Grid data transparency

Overview of the status and impact of the innovation

Innovation 2


Rapid digital transformation over the past decade has led the grid to become highly interconnected and automated. It generates vast amounts of data from customers’ meters, from measurements on the grid, from other grid assets and from markets of immense value to multiple stakeholders. These data should be made as transparent as possible, using communication frameworks and data management infrastructure to support the collection, exchange, use and security of the information.


Transparency of data and digital communication is essential to the power system planning needed for large-scale EV adoption. Data are vital for making optimal decisions on charging infrastructure locations, charging times and duration, grid services and participation in local flexibility markets, among other matters.

The ELIA platform shares data on the status of the grid as well as qualitative data, including issues and reports. Users can download data to improve operations. For example, data on grid imbalances enable entities active in the system to co-operate to avoid grid problems. ELIA is also creating an advanced platform that includes historical load data on EVs and wind power, which will also help solve grid-related problems (Elia Group, 2022). Similar platforms are also being developed by Energienet in Denmark and TenneT in the Netherlands.
