A malfunction caused a shutdown of a nuclear power reactor at one of South Korea's atomic power plants, authorities said.

Operators at the Younggwang Nuclear Power Plant in South Cholla Province said operations of Unit No. 1 were suspended after a malfunction was detected.

"There was no radiation leakage, and once experts determine the exact cause of the malfunction, operations will begin again," said a spokesman for the plant, located 322 kilometres south of Seoul. Minor malfunctions that could lead to a shutdown are not reported to the International Atomic Energy Agency.

The generator is one of six units in the power plant. It went into commercial operation in August 1986 and has generates 950 megawatt of electricity.

In addition to the Younggwang plant, South Korea operates 20 nuclear reactors throughout the country that fuel 40 per cent of the country's electricity needs.

Finland Investigates Russian Ship After Electricity Cable Damage

Finland Shadow Fleet Cable Investigation details suspected Russia-linked sabotage of Baltic Sea undersea cables, AIS dark activity, and false-flag tactics threatening critical infrastructure, prompting NATO and EU vigilance against hybrid warfare across Northern Europe.

 

Key Points

Finland probes suspected sabotage of undersea cables by a Russia-linked vessel using flag of convenience and AIS off.

✅ Undersea cable damage in Baltic Sea sparks security alerts

✅ Suspected shadow fleet ship ran AIS dark under false flag

✅ NATO and EU boost maritime surveillance, critical infrastructure

 

In December 2024, Finland launched an investigation into a ship allegedly linked to Russia’s “shadow fleet” following a series of incidents involving damage to undersea cables. The investigation has raised significant concerns in Finland and across Europe, as it suggests possible sabotage or other intentional acts related to the disruption of vital communication and energy infrastructure in the Baltic Sea region. This article explores the key details of the investigation, the role of Russia’s shadow fleet, and the broader geopolitical implications of this event.

The "Shadow Fleet" and Its Role

The term “shadow fleet” refers to a collection of ships, often disguised or operating under false flags, that are believed to be part of Russia's covert maritime operations. These vessels are typically used for activities such as smuggling, surveillance, and potentially military operations, mirroring the covert hacker infrastructure documented by researchers in related domains. In recent years, the "shadow fleet" has been under increasing scrutiny due to its involvement in various clandestine actions, especially in regions close to NATO member countries and areas with sensitive infrastructure.

Russia’s "shadow fleet" operates in the shadows of regular international shipping, often difficult to track due to the use of deceptive practices like turning off automatic identification systems (AIS). This makes it difficult for authorities to monitor their movements and assess their true purpose, raising alarm bells when one of these ships is suspected of being involved in damaging vital infrastructure like undersea cables.

The Cable Damage Incident

The investigation was sparked after damage was discovered to an undersea cable in the Baltic Sea, a vital link for communication, data transmission, and energy supply between Finland and other parts of Europe. These undersea cables are crucial for everything from internet connections to energy grid stability, with recent Nordic grid constraints underscoring their importance, and any disruption to them can have serious consequences.

Finnish authorities reported that the damage appeared to be deliberate, raising suspicions of potential sabotage. The timing of the damage coincides with a period of heightened tensions between Russia and the West, particularly following the escalation of the war in Ukraine, with recent strikes on Ukraine's power grid highlighting the stakes, and ongoing geopolitical instability. This has led many to speculate that the damage to the cables could be part of a broader strategy to undermine European security and disrupt critical infrastructure.

Upon further investigation, a vessel that had been in the vicinity at the time of the damage was identified as potentially being part of Russia’s "shadow fleet." The ship had been operating under a false flag and had disabled its AIS system, making it challenging for authorities to track its movements. The vessel’s activities raised red flags, and Finnish authorities are now working closely with international partners to ascertain its involvement in the incident.

Geopolitical Implications

The damage to undersea cables and the suspected involvement of Russia’s "shadow fleet" have broader geopolitical implications, particularly in the context of Europe’s security landscape. Undersea cables are considered critical infrastructure, akin to electric utilities where intrusions into US control rooms have been documented, and any deliberate attack on them could be seen as an act of war or an attempt to destabilize regional security.

In the wake of the investigation, there has been increased concern about the vulnerability of Europe’s energy and communication networks, which are increasingly reliant on these undersea connections, and as the Baltics pursue grid synchronization with the EU to reduce dependencies, policymakers are reassessing resilience measures. The European Union, alongside NATO, has expressed growing alarm over potential threats to this infrastructure, especially as tensions with Russia continue to escalate.

The incident also highlights the growing risks associated with hybrid warfare tactics, which combine conventional military actions with cyberattacks, including the U.S. condemnation of power grid hacking as a cautionary example, sabotage, and disinformation campaigns. The targeting of undersea cables could be part of a broader strategy by Russia to disrupt Europe’s ability to coordinate and respond effectively, particularly in the context of ongoing sanctions and diplomatic pressure.

Furthermore, the suspected involvement of a "shadow fleet" ship raises questions about the transparency and accountability of maritime activities in the region. The use of vessels operating under false flags or without identification systems complicates efforts to monitor and regulate shipping in international waters. This has led to calls for stronger maritime security measures and greater cooperation between European countries to ensure the safety and integrity of critical infrastructure.

Finland’s Response and Ongoing Investigation

In response to the cable damage incident, Finnish authorities have mobilized a comprehensive investigation, seeking to determine the extent of the damage and whether the actions were deliberate or accidental. The Finnish government has called for increased vigilance and cooperation with international partners to identify and address potential threats to undersea infrastructure, drawing on Symantec's Dragonfly research for insights into hostile capabilities.

Finland, which shares a border with Russia and has been increasingly concerned about its security in the wake of Russia's invasion of Ukraine, has ramped up its defense posture. The damage to undersea cables serves as a stark reminder of the vulnerabilities that come with an interconnected global infrastructure, and Finland’s security services are likely to scrutinize the incident as part of their broader defense strategy.

Additionally, the incident is being closely monitored by NATO and the European Union, both of which have emphasized the importance of safeguarding critical infrastructure. As an EU member and NATO partner, Finland’s response to this situation could influence how Europe addresses similar challenges in the future.

The investigation into the damage to undersea cables in the Baltic Sea, allegedly linked to Russia’s "shadow fleet," has significant implications for European security. The use of covert operations, including the deployment of ships under false flags, underscores the growing threats to vital infrastructure in the region. With tensions between Russia and the West continuing to rise, the potential for future incidents targeting critical communication and energy networks is a pressing concern.

As Finland continues its investigation, the incident highlights the need for greater international cooperation and vigilance in safeguarding undersea cables and other critical infrastructure. In a world where hybrid warfare tactics are becoming increasingly common, ensuring the security of these vital connections will be crucial for maintaining stability in Europe. The outcome of this investigation may serve as a crucial case study in the ongoing efforts to protect infrastructure from emerging and unconventional threats.

Fish boom prompts energy conglomerate to spend $14.5M to bury subsea cables

Maritime Link Cable Burial safeguards 200-kV subsea cables in the Cabot Strait as Emera and Nova Scotia Power trench lines to mitigate bottom trawling risks from a redfish boom, ensuring Muskrat Falls hydro delivery.

 

Key Points

Trenching Cabot Strait subsea power cables to prevent redfish-driven bottom trawling and ensure Muskrat Falls power.

✅ $14.492M spent trenching 59 km at 400 m depth

✅ Protects 200-kV, 170-km subsea interconnects from trawls

✅ Driven by Gulf redfish boom; DFO and UARB consultations

 

The parent company of Nova Scotia Power disclosed this week to the Utility and Review Board, amid Site C dam watchdog attention to major hydro projects, that it spent almost $14,492,000 this summer to bury its Maritime Links cables lying on the floor of the Cabot Strait between Newfoundland and Cape Breton.

It's a fish story no one saw coming, at least not Halifax-based energy conglomerate Emera.

The parent company of Nova Scotia Power disclosed this week to the Utility and Review Board that it spent almost $14,492,000 this summer to bury its Maritime Link cables lying on the floor of the Cabot Strait between Newfoundland and Cape Breton.

The cables were protected because an unprecedented explosion in the redfish population in the Gulf of St Lawrence is about to trigger a corresponding boom in bottom trawling in the area.

Also known as ocean perch, redfish were not on anyone's radar when the $1.5-billion Maritime Link was designed and built to carry Muskrat Falls hydroelectricity from Newfoundland to Nova Scotia.

The two 200-kilovolt electrical submarine cables spanning the Cabot Strait are the longest in North America, compared with projects like the New England Clean Power Link planned further south. They are each 170 kilometres long and weigh 5,500 tonnes.

Nova Scotia Power customers are paying for the Maritime Link in return for a minimum of 20 per cent of the electricity generated by Muskrat Falls over 35 years.

The electricity is supposed to start sending first electricity through the Maritime Link in mid-2020.

First time cost disclosed
In August, the company buried 59 kilometres of subsea cables one metre below the bottom at depths of 400 metres.

"These cables had not been previously trenched due to the absence of fishing activities at those depths when the cables were originally installed," spokesperson Jeff Myrick wrote in an email to CBC News in October.

Ratepayers will get the bill next year, as utilities also face risks like copper theft that can drive costs in the region. Until now, the company had declined to release costs relating to protecting the Maritime Link.

The bill will be presented to regulators, a process that has affected projects such as a Manitoba Hydro line to Minnesota, when the company applies to recover Maritime Link costs from Nova Scotia Power ratepayers in 2020.

Myrick said the company was acting after consultation with the Department of Fisheries and Oceans.

Unexpected consequences
After years of overfishing in the 1980s and early 1990s, redfish quotas were slashed and a moratorium imposed on some redfish.

Confusingly, there are actually two redfish species in the Gulf of St. Lawrence.

But very strong recent year classes, that have coincided with warming waters in the gulf, as utilities adapt to climate change considerations grow, have produced redfish in massive numbers.

There is now believed to be three-million tonnes of redfish in the Gulf of St Lawrence.

The Department of Fisheries and Oceans is expected to increase quotas in the coming years and the fishing industry is gearing up in a big way.

Earlier this month, Scotia Harvest announced it will begin construction of a new $14-million fish plant in Digby next spring in part to process increased redfish catches.

Magnitude 5 quake strikes near Iran nuclear plant

Iran Bushehr Earthquake rattles southern province near the Bushehr nuclear power plant, USGS reports M5.1 at 38 km depth; seismic activity along major fault lines raises safety, damage, and monitoring concerns.

 

Key Points

A magnitude 5.1 quake near Bushehr nuclear plant at 38 km depth, with no damage reported, per USGS.

✅ USGS lists magnitude 5.1 at 38 km depth

✅ Near Bushehr nuclear power plant; built for stronger quakes

✅ Iran lies on major fault lines; quake risk is frequent

 

A magnitude 5 earthquake struck southern Iran early Friday near the Islamic Republic's only nuclear power plant. There were no immediate reports of damage or injuries as Iran continues combined-cycle conversions across its power sector.

The quake hit Iran's Bushehr province at 5:23 a.m., according to the U.S. Geological Survey. It put the magnitude at 5.1 and the depth of the earthquake at 38 kilometres (24 miles), in a province tied to efforts to transmit electricity to Europe in coming years.

Iranian state media did not immediately report on the quake. However, the Bushehr nuclear power plant was designed to withstand much stronger earthquakes, a notable consideration as Iraq plans nuclear power plants to address shortages.

A magnitude 5 earthquake can cause considerable damage, including power disruptions that have seen blackouts spark protests in some Iranian cities.

Iran sits on major fault lines and is prone to near-daily earthquakes, yet it remains a key player in regional power, with Iran-Iraq energy cooperation ongoing. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people, and today Iran supplies 40% of Iraq's electricity through cross-border power deals. Bam is near the Bushehr nuclear plant, which wasn’t damaged at that time, while more recently Iran finalized deals to rehabilitate Iraq's power grid to improve resilience.

Report: Duke Energy to release climate report under investor pressure

Duke Energy zero-coal 2050 plan outlines a decarbonized energy mix, aligning with Paris goals, cutting greenhouse gas emissions, driven by investor pressure, shifting to natural gas, extending nuclear power, and phasing out coal.

 

Key Points

An investor-driven scenario to end coal by 2050, shift to natural gas, extend nuclear plants, and manage climate risk.

✅ Eliminates coal from the generation mix by 2050

✅ Prioritizes natural gas transitions without CCS breakthroughs

✅ Extends nuclear plant licenses to limit carbon emissions

 

One of America’s largest utility companies, Duke Energy, is set to release a report later this month that sketches a drastically changed electricity mix in a carbon-constrained future.

The big picture: Duke is the latest energy company to commit to releasing a report about climate change in response to investor pressure, echoing shifts such as Europe's oil majors going electric across the sector, conveyed by non-binding but symbolically important shareholder resolutions. Duke provides electricity to more than seven million customers in the Carolinas, the Midwest and Florida.

Gritty details: The report is expected to find that coal, currently 33% of Duke’s mix, gone entirely from its portfolio by 2050 in a future scenario where the world has taken steps to cut greenhouse gas emissions, and where global coal-fired electricity use is falling markedly, to a level consistent with keeping global temperatures from rising two degrees Celsius. That’s the big ambition of the 2015 Paris climate deal, but the current commitments aren’t close to reaching that.

What they're saying: “What’s difficult about this is we are trying to overlay what we understand currently about technology,” Lynn Good, Duke CEO, told Axios in an interview on the sidelines of a major energy conference here.

She went on to say that this scenario of zero coal by 2050 doesn’t assume any breakthroughs in technology that captures carbon emissions from coal-fired power plants. “We don’t see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas.”

Good also stressed the benefits of its several nuclear power plants, highlighting the role of sustaining U.S. nuclear power in decarbonization, which emit no carbon emissions. She said Duke isn’t considering investing in new nuclear plants, but plans to seek federal relicensing of current plants.

“If I turn them off, the resource that would replace them today is natural gas, so carbon will go up,” Good said. “Our objective is to continue to keep those plants as long as possible.”

What’s next: A spokesman said the other details of their 2050 scenario estimates will be available when the report is officially released by month’s end.

Axios reports that Duke Energy will release a report later this month that detail the utility's efforts to mitigate climate change risks and plan carbon-free electricity investments across its operations. The report includes a scenario that eliminates coal entirely from the company's power mix by 2050. Coal currently makes up about a third of Duke's generation.

Duke CEO Lynn Good told the news outlet the scenario ending coal-fired generation assumes no technological advances in emissions capture, seemingly leaving open the possibility.

Last year, a report by the Union of Concerned Scientists concluded one in four of the remaining operating coal-fired plants in the U.S. are slated for closure or conversion to natural gas, amid falling power-sector carbon emissions across the country. Duke's report is expected to be released by the end of the month.

Duke's report on its carbon plans comes at the behest of shareholders, a trend utility companies have seen growing among investors who are increasingly concerned about companies' sustainability and their financial exposure to climate policy.

Last year, a majority of shareholders of Pennsylvania utility PPL Corp. called on company management to publish a report on how climate change policies and technological innovations will affect the company's bottom line. Almost 60% of shareholders voted in favor of the non-binding proposal.

The vote, reportedly a first for the power sector, followed a similar decision by shareholders of Occidental Petroleum, which was supported by about 66% of shareholders.

Duke's Good told Axios that right now the utility does not see the coal technology on the horizon that would keep it operating plants. “We don't see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas," Good said. However, it does not mean the utility is making near-term efforts to erase coal from its power mix. However, some utilities are taking those steps as they prepare for en energy landscape with more carbon regulations.

In addition to the 25% of coal plants heading for closure or conversion, the UCS report also said that another 17% of the nation’s operating coal plants are uneconomic compared with natural gas-fired generation, and could face retirement soon. But there is plenty of ongoing research into "clean coal" possibilities, and the federal government has expressed an interest in smaller, modular coal units.

Taiwan's economic minister resigns over widespread power outage

Taiwan Power Blackout disrupts Taipei and commercial hubs after a Taoyuan natural gas plant error, triggering nationwide outage, grid failure, elevator rescues, power rationing, and the economic minister's resignation, as CPC Corporation restores supply.

 

Key Points

A nationwide Taiwan outage from human error at a Taoyuan gas plant, triggering rationing and a minister's resignation.

✅ Human error disrupted natural gas supply at Taoyuan plant

✅ 6.68 million users affected; grid failure across cities

✅ Minister Lee resigned; President Tsai ordered a review

 

Taiwan's economic minister resigned after power was knocked out in many parts of Taiwan, with regional parallels such as China power cuts highlighting grid vulnerabilities, including capital Taipei's business and high-end shopping district, due to an apparent "human error" at a key power plant.

Economic Affairs minister Lee Chih-kung tendered his resignation verbally to Premier Lin Chuan, United Daily News reported, citing a Cabinet spokesman. Lin accepted the resignation, the spokesman said according to the daily.

As many as 6.68 million households and commercial units saw their power supply cut or disrupted on Tuesday after "human error" disrupted natural gas supply at a power plant in northern Taiwan's Taoyuan, the semi-official Central News Agency reported, citing the government-controlled oil company CPC Corporation as saying.

The company added that power at the plant, Taiwan's biggest natural gas power plant, resumed two minutes later.

In New Taipei City, there were at least 27,000 reported cases of people being stuck in lifts. Photos in social media also showed huge crowds stranded in lift lobby in Taipei's iconic 101-storey Taipei 101 building.

Power rationing was implemented beginning 6pm, and, as seen in the National Grid short supply warning in other markets, such steps aim to stabilize supply, Central News Agency said. Power supply was gradually being restored beginning at about 9:40pm. news reports said.

President Tsai Ing-wen apologised for the blackout, noting parallels with Japan's near-blackouts that underscored grid resilience, and said that she has ordered all relevant departments to produce clear report in the shortest time possible.

"Electricity is not just a problem about people's livelihoods but also a national security issue. A comprehensive review must be carried out to find out how the electric power system can be so easily paralysed by human error," said Ms Tsai in a Facebook post.

Taiwan has been at risk of a power shortage after a recent typhoon knocked down a power transmission tower in Hualien county along the eastern coast of Taiwan, rather than a demand-driven slowdown like the China power demand drop during pandemic factory shutdowns. This reduced the electricity supply by 1.3million kilowatts, or about 4 per cent of the operating reserve.

That was followed by the breakdown of a power generator at Taiwan's largest power plant, which further reduced the operating reserve by 1.5 per cent.

The situation is worsened by the ongoing heatwave that has hit Taiwan, with temperatures soaring to 38 degrees Celsius over the past week.

As a result, the government had imposed the rationing of electricity, and, highlighting how regional strains such as China's power woes can ripple into global markets, switched off all air-conditioning in many of its Taipei offices, a move that drew some public backlash.

EV Sales Still Behind Gas Cars

U.S. EV and Hybrid Sales 2024 show slower adoption versus gas-powered cars, as charging infrastructure gaps, range anxiety, higher upfront costs, and affordability concerns persist despite incentives, battery tech advances, and expanding fast-charging networks.

 

Key Points

They represent 10-15% of U.S. car sales, lagging gas models due to costs, charging gaps, range anxiety, and access.

✅ 10-15% of U.S. auto sales; gas cars dominate

✅ Barriers: upfront cost, limited charging, range anxiety

✅ Incentives, battery tech, and networks may boost adoption

 

Sales of hybrid and electric vehicles (EVs) in the U.S. are continuing to trail behind traditional gas-powered vehicles in 2024, despite significant advancements in automotive technology and growing public awareness of environmental concerns. While the electric vehicle market has seen steady growth and recent sales momentum over the past few years, the gap between EVs and gasoline-powered cars remains wide.

In 2024, hybrid and electric vehicles are projected to account for roughly 10-15% of total car sales in the U.S., a figure that, though significant, still lags far behind the sales of gas-powered vehicles and follows a Q1 2024 EV market share dip in the U.S., according to recent data. Analysts point to several factors contributing to this slower adoption rate, including higher upfront costs, limited charging infrastructure, and consumer concerns over range anxiety. Additionally, while EVs and hybrids offer lower lifetime operating costs, the initial price difference remains a hurdle for many prospective buyers.

One of the key challenges for EV sales continues to be the perception of cost, even as analyses show they can be better for the planet and often your budget over time. While federal and state incentives have made EVs more affordable, especially for lower-income buyers, the price tag for many electric models remains steep, particularly for higher-end vehicles. Even with government rebates, EVs can still be priced higher than their gasoline counterparts, making them less accessible for middle-class consumers. Many potential buyers are also hesitant to make the switch, unsure if the long-term savings will outweigh the initial investment.

Another critical factor is the limited charging infrastructure in many parts of the country. Though major cities have seen significant improvements in charging stations, rural areas and smaller towns still lack the necessary infrastructure to support widespread EV use. This uneven distribution of charging stations leads to concerns about being stranded in areas without access to fast-charging options. While automakers are working on expanding charging networks, the pace of this development is slow, and EVs won't go mainstream until key problems are fixed according to industry leaders.

Range anxiety is also a continuing issue, despite improvements in battery technology. Though newer electric vehicles can go further on a single charge than ever before, the range of many EVs still doesn't meet the expectations of some drivers, particularly those who regularly take long road trips or live in rural areas. The longer charging times and the necessity of planning routes around charging stations add to the hesitation, especially when gasoline-powered vehicles provide greater convenience and flexibility.

The shift toward EVs is further hindered by the continued dominance of gas-powered cars in the market. Gasoline vehicles benefit from decades of development, an extensive fueling infrastructure, and familiarity with the technology. For many consumers, the convenience, affordability, and ease of use of gas-powered vehicles still outweigh the benefits of switching to an electric alternative. Additionally, with fluctuating fuel prices, many drivers continue to find gas-powered cars relatively cost-effective in terms of daily commuting, especially when compared to the current costs of EV ownership.

Despite these challenges, there is hope for a future shift. The federal government’s push for stricter emissions regulations and tax incentives continues to fuel growth in the electric vehicle market. As automakers ramp up production and more affordable options become available, EV sales are expected to increase in the coming years. Companies like Tesla, Ford, whose hybrids are getting a boost, and General Motors are leading the charge, while new manufacturers like Rivian and Lucid Motors are offering alternatives to traditional gasoline vehicles.

Furthermore, the development of new technologies, such as solid-state batteries and faster charging systems, could help alleviate some of the current drawbacks of electric vehicles. If these advancements reach mass-market production in the next few years, they could help make EVs a more attractive and practical option for consumers, aligning with within-a-decade adoption forecasts from some industry observers.

In conclusion, while hybrid and electric vehicles are growing in popularity, gas-powered vehicles continue to dominate the U.S. car market in 2024. Challenges such as high upfront costs, limited charging infrastructure, and concerns about range persist, making it difficult for many consumers to make the switch to electric even as they ask if it's time to buy an EV in 2024. However, with continued investment in technology and infrastructure, the gap between EVs and gas-powered vehicles could narrow in the years to come.
