Consortium Investors

• E.On Renewables is one of the UKs leading wind
  farm owner-operator-developers
• Shell WindEnergy is the one of the top ten
  largest windfarm asset owners in the world and is
  actively expanding its windfarm business across
  Europe and the USA
• CORE is a joint venture between Farm Energy (the
  originator of the project) and ENERGI E2 of
  Copenhagen (owner of 460MW windpower incl. Nysted
  Offshore Wind Farm).

Key Consenting Issues

• Open, sensitive and innovative approach essential
  to ensure success
• Red throated diver
• English Nature
• JNCC (Joint Nature Conservation Committee)
• RSPB (Royal Society for Protection of Birds)
• Fisheries
• Fisheries committees
• Fishing communities
• Shell fisheries
• Navigation/Radar
• PLA (Port of London Authority)
• MCA (Maritime and Coastguard Agency)
• Trinity House
• Cable Landfall/Onshore Sub-station
• Graveney with Goodnestone Parish Council

Red Throated Diver

• Displacement Will the birds habituate to the
  windfarm structures and if not, what ecological
  impact arises?
• Collision not the issue

9
Red Throated Diver
GB population estimate 4,850 Based on aerial
surveys JNCC now estimate 11,000 Red-Throated
Divers in Greater Thames Estuary Constructive
dialogue with English Nature and RSPB

Onshore Sub-station at Cleve Hill

• Visual impact minimised
• Cut into hill
• Masked by bunding and planting
• Connects to National Grid at
  400kV
• No new towers or lines

Summary

• Up to now we have avoided unreasonable demands
  regarding f.ex. Burial depth, burial method,
  restricted size of turbines, construction
  methods.
• This has been achieved by a close collaboration
  between planning and engineering teams to find
  solutions that are environmental, technical and
  economically viable
• Unfortunately we have not been able to get a
  agreement regarding grid connection and therefore
  the project is going to halt now and wait until
  2012 before it can go live.
• Hopefully the wind turbine prices have fallen to
  a more reasonable level at that time
