California power grid passes first heat wave test amid gas shortage

Lost Angeles skyline

(Reuters) – California’s power grid passed its first test of the summer with no rolling blackouts on Monday, when customers cranked up their air conditioners as temperatures soared into the triple-digits for the second consecutive day in some southern parts of the state.

The California Independent System Operator, which manages the state’s power grid, issued a so-called flex alert on Sunday, urging homes and businesses to conserve energy on Monday afternoon.

As consumers heeded that call and temperatures on Monday came in a little cooler than expected, the ISO cut its peak power demand projection for the day to 43,728 megawatts from 45,316 MW.

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. The storage field, California’s largest, has been effectively idled since a major well rupture there last autumn.

So far, the ISO has not issued another flex alert for Tuesday but said on its website it would be “helpful” if customers conserve energy.

With cooler temperatures expected for the rest of the week, the ISO forecast demand would peak at 42,581 MW on Tuesday and just 39,036 on Wednesday.

AccuWeather meteorologists forecast the mercury would reach 87 degrees Fahrenheit (31 Celsius) in Los Angeles on Tuesday before falling to a near-normal 82 degrees on Wednesday. They had exceeded 100 degrees on Monday.

With Aliso Canyon shut down, state regulators have warned that the Los Angeles area faces up to 14 days of gas shortages severe enough to trigger blackouts this summer.

Aliso Canyon, owned by Sempra Energy’s Southern California Gas Co unit, normally supplies the region’s 17 gas-fired power plants, hospitals, refineries and other key parts of the state’s economy.

California power grid prepares for heatwave, possible natgas shortage

By Scott DiSavino

(Reuters) – California will have its first test of plans to keep the lights on this summer following the shutdown of the key Aliso Canyon natural gas storage facility as temperatures in the Los Angeles area are forecast to hit triple digits this week.

With record-setting heat and air conditioning demand expected in Southern California, the state’s power grid operator issued a so-called “flex alert,” urging consumers to conserve energy to help prevent rotating power outages – which could occur regardless.

Electricity demand is expected to rise during the unseasonable heatwave on Monday and Tuesday, with forecast system-wide use expected to top 45,000 megawatts, said the California Independent System Operator (ISO), which manages electricity flow through the state. That compares with a peak demand of 47,358 MW last year and the all-time high of 50,270 MW set in July 2006.

That could put stress on the power grid, particularly with the shut-in of Aliso Canyon, following a massive leak at the underground storage facility in October. The facility, in the San Fernando Valley, is the second largest storage field in the western United States, according to federal data, and therefore crucial for power generation.

All customers, including homes, hospitals, oil refineries and airports are at risk of losing power at some point this summer because a majority of electric generating stations in California use gas as their primary fuel. In April, millions of electric customers in Southern California were warned they could suffer power outages on up to 14 days this summer due to the closure.

The ISO said it was working with gas and power utilities and state energy agencies to mitigate potential reliability issues related to the limited operations at Aliso Canyon.

“We are confident we have a strong plan in place to meet the operational challenges posed by the upcoming hot temperatures,” ISO CEO Steve Berberich said, adding that consumer conservation efforts would be key.

ROTATING OUTAGES

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

Southern California Gas (SoCalGas), the nation’s biggest gas distribution utility and owner of Aliso Canyon, detected the leak in October and plugged it in February.

SoCalGas is a unit of California energy company Sempra Energy.

State regulators will not allow SoCalGas to inject fuel into the facility until the company inspects all of its 114 wells.

Aliso Canyon is the biggest of four SoCalGas storage fields. It provides service to the region’s 17 gas-fired power plants, hospitals, refineries, and other key parts of California’s economy.

In the summer (April through October), SoCalGas strives to completely fill 86.2-billion cubic feet (bcf) Aliso Canyon to prepare for the upcoming winter heating season when gas demand peaks.

State regulators, however, ordered the company in January to reduce the amount of working gas in Aliso Canyon to just 15 bcf and use that fuel to reduce the risk of gas curtailments and power interruptions this summer.

Unlike some other gas transmission systems that can store large amounts of so-called linepack gas in pipelines, like PG&E Corp in northern California, SoCalGas cannot function with only pipeline or storage supplies.

That makes storage fields much more critical for SoCalGas and the 21 million residents it supports.

SoCalGas uses Aliso Canyon to provide gas to power generators that cannot be met with pipeline flows alone on about 10 days per month during the summer, according to state agencies.

Colin brings strong Wind, heavy rain, flooding to southeast U.S.

Tropical Storm Colin is seen over the Gulf of Mexico

(Reuters) – Strong winds and heavy rainfall were expected across the southeastern United States on Tuesday even as the center of Tropical Storm Colin was moving into the Atlantic Ocean.

The storm was 90 miles (145 km) southwest of Charleston, South Carolina, at 4 a.m. eastern time (0800 GMT) and moving at 31 mph, the U.S. National Hurricane Center in Miami said.

A tropical storm warning was in effect from the Altamaha Sound Georgia to Oregon Inlet in North Carolina on Tuesday morning. On its forecast path, Colin was to barrel along the coast of the southeastern United States before moving out to sea during the day.

As 50 mph winds were expected in the region, a tornado was reported in Lee County Florida, the National Weather Service said. The storm was forecast dump as much as 1 to 3 inches more of rain as flash flood warnings and watches were in effect across the region, the hurricane center said.

Florida Governor Rick Scott, who had declared a state of emergency on Monday in 34 of the state’s 67 counties, said more than 6,000 Florida National Guard members were activated and ready for deployment.

Flooding and property damage resulting from the fierce winds remained threats into the day, and far beyond the storm’s immediate path, forecasters warned.

A statement from Scott’s office warned residents to be wary of rip currents and the possibility of 10 foot (3 m) waves along the Gulf Coast.

“It is critical that all Floridians use caution and remain alert,” he said in the statement.

In the St. Petersburg beach town of Gulfport and in Charleston, South Carolina, roads were flooded, local authorities said on social media.

About 10,000 customers were without power in Florida, Georgia, South Carolina and North Carolina, utilities reported.

The storm also threatened crops in Florida, the country’s biggest citrus producer, which sent U.S. orange juice futures on Monday to their highest in more than two years.

Colin is part of a brisk start to the Atlantic hurricane season that runs through Nov. 30. Over the U.S. Memorial Day holiday weekend, the Carolinas were lashed by heavy rain and winds from Tropical Storm Bonnie.

Electricity supply gradually returns in Syria after massive outage

BEIRUT (Reuters) – Syria’s electricity supply was gradually returning after it was cut across the country on Thursday and Internet connections were briefly disrupted, state media said.

SANA news agency quoted the electricity minister saying that the network was returning and would be restored to its earlier capacity by midnight. It did not say what caused the cut.

It said earlier that the “electricity work has been cut in all governorates. Attempts to find the cause of the outage have begun.”

A Reuters witness confirmed that electricity had gone down in Damascus, and the Syrian Observatory for Human Rights, which monitors the five-year-old conflict in Syria, said that power had been cut in the “vast majority of governorates”.

SANA reported the Syria Telecommunications Company as saying Internet services were partially halted on Thursday “as a result of sudden damage to one of the network hubs”, but were later restored.

More than 170,000 without power after New England snowstorm

More than 170,000 homes and businesses were without power on Friday afternoon after a winter storm brought more than a foot of snow to parts of southern New England.

The Massachusetts Emergency Management Agency reported 99,439 customers were without power, while Eversource indicated 48,149 of its Connecticut customers were experiencing outages. National Grid said the lights were off for 22,585 of its customers in Rhode Island.

The outages came after a winter storm dumped double-digit snowfall totals in all three states, according to the National Weather Service. That included 13 inches near Stafford Springs, Connecticut, 12.5 inches near Worcester, Massachusetts, and a foot in Burrillville, Rhode Island.

The Weather Channel is calling the storm Winter Storm Lexi.

Selected cities in New York, New Hampshire and Maine had received more than 7 inches of snow as of 3 p.m. local time, according to the National Weather Service, and counties in Maine, Rhode Island, Connecticut and Massachusetts were still under winter storm warnings at 4:30.

In a statement, Connecticut Governor Dannel P. Malloy said he was receiving updates from local utility companies and “remained concerned” about the power outages. Temperatures were expected to dip into the teens and 20s overnight, according to the National Weather Service.

“They are working to restore power to those who have lost it and continue to deploy crews to alleviate the situation,” Malloy said in his statement, referring to the utility companies. “However, we urge patience – the situation may take time to resolve.”

The storm also disrupted travel in the region.

More than 200 flights to or from Boston Logan International Airport had been cancelled, according to flight monitoring website FlightAware.com, and another 213 were delayed. There were more than 300 cancellations and 300 delays at LaGuardia Airport, FlightAware reported.

The Connecticut State Police tweeted it had responded to 341 crashes and a portion of Interstate 84 was temporarily closed. It encouraged drivers to stay off the road if possible.

Blizzard pummels midwest, knocking out power and shutting down interstates

Parts of the midwest were bracing for blizzard conditions on Tuesday morning as a powerful winter storm continued east, knocking down power lines and shutting down major highways.

The National Weather Service issued winter storm or blizzard warnings in portions of nine states and wind advisories in several more as the storm brought more heavy snow to the nation.

Radar showed precipitation falling over Nebraska, Iowa, Illinois and Minnesota on Tuesday morning. The storm was expected to reach Wisconsin and northern Michigan this afternoon.

Blizzard warnings were issued in parts of Minnesota, Iowa, South Dakota, Nebraska and Kansas.

The National Weather Service warned that those areas could receive between six to 15 inches of snow and wind gusts of up to 50 mph, which could reduce visibility and lead to road closures.

Notably, a roughly 300-mile stretch of Interstate 70 between Denver International Airport and Hays, Kansas, was closed, according to the Colorado and Kansas transportation departments. A 225-mile stretch of U.S. 36 that largely parallels the interstate highway was also closed down.

The Colorado Department of Transportation blamed the closures on “whiteout conditions.” The National Weather Service said one mountainous part of the state received 33 inches of snow.

The Weather Channel is referring to the storm as Winter Storm Kayla.

Portions of Colorado and Wyoming were under winter storm warnings, as were other parts of the five states in which blizzard warnings were issued. The storm wasn’t expected to bring snow to the south, though the National Weather Service issued wind advisories in parts of Kansas, Missouri, Oklahoma, Texas, Arkansas, Illinois, Indiana, Kentucky, Tennessee, Alabama, Mississippi and North Carolina because strong sustained winds were expected in those regions.

Some states should expect severe thunderstorms, the National Weather Service warned, and there was a possibility that tornadoes could touch down in Alabama, Mississippi and the Ohio River Valley later tonight. The service had yet to issue any thunderstorm or tornado watches.

Residents of all of the above states are encouraged to monitor their local forecasts.

The storm has already brought wind gusts of at least 70 mph to six states, according to the National Weather Service, including 90-mph-plus gusts in Texas, California and New Mexico.

About 143,000 people in Southern California were without power on Sunday, according to local utility companies Southern California Edison and the Los Angeles Department of Water and Power, though those numbers were down to about 12,000 as of early Tuesday morning.

The National Weather Service reported that gusts reached 40 mph in Nebraska, and parts of the state received between seven and 12.5 inches of snow as of 8 a.m. Tuesday. More was expected.

The Omaha Public Power District said about 20,000 customers were without power, while the Lincoln Electric System said it was working to turn the lights back on for about 1,800 customers.

The Nebraska Department of Transportation said it closed a 112-mile stretch of Interstate 80 between Kearney and York, and several other state routes were impassible or fully covered.

Some parts of Kansas received 10 inches of snow as of Tuesday morning, the National Weather Service reported. Several state and U.S. highways in the state’s northwest corner were closed to traffic, the state Department of Transportation reported.

More than 130 flights to or from Denver International Airport were cancelled as of mid-day Tuesday, according to flight monitoring website FlightAware.com. The Colorado Department of Transportation said it also closed a 159-mile stretch of Interstate 76 and several state highways.

The storm also brought a foot or more of snow to several locations in Wyoming, according to the National Weather Service, including 24.3 inches near Driggs.

Totals weren’t yet available for Iowa, though the state Department of Transportation reported that a part of Interstate 29 was closed near Sioux City and many roads were fully covered.

U.S. braces for winter storm as thousands remain without power in California

Portions of 13 states were under winter storm warnings on Monday morning as a powerful storm that was already being blamed for thousands of power outages was set to move east.

More than 143,000 customers in southern California were without power on Sunday, local utility companies reported, after high winds toppled trees and knocked over power lines.

As of Monday morning, Southern California Edison reported about 40,000 customers were still in the dark (down from 80,000 earlier on Sunday) and the Los Angeles Department of Water and Power said it had turned the lights back on for 51,000 of its 63,000 affected customers.

Other parts of the country were bracing for the arrival of snow and high winds.

The National Weather Service issued blizzard warnings in parts of Kansas, Nebraska and Iowa, saying those areas could see between 8 and 13 inches of snow between tonight and Wednesday. The service called for wind gusts of up to 45 mph, which could blow snow and reduce visibility.

The broader winter storm warnings covered parts of California, Nevada, Utah, Arizona, New Mexico, Colorado, Wyoming, Nebraska, Kansas, Iowa, Minnesota, Wisconsin and Michigan.

Residents in the warning areas should monitor local forecasts. The National Weather Service said some cities could receive 4 to 8 inches of snow, while higher elevations could see 1 to 2 feet.

The Weather Channel is referring to the impending storm as Winter Storm Kayla.

High wind warnings were issued for parts of California, Arizona, New Mexico and Texas. The service warned gusts of 70 to 75 mph were possible in some areas and could damage property.

Several areas already reported gusts far above those levels.

The National Weather Service said gusts reached 95 mph at San Augustin Pass near Las Cruces, New Mexico. In California, Malibu and Harrison Park saw gusts of 87 and 85 mph, respectively.

The wind gusts knocked down trees, in some cases blocking traffic.

The California Highway Patrol tweeted a downed tree temporarily blocked four lanes of the Ventura Freeway on Sunday. The agency also reported that snow shut down a stretch of Interstate 5 near Grapevine on early Monday morning, though the freeway later reopened.

The storm was complicating air travel, too.

According to flight monitoring website FlightAware.com, 508 flights to or from Denver International Airport had been cancelled as of 11:45 a.m. ET on Monday.

Some 225 miles southwest of the airport, the National Weather Service reported Colorado’s Kebler Pass was hit with 23 inches of snow between Saturday night and Monday morning. Snowfall totals reached 16 inches near California’s Mammoth Lakes, located in the Sierra Nevada mountain range, while other parts of the state received more than two inches of rain.

Ukraine to review cyber defenses after airport targeted from Russia

KIEV (Reuters) – Ukrainian authorities will review the defenses of government computer systems, including at airports and railway stations, after a cyber attack on Kiev’s main airport was launched from a server in Russia, officials told Reuters on Monday.

Malware similar to that which attacked three Ukrainian power firms in late December was detected last week in a computer in the IT network of Kiev’s main airport, Boryspil. The network includes the airport’s air traffic control.

Although there is no suggestion at this stage that Russia’s government was involved, the cyber attacks have come at a time of badly strained relations between Ukraine and Russia over a nearly two-year-long separatist conflict in eastern Ukraine.

“In connection with the case in Boryspil, the ministry intends to initiate a review of anti-virus databases in the companies which are under the responsibility of the ministry,” said Irina Kustovska, a spokeswoman for Ukraine’s infrastructure ministry, which oversees airports, railways and ports.

Ukraine’s state-run Computer Emergency Response Team (CERT-UA) issued a warning on Monday of the threat of more attacks.

“The control center of the server, where the attacks originate, is in Russia,” military spokesman Andriy Lysenko said by telephone, adding that the malware had been detected early in the airport’s system and no damage had been done.

A spokeswoman for the airport said Ukrainian authorities were investigating whether the malware was connected to a malicious software platform known as “BlackEnergy”, which has been linked to other recent cyber attacks on Ukraine. There are some signs that the attacks are linked, she said.

“Attention to all system administrators … We recommend a check of log-files and information traffic,” CERT-UA said in a statement.

In December three Ukrainian regional power firms experienced short-term blackouts as a result of malicious software in their networks. Experts have described the incident as the first known power outage caused by a cyber attack.

A U.S. cyber intelligence firm in January traced the attack back to a Moscow-backed group known as Sandworm.

The Dec. 23 outage at Western Ukraine’s Prykarpattyaoblenergo cut power to 80,000 customers for about six hours, according to a report from a U.S. energy industry security group.

Ukraine’s SBU state security service has blamed Russia, but the energy ministry said it would hold off on attribution until after it completes a formal probe.

Destructive Winter Storm Reaches New England

A powerful and deadly winter storm that brought heavy snow and widespread flooding to the United States continued to travel east on Tuesday morning, leaving more destruction in its path.

The National Weather Service issued winter weather advisories and winter storm warnings in parts of Pennsylvania, New York and New England as the storm was poised to finally exit the country. But the storm’s fury was still being felt across the nation, particularly in the Great Plains and Ohio and Mississippi valleys, where numerous flood warnings remained in effect.

The National Oceanic and Atmospheric Administration (NOAA) said 438 river gauges across the nation were in flood stage on Tuesday morning, 53 of which were experiencing “major flooding.” Most of them were clustered in the central United States, though a few were in the southeast. In many locations, floodwaters had already reached or were threatening to surpass historic levels.

Fueled by 10 inches of rainfall in the vicinity, the Illinois River near Tahlequah, Oklahoma, reached an all-time high crest of 30.69 feet on Monday, more than 2.5 feet above the previous record that was set 65 years ago, the NOAA reported. The floodwaters had receded to about 21 feet there on Tuesday morning, though that was still more than three feet above the threshold for what is considered major flooding. The NOAA said parts of Texas, Arkansas and Missouri also saw 10 or more inches of rain, including a storm-high 12.25 inches near Union, Missouri. The storm also packed a powerful punch in Illinois, dumping 9.98 inches of rain near Roxana.

Rising waters prompted the mayor of St. Louis to declare a city emergency. Just south of the city in Arnold, the NOAA reported Meramec River was already experiencing major flooding, and was expected to surpass its all-time high level of 45.3 feet later this week. That water flows into the Mississippi River, and the NOAA projected that the further-south riverside communities of Chester, Illinois, and Cape Girardeau, Missouri, were also expected to tie or break local crest records.

That’s just a sampling of the storm’s flooding, and the 438 river gauges do not necessarily cover the lakes or other water bodies causing floods. In southern Missouri, for example, the U.S. Army Corps of Engineers reported that waters at Table Rock Lake rose approximately 17 feet between Monday and Tuesday, fueling a massive release of water into flood-prone Lake Taneycomo. The United States Geological Survey reported that waters at Ozark Beach Dam in Forsyth, some 20 miles away from Table Rock Lake, rose three feet between Monday and Tuesday.

The storm brought more than just flooding and heavy rains.

More than three inches of sleet fell in Iowa and Illinois, the NOAA reported. But an inch was enough to snarl traffic at Chicago O’Hare International Airport, one of the world’s busiest.

Flight monitoring website FlightAware.com reported that 1,366 flights to or from the airport were cancelled on Monday, more than half of the airport’s scheduled traffic. Another 303 flights involving Chicago Midway International Airport were also cancelled, according to FlightAware, and lingering effects of the storm caused an additional 236 cancellations at O’Hare on Tuesday.

According to NOAA data, no place came close to receiving the 41 inches of snow the storm dumped on Bonito Lake, located in a mountain range in New Mexico. But the storm did produce more than nine inches of snow in Oklahoma, Iowa, Michigan, Minnesota, Wisconsin and Texas.

The storm knocked out power to tens of thousands in Oklahoma, according to utility companies.

While the storm appears seems to have weakened considerably, it’s still packing a punch. According to the National Weather Service, parts of Maine could receive up to a foot of snow.

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.
