2. Objectives – Renewable Energy CP Support GEOSS outcomes related to application of EO data for renewable energies. Relevant areas are: –Siting –Design –Yield estimation and resource monitoring –Forecasting –Integration –Operation –Trading –Environmental monitoring Renewable energy community: users of the energy, suppliers of systems and components, electricity transmission and distributions operators, heat distributors providers of services, value adders, market players

3. Societal Benefit Why Renewable Energy Now? World-wide interdependence of conventional energy production Energies and uses of energies have a dramatic impact on global warning, human health and sustainable economic development Technologies mature and in development Huge potential in both developed and developing countries Dramatic benefit in improved siting, operating monitoring, etc. using long-term historic data and nowcasting Improved forecasting crucial to integration into electricity grids and for utility and power plant operations

4. 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, snow cover, vegetation status –Ocean parameters –Infrastructure compatibility –Environmental impacts

5. Gaps identified by Users Several projects as e.g. ESA EOMD projects ENVISOLAR, EO-WINDFARM and EO-HYDRO have shown shortcomings: –data are hard or costly to access –form difficult to interpret –quality information unknown –user involvement in product definition is missing –delays in data access –handling of large data amounts –NRT chains of data supply are not reliable enough –spatial and temporal coverage not optimized for energy needs –standardisation not sufficient –different data sources difficult to handle –lack in long-term funding of EO providers, project-based data –long-term archives not funded

Digital elevation models are needed for wind, solar, hydro, biomass. Temperature is needed for solar and biomass Irradiance is needed for solar and biomass Aerosols are needed for solar and biomass …. Interaction between Renewables
