Vladimir Alexiev presents the Transparency Energy KG (TEKG) project, which converts the ENTSO-E electricity market transparency data to a semantic KG and complements with external data sources (VIES for VAT validation, OpenStreetMap for power plant maps and coordinates, several power plant databases for correspondences/coreferencing).
We have implemented a number of advanced validations over fundamental electricity data such as the EIC file (Energy Identification Code), power plant data, and specific market data. KGs afford a holistic view over the data that allow us to uncover a number of data problems, presented in a Data Quality Assessment Dashboard. This could help ENTSO-E and national electricity authorities (Transmission System Operators, TSO) diagnose data quality problems and improve data collection procedures and legislation.
