With triple-digit temperatures forecast to last until Thursday throughout Southern California, the California Independent System Operator is emphasizing energy conservation, issuing an alert for transmission and generator operators to cancel any maintenance work so all resources are available during the heat.

The scorching temperatures triggered an excessive heat warning from the National Weather Service. The peak of the heat will be Wednesday and Thursday, with Friday bringing only a few degrees of relief.

Southern California Edison (SCE) is also asking customers to conserve energy during this latest heat wave.

“We have called a Save Power Day for Wednesday,” said Mark Wallenrod, SCE director of Program Operations. “This program helps enrolled customers to earn bill credits while they conserve energy during periods of high demand for electricity.”

A Save Power Day will take place Wednesday from 2-6 p.m. Customers who have signed up for the program will be receiving notices the day before the event.

Customers can earn up to $100 in bill credits through this program. To sign up for the Save Power Days program, visit: sce.com/spd. Customers can select how they would like to be notified, either by phone, email or text.

The National Weather Service’s excessive heat warning starts at 11 a.m. Tuesday and ends at 8 p.m. on Thursday. Temperatures could reach as high as 105 degrees throughout the valleys of Los Angeles and Ventura counties.

SCE reminds its customers to stay as cool and safe as possible during these excessive heat days and offers these tips:

  • Set thermostats no lower than 78 degrees.
  • Close drapes and blinds to keep out direct sunlight during hot periods.
  • Use electric fans instead of air conditioning when practical.
  • Reduce electricity use between noon-6 p.m. — peak hours of energy use.
  • Shut off lights when leaving a room.
  • Limit how often you open your refrigerator door.
  • Avoid air-conditioner use when evaporative coolers or humidifiers are running.
  • When possible, businesses should shift power-intensive work processes to morning or evening hours.
