Energy SBA Scenario Description

Thierry Ranchin, Mines ParisTech, France

GEOSS AIP-2 Kickoff

25-26 September 2008

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

Answer

Process

2. Meteorological, geographic and environmental data layers needed

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

Input parameters & output result• Inputs:

– bounding box (lat., lon.), dates, scale, optional layers, valid email address

• Output results: – the geo-referenced layers (GeoTIFF, shape files) should be provided as a downloadable archive
