Starting Wednesday, Southern California is about to get a lot hotter.

The National Weather Service has issued a hazardous weather outlook alert for Los Angeles and Ventura counties and the Antelope Valley. Temperatures could reach as high as 107 degrees and the downtown L.A. area will be in the 90s.

With several days of high temperatures in the forecast and an expected increase in energy demand, Southern California Edison (SCE) has called a Save Power Day for Wednesday and Thursday. Customers who have signed up for the program will be receiving notices the day before the event.

“Customers who take part in the Save Power Day program can help conserve energy for everyone and earn some bill credits too,” said Mark Wallenrod, SCE director of Program Operations.

When a Save Power Day is called, customers can earn up to $100 in bill credits per year for conserving energy between 2-6 p.m. To sign up for the Save Power Day program, go to: sce.com/spd. Customers can select how they would like to be notified, either by phone, email or text.

On the days designated Save Power Days, customers enrolled in the program will receive a message the day before. Customers earn $0.75 per kilowatt-hour reduced between 2-6 p.m. In order to participate in this program, customers must be enrolled for event notifications.

The National Weather Service is forecasting high temperatures in the Southland to last through Friday. SCE reminds customers to stay as cool and safe as possible and to avoid heat-related injuries during excessive heat days.

Here are a few tips to conserve energy and stay cool:

  • 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.
