How Power is Restored

Step 1 - Transmission towers and lines supply power to one or more transmission substations. These lines seldom fall, but they can be damaged by a hurricane or tornado. Tens of thousands of people could be served by one high-voltage transmission line, so if there is damage here it gets attention first.

Step 2 - We have several distribution substations, each serving thousands of member-owners. When a major outage occurs, the local distribution substations are checked first. A problem here could be caused by failure in the transmission system supplying the substation. If the problem can be corrected at the substation level, power may be restored to a large number of people.

Step 3 - Main distribution supply lines are checked next if the problem cannot be isolated at the substation. These supply lines carry electricity away from the substation to a group of member-owners, such as a town or housing development. When power is restored at this stage, all member-owenrs served by this supply line could see the lights come on, as long as there is no problem farther down the line.

Step 4 - The final supply lines, called taps, carry power to the utility poles or underground transformers outside houses or other buildings. Line crews fix the remaining outages based on restoring the greatest number of member-owners.

Step 5 - Sometimes, damage will occur on the service line between your house and the transformer on the nearby pole. This can explain why you have no power when your neighbor does. Your co-op needs to know you have an outage here, so a service crew can repair it.
