EMVT 12 september - Han van Asten - TenneT

  1. 1. Connect Offshore Wind 12 September 2013 ir. Han van Asten, Programma manager TenneT Rotterdam / Arnhem, 12 September 2013 Connect Offshore Wind 'Met EMVT op Zee'
  2. 2. Connect Offshore Wind 12 September 2013 Met EMVT op Zee: Connect Offshore Wind 2 • Introduction TenneT • Video Installation DolWin Alpha • TenneT Offshore Germany • Regulatory Framework & Licensing • Technology & Industry • Comparison Germany - Netherlands
  3. 3. Connect Offshore Wind 12 September 2013 3 About TenneT • TenneT is responsible for connecting electricity producers to the high-voltage grid • TenneT does not distinguish between different producers and is obligated by law to connect all parties to the grid Additional tasks • Maintaining the balance between electricity supply and demand (50 Hz) • Ensuring the security of supply • Importing and exporting electricity and maintaining the programme responsibility system
  4. 4. Connect Offshore Wind 12 September 2013 4 4 From • Stable, predictable (price-driven) energy generation • Maintenance and (limited) replacement • Focus on technology • Local markets, separate price zones • National focus and regulation To • Fluctuating (nature-driven) energy generation • Large-scale new construction • Technology and market • North-Western European market, price convergence • Grid planning and regulation at European level Radically changing role and tasks of TSOs New roles and tasks of TSOs
  5. 5. Connect Offshore Wind 12 September 2013 5 Two grid operators – One company As Europe’s first cross-border grid operator, TenneT has been safeguarding the security of supply in the Netherlands and large parts of Germany since 2009: • Management, maintenance and expansion of the transmission grid • Promoting integration of the European electricity market • Linking up offshore wind parks to the German grid 1) 220/380 kV grid 1998 2008 2009 2010 Electricity Act: TenneT acquires Dutch national electricity grid (220/380 kV) TenneT acquires Dutch national electricity grid (110/150 kV) E.ON Netz1) changes its name to transpower. TenneT acquires transpower and becomes first cross-border grid operator transpower becomes TenneT TSO 2000 E.ON Netz established
