A production forecast for the next 30 minute period is made using the additional instrumentation on site.

The system used allows the sky to be observed from the plant’s site using a camera pointing upwards that takes hemispherical photos. Used in conjunction with image processing algorithms, a cloud mass movement forecast and physical models, the state of the cloud cover is forecast for the very short term (up to 30 mins) along with the plant’s production.

This offer is adapted in particular to insular networks and hybrid systems. It favours real time management and decision making in order to optimise the alternative energy production methods to implement.
