REDataNet – Building a Coordinated Network and Digital Infrastructure for Standardized and Interoperable Data on Renewable Energy Plants and Their Environmental Contexts

The rapid expansion of renewable energy requires reliable, transparent, and interoperable data on energy plants and their environmental contexts. Although detailed location and technical data on renewable energy installations are collected by numerous actors in research, administration, and industry, these efforts remain largely fragmented. Data are processed independently, using heterogeneous formats and standards, with limited transparency regarding data provenance and updates. This leads to duplication of work, inconsistent results, and inefficient use of resources, while hindering evidence-based decision-making in energy planning, environmental assessment, and policy design.
REDataNet addresses these challenges by building a coordinated network of stakeholders and developing a shared digital infrastructure for renewable energy plant data in Germany. The project brings together research institutions, public authorities, and other key actors to formalize collaboration along the entire data processing chain – from data collection and cleaning to enrichment, documentation, and dissemination. Through a moderated network process, REDataNet systematically identifies existing data sources, workflows, overlaps, and stakeholder needs, thereby laying the foundation for more efficient and transparent data practices.

A central goal of the project is the development of a common semantic metadata standard tailored to renewable energy plants and their environmental attributes. This standard builds on existing approaches and ontologies, extends them where necessary, and ensures interoperability across datasets and disciplines. By explicitly documenting data provenance, processing steps, and updates, the standard supports FAIR data principles and enables reproducible research and long-term reuse.

The technical core of REDataNet is the implementation of a Renewable Energy Data Platform integrated into the established EE-Monitor website. The platform links registries, repositories, and data services, and provides tools for automated data collection, comparison, validation, and collaborative enrichment. Tutorials and user-oriented documentation ensure that the infrastructure is accessible to a broad community.

Through targeted outreach and continuous network expansion, REDataNet promotes adoption of the developed standards and services beyond the project duration. By reducing redundancy, improving data quality, and strengthening collaboration, REDataNet enhances the efficiency of renewable energy research and supports informed decisions for a sustainable, nature-compatible energy transition.
