Ocean Energy Forum 4th April 2014

Technical Challenges A Developers Perspective

 DP Energy encompasses a number of

Development Companies under a DP Group Structure.

 A Private Company - Self Funded and

• 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.

About

 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

DP Marine Energy

Tidal Portfolio

Name MW Capacity Status

West Islay Tidal Energy Park

West of Islay Scotland 30MW AfL – Sept 2011 Application for 30MWconsent lodged September 2013 (future potential of 400MW)

Fair Head Tidal Energy Park

Off Antrim Coast Northern Ireland 100MW AfL – October 2012 Baseline birds and mammals survey

• underway. Application for first 10MW

consent planned end 2014, remaining 90MW 2015. FP7 Tides project with Siemens MCT/DEME and 4 Academic Partners

Westray South

Pentland Firth and Orkney Waters Scotland 200MW Original SSE AfL 2009 Major surveys complete. Application for first 60MW consent planned end 2014, remaining 140MW 2018+

 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

Developer Role

 Turbine Performance, Reliability & Availability

• Warranties & Guarantees
• Bankable Standards - IEC

 Array marshalling & power conditioning infrastructure

• Collection voltage and dry or wet export options
• Wet mate connector solutions
• Cable Armouring or Protection?

 Foundation and installation methodology

• Promising developments but no agreed cost effective

solution

Technical Challenges

 Yield analysis and yield/turbulence uncertainty

• Wind & tidal current effects
• Multiple rotor wake effects - arrays
• Bankable Standards - IEC

 Metocean wave issues Hs & Hmax

• Fatigue – blades / powertrain / structure
• Accessibility – Installation & O&M

Technical Challenges

 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

Making it happen…

Tidal Power Challenging but almost there
