GEOSS AIP-5Architecture Implementation Pilot, Phase 5 - Energy Scenario-
Lionel Ménard MINES ParisTech
Lucien Wald MINES ParisTech
Supported by the FP7 ENDORSE project
Kick-off Meeting May 2012
The proposed Energy scenario:
“Generation of local atlases for decision-support in solar energy policy
planning and private investment ”
Introduction– PACA (Provence Alpes Côte d’Azur) is the sunniest
region of France– Bounding box: c. 300 km x 250 km– Mountainous zones (in particular the East part of PACA)
SRTM Digital Elevation Model ranging from -15 m to 4000 mYearly Global Irradiation on Horizontal Plane (GHI) for 2010
Scenario’s expected innovations
• Deals with the refinement in scale which will be suitable for local decisions.
• Combine irradiance and other meteorological data with data of various natures that intervene in decision-making process.
• Allow the user to get the necessary data in one request and not multiple as currently
Irradiation maps 1/3
• Source: MACC product (HelioClim-3)– Spatial resolution: c. 4 km– Temporal resolution: 15 min– Time coverage: 2004-2010
• Irradiation maps:– Mean of monthly and yearly sums of irradiations– The direct (beam), diffuse and global components– Orientation: horizontal, normal incidence and a set of pre-computed plane
“standard” orientations
• Need of improvements:– Spatial resolution improvement on PACA to account for high resolution
effects of orography (optical path variation, shadows and sky-view fraction effects)
– Validation and uncertainty analysis of the resulting monthly sums of irradiations with pyranometric ground stations

Slide 9 – March 2010
• Improve accuracy from existing databases to assess the potential of solar energy in a focused area of interest (improvement range from 3 km to 200 m)
• Relate this information to other types of geographical information, e.g., physical and administrative
• Provide computer-aided method for decision making, (eg. desktop or Web based GIS applications)
• Provide recent information, of known quality and uncertainty, spanning over several years and easily accessible
• Develop a replicable and scientifically-validated methods for creation of such atlases within the ENDORSE project.
