# loss of load probability (smart grid) (LOLP)

The term Loss of Load Probability (LOLP) is used in power transmission networks and stands for the probability that there is a loss of load.

In the case of a Loss of Load Probability, the demand for electrical energy exceeds the energy capacities of the energy network at a given time. Not as much energy can be supplied via the grid as is required. The period in which the energy shortage takes place is given in days per year and shows in the diagram the differences compared to previous years.
