  1. Offshore Wind and the European Supergrid Joe Corbett, Head of Technical Services Mainstream Renewable Power Representing: Friends of the Supergrid

  2. Offshore Wind Installations 2010 Source: EWEA http://www.ewea.org/index.php?id=1861

  3. Offshore Generation Location up to 2010

  4. Foundation Design Evolution

  5. Offshore Research • Hywind – Spar Type Floating Foundation • Norway 200m • Statoil • Blue H – Tension Leg Platform (TLP) • Netherlands 100m • Windfloat – Semi Submersible • Portugal 40m • Offshore Wind Accelerator • Carbon Trust + 8 Developers • Wind Analysis • Electrical and Foundation Design • Operation and Maintenance

  6. Offshore Trends Turbine Size Trend Source EWEA Principle Power’s Windfloat Design

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

  8. 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

  9. 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 TUOS : 1,55 - 4,67 c/kWh Socialised: 0.23 c/kWh

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

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

  12. 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

  13. Policy and regulatory aspects at a glance • Master Plan: Entso-e • One Operator: ISO • One Grid Code: Entso-e • One Regulator: ACER
