6. Final Remarks

Why offshore wind and why floating offshore wind?

Why Offshore Wind?

• Higher wind resource and less turbulence

• Large ocean areas available

• Best spots in wind onshore are becoming scarce

• Offshore wind, including deep offshore, has the capacity to deliver high quantities of energyenergy

Why Floating Offshore Wind?

• Limited spots with shallow waters (mostly in the North Sea)

• Most of the resource is in deep waters

• Huge scale ocean areas available

• Less restrictions for offshore deployments and reduced visual impacts

• Enormous potential around the world: PT, Spain, UK, France, Norway, Italy, USA, Canada …


Deep offshore wind provides a significant growth opportunity in the long term

Test period: at least 12 months

Phase 2 - Pre-commercialCapacity: 15 - 25MW – 3 to 5 WindFloat units

Location: TBD, grid connected

Location: TBD, same as Phase 2

Turbine: TBD, same as Phase 2


The Windfloat Project - Phase 1 Project Schedule

Project Schedule

� Pre-FEED stage was concluded by December 2009

� The FEED phase was initiated and is expected to be concluded by July 2010

� Several decision points through out the project giving EDP total control over the project

� Every decision/contract shall be approved by EDP


Why do it in Aguçadoura?

Advantages of the Aguçadoura scenario:

Besides the pre-engineering of the Windfloat, the main outcome of Pre-FEED stage was the selection of Aguçadoura as the

preferred site for the deployment of the project (compared to, for example, testing in the Algarve)

Advantages of the Aguçadoura scenario:

� Allows the utilization of a more appropriate and representative turbine

� Platform is significantly closer to the market, allowing a faster development towards a (pre-)commercial phase

� Site has more representative sea and wind state conditions;

� Takes advantage of the clean power produced (physically and also financially);

� Provides for more relevant and effective testing as well as utilization of more in depth offshore skills;

� Promotional value for the country and project developers is much stronger

� If the project is successful a leadership claim in the deepwater offshore space is not questionable;

� Provides a direct comparison with the Hywind project in Norway (similar power ratings).

6. Final Remarks

Economics and Cost Reduction Potential – short term

Phase 1 costs breakdown

24

The Windfloat Platform

• The WindFloat platform is the main driver of the total cost

• Main drivers for cost reduction:

- Construction of the WindFloat platform

- WindFloat design and Fabrication tooling

- Alltogheter assuming a reduction of less than 10% in the platform cost

• Current development path should allow a competitive cost/MWh in commercial phase


Cost Reduction Potential – Future Vision

Future Cost Reduction Potential

• Using cheaper materials

- Cost reduction (rough estimate):

· Using 10% of other materials (concrete, composites, etc) in the platform allows decrease of at least 6% in its cost

· Corresponding to at least 3% in total cost of the project

• Increase the Power of the turbine

- The size of the platform is driven by the metocean conditions - No - The size of the platform is driven by the metocean conditions - No significant impact in the size of the platform

- Turbines of 7 MW – 15 MW in development

- Cost reduction (rough estimate):

· 37% in the WindFloat platform(1) per MW

· 13% in total cost of the project per MW

• Improve the installation procedure and O&M strategy

25

(1) Assuming that the platform will increase 25% in material to double the size of the turbine

Agenda


6. Final Remarks

• EDP believes that Offshore Energy, together with other emergingrenewables, will be an important growth vector for the company in thefuture

•Resource and a favourable surrounding context positions well Portugal in a race for leadership in the offshore energy sector

Final Remarks

Technology Development28

•EDP believes that the WindFloat project is presently one of the mostinteresting innovation projects being developed in Portugal and that it hasthe potential to become one of the key technologies in floating offshore wind

•Sinergies between wave energy and deep offshore wind, namelyinfrastructure, should be explored in articulation, fostering the creation of anocean energy cluster in Portugal
