Amprion and Elia Award Siemens with HVDC Contract for ALEGrO Interconnector

Erlangen/Dortmund/Brussels, 2016-Nov-29

  • Contract volume €273 million including a five-year maintenance agreement
  • Two converter stations at both ends of a 90 km underground cable with a capacity of 1000 MW
  • ALEGrO creates value for society: security of power supply, renewable energy and European market integration

Amprion and Elia have signed yesterday with the winning contractor Siemens who will deliver the two high-voltage direct-current (HVDC) converter stations for the first electricity interconnector between Germany and Belgium. The order volume for Siemens including a five-year maintenance agreement amounts to €273 million. The German Transmission System Operator Amprion and the Belgian Transmission System Operator Elia join forces to deliver the Aachen Liège Electricity Grid Overlay (ALEGrO), a major infrastructure project, part of the European electricity highway system. Using 90 km long underground cables ALEGrO will connect the Belgian and German high-voltage electricity systems. The converter stations will transform AC to DC and DC back to AC on the other side of the link. Siemens will be responsible for the system design and the supply, installation and commissioning of all components for both converter stations using HVDC Plus technology, which is highly controllable and brings operational benefits to both transmission systems. ALEGrO is scheduled to commence commercial operation in 2020.

The European Commission has designated the ALEGrO project as one of its projects of common interest. ALEGrO contributes greatly toward helping the European energy markets grow closer together. The renewable energy sources should also encounter fewer bottlenecks on the grid and maximize their production. The high voltage link can transport energy up to 1,000 MW to either Belgium or Germany with a high degree of controllability of the energy flow. It will transport enough electricity to power half a million homes.

Klaus Kleinekorte, Managing Director of Amprion: "ALEGrO will make the European electricity network even more secure and powerful. We can control the power flow of the cable with a high degree of accuracy and adjust the volume of electricity and flow direction."

Markus Berger, Elia Chief Officer Infrastructure: "Inteconnections based on innovative convertor technology will allow bottlenecks in the European transmission network to be gradually decreased. Allowing for more flow exchanges will improve the working of the market and should lead to lower energy prices."

Ralf Christian, CEO of the Siemens Energy Management Division: "ALEGrO will feature state-of-the-art converter technology. The HVDC Plus solution from Siemens assures highest reliability and efficiency in transmitting power independent from specific weather or grid conditions. HVDC Plus masters the growing challenges from fluctuating renewables."

ALEGrO will increase energy security for both countries and support the integration of renewable energy. On top of the additional transport capacity ALEGrO is offering, the fast control and protective intervention in the power converter will allow the TSOs to adjust the volume of electricity and flow direction, for a better efficiency of the electricity grid.

On September 29 Elia and Amprion already signed a €125 million contract with Silec Cable to build the 90km underground cable.
