  4. Vattenfall Key facts • Owned by the Swedish State • Business • Electricity: generation, transmission, distribution and sales • Heat: production, distribution and sales • Gas: distribution and sales • Consulting and contracting activities in the energy sector • Market • Sweden, Denmark and Finland • Germany, the Netherlands and Belgium • The United Kingdom • Wind power is a cornerstone of Vattenfall’s action on climate change 4 | A Greener Economy | Göran Loman | 2011.02.23

  5. Vattenfall in the UK • Acquired 90MW Kentish Flats through Elsam merger in 2005 • Acquired AMEC Wind Energy in November 2008 • Acquired Thanet Offshore Wind Energy in November 2008 • Acquired Eclipse Energy in November 2008 • Merger with Nuon in July 2009 5 | A Greener Economy | Göran Loman | 2011.02.23 5
