Technical Challenges A Developers Perspective Ocean Energy Forum 4 - PowerPoint PPT Presentation

Technical Challenges A Developers Perspective Ocean Energy Forum 4 th April 2014

About  DP Energy encompasses a number of Development Companies under a DP Group Structure.  A Private Company - Self Funded and o wned and controlled by Maureen and Simon De Pietro.  Utility scale but only renewable energy - wind, marine and solar.  Operating in UK & Ireland, Canada, and Australia.  Owner & Operator as well as just Project Developer.

DP Marine Energy  Commercial Project Developer NOT a Technology Developer  Project Comes First Philosophy  Technology Neutral but focussed on Open Rotor Horizontal Axis  Bringing Wind Development Experience into Marine  Primarily Tidal for now but with an interest in Wave  330MW of Tidal Projects under development

Tidal Portfolio Name MW Status Capacity AfL – Sept 2011 30MW West Islay Tidal Energy Park Application for 30MWconsent lodged September 2013 (future potential of West of Islay Scotland 400MW) AfL – October 2012 100MW Fair Head Tidal Energy Park Baseline birds and mammals survey underway. Application for first 10MW Off Antrim Coast Northern Ireland consent planned end 2014, remaining 90MW 2015. FP7 Tides project with Siemens MCT/DEME and 4 Academic Partners 200MW Original SSE AfL 2009 Westray South Major surveys complete. Application for first 60MW consent planned end Pentland Firth and Orkney Waters 2014, remaining 140MW 2018+ Scotland

Developer Role  Site & Resource Due Diligence Package  Licences and Permits  Grid Connection Agreement  Site design and technology application  Lease  Feed in Tariff - PPA  TSA and W, O&M  Balance of Plant Warranties  Insurance  SPV Partnering Investors and Funding

Technical Challenges  Turbine Performance, Reliability & Availability o Warranties & Guarantees o Bankable Standards - IEC  Array marshalling & power conditioning infrastructure o Collection voltage and dry or wet export options o Wet mate connector solutions o Cable Armouring or Protection?  Foundation and installation methodology o Promising developments but no agreed cost effective solution

Technical Challenges  Yield analysis and yield/turbulence uncertainty o Wind & tidal current effects o Multiple rotor wake effects - arrays o Bankable Standards - IEC  Metocean wave issues Hs & Hmax o Fatigue – blades / powertrain / structure o Accessibility – Installation & O&M

Making it happen…  Increased EU/member state support for early arrays  State Aid Guidelines need to support funding strategies  De-risked Commercial Scale Projects – longer term signals for investors  Infrastructure Support – need for grid funding in key resource areas  Environmental Aid Guidelines (EAG) - Streamline consenting procedures
