Power was unexpectedly cut by San Diego Gas & Electric on Sunday, leaving about 115,000 customers without electricity on a day that saw record-breaking hot temperatures.
The outage occurred due to a failed generator, the San Diego Union-Tribune reports. SDG&E said the California Independent Systems Operator ordered them to drop 150 megawatts of load in their service territory immediately around 1:15 p.m to avoid overloading the system.
Customers reported that their frustration with the unplanned outage was exacerbated by the lack of information SDG&E provided.
The company’s website also experienced technical difficulties during the outages.
Temperatures on Sunday were recorded as high as 96 at Montgomery Field, breaking the previous record of 87, NBC 7 reports.
