As we enter the sixth day of the heat wave, roughly 1,400 people are in the dark early Thursday morning due to power outages.
SoCal Edison crews are working to restore power to approximately 1,000 customers in Compton.
"When we have high temperatures, the grid ... it does put some stress on our electrical grid. Just like how a car can overheat in hot weather, the same goes for our electrical equipment," said Sally Jeun with SoCal Edison.
The biggest problem Wednesday was in Boyle Heights, where DWP outages have been intermittent for two days.
John Peralta was eating at a seafood restaurant in the neighborhood when the power cut out. He spoke to our media partner NBC 4.
"TV and fans all went out," he said. "And signals are out here, almost crashing outside."
By 5 a.m. this morning, DWP had restored power to Boyle Heights. The heat wave is expected to last through the weekend, and experts say we may get another one next week.
