LF Energy Summit Europe 2026

Last year, the LF Energy project OpenSynth expanded with the launch of D-GITT, an open data hub featuring RTE7K: a dataset of the whole French transmission grid, including topological changes over three years. Striking the interest of other actors in opening their own dataset, RTE7K demonstrated its values as a realistic, open benchmark for grid analysis.

Now, RTE, CRESYM, eRoots and IRT SystemX joined forces to launch the RTE7K Challenges, a series of challenges centered around the dataset. The first one, kicking off at this summit, focuses on tackling the "missing piece" for running powerflows on the RTE7K dataset: power injection data. Participants are tasked with producing realistic, synthetic injections using whatever public data and methodology they can come up with. As well as being an enticing challenge for participants, the outcome will be a critical extension to RTE7K that will enable further users to test and validate tools using data comparable to what was previously exclusive to TSOs.

Future challenges will explore topics like AI-driven grid topology management, power flow analysis and more, pushing the boundaries of what’s possible with open grid data.
