To make the energy transition a success, AI is a great contributor throughout the energy value chain, from production to consumption! While a big number of wind, solar and biomass RE projects are emerging, it becomes critical to analyse and measure the operation of these installations in order to improve their operating performance, detect anomalies, anticipate maintenance and provide recommandations to field operators.
