Value of lost load

The CDF relates the magnitude of customer losses (per kW interrupted) for a given duration of a power outage.

While the general shapes of all three curves are similar, the magnitude of loss varies dramatically depending on the customer's size.

The CDF predicts the loss per interrupted kW based on factors that influence the outage.

The CDF is usually calculated based on defined market segments such as residential, commercial, and industrial.

However, in a large area it is a normal practice that the interruption cost is aggregated to represent a general picture of the load losses.
