Storm Management supports two operational modes: Non-storm Mode and Storm Mode. Non-storm mode applies to everyday operations. When calculating estimates, crew resources are not taken into account because it is assumed there are enough crews available to handle all events. Storm mode is useful during and after a storm or other high volume outage periods. In this mode, the estimate calculations factor in crew availability. All control zone views operate in non-storm mode until explicitly placed into storm mode.

While it is periodically simulating the entire restoration process, Storm Management calculates an estimated assessment and restoration time for each eligible event. These estimates for each event are accessible to other modules (for example, may be displayed in a Work Agenda column). However, it is not always prudent to have these estimates available to the other modules; for example, when you initially enter storm mode and the available crew resources have not been fully defined, the calculated estimates would be rather inaccurate.

ERT Overrides provides the ability to override calculated ERTs for one or more specified control zones. The ERT overrides will impact existing outages as well as future outages in those control zones until the override is removed. Either a new specific ERT can be specified using the ERT Override tab, or an ERT offset from the outage start time can be specified using the ERT Delay tab. Both tabs also support tiering, which provides more granular override values based on the number of customers impacted by an event.
