’s energy future
Together with its 14 shareholder municipalities, SUDenergie works to support the public interest and contribute to a more sustainable future. Responsibility towards both society and the environment is at the heart of the company’s long-term approach.
Since 2015, SUDenergie has invested steadily in the expansion of renewable energy across Luxembourg. By developing sustainable projects, the company helps increase the production of locally generated green electricity and supports the country’s energy transition.
Working in partnership with municipalities, businesses and a wide range of stakeholders, SUDenergie has successfully delivered several large-scale solar projects. These include installations developed through public tender programmes as well as citizen participation schemes that enable residents to play an active role in the transition to renewable energy. Thanks to this collaborative approach, more than 87 photovoltaic plants have already been commissioned.
SUDenergie is also helping to expand wind power generation through the SUDWAND project. Two wind turbines are currently in operation, while a third is under construction, further strengthening Luxembourg’s renewable energy capacity.
The development of SUDenergie dates back to 1899, when a gasworks was built in Esch-sur-Alzette by the Carl Francke company from Bremen. At the time, the gas produced – known as town gas – was toxic and less efficient, and was mainly used for public lighting. The network was quickly expanded to other surrounding municipalities.
The establishment of the Compagnie Générale pour le Gaz et l’Électricité in 1923 marked the next phase of growth, leading to the company being taken over in 1953 by six Luxembourgish municipalities. In 1966, local gas production was discontinued, and gas was henceforth imported. By 1972, the entire network had been converted to natural gas, which is both safer and more efficient. Just three years later, additional municipalities joined the shareholder group.
In 1989, the company was renamed SUDGAZ S.A., and more municipalities became shareholders. Today, the company operates under the name SUDenergie and has 14 shareholder municipalities.
Over these 125 years, the company has continuously evolved – always with the same mission: to provide its customers with energy reliably and under the best possible conditions.
