A European directive has forced the City of Esch to outsource its electricity supply services to a private company. Thus, in 2007, the limited partnership Sudstroum was created, which took over all the customers of the City of Esch on 1 July 2008; from that date, it has ensured the supply of electricity to customers. In addition, Sudstroum becomes the network manager of the City of Esch. Since 1 July 2008, the network infrastructure has been managed and operated in cooperation with the City of Esch.
In addition, Sudstroum also supplies several customers in each of the twelve cantons outside of its own power grid.
From the start, Sudstroum has strived to offer its customers competitive rates, always selling electricity from renewable energy sources to both private and professional customers. Over time, other services have been added. This is how Sudstroum is one of the first companies to offer the Digicash payment service in Luxembourg.
From 2015, the offer has been supplemented by a free energy advice service for Sudstroum customers.
Since 2019, Sudstroum has also been offering interesting financing solutions for the installation of photovoltaic installations, to both private and professional customers.
In addition to power issued from 100% renewable energy, Sudstroum offers a variety of other services, including internet & TV ( in Esch/Alzette), charging cards for electric vehicles (EV), solar plants and even free energy saving advice.
Sudstroum is positioned as a telecommunications service provider, inherited from the City of Esch. Our goal is to provide high quality essential services at reasonable prices.
In addition, Sudstroum has been interested from the beginning in research and development activities in the field of renewable energies. Since 2010, Sudstroum has been collaborating closely, particularly for questions related to photovoltaic energy, with the national research institute List (formerly Henri Tudor). In the field of wind energy, Sudstroum has followed various avenues, which, at present, however, have not produced any results. On the other hand, Sudstroum has succeeded in setting up several photovoltaic installations operated by the company itself.
Since Sudstroum belongs 100% to the City of Esch, the profit made goes exclusively to the population; it is used to carry out social, cultural or sporting activities, of which customers who do not live in the municipality of Esch can also take advantage.
