‘ Pelamis ’ - Wave Energy in Action !! 2

Wave Hub - What is it? Simple idea! § An area of sea with an electrical cable and connection point offshore into which arrays of Wave Energy Converters will be connected § A connection to the National Grid for initially up to 30 MW of wave power § Permits to allow connection and operation of the facility 3

Why are we doing it? § Demonstrate commercial viability of wave energy 4

Wave Hub … a route to commercialisation R&D NaREC Demonstration Initial prototype Refined prototype EMEC Pre- commercial device Wave Hub Market entry with commercial product Market penetration 5

What do we hope will happen? § Demonstrate commercial viability of wave energy § Maintain and strengthen the UK lead in marine renewable energy § Develop a new industry in the South West § Contribute significantly to the South West renewable energy generation 6

Where did it come from? § 2001 SWRDA Regional Renewable Energy Strategy § 2002 Agreement to support biomass, wave and tidal power § 2002 Set up Regen SW § Oct 2003 Seapower South West Report § Jan 2004 METOC Seapower SW Review § April 2004 Wave Hub Feasibility Study Starts 7

Feasibility Study Organisation Advisory Group SWRDA Regen SW Mr Dominic Vincent – Environment Manager PROJECT MANAGER SCOTT WILSON OCEANS Dr Mike Patching BOND PEARCE CSEP D CLARK AD LITTLE HALCROW 'Technical Feasibility 'Consents and 'Stakeholder ' Business Case' 'Publicity' Study' Permits' Consultation' 8

Project Requirements (What do we need to do?) § A site (offshore and onshore) § A suitable resource (wave energy) § A grid connection § Feasible technology (practical and cost effective) § A business case (market need and financially viable) § Legally allowed to do it (permits and consents including an EIA) § Stakeholder support 9

Potential Benefits The potential to create an International industry in SW § Development of wave energy sector and associated supply chains – including marine technology and advanced engineering resulting in over 450 jobs in the SW by 2010 and 700 by 2020. § Inward Investment – GVA from indirect impacts to the SW of £15million and £27 million respectively with 20-40% expected in Cornwall. § 20MW wave power produced and sold by 2008 – supplying 14,000 homes; meet up to 30% of Cornwall ’ s renewable energy target and up to 5% of the Regional target. § Links to Higher Education – Centres of Excellence in CUC, Plymouth and Exeter leading to the establishment of a high profile wave energy R&D base in west Cornwall. 22

Wave Hub – a long way to go! Major issues to be addressed: § Funding § Consents and Licenses § Stakeholder Agreement § The Wave Device Developers § Engineering Studies and Surveys § Detailed Design § Procurement § Construction § Operation 23

Permits & Consents § Electricity Act 1989 Section 36 (DTI) § Food & Environment Protection Act 1985 (DEFRA) § Coast Protection Act 1949 § Town & Country Planning Act 1990 § Electricity Act 2004 § The Marine Bill ? § European Legislation - EIA Directive § Nature Conservation Directives § SEA § Crown Estate § ING 24

Contracts § Power Purchase Agreement (PPA) § Device Developer Agreement(s) § Engineering Procurement and Construction (EPC) § Grid Connection Agreement § Management, Operation and Maintenance Agreement § Metering Agreement § Company Formation 25

Costs Wave Hub Development and Construction Estimated Costs Stage 95% probability of Mean probability 5% probability of being being exceeded exceeded £1.42 million Development £1.25 million £1.60 million £12.42 million Construction £11.41 million £13.45 million 26
