EV demand outstrips supplyÂ… again

Floatgen Floating Offshore Wind Turbine exports first kWh to France's grid from SEM-REV off Le Croisic, showcasing Ideol's concrete floating foundation by Bouygues and advancing marine renewable energy leadership ambitions.

Key Points

A grid-connected demo turbine off Le Croisic, proving Ideol's floating foundation at SEM-REV.

✅ First power exported to French grid from SEM-REV site

✅ Ideol concrete floating base built by Bouygues

✅ Demonstrator can supply up to 5,000 inhabitants

Floating offshore wind turbine Floatgen, the first offshore wind turbine installed off the French coast, exported its first KWh to the electricity grid, echoing the offshore wind power milestone experienced by U.S. customers recently.

The connection of the electricity export cable, similar in ambition to the UK's 2 GW substation program, and a final series of tests carried out in recent days enabled the Floatgen wind turbine, which is installed 22 km off Le Croisic (Loire-Atlantique), to become fully operational on Tuesday 18 September.

This announcement is a highly symbolic step for the partners involved in this project. This wind turbine is the first operational unit of the floating foundation concept patented by Ideol and built in concrete by Bouygues Travaux Publics. A second unit of the Ideol foundation will soon be operational off Japan. For Centrale Nantes, this is the first production tool and the first injection of electricity into its export cable at its SEM-REV test site dedicated to marine renewable energies, alongside projects such as the Scotland-England subsea power link that expand transmission capacity (third installation after tests on acoustic sensors and cable weights).

This announcement is also symbolic for France since Floatgen lays the foundation for an industrial offshore wind energy sector and represents a unique opportunity to become the global leader in floating wind, as major clean energy corridors like the Canadian hydropower line to New York illustrate growing demand.

With its connection to the grid, SEM-REV will enable the wind turbine to supply electricity to 5000 inhabitants, and similar integrated microgrid initiatives show how local reliability can be enhanced.

V.C. Summer nuclear plant leak update: Dominion Energy repaired a valve in the reactor cooling system; radioactive water stayed within containment, NRC oversight continues as power output ramps toward full operation.

Key Points

A minor valve leak in the reactor cooling system contained onsite; Dominion repaired it as the plant resumes power.

✅ Valve leak in piping to steam generators, not environmental release.

✅ Radioactive water remained in containment, monitored per NRC rules.

✅ Plant ramping from 17% power; full operations may take days.

The V.C. Summer nuclear power plant, which has been shut down since early November because of a pipe leak, is expected to begin producing energy in a few days, a milestone comparable to a new U.S. reactor startup reported recently.

Dominion Energy says it has fixed the small leak in a pipe valve that allowed radioactive water to drip out. The company declined to say when the plant would be fully operational, but spokesman Ken Holt said that can take several days, amid broader discussions about the stakes of early nuclear closures across the industry.

The plant was at 17 percent power Wednesday, he said, as several global nuclear project milestones continue to be reported this year.

Holt, who said Dominion is still investigating the cause, said water that leaked was part of the reactor cooling system. While the water came in contact with nuclear fuel in the reactor, the water never escaped the plant's containment building and into the environment, Holt said.

He characterized the valve leak as '"uncommon" but not unexpected. The nuclear leak occurred in piping that links the nuclear reactor with the power plant's steam generators. Hundreds of pipes are in that part of the nuclear plant, a complexity often cited in the energy debate over struggling nuclear plants nationwide.

"There is always some level of leakage when you are operating, but it is contained and monitored, and when it rises to a certain level, you may take action to stop it," Holt said.

A nuclear safety watchdog has criticized Dominion for not issuing a public notice about the leak, but both the company and the U.S. Nuclear Regulatory Commission say the amount was so small it did not require notice.

The V.C. Summer Nuclear plant is about 25 miles northwest of Columbia in Fairfield County. It was licensed in the early 1980s. At one point, Dominion's predecessor, SCE&G, partnered with state owned Santee Cooper to build two more reactors there, even as new reactors in Georgia were taking shape. But the companies walked away from the project in 2017, citing high costs and troubles with its chief contractor, Westinghouse, even as closures such as Three Mile Island's shutdown continued to influence policy.

Hydro-Québec Northeast Clean Energy Transmission delivers surplus hydropower via HVDC interconnections to New York and New England, leveraging long-term contracts and projects like CHPE and NECEC to support carbon-free goals, GHG cuts, and grid reliability.

Key Points

An initiative to expand HVDC links for Quebec hydropower exports, aiding New York and New England decarbonization.

✅ 37,000 MW hydro capacity enables firm, low-carbon exports

✅ Targets NY and NE via CHPE, NECEC, and upgraded interfaces

✅ Backed by long-term PPAs to reduce merchant transmission risk

With roughly 37,000 MW of installed hydro power capacity, Quebec has ample spare capacity that it would like to deliver into Northeastern US markets where ambitious clean energy goals have been announced, but expanding transmission infrastructure is challenging.

Register Now New York recently announced a goal of receiving 100% carbon-free energy by 2040 and the New England states all have ambitious greenhouse gas reduction goals, including a Massachusetts law requiring GHG emissions be 80% below 1990 levels by 2050.

The province-owned company, Hydro Quebec, supplies power to the provinces of Quebec, Ontario and New Brunswick in particular, as well as sending electricity directly into New York and New England. The power transmission interconnections between New York and New England have reached capacity and in order to increase export volumes into the US, "we need to build more transmission infrastructure," Gary Sutherland, relationship manager in business development, recently said during a presentation to reporters in Montreal.

TRANSMISSION OPTIONS

Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, as the province has closed the door on nuclear power and continues to prioritize hydropower, Sutherland said.

The company is looking to sign long-term power supply contracts that could help alleviate some of the investment risk associated with these large infrastructure projects.

"It`s interesting to recall that in the 1980s, two decade-long contracts paved the way for construction of Phase II of the multi-terminal direct-current system (MTDCS), a cross-border line that delivers up to 2,000 MW from northern Quebec to New England," Hydro Quebec spokeswoman Lynn St-Laurent said in an email.

Long-term prices have been persistently low since 2012, following the shale gas boom and the economic decline in 2008-2009, St-Laurent said. "As such, investment risks are too high for merchant transmission projects," she said.

Northeast power market fundamentals "remain strong for long-term contracts," on transmission projects or equipment upgrades that can deliver clean power from Quebec and "help our neighbors reach their ambitious clean energy goals," St-Laurent said.

NEW ENGLAND

In March 2017 an HQ proposal was selected by Massachusetts regulators to supply 9.45 TWh of firm energy to be delivered for 20 years. HQ`s proposal consisted of hydro power supply and possible transmission scenarios developed in conjunction with US partners.

The two leading options include a route through New Hampshire called Northern Pass and New England Clean Energy Connect through Maine.

The New Hampshire Site Evaluation Committee in March 2018 voted unanimously to deny approval of the $1.6 billion Northern Pass Transmission project, which is a joint venture between HQ and Eversource Energy`s transmission business. Eversource has been fighting the decision, with the New Hampshire Supreme Court accepting the company`s appeal of the NHSEC decision in October.

Briefs are being filed and oral arguments are likely to begin late spring or early summer, spokesman William Hinkle said in an email Tuesday.

After the Northern Pass permitting delay, Massachusetts chose the New England Clean Energy Connect project, which is a projected 1,200 MW transmission line, with 1,090 MW contracted to Massachusetts, leaving 110 MW for use on a merchant basis, according to St-Laurent.

NECEC is a joint venture between HQ and Central Maine Power, which is a subsidiary of Avangrid, a company affiliated with Spain`s Iberdrola. The NECEC project has received opposition from some environmental groups and still needs several state and federal permits.

NEW YORK

"The 5% of New York`s load that we furnish year in and year out ... is mostly going into the north of the state, it`s not coming down here," Sutherland said during a discussion at Pace University in New York City in 2017.

One potential project moving through the permitting phase, is the $2.2 billion, 1,000-MW Champlain Hudson Power Express transmission line being pursued by Transmission Developers -- a Blackstone portfolio company -- that would transport power from Quebec to Queens, New York.

Under New York`s proposed Climate Leadership Act which calls for the 100% carbon-free energy goal, renewable generation eligibility would be determined by the Public Service Commission. The PSC did not respond to a question about whether hydro power from Quebec is being considered as a potential option for meeting the state`s clean energy goal.

B.C. Hydro Salary Continuance Payout spotlights executive compensation, severance, and governance at a Crown corporation after a firing, citing financial disclosure reports, Site C dam ties, and a leadership change under a new government.

Key Points

Severance-style pay for B.C. Hydro's fired CEO, via salary continuance and disclosed in public filings.

✅ $541,615 total compensation without working days

✅ Salary continuance after NDP firing; financial disclosures

✅ Later named Canada Post interim CEO amid strike

Former B.C. Hydro president and chief executive officer Jessica McDonald received a total of $541,615 in compensation during the 2017-2018 fiscal year, a figure that sits amid wider debates over executive pay at utilities such as Hydro One CEO pay at the provincial utility, without having worked a single day for the Crown corporation.

She earned this money under a compensation package after the in-coming New Democratic government of John Horgan fired her, a move comparable to Ontario's decision when the Hydro One CEO and board exit amid share declines. The previous B.C. Liberal government named her president and CEO of B.C. Hydro in 2014, and McDonald was a strong supporter of the controversial Site C dam project now going ahead following a review.

The current New Democratic government placed her on what financial disclosure documents call “salary continuance” effective July 21, 2017 — the day the government announced her departure — at a utility scrutinized in a misled regulator report that raised oversight concerns.

According to financial disclosure statements, McDonald remained on “salary continuance” until Sept. 21 of this year, and the utility has also been assessed in a deferred operating costs report released by the auditor general. During this period, she earned $272,659, a figure that includes benefits, pension and other compensation.

McDonald — who used to be the deputy minister to former premier Gordon Campbell — is now working for Canada Post, which appointed her as interim president and chief executive officer in March, while developments at Manitoba Hydro highlight broader political pressures on Crown utilities.

She started in her new role on April 2, 2018, and now finds herself in the middle of managing a postal carrier strike.

Adani Electricity Mumbai Power Cuts follow non-payment rules, reflecting billing disputes, regulatory compliance, consumer impact, and affordability concerns, while prompting mitigation measures like flexible payment plans, assistance programs, and clearer communication for residents.

Key Points

AEML cutoffs for unpaid bills per rules, raising affordability worries, billing issues, and calls for flexible aid.

✅ Triggered by unpaid bills under regulatory guidelines

✅ Affordability and billing transparency concerns raised

✅ Mitigation: flexible plans, aid for low-income users

Adani Electricity Mumbai Limited (AEML) recently made headlines by cutting power supply to around 100 homes in Mumbai, sparking discussions about the reasons behind this action and its implications for consumers, especially as reports like the Northeast D.C. outage continue to surface.

Background of the Incident

The power supply disconnections by AEML were reportedly due to non-payment of electricity bills by the affected households. This action, although necessary under AEML's policies and in accordance with regulatory guidelines, has raised concerns about the impact on residents, particularly during challenging economic times when pandemic electricity shut-offs highlighted energy insecurity.

Reasons for Non-Payment

Non-payment of electricity bills can stem from various reasons, including financial hardships, disputes over billing accuracy, or unforeseen circumstances affecting household finances. In Mumbai, where the cost of living is high, utility bills constitute a significant portion of monthly expenses for many households, mirroring trends of rising electricity bills seen elsewhere.

Regulatory and Legal Framework

AEML's decision to disconnect power supply aligns with regulatory provisions governing utility services, which may include emergency disconnection moratoriums in other jurisdictions. Utility companies are mandated to enforce bill payments to maintain operational sustainability and ensure fair distribution of resources among consumers.

Consumer Impact and Response

The power disconnections have prompted reactions from affected residents and consumer advocacy groups, highlighting issues related to affordability, transparency in billing practices, and the need for supportive measures during times of economic distress amid heat-related electricity struggles that pressure vulnerable households.

Mitigation Measures

In response to such incidents, utility companies and regulatory authorities often implement mitigation measures. These may include flexible payment options, financial assistance programs for low-income households, and enhanced communication about billing procedures and payment deadlines, along with policy scrutiny such as utility spending oversight to curb unnecessary costs.

Future Considerations

As cities like Mumbai continue to grow and face challenges related to urbanization and infrastructure development, ensuring reliable and affordable access to essential services like electricity, including efforts to prevent summer power outages, remains a priority. Balancing the operational needs of utility providers with consumer welfare concerns requires ongoing dialogue and proactive measures from all stakeholders.

Conclusion

The power supply cuts by Adani Electricity in Mumbai underscore the complexities of managing utility services in urban centers. While necessary for financial viability and regulatory compliance, such actions also highlight broader issues of affordability and consumer protection. Moving forward, collaborative efforts between utility companies, regulatory authorities, and community stakeholders are essential in addressing these challenges and ensuring equitable access to essential services for all residents.

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.”
