\nA little-known industrial chapter with international implications<\/h2>\n\n\n\n

To mark its 125th anniversary, SUDenergie is funding a research project<\/a> in collaboration with the C\u00b2DH to explore its history. The SUDenergie story, which began in 1899 with the building of a gasworks in Esch-sur-Alzette and the use of coal gas for street lighting, is linked to the national and international history of the gas industry through the companies that were active in Luxembourg from the 1890s onwards \u2013 mostly German but also French \u2013, as well as the contribution of large numbers of migrant workers from northern Luxembourg and neighbouring Germany.<\/p>\n\n\n\n

The project funded by SUDenergie is therefore an opportunity to shed new light on both industrial history and the history of migration in Luxembourg from a fresh angle. While gas is now mainly used for heating, it was initially produced for public lighting \u2013 and it was very popular with local authorities, given that the alternatives were oil or as yet relatively inefficient electric lighting. The story of SUDenergie shows how the use of gas developed (from coal gas, initially produced locally and then remotely, to imported natural gas) and also illustrates the diversification of energy production over time, as reflected in the different names of the company: Compagnie g\u00e9n\u00e9rale pour le Gaz et l\u2019\u00c9lectricit\u00e9, then Sudgaz, and finally SUDenergie.<\/p>\n\n\n\n

The story of SUDenergie, from the building of the first gasworks in Esch-sur-Alzette and Differdange to the current diversified energy company owned by fourteen local authorities, is now available via the website 125joer.sudenergie.lu<\/a>. The site presents the main milestones in the company\u2019s history and also features interviews, archives and lists of employees at the gasworks in Esch-sur-Alzette, Differdange and Kayl from the 1900s to the 1950s. Two interactive maps<\/a> indicate where the workers came from and provide additional information about them, representing a useful tool for research on migration and genealogical history.<\/p>\n\n\n

The research showcased on the website, which will also serve as the basis of a monograph, is led by Professor Denis Scuto<\/a> and conducted by postdoctoral researcher Philippe Blasen<\/a>, with valuable support from students Sophia Guarda, Naomi Chiril\u0103, Lejla Osmanovi\u0107 and Mikko Zaglaniczny.<\/p>\n\n\n\n
