Power Outages in La Jolla

A portion of La Jolla continues to experience power outages due to extreme heat and high energy demand. Our crews are working to reconfigure the circuit in the area and restore power as quickly and as safely as possible. The circuit reconfiguration could potentially take a few days, and some customers may continue to experience outages on and off in the coming days. As a temporary solution, our crews are working overnight to set up a backup generator.

Customers in the area are encouraged to continue conserving power to reduce stress on the circuit, in particular limiting the use of air conditioning and pool pumps, charging electric vehicles from 6 a.m. – 4 p.m., and avoiding charging their energy storage battery systems. 

We appreciate our customers patience and apologize for any inconveniences the outages have caused over the holiday weekend.

State grid operator asks all Californians to conserve energy to help prevent power outages

SAN DIEGO, August 31, 2022 – In response to a voluntary Flex Alert issued for Wednesday, Aug. 31, through Thursday, Sep. 1, by the state grid operator due to high temperatures, San Diego Gas & Electric (SDG&E) is urging customers to visit its website to learn about simple actions they can take to reduce their energy use while still staying cool.

SDG&E’s one-stop-resource, sdge.com/myenergy,  features a series of tried-and-true tips that can make an immediate difference. Energy conservation is particularly important during the peak hours of 4 p.m. to 9 p.m. when the grid is typically under the most stress due to waning solar energy and rising energy demand.

No-Cost Energy Savings Tips

  • Pre-Cool Your Home. Take advantage of lower priced energy by using your A/C to cool your home before 4 p.m. During on-peak hours of 4 p.m. to 9 p.m., adjust your thermostat higher, health permitting.
  • Cool Down with a Fan. Use ceiling and/or tabletop fans to cool off and leave the thermostat at a higher temperature, health permitting. Turn off fans when you leave a room as fans cool people, not rooms.
  • Block the Sun. During the hottest part of the day, cover windows to block the sun’s heat. If you can, open windows at night and early mornings to let the cool air in.
  • Use Small Appliances. Instead of the oven, use small appliances such as a microwave, toaster oven or slow cooker. They use less energy and won’t add much heat to your home.
  • Power Down. Switch off your electronic devices, such as computers and coffee pots, when not in use. Keep in mind, electronics in standby mode still draw power. Use a power strip to power down devices and appliances at one time. 
  • Shifting use. Shift some energy use – such as running a dishwasher or clothes washer – outside the on-peak hours of 4 p.m. to 9 p.m., when demand on the electric grid is typically highest and the cost of electricity is the highest.
