GEOSS AIP-5 Architecture Implementation Pilot, Phase 5 - Energy Scenario- Lionel Ménard MINES ParisTech Lucien WaldMINES 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 m Yearly 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: 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

Irradiation maps 2/3 Overview of the solar processing (downscaling + calibration) Downscaling GHI map Irradiation components on tilted plane (Ruiz-Arias et al. 2011) Downscaling GHI map Irradiation components on tilted plane (Ruiz-Arias et al. 2011) Local horizon computation Calibration with 20 ground stations of Météo-France and 3 dedicated ground stations (RSP * ) Raw HC-3 Downscaled and calibrated HC-3 Downscaled and calibrated HC-3 * RSP: rotating shadowed pyranometer SRTM: 100 m DEM

Issues tackled with a high resolution atlases Targeted users: Policy planners, consulting companies 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.
