Identifying old and obsolete wind turbines for repowering

Case overview

As a leading renewable energy developer, our client sought to integrate GIS and climate modeling capabilities to precisely identify wind turbines for repowering in Germany.

Genesis Ray meticulously gathered data on renewable energy infrastructure nationwide, expertly mapping assets within a customized GIS application. This solution seamlessly integrated project-specific details such as technical specifications, ownership, OEM information, and precise location data for individual wind assets, including their connectivity to substations and the grid. Our GIS interface presented this comprehensive data through user-friendly widgets and features, enabling detailed analyses.

In collaboration with our climate modeling experts, we mapped wind speeds across Germany, providing Typical Meteorological Year profiles at P10, P50, and P90, leveraging data from ERA5 and DWD. Additionally, our app incorporated site-specific attributes such as contour lines, slope, flood risk, soil bearing capacity, and land cover, alongside exclusion zones like military areas, airports, protected zones, and residential areas.

Moreover, we developed Environmental Impact Layers, specifically Bird Sensitivity Mapping, identifying critically endangered bird species based on collision data from wind turbines in Germany. This holistic approach ensures informed decision-making and efficient strategies for repowering wind turbines.

Our Approach

  • Data Compilation: Genesis Ray undertook an extensive data collection effort, focusing on the renewable energy infrastructure across Germany. We developed a custom GIS application to map renewable energy assets, incorporating detailed project-specific data such as technical specifications, ownership, Original Equipment Manufacturer (OEM) information, and the precise locations of wind assets, including substations and grid connections.

  • GIS Application Development: The customized GIS platform featured intuitive widgets and tools for easy access and analysis of the compiled data, enabling stakeholders to conduct thorough evaluations of potential repowering sites.

  • Climate Modeling Collaboration: Our team, in partnership with climate modeling specialists, executed a detailed mapping of wind speeds throughout Germany. We provided Typical Meteorological Year (TMY) profiles at different probability levels (P10, P50, P90) using data from ERA5 and DWD. The application also integrated site-specific factors such as topography, flood risks, soil capacity, and land usage, in addition to identifying exclusion areas like military bases, airports, protected lands, and residential zones.

  • Environmental Impact Analysis: A key feature of our solution was the Environment Impact Layers, which included Bird Sensitivity Mapping. This component identified areas with critically endangered bird species that are at risk of colliding with wind turbines, utilizing collision data to inform safer repowering strategies.
