California avoids blackouts amid heat wave

California avoids blackouts amid heat wave


For nearly three hours Tuesday night, California officials warned of imminent power outages as the state’s power grid struggled to keep up with high demand during the heat wave.

The Golden State avoided blackouts, although three Northern California cities experienced brief power losses.

8 p.m., California Independent System Operator reduced its level 3 notificationthe last step before calling for a blackout, saying that “consumer conservation played a major role in protecting the reliability of the electrical grid.”

There were “no night loads,” the grid operator said; however, officials in Alameda, Palo Alto and Healdsburg said they implemented “circuit breakers” for a short period of time.

In Alameda, municipal officials said at 6:20 p.m. that transmission problems were starting. Power would be out for two circuits in an hour, according to Alameda Municipal Power.

Shortly before 7:30 p.m., utility officials in the Bay Area city said a second hour of power outages had been called off.

“There are no further outages tonight,” the agency said in a tweet. “Crews are working to restore power to all customers in the first hour of the outage.”

City officials in Healdsburg confirmed the power outage around 6:30 p.m

“As directed by CAISO, the power outage began,” according to Facebook post by the city of Sonoma County.

Outages of about an hour per zone could wrap around every block until the power shortage ends, city officials said.

“Due to the reduced load on the system, the need for outages has ended,” city officials said at 8:10 p.m.

Palo Alto officials said around 7 p.m. that they had been authorized to restore power to about 1,700 customers after the outage to meet Cal ISO’s “load shedding requirements.”

“We did not order the circuit breaker,” Anne Gonzales, an ISO spokeswoman, said in an email to The Times Tuesday night. “We held on [Energy Emergency Alert] 3 without cargo cargo, and [the alert] ended at 8 pm”

Gonzales did not respond to several telephone requests for comment.

Shortly after 7 pm, Cal ISO Rating that peak demand on the national grid had reached 52,061 megawatts, “a new all-time record.”

The alert did not affect customers of the Los Angeles Department of Water and Power, as the utility operates its own grid and is separate from Cal ISO.

“We do not suspect the power outage is due to a power shortage and is not part of a power outage. [Cal ISO] has planned,” said Mia Rose Wong, spokesperson for the municipal corporation.

The DWP forecast for Tuesday demand will be elevated but not enough to exceed the available power generation capacity and reserve capacity, Wong said.

However, the agency advised its customers to conserve energy and follow the grid regulator’s guidance, including setting thermostats to at least 78 degrees and not using large appliances.

In addition to encouraging its customers to reduce energy use, the DWP makes extra power available to Cal ISO when available, Wong said, although it was unclear if there was any extra power Tuesday night.

A heat wave is now expected to last through Friday, but the worst could be over for the southern half of the state — even as temperatures remain dangerously high.

For most of Northern California, heat was expected to peak on Tuesdaybut temperatures are forecast to remain above average for the week, according to the National Weather Service.

As of Tuesday afternoon, the weather service confirmed that the city of Sacramento had set an all-time temperature record. The previous high of 115 degrees broke the previous record of 114 degrees set on July 17, 1925, meteorologists said. About an hour later, officials reported that the temperature had risen to 116.

The state capital has seen a string of extreme weather over the past year, Daniel Swain, a climate scientist at UCLA and California climate fellow at the Nature Conservancy, said. in a tweet Tuesday evening.

“First its longest summer on record, which ended with its wettest day on record, followed by its worst start to a calendar year on record, now followed by its hottest day on record,” Swain wrote.

In Hanford, the weather service office said that as of 3 p.m., “all major weather reporting stations in the San Joaquin Valley set daily temperatures.”

Four cities in the Bay Area broke records for the highest temperatures recorded for any day of the year, according to the weather service.

San Jose’s temperature of 109 on Tuesday surpassed the previous high of 108, set on September 1, 2017.

Santa Rosa’s high of 115 broke the high of 113 set in 1913; Napa’s 114 broke the record of 113 sets in 1961; and King City in Monterey County hit 116, breaking the 2017 record of 115 sets.

Redwood City in San Mateo County hit 110, tying the record set in 1972.

Livermore led Tuesday with 116, tying the record set a day earlier. The highest temperature ever recorded in Livermore was 115, set on September 3, 1950.

In the video was posted on Twitter on TuesdayGov. Gavin Newsom called the heat across California unprecedented, and warned that the state is headed for worse.

“The risk of outages is real, and it’s imminent,” Newsom said. “These triple-digit temperatures across much of the state are driving, not surprisingly, record demands on the power grid.”

He said the heat wave “is on track to be the hottest and longest on record” for California and parts of the West for September.

The West has long had extreme heat events, but studies have shown that human-caused climate change is making these heat waves longer, more frequent and more intense.

warm tips

Stay informed

You can track the forecast for your area by going to the National Weather Service website and search by city, state or ZIP Code for the latest weather updates and notification. Follow your local officials and agents on social media for tips and information about resources available in your area. Put it hot list to make sure you are prepared.

Stay indoors and wear light clothing

Officials from the National Weather Service and public health offices are advising people to stay indoors as much as possible, especially between 10 am and 3 pm, when the sun is strongest. If you exercise outside, it is recommended to do it early in the morning or in the evening.

If you don’t have air conditioning, the Centers for Disease Control and Prevention recommend go to the mall or the public library. You can also refer to your county’s website or call your local health department for more information cooling centers in your area. Other options include taking cold showers twice a day or even searching a shady yard or garden. (Health officials at UCLA say electric fans will not prevent heat-related illness when temperatures reach 90 degrees and above.)

Beware of heat-related illnesses

According to the CDC, heat-related illnesses can range from heat rash and sunburn to more serious conditions, including heat exhaustion and heat stroke, and are caused by the body’s inability to cool itself by sweating. Signs of heat stroke, the worst of the heat-related illnesses, include a temperature of 103 degrees or higher; hot, red, dry or moist skin; quick, strong pulse; headache; dizziness; nausea; confusion and loss of consciousness. If you are experiencing these symptoms, seek immediate medical attention. CDC advice against drink anything and recommends moving to a cool place and in a cold bath or using a cold cloth.

Signs of heat exhaustion include profuse sweating; cold, pale and clammy skin; fast, weak pulse; nausea or vomiting; muscle mass; fatigue; dizziness; headache and despair. If you show these symptoms, get out of the sun immediately, find a cool place or cool towels and drink water. Monitor your symptoms and get help if you vomit, if symptoms worsen or if they last more than an hour.

Stay hydrated

Drink plenty of water, especially before going out, is important in preventing heat-related illnesses. UCLA officials warn against wait until you are thirsty to drink. During extreme heat, it is better to drink at least two to four cups of water per hour. (For those who work abroad, The CDC recommends one cup of water, or 8 ounces, every 15 to 20 minutes.) Health officials also advice against drinking alcohol during extreme heat, as it causes dehydration and increases the risk of heat-related illnesses.

It is important too to replenish the salt and minerals your body loses when you sweat by drinking low-sugar fruit juices or sports drinks. Dietitians too recommend eat foods rich in water – think watermelon, celery and cucumbers – as well as drink adequate fluids.

Symptoms of Dehydration in adults includes severe thirst; fatigue; dizziness; lightness; dry mouth and/or lips, and frequent urination. In infants or young children, look for dry lips and tongue; no tears when crying; no wet diaper for more than three hours; sunken eyes and cheeks; a soft sunken spot on the top of their head, with itching or numbness.

(If your doctor eats certain foods, or controls how much water you drink, ask about what steps should you take during a heat wave to stay properly hydrated.)

Look at the most vulnerable

In addition to keeping yourself safe and healthy, regularly interact with those who are at high risk, including the elderly, children, pregnant women, the homeless, those who work outside and those without air conditioning. Heat it also affects your pets, so keep them indoors, or if they’re going to be outdoors, make sure they have plenty of water and a shaded area. Never leave a child or pet in the back seat of a car, as the temperature inside the car can rise very quickly, even with the windows cracked.

To help the homeless, the Los Angeles County Department of Public Health recommends donating water, electrolyte packs, light and loose clothing, tents, towels and other supplies. to local organizations.
