“Storage” of wind energy
Connecting Norwegian hydroelectric power with German wind power provides benefits for both countries. Whenever a surplus of wind energy is produced in Germany, for example, it can be transmitted via NordLink to Norway. The reservoirs in Norway then serve as natural storage for wind energy as the water remains in the reservoirs. Conversely, Germany can import hydroelectric power from Norway when demand is high. The HVDC interconnector will have a capacity of 1.400 megawatts (MW) and will be in-stalled between Tonstad, Norway, and Wilster (Schleswig-Holstein), Germany. NordLink is scheduled for commissioning and trial operation in Q4/2019, and after the trial period the interconnector will go into commercial operations in 2020. The interconnector com-prises a total investment volume of approximately EUR 1.5 - 2 billion Euro. Further information: http://www.tennet.eu/de/index.php?id=1146&L=2
NordLink will be realised by the Norwegian TSO Statnett SF and DC Nordseekabel GmbH & Co. KG, each with 50% ownership. TenneT TSO, and German promotional bank KfW both have shares of 50% in DC Nordseekabel. DC Nordseekabel is responsible for the construction of the German part of the project, including permits.
