Scenario objectives
• Support the SBA Energy by developing services providing irradiance data among other parameters
• Simulating the case of the sitting of a solar power plant.

From the user’s point of viewStep Description
Step 0 The investor asks a consulting company for a study for a given geographical area
Step 1 The consulting company wants to obtain the necessary information and puts requests to the GEOSS portal
Step 2 The specific application is invoked
Step 3 The specific application invokes various web services and resources to retrieve needed information. It then invokes the specific processing web services.
Step 4 The specific application packs the layers as an archive file and deliver it to the consulting company
Step 5 The consulting company retrieves the archive, performs the study by exploiting the retrieved information and its own models and reports to the investor
Step 6 The investor takes a decision

Meteorological data
• Map of annual irradiation on a plane always facing the sun (kWh/m²)– Source from SoDa service 5km resolution– Results from specific processing (computing time from few minutes to few hours)
DNI (Direct Normal Irradiance) DNI + shaded DEM

Geographical data• Source from SRTM DEM, results from specific processing. 100 meters resolution
Ratio between actual daylengthwith shadows and astronomical daylength (%)
Altitude in meters
Local maximum slope in degree

Geographical data: Hydrology and usage
• Security cooling device for Solar Plants– Need an important flow of cooling water
(typically 2 m3/s for a 12 MW Solar Plants)– Estimated cost for the linking to the Hydraulic Network Maps depends on
the linking length (typically 300 k€/km)– Need Hydraulic Network Maps
(Map scale better than 1/200 000)
Hydraulic network. Scale 1/200 000 Sample of estimated cost of hydro network linking in Keuros

Geographical data: Electricity network and usage
• Linking to High Voltage Electric Network– Estimated cost for the linking to the HV Electric Network Maps depends on
the linking length (typically 200 k€/km)– Need High Voltage Electric Network Maps
(Map scale better than 1/200 000)
Estimated cost of electric network linking KeurosElectric network. Scale 1/200 000

Environmental data
• Protected area & risk and hazard– Cope with regulation– Adequacy between the solar plant lifecycle and ROI
Protected area. Scale 1/200 000 Risk and Hazard. Scale 1/200 000
