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
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
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
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
Energy systems Life Cycle / Data Needs

Data Requirements depend on the phase
Data Issues:
• error bar (DA, risk) even
for individual values
• certification, bankable
• benchmark
• availability, backup systems
• automatic monitoring

Interaction between Renewables
• Snow information is needed for hydropower and solar.
• Mesoscale modelling is needed for wind, solar,
biomass and hydropower.
• Wave information is needed for ocean and wind energy.
• 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
