How we restore power after the storm.
As soon as it's safe to begin working, our crews start turning the lights back on for our customers. Restoration efforts proceed in an orderly manner. Scouts begin with assessment, then crews start at the source and work outward.
Scouting and Damage Assessment
Right after the storm passes, Entergy personnel must assess damage to electric equipment and facilities to determine corrective actions. Finding out how hard the system was hit must be carried out quickly and accurately after the storm is gone. Damage assessment scouts are prepared in advance, and immediately after impact, they are dispatched to begin the assessment.
Backbone feeders, those with major trunk lines that support large electrical loads to customers, get particular attention. They must be restored to service as soon as possible. This initial assessment helps develop an estimate of crews required, resources needed and the time estimated to complete restoration.
Following this, scouts are assigned to work directly with storm teams in the field to help provide the detailed assessment and support needed to facilitate the restoration. Depending on the severity of the damage, full assessment can take up to three days.
What is the scouting process?

Starting At The Source
When crews build their restoration plans, they start at the source. If power can't make it from the generating plant to your local substation, it can't be delivered to your neighborhood or your street.
FIRST, power plants, the primary sources of power production, are restored. THEN, large transmission lines are repaired and restored. These high-voltage lines, which are often strung on high steel towers, deliver power to cities, towns, and major industrial facilities. NEXT, substations are brought online. Local substations must be functioning in order for energy to reach the power lines on your street.
How We Restore Power
Once power is flowing back into an area via these larger systems, restorations occur in this order:
- Emergency services, life support facilities and communications networks (police, hospital, fire stations, media, industry) are restored.
- Lines serving large blocks of customers are restored next.
- Lines serving neighborhoods follow because multiple customers are involved.
- Individual services are then restored because fewer customers are involved, and, in the case of scattered outages, it often takes more time and effort to get power back on.
Certain types of work, such as repairs requiring the use of bucket trucks, cannot be safely completed when winds exceed 30 miles per hour.
