Abstract: An alerting method implemented by an electronic supervision device connected to an energy production device. In the method, a determination, by a deviation cause classification model taking as input a history of deviations between a value representative of a prediction of an amount of energy produced by the energy production device and a value representative of an amount of energy actually produced by the energy production device, of an occurrence of a failure in at least one component of the energy production device. An alert is generated according to which at least one component of the energy production device is defective.

Abstract: A method for monitoring the energy of an equipment. The method includes: obtaining a first energy prediction model and an energy measurement frequency; predicting energy, via the prediction model, using, as input for the model, the result of a first energy measurement and contextual data of the equipment during and/or since the first measurement, the prediction being carried out before and/or during a second measurement subsequent to the first measurement and carried out with the obtained measurement frequency with respect to the first measurement; and varying the measurement frequency for a third subsequent energy measurement, as a function of a difference between the predicted energy and the second measurement. A method for building the first energy prediction model, corresponding electronic devices, system, computer program products and recording medium.
