Most industrial plants are open to perturbations and interruptions in their operations caused by lightning strikes. In the majority of cases this is due to lightning striking electricity cables, which has a negative effect on energy supply. Industrial plants need to be kept operational and, therefore, face the problem of deciding when to transfer to back-up energy supplies and for how long.  In many cases, the decision is made by simply deciding whether the sky looks threatening with storm clouds. Manually changing energy supplies can be hazardous and is not really conducive to a policy of sustainable development, particularly if petrol driven electric generators are used. Furthermore, if the transfer is made too late, production can be slowed down or even stopped. The subsequent financial losses could be critical. Each year, insurance companies in France report numerous cases of production lost in this manner, with financial costs running to millions of Euros.
