Transmission line to run 387 miles between Norway and Germany

Transmission line to run 387 miles between Norway and Germany

A plan to link the German and Norwegian power grids will become Europe's longest high-voltage direct current (HVDC) power grid connection. Swiss company ABB won the $900 million contract to complete the project, which is expected to take five years to complete. The company will then be allowed a five-year service agreement. ABB, along with a consortium that includes utilities Statnett and TenneT, will supply on-shore HVDC converter stations and the Germany cable system to connect the two grids -- creating the NordLink project. The link between the two grids will be 623 kilometers (387.1 miles) long. "We are very pleased to be working with TenneT and Statnett on another landmark project that will support the
integration of the European energy market. The smart combination of renewable power generation, e.g. solar
and wind in Germany and hydro-electric in Norway, demonstrates that we can technologically enable a
sustainable green energy policy across Europe," said ABB CEO Ulrich Spiesshofer.

The project has been designated as one of the European Commission's projects of common interest to help the energy market in the European Union. It will allow renewable energy -- including wind and solar -- to be transmitted from Germany to Norway, with hydroelectric transmitted from Norway to Germany. The link will transmit power at 1,400 megawatts (MW).

"The NordLink project once again demonstrates ABB's commitment to the efficient use of renewables; we are
bringing clean power to millions of people and supporting the energy policies of Germany and Norway," said Claudio Facchin, President, ABB Power Systems division.

The project will encompass two 525 kilovolt (kV), 1,400 MW converter stations. One station will be located near Tonstad in southern Norway and the other station will be located near Wilster in northern Germany. There will also be a 525 kilovolts (kV) mass impregnated (MI) cable system in Germany, which includes 154 kilometers (km) of subsea and 54 km of underground cable.

In February, a 40-mile transmission line being built across the France-Spain border was officially
inaugurated. The line had a similar goal -- to transfer energy sources from one country to the other. The NordLink project is scheduled to go into commercial operation in 2020.
