5. Centrica’s Current Portfolio • Onshore • Glens of Foudland 26MW • Braes of Doune 72MW • (50% JV – Airtricity) • Offshore • Round 1 • Barrow Offshore Wind 90MW • (50% JV - DONG Energy) • Lynn 90MW • Inner Dowsing 90MW • Round 2 • Lincs 250MW • Docking Shoal 540MW • Race Bank 620MW • Total 1,778MW Braes of Doune

6. Lynn & Inner Dowsing Facts and Figures • Two 97.2 MW wind farms • Two 90 MW grid connections • Total of 54 x 3.6MW turbines • Rotor diameter 107 metres • Generation equivalent to annual demand of 130,000 homes • Managed on a multi-contract basis • First power May 2008

7. Addressing Environmental Challenges Marine environment is busy, supporting wildlife, industry (aggregate extraction, commercial fishing) and recreation It also provides us with a number of services including coastal defence, food sources and nutrient recycling Developing offshore wind farms in balance with the existing environment is achieved through developing under a robust consenting process Environmental Impact Assessment, mitigation and monitoring Working with our stakeholders and with other developers to find solutions to generic problems

8. Consenting Process Project Definition & scoping Public & stakeholder consultation Data collection, analysis & assessment Production of Environmental Statement (ES) Public & stakeholder consultation Submission to Department for Energy and Climate Change (DECC) for consent under Electricity Act, Coast Protection Act (CPA) & Food & Environmental Protection Act (FEPA) Consent granted, usually with a number of licence conditions including mitigation and monitoring Note, above is set to change with Planning Act and Marine Bill and the creation of the Independent Planning Committee (IPC)

9. Environmental Impact Assessment Better understanding the environment through the collection of high quality data over a number of years on the physical, biological and human environment Undertaking transparent assessments to meet or exceed ‘best practice’ Work closely with stakeholders to ensure that we are meeting their requirements Work with other developers and stakeholders to identify solutions to common problems e.g. FLOWW - commercial fisheries Liaison group NOREL - shipping and navigation liaison group COWRIE – environmental liaison group funding research to benefit the industry

10. Environmental surveys Surveys include: • Coastal processes • Geology • Birds and marine mammals • Shipping and navigation • Electromagnetic interference • Socio-economics • Visual seascape assessment • Hydrology and marine water quality • Fish and seabed communities • Underwater noise and vibration • Commercial fishing • Archaeology and cultural heritage • Safety

11. Key Challenges - Consents & Environment Bird Monitoring for LID - Construction & Post Construction • Radar surveys (& proposed aerial surveys)

12. An we do things better? There is always room for improvement: Better scoping – making use of the data becoming available from operating wind farms to target real issues at the earliest opportunity Better communication – working more closely with our stakeholders to identify solutions and build bridges on a project by project level and nationally through liaison groups An industry approach – continuing to work within the industry to meet generic issues
