Construction start for ALEGrO

30.10.2018

As a responsible and future-conscious transmission system operator (TSO), TSCNET shareholder Amprion is committed to the European Energy Union. An outstanding project in this respect is the Aachen Liège Electricity Grid Overlay (ALEGrO), the first interconnector to directly connect the German and Belgian electricity grids. The European Project of Common Interest (PCI) is being implemented jointly by Amprion and the Belgian TSO Elia. Following a pleasingly short approval procedure, the starting signal for ALEGrO was given today in the commercial area of the west German city of Aachen. Here, Amprion celebrated the start of construction with a symbolic turning of the first sod.

The ceremony was attended by numerous high-level representatives from politics, business and public life, among them Armin Laschet, Minister President of the German state of North Rhine-Westphalia, who commented: “ALEGrO is a milestone for cross-border power supply and not only connects North Rhine-Westphalia and Belgium, but also brings Europe closer together.” Dr. Klaus Kleinekorte, CTO at Amprion, complemented: “ALEGrO becomes part of the EU’s electricity highway system, which links the centres of renewable energy generation with the major consumption centres in Europe.”

For the entire ALEGrO route (about 49km in Belgium and 41km in Germany) underground cabling will be used. The cable laying work is accompanied by the installation of converters at the ends of the cable in Oberzier in Germany and Lixhe in Belgium, which convert AC into DC and vice versa. ALEGrO will have a transmission capacity of 1,000MW and thus provide urgently needed grid capacities for cross-border electricity flows. At the same time, ALEGrO will also strengthen supply security in the Aachen-Cologne region.
