Stage 3 Emergencies (from SDG&E)
Due to a shortage of electricity throughout the state, the Cal-ISO, may require that SDG&E interrupt service to some of our customers. If this happens, we'll do our best to notify customers in advance, however because of the emergency nature of the situation, there may not be time.
If there are Stage 3 required outages, they will be rotated through various areas of the county to minimize the time any single area is without power. It is expected that an area could be without power for between one to four hours.
SDG&E will work with the local media to alert you to the situation and the potential for these types of outages. And as always it is best to be prepared with the supplies mentioned below.
Outage Preparedness: The following are some suggested supplies to have on hand in case of an outage or other emergency:
- Battery-powered emergency lighting (or flashlights, at a minimum);
- A portable or battery-powered radio;
- A wind-up or battery-powered clock;
- Nonperishable foods and water (including a manual can opener);
- First aid kit; and
- A telephone that does not depend on electricity.
Protecting Your Equipment
It is your responsibility to protect your equipment from power outages and fluctuations. You should protect highly sensitive equipment by installing sensors designed to shut off the power supply if extreme power fluctuations occur.
Unprotected equipment should be unplugged, or the circuit breaker shut-off until the power is restored. We suggest leaving one light on, so you will know when power has been restored.
Once the power has been restored for about ten minutes, equipment should be brought back on-line in stages. Energizing one breaker or fuse (or large piece of equipment) at a time and ensuring the equipment is functioning properly before moving to the next breaker or fuse provides additional protection for your equipment. In addition, waiting ten minutes before resetting the breakers or fuses will help eliminate problems that can occur if equipment is brought back on-line before SDG&E’s system is stabilized.
If the doors are kept closed on refrigeration equipment, the contents can be maintained for several hours. Dry ice can be used to protect the contents during extremely long outages. Use gloves when handling dry ice, and use caution not to place it directly on the contents.
