Power authority slips away on Navajo Nation

5G Energy Costs highlight base station power consumption, carrier electricity bills, and carbon emissions in China, while advances in energy efficiency, sleep modes, and cooling systems aim to optimize low-latency networks and reduce operational expenses.

Key Points

5G energy costs rise with power-hungry base stations, yet per-bit efficiency and sleep modes help cut bills.

✅ 5G base stations use ~4x 4G electricity

✅ Per-bit 5G energy efficiency is ~4x better than 4G

✅ Sleep modes and advanced cooling reduce OPEX and emissions

As 5G developers look desperately for a "killer app" to prove the usefulness of the superfast wireless technology, mobile carriers in China are complaining about the high energy cost of 5G signal towers.

And the situation is, according to experts, more complicated than many have thought.

The costly 5G

5G technology can be 10 or more times faster than 4G and significantly more responsive to users' input, but the speed comes at a cost.

A 5G base station consumes "four times more electricity" than its 4G counterpart, said Ding Haiyu, head of wireless and terminals at the China Mobile Research Institute, during a symposium on 5G and carbon neutrality in Beijing, a key focus for countries pursuing a net-zero grid by 2050 worldwide.

But concerning each bit of data transmitted, 5G is four times more energy-efficient than 4G, according to Ding.

This means that mobile carriers should fully occupy their 5G network for as long time as possible, but that can be hard at this moment, as many people are still holding 4G smartphones.

"When the 5G stations are running without people using them, they are really electricity guzzlers," said Zhu Qingfeng, head of power supply design at China Information Technology Designing and Consulting Institute Co., Ltd., who represents China Unicom at the symposium. "Each of the three telecom carrier giants are emitting about ten million tonnes of carbon in the air."

"We have to shut down some 5G base stations at night to reduce emission," he added.

Some utilities are testing fuel cell solutions to keep backup batteries charged much longer, supporting network resilience at lower emissions.

A representative from China Telecom said electricity bills of the nationwide carrier reached a new high of 100 billion yuan (about $15 billion) a year, mirroring the power challenges for utilities as data center demand booms elsewhere.

Getting better

While admitting the excessive cost of 5G, experts at the symposium also agreed that the situation is improving, even as climate pressures on the grid continue to mount.

Ding listed a series of recent technologies that is helping reduce the energy use of 5G, including chips of better process, automatic sleeping and wake-up of base stations and liquid nitrogen-based cooling system, and superconducting cables as part of ongoing upgrades.

"We are aiming at halving the 5G electricity cost to only two times of 4G in two years," Ding said.

Experts also discussed the possibility of making use of 5G's low latency features to help monitoring the electricity grid, thus making the digital grid smarter and more cost effective.

G's energy cost is seen as a hot topic for the incoming World 5G Convention in Beijing in early August, alongside smart grid transformation themes. Stay tuned to CGTN Digital as we bring you the latest news about the convention and 5G technology.

Power Grid Attacks surge across substations and transmission lines, straining critical infrastructure as DHS and FBI cite vandalism, domestic extremists, and cybersecurity risks impacting resilience, outages, and grid reliability nationwide.

Key Points

Power Grid Attacks are deliberate strikes on substations and lines to disrupt power and weaken grid reliability.

✅ Physical attacks rose across multiple states and utilities.

✅ DHS and FBI warn of threats to critical infrastructure.

✅ Substation security and grid resilience upgrades urged.

Even before Christmas Day attacks on power substations in five states in the Pacific Northwest and Southeast, similar incidents of attacks, vandalism and suspicious activity were on the rise.

Federal energy reports through August – the most recent available – show an increase in physical attacks at electrical facilities across the nation this year, continuing a trend seen since 2017.

At least 108 human-related events were reported during the first eight months of 2022, compared with 99 in all of 2021 and 97 in 2020. More than a dozen cases of vandalism have been reported since September.

The attacks have prompted a flurry of calls to better protect the nation's power grid, with a renewed focus on protecting the U.S. power grid across sectors, but experts have warned for more than three decades that stepped-up protection was needed.

Attacks on power stations on the rise 
Twice this year, the Department of Homeland Security warned "a heightened threat environment" remains for the nation, including its critical infrastructure amid reports of suspected Russian breaches of power plant systems. 

At least 20 actual physical attacks were reported, compared with six in all of 2021. 
Suspicious-activity reports jumped three years ago, nearly doubling in 2020 to 32 events. In the first eight months of this year, 34 suspicious incidents were reported.
Total human-related incidents – including vandalism, suspicious activity and cyber events such as Russian hackers and U.S. utilities in recent years – are on track to be the highest since the reports started showing such activity in 2011.

Attacks reported in at least 5 states
Since September, attacks or potential attacks have been reported on at least 18 additional substations and one power plant in Florida, Oregon, Washington and the Carolinas. Several involved firearms.

• In Florida: Six "intrusion events" occurred at Duke Energy substations in September, resulting in at least one brief power outage, according to the News Nation television network, which cited a report the utility sent to the Energy Department. Duke Energy spokesperson Ana Gibbs confirmed a related arrest, but the company declined to comment further.
• In Oregon and Washington state: Substations were attacked at least six times in November and December, with firearms used in some cases, local news outlets reported. On Christmas Day, four additional substations were vandalized in Washington State, cutting power to more than 14,000 customers.
• In North Carolina: A substation in Maysville was vandalized on Nov. 11. On Dec. 3, shootings that authorities called a "targeted attack" damaged two power substations in Moore County, leaving tens of thousands without power amid freezing temperatures.
• In South Carolina: Days later, gunfire was reported near a hydropower plant, but police said the shooting was a "random act."

It's not yet clear whether any of the attacks were coordinated. After the North Carolina attacks, a coordinating council between the electric power industry and the federal government ordered a security evaluation.

FBI mum on its investigations
The FBI is looking into some of the attacks, including cyber intrusions where hackers accessed control rooms in past cases, but it hasn't said how many it's investigating or where. 

Shelley Lynch, a spokesperson for the FBI's Charlotte field office, confirmed the bureau was investigating the North Carolina attack. The Kershaw County Sheriff's Office reported the FBI was looking into the South Carolina incident.

Utilities in Oregon and Washington told news outlets they were cooperating with the FBI, but spokespeople for the agency's Seattle and Portland field offices said they couldn't confirm or deny an investigation.

Could domestic extremists be involved?
In January, the Department of Homeland Security said domestic extremists had been developing "credible, specific plans" since at least 2020, including a Neo-Nazi plot against power stations detailed in a federal complaint, and would continue to "encourage physical attacks against electrical infrastructure."

In February, three men who ascribed to white supremacy and Neo-Nazism pleaded guilty to federal crimes related to a scheme to attack the grid with rifles.

In a news release, Timothy Langan, assistant director of the FBI’s Counterterrorism Division, said the defendants "wanted to attack regional power substations and expected the damage would lead to economic distress and civil unrest."

Why is the power grid so hard to protect?
Industry experts, federal officials and others have warned in one report after another since at least 1990 that the power grid was at risk, and a recent grid vulnerability report card highlights dangerous weak points, said Granger Morgan, an engineering professor at Carnegie Mellon University who chaired three National Academies of Sciences reports.

The reports urged state and federal agencies to collaborate to make the system more resilient to attacks and natural disasters such as hurricanes and storms. 

"The system is inherently vulnerable, with the U.S. grid experiencing more blackouts than other developed nations in one study. It's spread all across the countryside," which makes the lines and substations easy targets, Morgan said. The grid includes more than 7,300 power plants, 160,000 miles of high-voltage power lines and 55,000 transmission substations.

One challenge is that there's no single entity whose responsibilities span the entire system, Morgan said. And the risks are only increasing as the grid expands to include renewable energy sources such as solar and wind, he said.

Venezuela Power Outage cripples the national grid after a massive blackout; alleged cyber attacks at Guri Dam and Caracas, damaged transmission lines, CORPOELEC restoration, looting, water shortages, and sanctions pressure compound recovery.

Key Points

A March 2019 blackout crippling Venezuela's grid amid alleged cyber attacks, equipment failures, and slow restoration.

✅ Power restored partially after 96 hours across all states

✅ Alleged cyber attacks at Guri Dam and Caracas systems

✅ CORPOELEC urges reduced load during grid stabilization

Venezuelan authorities continue working to bring back online the electric grid following a massive outage that started on Thursday, March 7.

According to on-the-ground testimonies and official sources, power finally began to reach Venezuela’s western states, including Merida and Zulia, on Monday night, around 96 hours after the blackout started. Electricity has now been restored at least in some areas of every state, with authorities urging citizens, as seen in Ukraine's efforts to keep lights on during crisis, to avoid using heavy usage devices while efforts to restore the whole grid continue.

President Nicolas Maduro gave a televised address on Tuesday evening, offering more details about the alleged attack against the country’s electrical infrastructure. According to Maduro, both the computerized system in the Guri Dam, on Thursday afternoon, and the central electrical “brain” in Caracas, on Saturday morning, suffered cyber attacks, while recovery was delayed by physical attacks against transmission lines and electrical substations, a pattern seen in power outages in western Ukraine as well.

“The recovery has been a miracle by CORPOELEC (electricity) workers” he said, vowing that a “battle” had been won.

Maduro claimed that the attacks were directed from Chicago and Houston and that more evidence would be presented soon. The Venezuelan president had announced on Monday that two arrests were made in connection to alleged acts of sabotage against the communications system in the Guri Dam.

Venezuela’s electrical grid has suffered from poor maintenance and sabotage in recent years, with infrastructure strained by under-investment and Washington’s economic sanctions further compounding difficulties, with parallels to electricity inequality in California highlighting broader systemic challenges, though causes differ.

The extended power outage saw episodes of lootings take place, especially in the Zulia capital of Maracaibo. Food warehouses, supermarkets and a shopping mall were targeted according to reports and footage on social media.

Isolated episodes of protests and lootings were also reported in other cities, including some sectors of Caracas. A video spread on social media appeared to show a violent confrontation in the eastern city of Maturin in which a National Guardsman was shot dead.

While electricity has been gradually restored, public transportation and other services have yet to be reactivated, a contrast with U.S. grid resilience during COVID-19 where power systems remained stable, with the government suspending work and school activities until Wednesday.

In Caracas, attention has now turned to water. Shortages started to be felt after the water pumping system in the nearby Tuy valley was shut down amid the electricity blackout, underscoring that electricity is civilization in conflict zones, as interdependent systems cascade. Authorities announced on Tuesday afternoon that the system was due to resume supplying water to the capital metropolitan region.

Some communities protested the lack of water on Monday and long queues formed at water distribution points, with local authorities looking to send water tanks to supply communities and guarantee the normal functioning of hospitals.

The Venezuelan government has yet to release any information concerning casualties in hospitals, with NGO Doctors for Health reporting 24 dead as of Monday night following alleged contact with multiple hospitals. Higher figures, including claims of 80 newborns dead in Maracaibo, have been denied by local sources.

Self-proclaimed “Interim President” Juan Guaido has blamed the electricity crisis on government mismanagement and corruption, dismissing the government’s cyber attack thesis on the grounds that the system is analog, and attributing the national outage to a lack of qualified personnel needed to reactivate the grid. However, these claims have been called into question by people with knowledge of the system.

Guaido called for street protests on Tuesday afternoon which saw small groups momentarily take to streets in Caracas and other cities, or banging pots and pans from windows.

The opposition-controlled National Assembly, which has been in contempt of court since 2016, approved a decree on Monday declaring a state of “national alarm,” blaming the government for the current crisis and issuing instructions for public officials and security forces.

Likewise on Tuesday, Venezuelan Attorney General Tarek William Saab announced that an investigation was being opened against Guaido regarding his alleged responsibility for the recent power outage. Saab explained that this investigation would add to the previous one, opened on January 29, as well as determine responsibilities in instigating violence.

Hydro One CEO Pay Cap sets executive compensation at $1.5 million under Ontario's provincial directive, linking incentives to transmission and distribution cost reductions, governance improvements, and board pay limits at the electricity utility.

Key Points

The Hydro One CEO Pay Cap limits pay to $1.5M, linking incentives to cost reductions and defined targets.

✅ Base salary set at $500,000 per year.

✅ Incentives capped at $1,000,000, tied to cost cuts.

✅ Board pay capped: chair $120,000; members $80,000.

Hydro One has agreed to cap the annual compensation of its chief executive at $1.5 million, the provincial utility said Friday, acquiescing to the demands of the Progressive Conservative government.

The CEO's base salary will be set at $500,000 per year, while short-term and long-term incentives are limited to $1 million. Performance targets under the pay plan will include the CEO's contributions to reductions in transmission and distribution costs, even as Hydro One has pursued a bill redesign to clarify charges for customers.

The framework represents a notable political victory for Premier Doug Ford, who vowed to fire Hydro One's CEO and board during the campaign and promised to reduce the annual earnings of Hydro One's board members.

In February, the province issued a directive to the board, ordering it to pay the utility's CEO no more than the $1.5 million figure it has now agreed to, as part of a broader push to lower electricity rates across Ontario.

Hydro One and the government had been at loggerheads over executive compensation, with the company refusing repeated requests to slash the CEO pay below $2,775,000. The board argued it would have difficulty recruiting suitable leaders for anything less, even as customers contend with a recovery rate that could raise hydro bills.

Further, the company agreed to pay the board chair no more than $120,000 annually and board members no more than $80,000 — figures Energy Minister Greg Rickford had outlined in his directive last month, amid calls for cleaning up Ontario's hydro mess from policy commentators.

"Hydro One's compliance with this directive allows us to move forward as a province. It sets the company on the right course for the future, proving that it can operate as a top-class electricity utility while reining in executive compensation and increasing public transparency," Rickford said in a statement issued Friday morning.

North Carolina Power Outages continue after Hurricane Florence, with Wilmington and Eastern Carolina facing flooding, storm damage, and limited access as Duke Energy crews and mutual aid work on restoration across affected counties.

Key Points

Outages after Hurricane Florence, with Wilmington and Eastern Carolina hardest hit as crews restore service amid floods.

✅ Over 250,000 outages statewide as of early Wednesday

✅ Wilmington cut off by flooding, hindering utility access

✅ Duke Energy and EMC crews conduct phased restoration

Power is slowly being restored to Eastern Carolina residents after Hurricane Florence made landfall near Wilmington on Friday, September 15, a scenario echoed by storm-related outages in Tennessee in recent days.

On Monday, more than half a million people remained without power across the state, a situation comparable to post-typhoon electricity losses in Hong Kong reported elsewhere.

As of Wednesday morning at 1am, the Dept. of Public Safety reports 252,596 total power outages in North Carolina, and utilities continue warning about copper theft hazards during restoration.

More than half of those customers are in Eastern Carolina.

More than 32,000 customers are without power in Carteret County and roughly 21,000 are without power in Onslow County.

In Craven County, roughly 15,000 people remain without power Wednesday morning.

Many of the state's outages are effecting the Wilmington area, where Florence made landfall and widespread flooding is still cutting off the city from outside resources, similar to how a fire-triggered outage in Los Angeles disrupted service regionally.

Heavy rain, strong winds and now flooded roadways have hindered power crews, challenges that utility climate adaptation aims to address while many of them have out-of-state or out-of-town help working to restore power to so many people.
