Improve materials, components and power take-off equipment(failures to date are related to components and not the basicconce t

Main supporting policies

Policy Background-

Action plan to meet the major energy challenges Europe faces:

By 2020 renewable energy should account for 20% of the EU's countries

National Energy Policy CommitmentPortugal (highly dependent on imported oil and gas) has stepped up

.particularly in wind power and, more recently, in solar energy, while attempting to diversify its RES including waves

NATIONAL RENEWABLE ENERGY ACTION PLANStrategic actions: diversification of RES, stimulating R&D of newtechnologies - Comprehensive policy mix exists which include waves

Portuguese Policy Stated Objecives

Creation of an industrial cluster associated with wave power

No significant offshore engineering & operation capacities

Adjacent industries exist but are not prepared for specific needs

O&M issues will be the most vital competition factors in the early phase, andPortugal has a good chance to position itself

, -

must be accessible and benefit entire sector

Attract demonstration & industrial develo ment to Portu al

Due to substantial fundin a for first full-scale devices 5-15M/MW

We must try to avoid being a mere turnkey consumer like in other sectors

the cost-efficiency of future deployment sites will be decisive.

Major cost factor: offshore operations and related (cost) uncertainty for

Project Developers, Investors, and Operators benefit from open test site

Th hTh h


29/34

The reasons why areThe reasons why are

Portugal energy dependence is above 80%

WE can supply a share of electricity demand of: 1% (2020) and 10-15%

in 2030 with cumulative savings of 1-2 B in fossil fuel imports by 2030.

WE can avoid 30 MtCO2 to 2030 (corresponding to cumulativesavings of 0,6-1,5 B)

Renewable Energy Association (APREN) proposal for the Portuguese National Plan




30/34


WE will require and cumulative investment in Portugal of around 4-

6B by 2030 to achieve an installed capacity of 3GW

WE would can create around 2.000 direct obs b 2020 and

between 7.000-11.000 by 2030.

WE can be competitive with coal and gas between 2020-2035

without accountin for externalities and ositivemacroeconomic impacts.

Conclusions

Some Final RemarksSome Final Remarks


33/34

Some Final RemarksSome Final Remarks

Significant progress in the last 5 years, in spite of small investment done( 300M /10 years)

Development of WE is taking longer, and being harder and more expensivethan anticipated, with technology possible stabilizing in 2015

Wave ener is a LONG-TERM investment!!

- (Developers can concentrate on demonstrate and further develop technology)

EU MS targets for OE are very ambitious
