Wave Hub - What is it?

Simple idea!

§ An area of sea with an electrical cable and connection point

• ffshore into which arrays of Wave Energy Converters will

be connected § A connection to the National Grid for initially up to 30 MW

• f wave power

§ Permits to allow connection and operation of the facility

4

Why are we doing it?

§ Demonstrate commercial viability of wave energy

5

R&D Initial prototype Refined prototype Pre- commercial device Market entry with commercial product Market penetration Demonstration

Wave Hub … a route to commercialisation

6

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

7

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

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

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.

23

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

24

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

25

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

Conclusions

§ It is Technically Feasible !! § It is wanted and supported by Industry and Government § It is supported by SWRDA § It appears to have positive environmental benefits and negligible negative impacts (to be confirmed by EIA) § It has Local Stakeholder support (so far) § It is legal § It requires a lot more work! § It will cost - but not excessively so! § We are not alone!
