As San Diego’s power grid works to keep up with the demand from the record-breaking temperatures , tens of thousands of people across the county were without power Sunday and into Monday.
A San Diego Gas and Electric (SDG&E) spokesperson told FOX 5/KUSI Sunday afternoon they believe the heat is related to the mass power outages across the county, however they are still investigating the cause.
The spokesperson also took the chance to thank their customers for being patient and said SDG&E crews are working around the clock in the heat to bring back power to all those impacted.
As of 5 p.m. Sunday, the SDG&E outage map reported about 6,000 households were without power. As of 10 p.m., over 9,000 households were without power as SDG&E crews continue to work to get that power back on. The communities of Old Town/ Mission Hills/ Hillcrest, and Paradise Hills/ Skyline/ Bay Terraces had the most outages reported at that time, with over 1,000 outages in each area.
At one point Sunday, more than 10,000 people were without power in the Jamacha area, according to SDG&E.
In total, around 13,000 were without power across San Diego County at its peak.
By Monday at 6 a.m., only a handful of outages remained. The most widespread outage reported by SDG&E was about 852 customers in the area of Valley Center, Rincon and Pauma Valley. According to the utility’s outage map, crews are still assessing the cause of the disruption.
As of Monday afternoon, there are still nearly 1,000 without power across the county.
On Monday, the heat will once again accompany severe weather with a chance of storms in San Diego’s mountain areas.
