When you designed your contract option types, you were already considering the possible contract option event types. You will need to define a different contract option event type for each different type of event that may occur for the same contract option type.

Your next step is to determine whether or not characteristic values will be needed for each contract option event of this type. The characteristic values are available for use by the algorithms, when processing the contract option events. On the contract option event type, you must define the possible characteristic types for contract option events of this type. You may also define a default value, if applicable.

For our example, we will define two types of interruptions, which may be applicable for customers on the same rate. We will define only one type of curtailment event. None of the event types require characteristic values.
