Objectives – Wind Energy CP
• Support GEOSS outcomes related to application of EO data toward valuable wind energy results:– Siting– Design– Forecasting– Integration– Operation
• Wind energy community: users of the energy, suppliers of systems and components, electricity transmission and distributions operators, providers of services, market players
Societal Benefit
Why Wind Energy Now? • Mature technology• Wind is fastest growing source of energy
in the world today• Huge potential in both developed and
developing countries• Dramatic benefit in improved siting,
energy varies with cube of wind speed• Improved forecasting crucial to utility
integration and operations
Justification
Requires interdisciplinary knowledge and disparate information that go beyond existing collaborative activities:– Weather data archives for site modeling– Weather forecasting in all timeframes– Boundary layer meteorology– Climate analysis and long-term variability– Extreme event analysis and temporal change– Turbulence information– GIS, land use data, surface roughness data, orography– Ocean parameters– Infrastructure compatibility– Environmental impacts
Earth Observation for Wind
Advantages Limitations• Wide area observations
(e.g. met mast gives only point data, can there be a better site nearby?)
• Ability to monitor remote places in a non-intrusive & objective manner
• Uniform in space, consistent in time, cost-effective
• Ability to go back in time (e.g. existence of archive to detect changes, trend). Ideal for decisions regarding long-term investment such as wind farms.
• Indirect measure - need ground truth (i.e. less accurate than in-situ)
• Limited sampling (space, time, holes, clouds)
• Availability (e.g. SAR?)
• Need value-adding to turn data into information
Offshore Wind Energy
Active remote sensing for resource assessment
Scatterometer• Coarse Resolution (O(25)km)• Good temporal frequency• Long-term archive • BUT does not work close to coast where wind farms are built
Synthetic Aperture Radar• High Resolution (O(150)m) • BUT Low temporal revisit• Archive (mainly ERS, ENVISAT, RADARSAT)
Need to combine EO sources BUT better used to get the spatial variability rather than magnitude

What is the availability of wind farms? Can I send a vessel to repair? What kind of vessels? Should I invest in maintenance or more turbines?

Wind rose retrieved through numerical model of boundary layer
Integration with ancillary data Sources into user software
Adding to the Value Chain
Aim to make the end-to-end EO value chain more effective by:
• Delivering information services
• Organising the supply (e.g. developing infrastructure and standards)
• Federating the demand (e.g. user-pull, not technology pushed)

Services Resource Assessment:
• Nowcast - NRT monitoring
• Hindcast - archive
• Forecast - modelling
Services Environmental Impact
Data Issues:
• Error bar (DA, risk)
• Certification
• Benchmark
Data Requirements depend on the phase
Wind energy can be the model for a broader Renewable Energy Community for GEOSS

Structure of WE CP
• Steering Committee with worldwide representation– End users– Experts– Participants from the national or international
programs– Participants from space agencies– Policy makers/analysts
• Core Working Groups – Experts– Members of the Community of Practices
Activities
• Development of core working groups• Workshops for users• Standardisation (Metadata, protocols,
architecture, databases, information…)• Building networks and develop incubation
projects• Coordination of users requirements across
energy societal area and societal benefits areas
• Favouring business development• Disseminating and educating GEOSS
potential and best practices
Products and Schedule for 2006-2007
• Approval of TOR and CP (Dec 2005)• Initiate user survey (Feb 2006)• Workshops (TBD in 2006, 2007)• Draft report and recommendations (July 2006)• Report to User Interface Committee (Nov 2006)• Initiate Incubation projects through virtual
centers (early 2007)• Coordinate developing of networks of Databases
and Information (2007)• Outreach activities (2006 -2007)
