\ 7 NordLink Impressions Norway & Germany
\ 8 NordLink Germany-Norway Norway can export its energy surplus . Germany can export energy Facilitate European Market to Norway when the wind is intergration blowing on the continent during dry season
The NordLink interconnector will stabilize electricity prices and facilitate a more predictable energy market
Add welfare to the society

HVDC Technology
HVDC High Voltage Direct Current (HGÜ) Voltage Source Converter – VSC Transmission from AC to DC and vice versa AC ~ DC -
DC - AC ~
Why HVDC?
. AC cable transmission links have a maximum distance of ~ 100 km . HVDC avoids the heavy currents required to charge and discharge the cable . For longer distances HVDC cable transmission is the only possible solution . Active and reactive power independently and rapidly controlled . Black start possible
\ 11 NordLink Schematic Converter Station
Area ~ 200m x 200m

Mass Impregnated Cables
Why mass impregnated cables? only proven technology for voltage level ≥ 500 kV used for HVDC power cable since 1954 environmental friendly - no liquids or gases are released
NordLink Facts
rated voltage U0= 525 kV overall cable diameter up to 128 mm weight in air up to 70 kg/m total cable weight ~ 70.000 t

TenneT Interconnectors
. BritNed cable to the United Kingdom . NorNed cable to Norway . NordLink cable linking Germany to Norway (planned) . COBRA cable linking the Netherlands to Denmark (in development) . Interconnector linking Doetinchem in the Netherlands to Wesel in Germany . Increasing capacity planned of the interconnector Meeden (NL) – Diele (GER)
TenneT contributes to the development of an integrated NWE electricity market by supporting interconnection countries.

NordLink Conclusion
The exchange of power enabled by NordLink will… increase security of supply for the German and Norwegian grid stabilize electricity prices and facilitate a more predictable energy market facilitate European market integration transmit hydroelectric power to the Bavarian industry from Norway or wind energy from north Germany. allow exchange of 1400 MW renewable energies
