Outage map guide
- The outage map is updated every five minutes, providing a snapshot of service interruptions in TEP’s service area.
- A red box represents the approximate area of an outage. Because outages affect distribution circuits that do not neatly conform to geographic areas, some or even most of the addresses displayed within the box may have active electric service.
- The map displays outages that have been confirmed by TEP crews as well as some outages that are under investigation based on reports from customers or system control equipment. For safety and privacy reasons, outages affecting fewer than 25 customers will not appear on the map.
- Estimated restoration times are determined once the cause of an outage has been identified.
- Please be aware that updates to the map may be delayed during periods of heavy storm activity and multiple simultaneous service interruptions.
Definition of terms:
The time an outage is first reported to TEP.
Power outages are organized into four stages:
- Gathering Outage Information — In this early stage, TEP is receiving early outage reports from customers while employees are conducting an initial evaluation of the outage.
- Crew Dispatched to Scene — TEP employees are on the way to the affected area.
- Crew on Scene — TEP employees are in the affected area to address public safety issues, assess equipment damage and take initial steps toward restoring service to customers.
- Restoration/Repair Under Way — TEP employees are actively working to restore service and repair or replace equipment.
Customers Out of Service
The current number of customers without power. This number will change over time.
The number of customers whose electric service has been restored since the outage began. This number will change over time.
Estimated Time of Restoration
An estimated time and date when TEP expects service to be restored to all affected customers.
- Pending Investigation — Employees have not yet arrived on scene to determine a cause.
- Investigating — Employees are on scene and attempting to determine a cause.
- Equipment Damage — Examples include outages caused by vegetation making contact with electrical equipment or when equipment is found damaged but an exact cause cannot be determined.
- Equipment Damage - by Weather — Examples include outages caused by debris blown into lines during storm, wind damage and lightning strikes.
- Equipment Damage - by Vehicle — Examples include outages caused by automobiles that crash into power poles and construction vehicles that damage underground cable.
- Poles/Wires Down — Any situation where power poles or power lines are on the ground, presenting a potential public safety concern.
- Equipment Repair/Replacement — An example would be equipment failure during a high usage period
- Emergency/Public Safety Issue — Examples would include service interruptions that occur when firefighters are responding to a structure fire or utility crews are responding to a natural gas leak.
