Both the Imperial Irrigation District and Southern California Edison battled power outages on Monday evening, as the sun set on a day with record-breaking hot temperatures.

As of 8 p.m., there were about 60 IID customers in La Quinta and 10 in Indio without power.

But IID had restored power to about 763 homes in and around La Quinta's PGA West and to customers in Coachella, near Frederick Street and Avenue 54, according to the utility.

In Southern California Edison territory, 73 homes in Palm Springs lost power around 4 p.m. The utility estimated that it could restore power to those customers by 2 a.m. Tuesday.

About 70 Palm Springs customers have been without power since 6 p.m. Sunday, with an estimated restoration time of 2 a.m. Tuesday.

A 186-home outage in Palm Desert began around 6 p.m. and SCE said power would likely be restored by 1:30 a.m.

And 44 homes in the Cahuilla Hills area of south Palm Desert lost power around 11 a.m., with an estimated restoration time more than 12 hours later, at 2 a.m. Tuesday. SCE blamed the outage on an equipment failure.

Cooling centers are open across the Coachella Valley during daytime hours, but most close by 5 p.m. The Palm Desert Community Center remains open until 9 p.m. on weekdays.

The California Independent System Operator, which operates most of the state's high-voltage grid, called for a Flex Alert for an 11-hour period on Monday. During Flex Alert times, the ISO asks residents to limit their electricity usage as much as possible to help avoid outages.

Monday's Flex Alert period ran from 10 p.m. to 9 p.m. It was the first such alert since July 1, 2015, when officials called for power savings over a seven-hour stretch.

To save power, the ISO recommends keeping air conditioning at 78 degrees Fahrenheit or warmer and avoiding the use of big appliances like washing machines and dishwashers.

This story will be updated if more outages are reported or if power is restored.
