SDG&E sees record power demand amid ongoing heat wave

SAN DIEGO (FOX 5/KUSI) — The heat wave scorching Southern California will continue through Monday night and the power grid has been working hard to keep up.

The demand from the high temperatures all weekend hit its peak Sunday evening and caused an energy demand not seen in the region since 2014, San Diego Gas and Electric (SDG&E) said on Monday.

The National Weather Service (NWS) reports the record-breaking high temperatures will continue through Monday night for all areas of San Diego County. But the good news is some reprieve from the heat is coming later this week.

While San Diego’s coastal areas are under heat advisories through 8 p.m. Monday — San Diego, Oceanside, Vista, Chula Vista, Carlsbad, Encinitas and National City. NWS says high temperatures are expected in the uppers 80s and low 90s near the coast, and 90s to 100 degrees just a few miles inland.

SDG&E has confirmed the demand during the record-breaking heat wave contributed to the mass amounts of power outages on Sunday.

If your power goes out during an extreme heat event, there are several steps you can take to stay cool.

According to the CDC, residents can dress in lightweight clothing, use battery-powered fans to cool your home, stay hydrated, reduce activity, take cool showers, keep refrigerator and freezer doors closed to preserve food, close blinds and curtains to help keep out the sun, along with finding alternative ways to prepare food like grilling outside.
