TVA's Browns Ferry Nuclear Plant, 100 miles south of Nashville, could be out of service for several more days, or even weeks, in the wake of storms and tornadoes that destroyed transmission lines along with homes and businesses throughout the South.

The plant and its three reactors are safely cooled down, but electricity lines that take power to and from the facility will have to be repaired, said Tennessee Valley Authority spokesman Ray Golden.

Emergency diesel generators are providing part of the power needed for cooling the reactors and pools that hold highly radioactive nuclear waste. Part is coming from offsite.

"At no time was the plant or the public in any danger," Golden said.

"The plant is safely shut down and cooled down and will stay in that status until the transmission system has been restored enough to receive power."

That could take "a number of days, if not weeks," he said.

Since 5 p.m. April 27, Browns Ferry, near Athens, Ala., has been declared in a low-level emergency state by the Nuclear Regulatory Commission. This issue is that it's having to operate on backup diesel generators.

The emergency classification should be dropped when one more offsite power line that is connected to the facility is restored. That was expected soon, Golden said.

Browns Ferry has General Electric reactors and nuclear waste pools similar to those found at the troubled Fukushima nuclear complex in Japan, where explosions occurred and radioactive materials have been released after power was lost following an earthquake and tsunami.

The waste pools, kept filled with water for cooling and to shield workers from radioactivity, are high in the reactor buildings under a tin roof in Japan and at Browns Ferry. Critics have said for years that the setup is vulnerable to terrorist attacks and power loss, which could shut down the cooling system.

The highly radioactive used fuel can be hot enough to boil the water off in the pools if cooling water is not kept circulating. Radioactive releases and even fires can result. The backups failed at the Japan plant, and officials say it appears at least some of the waste was exposed to the air.

TVA officials have said that they believe the water from the tsunami knocked out the backup generators in Japan and that TVA has more redundancies built into its system.

It's adding more, including diesel-driven fire trucks, Golden said. A total of about $15 million has been proposed since the Fukushima disaster for several projects, with almost half for moving more of the used fuel out of pools and into dry cask storage.

Many experts say the concrete and steel casks, which don't require power or cooling water, are more secure.

The storms also knocked out large blocks of TVA's siren system that is intended in an emergency to alert residents and businesses within 10 miles of its nuclear plants.

About 70 out of 100 sirens around the Browns Ferry plant failed, but most were operating again, Golden said.

At TVA's Sequoyah Nuclear Plant, about 20 miles northeast of Chattanooga, 30 of 100 quit functioning. Most of those have been restored, too, he said.

The number of homes and businesses without power had been reduced from a high of 677,000 to 152,000 as of May 2, he said.

Outages come as a result of damaged TVA lines and also a smaller, extensive network of locally owned distributor lines.

The shutdown of Browns Ferry should not cause a financial strain for TVA and its ratepayers, Golden said. The outages resulted in less power needed.

TVA, an independent federal agency that receives no tax dollars, sells power to distributors throughout Tennessee and parts of six other states.

Ontario Provides Stable Electricity Pricing for Industrial and Commercial Companies

Ontario ICI Electricity Pricing Freeze helps Industrial Conservation Initiative (ICI) participants by stabilizing Global Adjustment charges, suspending peak hours curtailment, and reducing COVID-19-related electricity cost volatility to support large employers returning operations to full capacity.

 

Key Points

A two-year policy stabilizing GA costs and pausing peak-hour cuts to aid industrial and commercial recovery.

✅ GA cost share frozen for two years

✅ No peak-hour curtailment obligations

✅ Supports industrial and commercial restart

 

The Ontario government is helping large industrial and commercial companies return to full levels of operation without the fear of electricity costs spiking by providing more stable electricity pricing for two years. Effective immediately, companies that participate in the Industrial Conservation Initiative (ICI) will not be required to reduce their electricity usage during peak hours or shift some load to ultra-low overnight pricing where applicable, as their proportion of Global Adjustment (GA) charges for these companies will be frozen.

"Ontario's industrial and commercial electricity consumers continue to experience unprecedented economic challenges during COVID-19, with electricity relief for households and small businesses introduced to help," said Greg Rickford, Minister of Energy, Northern Development and Mines. "Today's announcement will allow large industrial employers to focus on getting their operations up and running and employees back to work, instead of adjusting operations in response to peak electricity demand hours."

Due to COVID-19, electricity consumption in Ontario has been below average as fall in demand as people stayed home across the province, and the province is forecast to have a reliable supply of electricity, supported by the system operator's staffing contingency plans during the pandemic, to accommodate increased usage. Peak hours generally occur during the summer when the weather is hot and electricity demand from cooling systems is high.

"Today's action will reduce the burden of anticipating and responding to peak hours for more than 1,300 ICI participants with 2,000 primarily industrial facilities in Ontario," said Bill Walker, Associate Minister of Energy. "Now these large employers can focus on getting their operations back up and running at full tilt and explore new energy-efficiency programs to manage costs."

The government previously announced it was providing temporary relief for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan (RPP) by deferring a portion of GA charges for April, May and June 2020 and by extending off-peak rates for many customers, as well as a disconnect moratorium extension for residential electricity users.

US Automakers Will Build 30,000 Electric Vehicle Chargers

Automaker EV Fast-Charging Network will deploy 30,000 DC fast chargers across US and Canada, supporting CCS and NACS, integrating Tesla compatibility, easing range anxiety, and expanding highway and urban charging infrastructure with amenities and uptime.

 

Key Points

A $1B joint venture by seven automakers to build 30,000 DC fast chargers with CCS and NACS across the US and Canada.

✅ 30,000 DC fast chargers by 2030 across US and Canada

✅ Supports CCS and NACS; Tesla compatibility planned

✅ Launching mid-2024; focus on highways, urban hubs, amenities

 

Seven major automakers announced a plan on Wednesday to nearly double the number of fast chargers in the United States in an effort to address one of the main reasons that people hesitate to buy electric cars, even as the age of electric cars accelerates.

The carmakers — BMW Group, General Motors, Honda, Hyundai, Kia, Mercedes-Benz Group and Stellantis — will initially invest at least $1 billion in a joint venture that will build 30,000 charging ports on major highways and other locations in the United States and Canada.

The United States and Canada have about 36,000 fast chargers — those that can replenish a drained battery in 30 minutes or less. In some sparsely populated areas, such chargers can be hundreds of miles apart. Surveys show that fear about not being able to find a charger during longer journeys is a major reason that some car buyers are reluctant to buy electric vehicles.

Sales of electric vehicles have risen quickly in the United States as the market hits an inflection point, but there are signs that demand is softening. As a result, Tesla, Ford and other carmakers have cut prices in recent months and are offering incentives. Popular models that had long waiting lists last year are now available in a few days or weeks.

Major carmakers are investing billions of dollars to manufacture electric vehicles and batteries and to establish supplier networks. Having staked their futures on the technology, they have a strong incentive to ensure that electric vehicles catch on with car buyers, even as gas-electric hybrids help bridge the transition.

The chargers installed by the joint venture will have plugs designed for the connections used by most carmakers other than Tesla, as well as the standard developed by Tesla, amid fights for control over charging, that Ford, G.M. and other companies have said they intend to switch to in 2025.

“The better experience people have, the faster E.V. adoption will grow,” Mary T. Barra, the chief executive of General Motors, said in a statement.

The seven automakers plan to formalize the joint venture and announce its name by the end of the year, Chris Martin, a Honda spokesman, said. The first chargers will begin operating around the middle of 2024, he said, with all 30,000 in place by the end of the decade.

The joint venture is open to adding other partners, he said. Among major automakers, Ford was a notable absence from the announcement on Wednesday. The company said in a statement on Wednesday that it would continue to iThe partnership also does not include Volkswagen. The company is a majority shareholder of Electrify America, one of the largest fast-charging providers.

Tesla accounts for more than half the fast chargers in the United States and has said it will open its networks to other car brands, though, so far, it has only made fewer than 100 ports available. Owners of Ford and G.M. vehicles, among others, will be able to connect to 12,000 Tesla fast chargers using an adapter beginning next year. In 2025, Ford and G.M. plan to make models designed to take the Tesla plug without an adapter.

The decision by the seven carmakers to form the joint venture is an indication that they do not intend to rely solely on Tesla, which dominates sales of electric vehicles, for charging.

The chargers being built by the joint venture will be concentrated in urban areas and along major highways, especially those used most heavily by vacationers and other travelers, the companies said in a joint statement. Charging stations will be close to restrooms, restaurants and other amenities. The partners said they would try to take advantage of federal and state funds available for charging infrastructure amid questions about whether the U.S. has the power to charge it at scale.

Most electric vehicle owners charge at home and rarely need to use public chargers. Home chargers typically replenish batteries overnight. Most public chargers, about 125,000 in the United States and Canada, also operate relatively slowly — taking four to 10 hours to do the job.nvest in its own network, which allows Ford owners to charge from a variety of providers with one mobile phone app.

Parisians vote to ban rental e-scooters from French capital by huge margin

Paris E-Scooter Ban: Voters back ending rental scooters after a public consultation, citing road safety, pedestrian clutter, and urban mobility concerns; impacts Lime, Dott, and Tier operations across the capital.

 

Key Points

A citywide prohibition on rental e-scooters, approved by voters, to improve safety, order, and walkability.

✅ Non-binding vote shows about 90% support citywide.

✅ About 15,000 rental scooters from Lime, Dott, Tier affected.

✅ Cites 2022 injuries, fatalities, and sidewalk clutter.

 

Parisians have voted to rid the streets of the French capital of rental electric scooters, with an overwhelming 90% of votes cast supporting a ban, official results show, amid a wider debate over the limits of the electric-car revolution and its real-world impact.

Paris was a pioneer when it introduced e-scooters, or trottinettes, in 2018 as the city’s authorities sought to promote non-polluting forms of urban transport, amid record EV adoption in France across the country.

But as the two-wheeled vehicles grew in popularity, especially among young people, and, with similar safety concerns prompting the TTC winter ban on lithium-ion e-bikes and scooters in Toronto, so did the number of accidents: in 2022, three people died and 459 were injured in e-scooter accidents in Paris.

In what was billed as a “public consultation” voters were asked: “For or against self-service scooters?”

Twenty-one polling stations were set up across the city and were open until 7pm local time. Although 1.6 million people are eligible to vote, turnout is expected to be low.

The ban won between 85.77% and 91.77% of the votes in the 20 Paris districts that published results, according to the City of Paris website on what was billed as a rare “public consultation” and prompted long queues at ballot boxes around the city. The vote was non-binding but city authorities have vowed to follow the result, echoing Britain's transport rethink that questions simple fixes.

Paris’s socialist mayor, Anne Hidalgo, has promoted cycling and bike-sharing but supported a ban on e-scooters, as France rolls out new EV incentive rules affecting Chinese manufacturers.

In an interview with Agence France-Presses last week, Hidalgo said “self-service scooters are the source of tension and worry” for Parisians and that a ban would “reduce nuisance” in public spaces, with broader benefits for air quality noted in EV use linked to fewer asthma ER visits in recent studies as well.

Paris has almost 15,000 e-scooters across its streets, operated by companies including Lime, Dott and Tier. Detractors argue that e-scooter users disrespect the rules of the road and regularly flout a ban on riding on pavements, even as France moves to discourage Chinese EV purchases to shape the broader mobility market. The vehicles are also often haphazardly parked or thrown into the River Seine.

In June 2021, a 31-year-old Italian woman was killed after being hit by an e-scooter with two passengers onboard while walking along the Seine.

“Scooters have become my biggest enemy. I’m scared of them,” Suzon Lambert, a 50-year-old teacher from Paris, told AFP. “Paris has become a sort of anarchy. There’s no space any more for pedestrians.”


Another Parisian told BFMTV: “It’s dangerous, and people use them badly. I’m fed up.”

Julian Sezgin, aged 15, said he often saw groups of two or three teenagers on e-scooters zooming past cars on busy roads. “I avoid going on e-scooters and prefer e-bikes as, in my opinion, they are safer and more efficient,” he told the Guardian.

Bianca Sclavi, an Italian who has lived in Paris for years, said the scooters go “too fast” and should be mechanically limited so they go slower. “They are dangerous because they zip in and out of traffic,” she said. “However, it is not as bad as when they first arrived … the most dangerous are the drunk tourists!”

Crossrail will generate electricity using the wind created by trains

Urban Piezoelectric Energy Textiles capture wind-driven motion on tunnels, bridges, and facades, enabling renewable microgeneration for smart cities with decentralized power, resilient infrastructure, and flexible lamellae sheets that harvest airflow vibrations.

 

Key Points

Flexible piezoelectric sheets that convert urban wind and vibration into electricity on tunnels, bridges, and facades.

✅ Installed on London Crossrail to test airflow energy capture

✅ Flexible lamellae panels retrofit tunnels, bridges, facades

✅ Supports decentralized, resilient urban microgrids

 

Charlotte Slingsby and her startup Moya Power are researching piezo-electric textiles that gain energy from movement, similar to advances like a carbon nanotube energy harvester being explored by materials researchers. It seems logical that Slingsby originally came from a city with a reputation for being windy: “In Cape Town, wind is an energy source that you cannot ignore,” says the 27-year-old, who now lives in London.

Thanks to her home city, she also knows about power failures. That’s why she came up with the idea of not only harnessing wind as an alternative energy source by setting up wind farms in the countryside or at sea, but also for capturing it in cities using existing infrastructure.

 

The problem

The United Nations estimates that by 2050, two thirds of the world’s population will live in cities. As a result, the demand for energy in urban areas will increase dramatically, spurring interest in nighttime renewable technology that can operate when solar and wind are variable. Can the old infrastructure grow fast enough to meet demand? How might we decentralise power generation, moving it closer to the residents who need it?

For a pilot project, she has already installed grids of lamellae-covered plastic sheets in tunnels on London Crossrail routes; the draft in the tube causes the protrusions to flutter, which then generates electricity.

“If we all live in cities that need electricity, we need to look for new, creative ways to generate it, including nighttime solar cells that harvest radiative cooling,” says Slingsby, who studied design and engineering at Imperial College and the Royal College of Art. “I wanted to create something that works in different situations and that can be flexibly adapted, whether you live in an urban hut or a high-rise.”

The yield is low compared to traditional wind power plants and is not able to power whole cities, but Slingsby sees Moya Power as just a single element in a mixture of urban energy sources, alongside approaches like gravity power that aid grid decarbonization.

In the future, Slingsby’s invention could hang on skyscrapers, in tunnels or on bridges – capturing power in the windiest parts of the city, alongside emerging air-powered generators that draw energy from humidity. The grey concrete of tunnels and urban railway cuttings could become our cities’ most visually appealing surfaces...

U.S. Launches $250 Million Program To Strengthen Energy Security For Rural Communities

DOE RMUC Cybersecurity Program supports rural, municipal, and small investor-owned utilities with grants, technical assistance, grid resilience, incident response, workforce training, and threat intelligence sharing to harden energy systems and protect critical infrastructure.

 

Key Points

A $250M DOE program providing grants to boost rural and municipal utilities' cybersecurity and incident response.

✅ Grants and technical assistance for grid security

✅ Enhances incident response and threat intel sharing

✅ Builds cybersecurity workforce in rural utilities

 

The U.S. Department of Energy (DOE) today issued a Request for Information (RFI) seeking public input on a new $250 million program to strengthen the cybersecurity posture of rural, municipal, and small investor-owned electric utilities.

Funded by President Biden’s Bipartisan Infrastructure Law and broader clean energy funding initiatives, the Rural and Municipal Utility Advanced Cybersecurity Grant and Technical Assistance (RMUC) Program will help eligible utilities harden energy systems, processes, and assets; improve incident response capabilities; and increase cybersecurity skills in the utility workforce. Providing secure, reliable power to all Americans, with a focus on equity in electricity regulation across communities, will be a key focus on the pathway to achieving President Biden’s goal of a net-zero carbon economy by 2050. 

“Rural and municipal utilities provide power for a large portion of low- and moderate-income families across the nation and play a critical role in ensuring the economic security of our nation’s energy supply,” said U.S. Secretary of Energy Jennifer M. Granholm. “This new program reflects the Biden Administration's commitment to improving energy reliability and connecting our nation’s rural communities to resilient energy infrastructure and the transformative benefits that come with it.” 

Nearly one in six Americans live in a remote or rural community. Utilities in these communities face considerable obstacles, including difficulty recruiting top cybersecurity talent, inadequate infrastructure, as the aging U.S. power grid struggles to support new technologies, and lack of financial resources needed to modernize and harden their systems. 

The RMUC Program will provide financial and technical assistance to help rural, municipal, and small investor-owned electric utilities improve operational capabilities, increase access to cybersecurity services, deploy advanced cyber security technologies, and increase participation of eligible entities in cybersecurity threat information sharing programs and coordination with federal partners initiatives. Priority will be given to eligible utilities that have limited cybersecurity resources, are critical to the reliability of the bulk power system, or those that support our national defense infrastructure. 

The Office of Cybersecurity, Energy Security, and Emergency Response (CESER), which advances U.S. energy security objectives, will manage the RMUC Program, providing $250 million dollars in BIL funding over five years. To help inform Program implementation, DOE is seeking input from the cybersecurity community, including eligible utilities and representatives of third parties and organizations that support or interact with these utilities. The RFI seeks input on ways to improve cybersecurity incident preparedness, response, and threat information sharing; cybersecurity workforce challenges; risks associated with technologies deployed on the electric grid; national-scale initiatives to accelerate cybersecurity improvements in these utilities; opportunities to strengthen partnerships and energy security support efforts; the selection criteria and application process for funding awards; and more.

Power Outage Disrupts Morning Routine for Thousands in London

London, Ontario Power Outage disrupts the electricity grid, causing a citywide blackout, stalled commuters, dark traffic signals, and closed businesses, as London Hydro crews race restoration after a transformer malfunction and infrastructure failures.

 

Key Points

A blackout caused by a transformer malfunction, disrupting commuters, businesses, and traffic across London, Ontario.

✅ Traffic signals dark; delays and congestion citywide

✅ London Hydro crews repairing malfunctioning transformer

✅ Businesses closed; transit routes delayed and rerouted

 

A widespread power outage early Monday morning left thousands of residents in London, Ontario, without electricity, causing significant disruption for commuters and businesses at the start of the workday. The outage, which affected several neighborhoods across the city, lasted for hours, creating a chaotic morning as residents scrambled to adjust to the unexpected interruption.

The Outage Strikes

The power failure was first reported at approximately 6:30 a.m., catching many off guard as they began their day. The affected areas included several busy neighborhoods, with power lines down and substations impacted, issues that windstorms often exacerbate for utilities. Early reports indicated that the outage was caused by a combination of issues, including technical failures and possible equipment malfunctions. London Hydro, the city's primary electricity provider, responded quickly to the situation, assuring residents that crews were dispatched to restore power as soon as possible.

"Crews are on site and working hard to restore power to those affected," a spokesperson for London Hydro said. "We understand the frustration this causes and are doing everything we can to get the power back on as soon as possible."

Impact on Commuters and Businesses

The power outage had an immediate impact on the morning commute. Traffic lights across the affected areas were down, leading to delays and rush-hour disruptions at major intersections. Drivers were forced to navigate through intersections without traffic control, creating an additional layer of complexity for those trying to get to work or school.

Public transit was also affected, with some bus routes delayed due to the power loss at key transit stations. The situation added further stress to commuters already dealing with the challenges of a typical Monday morning rush.

Businesses in the affected neighborhoods faced a variety of challenges. Some were forced to close early or delay their opening hours due to a lack of electricity. Many shops and offices struggled with limited access to the internet and phone lines, which hindered their ability to process orders and serve customers. Local coffee shops, often a go-to for busy workers, were also unable to operate their coffee machines or provide basic services, forcing customers to go without their usual morning caffeine fix.

"For a lot of people, it's their first stop in the morning," said one local business owner. "It’s frustrating because we rely on power to function, and with no warning, we had to turn away customers."

The Response

As the hours ticked by, residents were left wondering when the power would return. London Hydro’s social media accounts were filled with updates, keeping residents informed about the restoration efforts, a practice echoed when BC Hydro crews responded during an atypical storm. The utility company urged those who were experiencing issues to report them online to help prioritize repair efforts.

"We are aware that many people are affected, and our teams are working tirelessly to restore power," the utility posted on Twitter. "Please stay safe, and we thank you for your patience."

Throughout the morning, the power was gradually restored to different areas of the city. However, some parts remained without electricity well into the afternoon, a situation reminiscent of extended outages that test city resilience. London Hydro confirmed that the outage was caused by a malfunctioning transformer, and the necessary repairs would take time to complete.

Long-Term Effects and Community Concerns

While the immediate effects of the outage were felt most acutely during the morning hours, some residents expressed concern about the potential long-term effects. The city’s reliance on a stable electricity grid became a focal point of discussion, with many wondering if similar outages could occur in the future, as seen in the North Seattle outage earlier this year.

"I understand that things break, but it’s frustrating that it took so long for power to come back," said a London resident. "This isn’t the first time something like this has happened, and it makes me wonder about the reliability of our infrastructure."

City officials responded by reassuring residents that efforts are underway to upgrade the city's infrastructure to prevent such outages from happening in the future. A report released by London Hydro highlighted ongoing investments in upgrading transformers and other key components of the city's power grid. Province-wide, Hydro One restored power to more than 277,000 customers after damaging storms, underscoring the scale of upgrades needed. Despite these efforts, however, experts warn that older infrastructure in some areas may still be vulnerable to failure, especially during extreme weather events or other unforeseen circumstances.

The morning outage serves as a reminder of how reliant modern cities are on stable electricity networks. While the response from London Hydro was swift and effective in restoring power, it’s clear that these types of events can cause significant disruptions to daily life. As the city moves forward, many are calling for increased investment in infrastructure and proactive measures to prevent future outages, especially after Toronto outages persisted following a spring storm in the region.

In the meantime, Londoners have adapted, finding ways to go about their day as best they can. For some, it’s a reminder of the importance of preparedness in an increasingly unpredictable world. Whether it’s an extra flashlight or a backup power source, residents are learning to expect the unexpected and be ready for whatever the next workday might bring.
