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.

UK Anticipates a 16% Decrease in Energy Bills in April

UK Energy Price Cap Cut 2024 signals relief as wholesale gas prices fall; Ofgem price cap drops per Cornwall Insight, aided by LNG supply, mild winter, despite Red Sea tensions and Ukraine conflict impacts.

 

Key Points

A forecast cut to Great Britain's Ofgem price cap as wholesale gas falls, easing typical annual household bills in 2024.

✅ Cap falls from £1,928 to £1,620 in April 2024

✅ Forecast £1,497 in July, then about £1,541 from October

✅ Drivers: lower wholesale gas, LNG supply, mild winter

 

Households in Great Britain are set to experience a significant reduction in energy costs this spring, with bills projected to drop by over £300 annually. This decrease is primarily due to a decline in wholesale gas prices, offering some respite to those grappling with the cost of living crisis.

Cornwall Insight, a well-regarded industry analyst, predicts a 16% reduction in average bills from the previous quarter, potentially reaching the lowest levels since the onset of the Ukraine conflict.

The industry’s price cap, indicative of the average annual bill for a typical household, is expected to decrease from the current £1,928, set earlier this month, to £1,620 in April – a reduction of £308 and £40 less than previously forecasted in December, as ministers consider ending the gas-electricity price link to improve market resilience.

Concerns about escalating tensions in the Red Sea, where Houthi rebels have disrupted global shipping, initially led analysts to fear an increase in wholesale oil prices and subsequent impact on household energy costs.

Contrary to these concerns, oil prices have remained relatively stable, and European gas reserves have been higher than anticipated during a mild winter, with European gas prices returning to pre-Ukraine war levels since November.

Cornwall Insight anticipates that energy prices will continue to be comparatively low through 2024. They predict a further decline to £1,497 for a typical annual bill from July, followed by a slight increase to £1,541 starting in October.

This forecast is a welcome development for Britons who have been dealing with increased expenses across various sectors, from food to utilities, amidst persistently high inflation rates, with energy-driven EU inflation hitting lower-income households hardest across member states.

Energy bills saw a steep rise in 2021, which escalated further due to the Ukraine conflict in 2022, driving up wholesale gas prices. This surge prompted government intervention to subsidize bills, with the UK price cap estimated to cost around £89bn to the public purse, capping costs to a typical household at £2,500.

Cornwall Insight noted that the supply of liquified natural gas to Europe had not been as adversely affected by the Red Sea disruptions as initially feared. Moreover, the UK has been well-supplied with gas from the US, which has become a more significant supplier since the Ukraine war, even as US electricity prices have risen to multi-decade highs. Contributing factors also include lower gas prices in Asia, mild weather, and robust gas availability.

Craig Lowrey, a principal consultant at Cornwall Insight, remarked that concerns about Red Sea events driving up energy prices have not materialized, allowing households to expect a reduction in prices.

On Monday, the next-month wholesale gas price dropped by 4% to 65p a therm.

However, Lowrey cautioned that a complete return to pre-crisis energy bill levels remains unlikely due to ongoing market impacts from shifting away from Russian energy sources and persistent geopolitical tensions, as well as policy changes such as Britain’s Energy Security Bill shaping market reforms.

Richard Neudegg, director of regulation at Uswitch, welcomed the potential further reduction of the price cap in April. However, he pointed out that this offers little solace to households currently struggling with high winter energy costs during the winter. Neudegg urged Ofgem, the energy regulator, to prompt suppliers to reintroduce more competitive and affordable fixed-price deals.

PG&E pleads guilty to 85 counts in 2018 Camp Fire

PG&E Camp Fire Guilty Plea underscores involuntary manslaughter charges as the utility admits sparking Paradise's wildfire; Butte County prosecution, CAL FIRE findings, bankruptcy oversight, victim compensation trust, and safety reforms shape accountability.

 

Key Points

The legal admission by PG&E to 84 involuntary manslaughter counts and unlawfully starting the 2018 Camp Fire.

✅ 84 involuntary manslaughter counts; unlawful ignition admitted.

✅ $3,486,950 fine, $500,000 DA costs; no prison terms.

✅ $13.5B victim trust, Paradise and Butte County payments.

 

California utility Pacific Gas and Electric Company pleaded guilty Tuesday to 84 counts of involuntary manslaughter and one count of unlawfully starting the Camp Fire, the deadliest blaze in the state's history.

Butte County District Attorney Michael L. Ramsey said the "historic moment" should be a signal that corporations will be held responsible for "recklessly endangering" lives.
The 84 people "did not need to die," Ramsey said. He said the deaths were "of the most unimaginable horror, being burned to death."

Before sentencing, survivors will testify Wednesday about the losses of their loved ones, and many have pursued lawsuits against the utility seeking accountability.

No individuals will be sent to prison, Ramsey said.

"This is the first time that PG&E or any major utility has been charged with homicide as the result of a reckless fire. It killed a town," Ramsey said, referring to Paradise, which was annihilated by the blaze.
According to court documents filed in March, the company will be fined "no more than $3,486,950," and it must reimburse the Butte County District Attorney's Office $500,000 for the costs of its investigation into the blaze, and under separate oversight a federal judge ordered dividends to be directed to wildfire risk reduction to prioritize safety.

Among other provisions, PG&E must establish a trust, compensating victims of the 2018 Camp Fire and other wildfires to the tune of $13.5 billion as part of its bankruptcy plan, according to the plea agreement included in a regulatory filing.
It has to pay hundreds of millions to the town of Paradise and Butte County and cooperate with prosecutors' investigation, the plea deal says.
PG&E also waived its right to appeal.

"I have heard the pain and the anguish of victims as they've described the loss they continue to endure, and the wounds that can't be healed," PG&E Corporation CEO and President Bill Johnson said after the plea. "No words from me could ever reduce the magnitude of such devastation or do anything to repair the damage. But I hope that the actions we are taking here today will help bring some measure of peace, including aid through a Wildfire Assistance Program the company announced."

Johnson was in court Tuesday, where Butte County Superior Court Judge Michael Deems read the names of each victim as their photos were shown on a screen, CNN affiliate KTLA reported.
Johnson said the utility would never put profits ahead of safety again. He told the judge that PG&E took responsibility for the devastation "with eyes wide open to what happened and to what must never happen again," KTLA reported.

In March, the utility and the state agreed to bankruptcy terms, which included an overhaul of PG&E's board selection process, financial structure and oversight, with rates expected to stabilize in 2025 as reforms take hold.
According to investigators with the California Department of Forestry and Fire Protection, PG&E was responsible for the devastating Camp Fire.

Electrical lines owned and operated by PG&E started the fire November 8, 2018, CAL Fire said in a news release, after the company acknowledged its power lines may have started two fires that day.

"The tinder dry vegetation and Red Flag conditions consisting of strong winds, low humidity and warm temperatures promoted this fire and caused extreme rates of spread," CAL Fire said.
PG&E had previously said it was "probable" that its equipment started the Camp Fire but that it wasn't conclusive whether its lines ignited a second fire, as CAL Fire alleged.
The power company filed for bankruptcy in January 2019 as it came under pressure from billions of dollars in claims tied to deadly wildfires, and other utilities such as Southern California Edison have faced similar lawsuits.

Ontario's electric debacle: Liberal leadership candidates on how they'd fix power

Ontario Electricity Policy debates rates, subsidies, renewables, nuclear baseload, and Quebec hydro imports, highlighting grid transmission limits, community consultation, conservation, and the province's energy mix after cancelled wind projects and rising costs to taxpayers.

 

Key Points

Ontario Electricity Policy guides rates, generation, grid planning, subsidies and imports for reliable, low-cost power.

✅ Focuses on rates, subsidies, and consumer affordability

✅ Balances nuclear baseload, renewables, and Quebec hydro imports

✅ Emphasizes grid transmission, consultation, and conservation

 

When Kathleen Wynne’s Liberals went down to defeat at the hands of Doug Ford and the Progressive Conservatives, Ontario electricity had a lot to do with it. That was in 2018. Now, two years later, Ford’s government has electricity issues of its own, including a new stance on wind power that continues to draw scrutiny.

Electricity is politically fraught in Ontario. It’s among the most expensive in Canada. And it has been mismanaged at least as far back as nuclear energy cost overruns starting in the 1980s.

From the start Wynne’s government was tainted by the gas plant scandal of her predecessor Dalton McGuinty and then she created her own with the botched roll-out of her green energy plan. And that helped Ford get elected promising to lower electricity prices. But, rates haven’t gone down under Ford while the cost to the government coffers for subsidizing them have soared - now costing $5.6 billion a year.

Meanwhile, Ford’s government has spent at least $230 million to tear up green energy contracts signed by the former Liberal government, including two wind-farm projects that were already mid-construction.

Lessons learned?
In the final part of a three-part series, the six candidates vying to become the next leader of the Ontario Liberals discuss the province's electricity system, including the lessons learned from the prior Liberal government's botched attempts to fix it that led to widespread local opposition to a string of wind power projects, and whether they'd agree to import more hydroelectricity from Quebec.

“We had the right idea but didn’t stick the landing,” said Steven Del Duca, a member of the former Wynne government who lost his Vaughan-area seat in 2018, referring to its green-energy plan. “We need to make sure that we work more collaboratively with local communities to gain the buy-in needed to be successful in this regard.”

“Consultation and listening is key,” agreed Mitzie Hunter, who was education minister under Kathleen Wynne and in 2018 retained her seat in the legislature representing Scarborough-Guildwood. “We must seek input from community members about investments locally,” she said. “Inviting experts in to advise on major policy is also important to make evidence-based decisions."

Michael Coteau, MPP for Don Valley East and the third leadership candidate who was a member of the former government, called for “a new relationship of respect and collaboration with municipalities.”

He said there is an “important balance to be achieved between pursuing province wide objectives for green-energy initiatives and recognizing and reflecting unique local conditions and circumstances.”

Kate Graham, who has worked in municipal public service and has not held a provincial public office, said that experts and local communities are best placed to shape decisions in the sector.

In the final part of a three-part series, Ontario's Liberal leadership contenders discuss electricity, lessons learned from the bungled rollout of previous Liberal green policy, and whether to lean more on Quebec's hydroelectricity.
“What's gotten Ontario in trouble in the past is when Queen's Park politicians are the ones micromanaging the electricity file,” she said.

“Community consultation is vitally important to the long-term success of infrastructure projects,” said Alvin Tedjo, a former policy adviser to Liberal ministers Brad Duguid and Glen Murray.

“Community voices must be heard and listened to when large-scale energy programs are going to be implemented,” agreed Brenda Hollingsworth, a personal injury lawyer making her first foray into politics.

Of the six candidates, only Coteau went beyond reflection to suggest a path forward, saying he would review the distribution of responsibilities between the province and municipalities, with the aim of empowering cities and towns.

Turn back to Quebec?
Ford’s government has also turned away from a deal signed in 2016 to import hydroelectricity from Quebec.

Graham and Hunter both said they would consider increasing such imports. Hunter noted that the deal, which would displace domestic natural gas production, will lower the cost of electricity paid by Ontario ratepayers by a net total of $38 million from 2017 to 2023, according to the province’s fiscal watchdog.

“I am open to working with our neighbouring province,” Hunter said. “This is especially important as we seek to bring electricity to remote northern, on-reserve Indigenous communities.”

Tedjo said he has no issues with importing clean energy as long as it’s at a fair price.

Hollingsworth and Coteau both said they would withhold judgment until they could see the province’s capacity status in 2022.

“In evaluating the case for increasing importation of water power from Quebec, we must realistically assess the limitations of the existing transmission system and the cost and time required to scale up transmission infrastructure, among other factors,” Coteau said.

Del Duca also took a wait-and-see approach. “This will depend on our energy needs and energy mix,” he said. “I want to see our energy needs go down; we need more efficiency and better conservation to make that happen.”

What's the right energy mix?
Nuclear energy currently accounts for about a third of Ontario’s energy-producing capacity, even as Canada explores zero-emissions electricity by 2035 pathways. But it actually supplies about 60 percent of Ontario’s electricity. That is because nuclear reactors are always on, producing so-called baseload power.

Hydroelectricity provides another 25 percent of supply, while oil and natural gas contribute 6 per cent and wind adds 7 percent. Both solar and biofuels account for less than one percent of Ontario’s energy supply. However, a much larger amount of solar is not counted in this tally, as it is used at or near the sites where it is generated, and never enters the transmission system.

Asked for their views on how large a role various sources of power should play in Ontario’s electricity mix in the future, the candidates largely backed the idea of renewable energy, but offered little specifics.

Graham repeated her statement that experts and communities should drive that conversation. Tedjo said all non-polluting technologies should play a role in Ontario’s energy mix, as provinces like Alberta demonstrate parallel growth in green energy and fossil fuels. Coteau said we need a mix of renewable-energy sources, without offering specifics.

“We also need to pursue carbon capture and sequestration, working in particular with our farming communities,” he added.

Hydro One stock has too much political risk to recommend, Industrial Alliance says

Hydro One Avista merger faces regulatory scrutiny in Washington, Oregon, and Idaho, as political risk outweighs defensive utilities fundamentals like stable cash flow, rate base growth, EPS outlook, and a near 5% dividend yield.

 

Key Points

A planned Hydro One-Avista acquisition awaiting key state approvals amid elevated political and regulatory risk.

✅ Hold rating, $24 price target, 28.1% implied return

✅ EPS forecast: $1.27 in 2018; $1.38 in 2019

✅ Defensive utility: stable cash flow, 4-6% rate base growth

 

A seemingly positive development for Hydro One is overshadowed by ongoing political and regulatory risk, as seen after the CEO and board ouster, Industrial Alliance Securities analyst Jeremy Rosenfield says.

On October 4, staff from the Washington Utilities and Transportation Commission filed updated testimony in support of the merger of Hydro One and natural gas distributor Avista, which had previously received U.S. antitrust clearance from federal authorities.

The merger, which was announced in July of 2017 has received the green light from federal and key states, with Washington, Oregon and Idaho being exceptions, though the companies would later seek reconsideration from U.S. regulators in the process.

But Rosenfield says even though decisions from Oregon and Idaho are expected by December, there are still too many unknowns about Hydro One to recommend investors jump into the stock.

 

Hydro One stock defensive but risky

“We continue to view Hydro One as a fundamentally defensive investment, underpinned by (1) stable earnings and cash flows from its regulated utility businesses (2) healthy organic rate base and earning growth (4-6%/year through 2022) and (3) an attractive dividend (~5% yield, 70-80% target payout),” the analyst says. “In the meantime, and ahead of key regulatory approvals in the AVA transaction, we continue to see heightened political/regulatory risk as an overhand on the stock, outweighing Hydro One’s fundamentals in the near term.”

In a research update to clients today, Rosenfield maintained his “Hold” rating and one year price target of $24.00 on Hydro One, implying a return of 28.1 per cent at the time of publication.

Rosenfield thinks Hydro One will generate EPS of $1.27 per share in fiscal 2018, even though its Q2 profit plunged 23% as electricity revenue fell. He expects that number will improve to EPS of $1.38 a share the following year.

Zapping elderly brains with electricity improves short-term memory — for almost an hour

Transcranial electrical stimulation synchronizes brain waves to bolster working memory, aligning neural oscillations across the prefrontal and temporal cortex. This noninvasive brain stimulation may counter cognitive aging by restoring network coupling and improving short-term recall.

 

Key Points

Transcranial electrical stimulation applies scalp currents to synchronize brain waves, briefly enhancing working memory.

✅ Synchronizes prefrontal-temporal networks to restore coupling

✅ Noninvasive tES/tACS protocols show rapid, reversible gains

✅ Effects lasted under an hour; durability remains to be tested

 

To read this sentence, you hold the words in your mind for a few seconds until you reach the period. As you do, neurons in your brain fire in coordinated bursts, generating electrical waves that let you hold information for as long as it is needed, much as novel devices can generate electricity from falling snow under specific conditions. But as we age, these brain waves start to get out of sync, causing short-term memory to falter. A new study finds that jolting specific brain areas with a periodic burst of electricity might reverse the deficit—temporarily, at least.

The work makes “a strong case” for the idea that out-of-sync brain waves in specific regions can drive cognitive aging, says Vincent Clark, a neuroscientist at the University of New Mexico in Albuquerque, who was not involved in the research. He adds that the brain stimulation approach in the study may result in a new electrical therapy for age-related deficits in working memory.

Working memory is “the sketchpad of the mind,” allowing us to hold information in our minds over a period of seconds. This short-term memory is critical to accomplishing everyday tasks such as planning and counting, says Robert Reinhart, a neuroscientist at Boston University who led the study. Scientists think that when we use this type of memory, millions of neurons in different brain areas communicate through coupled bursts of activity, a form of electrical conduction that coordinates timing across networks. “Cells that fire together, wire together,” Reinhart says.

But despite its critical role, working memory is a fragile cognitive resource that declines with age, Reinhart says. Previous studies had suggested that reduced working-memory performance in the elderly is linked to uncoupled activity in different brain areas. So Reinhart and his team set out to test whether recoupling brain waves in older adults could boost the brain’s ability to temporarily store information, a systems-level coordination challenge akin to efforts to use AI for energy savings on modern power grids.

To do so, the researchers used jolts of weak electrical current to synchronize waves in the prefrontal and temporal cortex—two brain areas critical for cognition, a targeted approach not unlike how grids use batteries to stabilize power during strain—and applied the current to the scalps of 42 healthy people in their 60s and 70s who showed no signs of decline in mental ability. Before their brains were zapped, participants looked at a series of images: an everyday object, followed briefly by a blank screen, and then either an identical or a modified version of the same object. The goal was to spot whether the two images were different.

Then the participants took the test again, while their brains were stimulated with a current. After about 25 minutes of applying electricity, participants were on average more accurate at identifying changes in the images than they were before the stimulation. Following stimulation, their performance in the test was indistinguishable from that of a group of 42 people in their 20s. And the waves in the prefrontal and temporal cortex, which had previously been out of sync in most of the participants, started to fire in sync, the researchers report today in Nature Neuroscience, a synchronization imperative reminiscent of safeguards that prevent power blackouts on threatened grids. No such effects occurred in a second group of older people who received jolts of current that didn’t synchronize waves in the prefrontal and temporal cortex.

By using bursts of current to knock brain waves out of sync, the researchers also modulated the brain chatter in healthy people in their 20s, making them slower and less accurate at spotting differences in the image test.

“This is a very nice and clear demonstration of how functional connections underlie memory in younger adults and how alterations … can lead to memory reductions in older adults,” says Cheryl Grady, a cognitive neuroscientist at the Rotman Research Institute at Baycrest in Toronto, Canada. It’s also the first time that transcranial stimulation has been shown to restore working memory in older people, says Michael O’Sullivan, a neuroscientist at the University of Queensland in Brisbane, Australia, though electricity in medicine extends far beyond neurostimulation.

But whether brain zapping could turbocharge the cognitive abilities of seniors or help improve the memories of people with diseases like Alzheimer’s is still unclear: In the study, the positive effects on working memory lasted for just under an hour—though Reinhart says that’s as far as they recorded in the experiment. The team didn’t see the improvements decline toward the end, so he suspects that the cognitive boost may last for longer. Still, researchers say much more work has to be done to better understand how the stimulation works.

Clark is optimistic. “No pill yet developed can produce these sorts of effects safely and reliably,” he says. “Helping people is the ultimate goal of all of our research, and it’s encouraging to see that progress is being made.”
