9. Supergrid Phase 1 – Design Drivers Offshore Wind  25-30 GW 2020 in the North Sea (UK, Germany, Belgium) UK Network Congested North Germany – High Wind Penetration Hydro balance capability

10. TUOS : 1,55 - 4,67 c/kWh Socialised: 0.23 c/kWh Supergrid Phase 1 - Cost Project Financing:  €28 billion (2010 value)  30 % RoE  6 year building time, 40 years of operation  23GW of Wind Generation Connected  Capacity factor:  40% - if the wind alone trades on the system  90% - when wind and other energy/service providers use the network

11. Technology Today (2015): HVDC – VSC  1 GW  Losses < 1.5% HVDC Cables  XLPE – 300kV  MI (Oil) – 500kV

12. Supergrid Technology (2015): The SuperNode – Hybrid AC/DC Design HVDC based on VSC (Voltage Source Converter) technology

13. Technology Developments Improved Converter Design  <<< Losses  >>> Power Cable  >>> XLPE Voltage Capability Multi-Terminal Wide Area Control System System Dynamics  Inertia  Fault Performance DC Switchgear Onshore Transmission  GIL  Superconductivity
