Heat wave tests Southern California’s power grid amid gas shortage

Thermometer sign reads 118 degrees, heat

LOS ANGELES (Reuters) – California’s power grid operators warned homes and businesses on Monday to conserve electricity as rising demand for air conditioning stoked by a record-setting heat wave across the U.S. Southwest tested the region’s generating capacity.

The so-called Flex Alert was posted until 9 p.m. Pacific time during a second day of triple-digit temperatures that strained Southern California’s energy production, creating a potential for rolling blackouts on the first official day of summer.

But the peak hour for energy demand came and went Monday evening without disruption of the region’s power delivery network, the California Independent System Operator (ISO) reported.

“Since we’re past that and have not experienced any trouble, I think we’re headed into the safe zone,” agency spokeswoman Anne Gonzales told Reuters.

Temperatures were expected to begin abating on Tuesday, according to weather forecasts. As of Monday night, there were no plans to extend the Flex Alert, ISO officials said.

Monday’s alert was the first big test of power generators’ ability to meet heightened energy demands in the greater Los Angeles area without natural gas supplies normally furnished by the now-crippled Aliso Canyon gas storage field, effectively idled since a major well rupture there last fall.

The oven-like heat prompted the city of Los Angeles to keep its network of public “cooling centers” – libraries, recreation centers and senior centers – open for extended hours as a haven for people whose homes lack air conditioning.

Area home improvement and hardware merchants were doing a brisk business in fans and AC window units.

Brett Lopes, 31, a freelance lighting technician, stopped in a Home Depot outlet near downtown to buy supplies for a homemade air conditioner he called a “swamp cooler” to use while he waited for his landlord to repair his broken AC unit.

“It’s brutal,” he said of the heat, explaining that he looked up directions on YouTube for assembling the makeshift cooling device. “It doesn’t work as well as AC, but it’s better than sitting in 100 degrees.”

Others flocked to public swimming pools.

“It was really refreshing today, but more crowded than usual,” said Paul Stephens, 31, a pastor who was swimming laps at the Rose Bowl Aquatic Center in Pasadena, where the mercury climbed to 108 Fahrenheit (42 Celsius) .

BALANCING THE GRID

The ISO, which runs the state’s power grid, urged consumers on Monday to cut back on electricity usage, especially during late-afternoon hours.

Utility customers were advised to turn off unnecessary lights, set air conditioners to 78 degrees Fahrenheit or higher, and wait until after 9 p.m. to run major appliances, such as clothes washers and dryers.

Gonzales credited public cooperation with the flex alert for likely helping avert widespread outages on Monday.

Large stretches of three states sweltered in a second straight day of record, triple-digit temperatures, as the National Weather Service posted excessive-heat warnings through Wednesday for southern portions of California, Arizona and Nevada, though the hot spell appeared to have peaked on Monday.

Power customers ranging from homes and hospitals to oil refineries and airports are at risk of losing energy at some point this summer because a majority of electric-generating stations in California use gas as their primary fuel.

Since the energy crisis of 2000-2001, the ISO has imposed brief, rotating outages in 2004, 2005, 2010 and 2015, mostly related to unexpected transmission line or power plant failures during periods of unusually high demand.

With California’s largest natural gas storage field shut down indefinitely at Aliso Canyon, state regulators have warned that Los Angeles faces up to 14 days of gas shortages severe enough to trigger blackouts this summer.

Aliso Canyon, owned by Southern California Gas Co, a division of San Diego-based utility giant Sempra Energy, normally supplies the region’s 17 gas-fired power plants, hospitals, refineries and other key parts of California’s economy, including 21 million residents.

The gas leak there, ranking as the worst-ever accidental methane release in the United States, forced thousands of nearby residents from their homes for several months after it was detected last October. The leak was finally plugged in February.

Venezuela Makes Fridays Holiday to Ease Energy Crisis

CARACAS (Reuters) – Venezuela’s President Nicolas Maduro has decreed that all Fridays for the next two months will be holidays, in a bid to save energy in the blackout-hit OPEC country.

“We’ll have long weekends,” Maduro said in an hours-long appearance on state television on Wednesday night, announcing the measure as part of a 60-day plan to fight a power crunch.

A severe drought, coupled with what critics say is a lack of investment and maintenance in energy infrastructure, has hit the South American nation, which depends on hydropower for 60 percent of its electricity.

Venezuela’s opposition slammed the new four-day work week as reckless in the face of a bitter recession, shortages of foods and medicines, and triple-digit inflation.

The measure comes on the heels of Maduro decreeing a week-long break over Easter, ordering some shopping malls to generate their own power, and shortening daily working hours.

“For Maduro the best way to resolve this crisis is to reduce the country’s productivity,” said Caracas city councillor Jesus Armas. “Fridays are free bread and circus.”

Some Venezuelans took to social media to express their surprise. “You must be kidding???,” one Twitter user said. Many others wondered how the measure would impact schools, bureaucratic procedures and supermarkets.

It was not immediately clear how the non-working Fridays would affect the public and private sector.

The 60-day plan’s fine print will be announced on Thursday, said Maduro during the television program, which included music, dancing and giant pictures of late leader Hugo Chavez.

“I think we can overcome this situation without increasing fares or rationing,” added Maduro.

Hackers Access Power Grid, N.Y. Dam; Might Have Accessed Government Talks

Hackers gained access to the United States power grid, including detailed drawings that could have been used to cut power to millions of people, according to a new Associated Press report.

The report, published Monday, indicated that there have been roughly 12 times in the past 10 years when foreign hackers accessed the networks controlling lights across the United States.

That includes one instance where hackers, believed to be from Iran, had swiped passwords and detailed sketches of dozens of power plants, invaluable tools if one planned to cut off the power. Cybersecurity experts told the Associated Press the breach (which affected energy company Calpine, which operates 83 power plants) dates to at least August 2013 and could be ongoing.

The Associated Press reported that hackers accessed passwords that could have been used to access Calpine’s networks remotely, along with highly detailed drawings of 71 energy-related facilities across the country. That could allow skilled hackers to specifically target certain plants.

But targeting a plant and successfully shutting off the power are two different things.

The Associated Press report noted the power grid is designed to keep the lights on when utility lines or equipment fail. To cause a widespread blackout, a hacker would have to be exceptionally skilled, bypassing not only a company’s security measures but also creating specialized code that disrupts the interactions of the company’s equipment. Still, experts told the AP that it remains possible for a sufficiently skilled and motivated hacker to send a large swath of the country into blackout, and enough intrusions have occurred that a foreign hacker can likely “strike at will.”

The Associated Press report was published the same day the Wall Street Journal unveiled that Iranian hackers accessed the controls of a dam about 20 miles away from New York City in 2013.

In another breach, tech company Juniper Networks announced last Thursday that it discovered some “unauthorized code” in its software that could have allowed skilled hackers to improperly access some devices and decrypt secure communications. CNN reported the FBI is investigating the hack because it fears the code might have been used to spy on government correspondence.

Because government use of Juniper products is so widespread, one U.S. official told CNN the hack was like “stealing a master key to get into any government building.” CNN reported a foreign government is believed to be behind the hack, but it still is not clear who is responsible.

Juniper said it released a patch that corrects the issue. The company said it wasn’t aware of “any malicious exploitation” of the security loophole, but noted there likely wasn’t a way to reliably detect if a device had been compromised because hackers could have easily erased the evidence.
