• Move Offshore
• Single European electricity market
• Security and sustainability of supply
• Carbon neutral Europe by 2050
Why the Supergrid?

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

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
