At EDF, the Island Energy System Department provides, manages and monitors the public service of electricity in the most remote French territories. Despite the very difficult conditions after the catastrophic hurricanes IRMA and MARIA, EDF teams put all their efforts in reestablishing electricity in islands such as Saint-Martin and Saint-Barthelemy. Thanks to Tableau, the team was able to visualize the areas where electricity was available and map the areas where it was reestablished. Today, EDF is also providing thanks to Tableau Mobile the monitoring of its clients consumption deep in the Amazonian jungle, in five villages within the High Maroni. With Data Viz, EDF can analyse, visualise and better manage its operational activities to provide the best customer service around several continents.
