  1. DevelopmentStrategies in ‘Round One’ Stuart Hall, natural power BWEA – UK Offshore Wind 2003

  2. Natural Power Experience • Case studies- Solway offshore (~180MW) • - Codling offshore (660MW+) • - Lillgrund offshore (120MW) - Crystal Rig (63MW) - Bowbeat (31MW) - Deucheran Hill (16MW) • Services- Resource / Energy assessment programmes • - Windfarm design • - Development management incl. EIA, permits, PPAs • - Construction management • - Operations management • ~345MW consented, ~800MW in planning, ~2,000MW in design Development Strategies in 'Round One'

  3. Development Problems • Options • Preferences • Pressures • Competing interests • Inexperience • Uncertainty • Risk Development Strategies in 'Round One'

  4. The Solution 1/4 • Decide on a clear management strategy… • In-house Management • External Management. Both choices require experience, competence and time/resource • Define a development strategy… • Higher exposure / lower risk / quicker build - carry out detailed surveys to allow quick construction before permits awarded, or • Lower exposure / higher risk / slower build - carry out only limit surveys before permits awarded. Development Strategies in 'Round One'

  5. The Solution 2/4 • Define permitting path - Legal advice - T&WA, CPA, FEPA, EA S36&S37, Private Bill, T&CPA, - Cable crossing railways, flood defences, roads. • Define the project… • Physical & economical constraints, - Lease area, depth, ecology, infrastructure, other users, grid, sensitive views, WTG size, economics indices… • Project scale, - Following constraints and scoping consultations  Development Strategies in 'Round One'

  6. Solway Constraints Development Strategies in 'Round One'

  7. The Solution 3/4 • Define a design philosophy… • Must be clear, understandable and communicable, i.e. Rigid grid, randomised, emblemic • Royal Fine Arts Commission (of Scotland) (design consultee) • Competently led and managed (design pressures ) Development Strategies in 'Round One'

  8. Wind engineering - Seeks  yield & capacity Civil engineering - Seeks cheap & simple construction Financial -  return and  risk. Economic? Financable? O&M - Easy access, reliable technology Manufacturer -  Separation dist, standard WTG Consultees -  impacts,  benefits Example Design Pressures • Permitting - Seeks an easy life ( impacts,  benefits) Development Strategies in 'Round One'

  9. Will raise sea levels and increase flooding Reduce on-shore windspeeds Sailing will be impossible because of distorted winds Always on the best fishery The Solution 4/4, finally • Communicate, consult & optimise design • The permitting process • Misconceptions: Development Strategies in 'Round One'

  10. UK further offshore Layout: 450m x 600m 220 WTG 160m to tip 3 to ~5.5MW ea Codling Bank Issues… I.e. wake predictions Development Strategies in 'Round One'
