"Being in-tune with our customers' needs is more important than ever. As we continue to navigate the COVID-19 pandemic, customers tell us that choice and flexibility, alongside electricity relief, will help them during this difficult time," said Jason Fitzsimmons, Chief Corporate Affairs and Customer Care Officer, Hydro One. "As a customer-driven organization, we have an important responsibility to support customers with relief, flexibility and choice."

According to recent research conducted by Angus Reid, 78 per cent of Ontario electricity customers said balanced billing would help them better manage their finances, even as peak hydro rates remained unchanged for many self-isolating customers. Balanced billing flattens out the spikes in electricity usage that commonly occurs in the summer due to air conditioning use and in the winter due to heating.

The research also found that 72 per cent of customers would like to pick their own due date to better manage their finances. This feature is now included in Hydro One's new customization bundle, which will be shared with customers through an awareness campaign. Other customization tools include alerts when electricity usage falls outside of the customer's normal pattern, the ability to report outages online and the ability to receive text messages or emails when outages occur. Customers can visit www.HydroOne.com/Choice to learn more.

"Customers can pick and choose the tools that work best for them. We are now able to offer a suite of features built for any lifestyle as our employees support Ontario's COVID-19 response across the province," said Fitzsimmons.

In addition to these customization options, Hydro One has also developed a number of customer support measures during COVID-19, including a Pandemic Relief Fund to offer payment flexibility and financial assistance to customers. The company is also extending its ban on electricity disconnections to ensure that no customer is disconnected at a time when support is needed most. More information about Hydro One's Pandemic Relief Program can be found at www.HydroOne.com/PandemicRelief. Customers can continue to contact Hydro One to determine individual payment plans and determine financial assistance programs available to meet their needs, especially as disconnection pressures can arise for some households.

Hydro-Quebec hydropower exports deliver low-carbon electricity to New England, sparking debate on greenhouse gas accounting, grid attributes, and REC-style certificates as Quebec modernizes monitoring to verify emissions, integrate renewables, and meet ambitious climate targets.

Key Points

Low-carbon electricity to New England, with improved emissions tracking and verifiable grid attributes.

✅ Deep, narrow reservoirs cut lifecycle GHGs in cold boreal waters

✅ Attribute certificates trace source, type, and carbon intensity

✅ Contracts require facility-level tagging for compliance

For 40 years, through the most vicious interprovincial battles, even as proposals for bridging the Alberta-B.C. gap aimed to improve grid resilience, Canadians could agree on one way Quebec is undeniably superior to the rest of the country.

It’s hydropower, and specifically the mammoth dam system in Northern Quebec that has been paying dividends since it was first built in the 70s. “Quebec continues to boast North America’s lowest electricity prices,” was last year’s business-as-usual update in one trade publication, even as Newfoundland's rate strategy seeks relief for consumers.

With climate crisis looming, that long-ago decision earns even more envy and reflects Canada's electricity progress across the grid today. Not only do they pay less, but Quebeckers also emit the least carbon per capita of any province.

It may surprise most Canadians, then, to hear how most of New England has reacted to the idea of being able to buy permanently into Quebec’s power grid.

​​​​​​Hydro-Québec’s efforts to strike major export deals have been rebuffed in the U.S., by environmentalists more than anyone. They question everything about Quebec hydropower, including asking “is it really low-carbon?”

These doubts may sound nonsensical to regular Quebeckers. But airing them has, in fact, pushed Hydro-Québec to learn more about itself and adopt new technology.

We know far more about hydropower than we knew 40 years ago, including whether it’s really zero-emission (it’s not), how to make it as close to zero-emission as possible, and how to account for it as precisely as new clean energies like solar and wind, underscoring how cleaning up Canada's electricity is vital to meeting climate pledges.

The export deals haven’t gone through yet, but they’ve already helped drag Hydro-Québec—roughly the fourth-biggest hydropower system on the planet—into the climate era.

Fighting to export
One of the first signs of trouble for Quebec hydro was in New Hampshire, almost 10 years ago. People there began pasting protest signs on their barns and buildings. One citizens’ group accused Hydro of planning a “monstrous extension cord” across the state.

Similar accusations have since come from Maine, Massachusetts and New York.

The criticism isn’t coming from state governments, which mostly want a more permanent relationship with Hydro-Québec. They already rely on Quebec power, but in a piecemeal way, topping up their own power grid when needed (with the exception of Vermont, which has a small permanent contract for Quebec hydropower).

Last year, Quebec provided about 15 percent of New England’s total power, plus another substantial amount to New York, which is officially not considered to be part of New England, and has its own energy market separate from the New England grid.

Now, northeastern states need an energy lynch pin, rather than a top-up, with existing power plants nearing the end of their lifespans. In Massachusetts, for example, one major nuclear plant shut down this year and another will be retired in 2021. State authorities want a hydro-based energy plan that would send $10 billion to Hydro-Québec over 20 years.

New England has some of North America’s most ambitious climate goals, with every state in the region pledging to cut emissions by at least 80 percent over the next 30 years.

What’s the downside? Ask the citizens’ groups and nonprofits that have written countless op-eds, organized petitions and staged protests. They argue that hydropower isn’t as clean as cutting-edge clean energy such as solar and wind power, and that Hydro-Québec isn’t trying hard enough to integrate itself into the most innovative carbon-counting energy system. Right as these other energy sources finally become viable, they say, it’s a step backwards to commit to hydro.

As Hydro-Québec will point out, many of these critics are legitimate nonprofits, but others may have questionable connections. The Portland Press Herald in Maine reported in September 2018 that a supposedly grassroot citizens’ group called “Stand Up For Maine” was actually funded by the New England Power Generators Association, which is based in Boston and represents such power plant owners as Calpine Corp., Vistra Energy and NextEra Energy.

But in the end, that may not matter. Arguably the biggest motivator to strike these deals comes not from New England’s needs, but from within Quebec. The province has spent more than $10 billion in the last 15 years to expand its dam and reservoir system, and in order to stay financially healthy, it needs to double its revenue in the next 10 years—a plan that relies largely on exports.

With so much at stake, it has spent the last decade trying to prove it can be an energy of the future.

“Learning as you go”
American critics, justified or not, have been forcing advances at Hydro for a long time.

When the famously huge northern Quebec hydro dams were built at James Bay—construction began in the early 1970s—the logic was purely economic. The term “climate change” didn’t exist. The province didn’t even have an environment department.

The only reason Quebec scientists started trying to measure carbon emissions from hydro reservoirs was “basically because of the U.S.,” said Alain Tremblay, a senior environmental advisor at Hydro Quebec.

In the early 1990s, Hydro began to export power to the U.S., and “because we were a good company in terms of cost and efficiency, some Americans didn't like that,” he said—mainly competitors, though he couldn’t say specifically who. “They said our reservoirs were emitting a lot of greenhouse gases.”

The detractors had no research to back up that claim, but Hydro-Québec had none to refute it, either, said Tremblay. “At that time we didn’t have any information, but from back-of-the envelope calculations, it was impossible to have the emissions the Americans were expecting we have.”

So research began, first to design methods to take the measurements, and then to carry them out. Hydro began a five-year project with a Quebec university.

It took about 10 years to develop a solid methodology, Tremblay said, with “a lot of error and learning-as-you-go.” There have been major strides since then.

“Twenty years ago we were taking a sample of water, bringing it back to the lab and analyzing that with what we call a gas chromatograph,” said Tremblay. “Now, we have an automated system that can measure directly in the water,” reading concentrations of CO2 and methane every three hours and sending its data to a processing centre.

The tools Hydro-Québec uses are built in California. Researchers around the world now follow the same standard methods.

At this point, it’s common knowledge that hydropower does emit greenhouse gases. Experts know these emissions are much higher than previously thought.

​But Hydro-Québec now has the evidence, also, to rebut the original accusations from the early 1990s and many similar ones today.

“All our research from Université Laval [found] that it’s about a thousand years before trees decompose in cold Canadian waters,” said Tremblay.

Hydro reservoirs emit greenhouse gases because vegetation and sometimes other biological materials, like soil runoff, decay under the surface.

But that decay depends partly on the warmth of the water. In tropical regions, including the southern U.S., hydro dams can have very high emissions. But in boreal zones like northern Quebec (or Manitoba, Labrador and most other Canadian locations with massive hydro dams), the cold, well-oxygenated water vastly slows the process.

Hydro emissions have “a huge range,” said Laura Scherer, an industrial ecology professor at Leiden University in the Netherlands who led a study of almost 1,500 hydro dams around the world.

“It can be as low as other renewable energy sources, but it can also be as high as fossil fuel energy,” in rare cases, she said.

While her study found that climate was important, the single biggest factor was “sizing and design” of each dam, and specifically its shape, she said. Ideally, hydro dams should be deep and narrow to minimize surface area, perhaps using a natural valley.

Hydro-Québec’s first generation of dams, the ones around James Bay, were built the opposite way—they’re wide and shallow, infamously flooding giant tracts of land.

Newly built ones take that new information into account, said Tremblay. Its most recent project is the Romaine River complex, which will eventually include four reservoirs near Quebec’s northeastern border with Labrador. Construction began in 2016.

The site was picked partly for its topography, said Tremblay.

“It’s a valley-type reservoir, so large volume, small surface area, and because of that there’s a pretty limited amount of vegetation that’s going to be flooded,” he said.

There’s a dramatic emissions difference with the project built just before that, commissioned in 2006. Called Eastmain, it’s built near James Bay.

“The preliminary results indicate with the same amount of energy generated [by Romaine] as with Eastmain, you’re going to have about 10 times less emissions,” said Tremblay.

Tracing energy to its source
These signs of progress likely won’t satisfy the critics, who have publicly argued back and forth with Hydro about exactly how emissions should be tallied up.

But Hydro-Québec also faces a different kind of growing gap when it comes to accounting publicly for its product. In the New England energy market, a sophisticated system “tags” all the energy in order to delineate exactly how much comes from which source—nuclear, wind, solar, and others—and allows buyers to single out clean power, or at least the bragging rights to say they bought only clean power.

Really, of course, it’s all the same mix of energy—you can’t pick what you consume. But creating certificates prevents energy producers from, in worst-case scenarios, being able to launder regular power through their clean-power facilities. Wind farms, for example, can’t oversell what their own turbines have produced.

What started out as a fraud prevention tool has “evolved to make it possible to also track carbon emissions,” said Deborah Donovan, Massachusetts director at the Acadia Center, a climate-focused nonprofit.

But Hydro-Québec isn’t doing enough to integrate itself into this system, she says.

It’s “the tool that all of our regulators in New England rely on when we are confirming to ourselves that we’ve met our clean energy and our carbon goals. And…New York has a tool just like that,” said Donovan. “There isn’t a tracking system in Canada that’s comparable, though provinces like Nova Scotia are tapping the Western Climate Initiative for technical support.”

Developing this system is more a question of Canadian climate policy than technology.

Energy companies have long had the same basic tracking device—a meter, said Tanya Bodell, a consultant and expert in New England’s energy market. But in New England, on top of measuring “every time there’s a physical flow of electricity” from a given source, said Bodell, a meter “generates an attribute or a GIS certificate,” which certifies exactly where it’s from. The certificate can show the owner, the location, type of power and its average emissions.

Since 2006, Hydro-Québec has had the ability to attach the same certificates to its exports, and it sometimes does.

“It could be wind farm generation, even large hydro these days—we can do it,” said Louis Guilbault, who works in regulatory affairs at Hydro-Québec. For Quebec-produced wind energy, for example, “I can trade those to whoever’s willing to buy it,” he said.

But, despite having the ability, he also has the choice not to attach a detailed code—which Hydro doesn’t do for most of its hydropower—and to have it counted instead under the generic term of “system mix.”

Once that hydropower hits the New England market, the administrators there have their own way of packaging it. The market perhaps “tries to determine emissions, GHG content,” Guilbault said. “They have their own rules; they do their own calculations.”

This is the crux of what bothers people like Donovan and Bodell. Hydro-Québec is fully meeting its contractual obligations, since it’s not required to attach a code to every export. But the critics wish it would, whether by future obligation or on its own volition.

Quebec wants it both ways, Donovan argued; it wants the benefits of selling low-emission energy without joining the New England system of checks and balances.

“We could just buy undifferentiated power and be done with it, but we want carbon-free power,” Donovan said. “We’re buying it because of its carbon content—that’s the reason.”

Still, the requirements are slowly increasing. Under Hydro-Québec’s future contract with Massachusetts (which still has several regulatory steps to go through before it’s approved) it’s asked to sell the power’s attributes, not just the power itself. That means that, at least on paper, Massachusetts wants to be able to trace the energy back to a single location in Quebec.

“It’s part of the contract we just signed with them,” said Guilbault. “We’re going to deliver those attributes. I’m going to select a specific hydro facility, put the number in...and transfer that to the buyers.”

Hydro-Québec says it’s voluntarily increasing its accounting in other ways. “Even though this is not strictly required,” said spokeswoman Lynn St. Laurent, Hydro is tracking its entire output with a continent-wide registry, the North American Renewables Registry.

That registry is separate from New England’s, so as far as Bodell is concerned, the measure doesn’t really help. But she and others also expect the entire tracking system to grow and mature, perhaps integrating into one. If it had been created today, in fact, rather than in the 1990s, maybe it would use blockchain technology rather than a varied set of administrators, she said.

Counting emissions through tracking still has a long way to go, as well, said Donovan, and it will increasingly matter in Canada's race to net-zero as standards tighten. For example, natural gas is assigned an emissions number that’s meant to reflect the emissions when it’s consumed. But “we do not take into account what the upstream carbon emissions are through the pipeline leakage, methane releases during fracking, any of that,” she said.

Now that the search for exactitude has begun, Hydro-Québec won’t be exempt, whether or not Quebeckers share that curiosity. “We don’t know what Hydro-Québec is doing on the other side of the border,” said Donovan.

Europe's Nuclear Energy Policy shapes responses to the energy crisis, soaring gas prices, EU taxonomy rules, net-zero goals, renewables integration, baseload security, SMRs, and Russia-Ukraine geopolitics, exposing cultural, financial, and environmental divides.

Key Points

A policy guiding nuclear exits or expansion to balance energy security, net-zero goals, costs, and EU taxonomy.

✅ Divergent national stances: phase-outs vs. new builds

✅ Costs, delays, and waste challenge large reactors

✅ SMRs, renewables, and gas shape net-zero pathways

As the Fukushima disaster unfolded in Japan in 2011, then-German Chancellor Angela Merkel made a dramatic decision that delighted her country’s anti-nuclear movement: all reactors would be ditched.

What couldn’t have been predicted was that Europe would find itself mired in one of the worst energy crises in its history. A decade later, the continent’s biggest economy has shut down almost all its capacity already. The rest will be switched off at the end of 2022 — at the worst possible time.

Wholesale power prices are more than four times what they were at the start of the coronavirus pandemic. Governments are having to take emergency action to support domestic and industrial consumers faced with crippling bills, which could rise higher if the tension over Ukraine escalates. The crunch has not only exposed Europe’s supply vulnerabilities, but also the entrenched cultural and political divisions over the nuclear industry and a failure to forge a collective vision. 

Other regions meanwhile are cracking on, challenging the idea that nuclear power is in decline worldwide. China is moving fast on nuclear to try to clean up its air quality. Its suite of reactors is on track to surpass that of the U.S., the world’s largest, by as soon as the middle of this decade. Russia is moving forward with new stations at home and has more than 20 reactors confirmed or planned for export construction, according to the World Nuclear Association.

“I don’t think we’re ever going to see consensus across Europe with regards to the continued running of existing assets, let alone the construction of new ones,” said Peter Osbaldstone, research director for power and renewables at Wood Mackenzie Group Ltd. in the U.K. “It’s such a massive polarizer of opinions that national energy policy is required in strength over a sustained period to support new nuclear investment.” 

France, Europe’s most prolific nuclear energy producer, is promising an atomic renaissance as its output becomes less reliable. Britain plans to replace aging plants in the quest for cleaner, more reliable energy sources. The Netherlands wants to add more capacity, Poland also is seeking to join the nuclear club, and Finland is starting to produce electricity later this month from its first new plant in four decades. 

Belgium and Spain, meanwhile, are following Germany’s lead in abandoning nuclear, albeit on different timeframes. Austria rejected it in a referendum in 1978.

Nuclear power is seen by its proponents as vital to reaching net-zero targets worldwide. Once built, reactors supply low-carbon electricity all the time, unlike intermittent wind or solar.

Plants, though, take a decade or more to construct at best and the risk is high of running over time and over budget. Finland’s new Olkiluoto-3 unit is coming on line after a 12-year delay and billions of euros in financial overruns. 

Then there’s the waste, which stays hazardous for 100,000 years. For those reasons European Union members are still quarreling over whether nuclear even counts as sustainable.

Electorates are also split. Polling by YouGov Plc published in December found that Danes, Germans and Italians were far more nuclear-skeptic than the French, British or Spanish. 

“It comes down to politics,” said Vince Zabielski, partner at New York-based law firm Pillsbury Winthrop Shaw Pittman LLP, who was a nuclear engineer for 15 years. “Everything political ebbs and flows, but when the lights start going off people have a completely different perspective.”

What’s Behind Europe’s Skyrocketing Energy Prices

Indeed, there’s a risk of rolling blackouts this winter. Supply concerns plaguing Europe have sent gas and electricity prices to record levels and inflation has ballooned. There’s also mounting tension with Russia over a possible invasion of Ukraine, which could lead to disrupted supplies of gas. All this is strengthening the argument that Europe needs to reduce its dependence on international sources of gas.

Europe will need to invest 500 billion euros ($568 billion) in nuclear over the next 30 years to meet growing demand for electricity and achieve its carbon reduction targets, according to Thierry Breton, the EU’s internal market commissioner. His comments come after the bloc unveiled plans last month to allow certain natural gas and nuclear energy projects to be classified as sustainable investments. 

“Nuclear power is a very long-term investment and investors need some kind of guarantee that it will generate a payoff,” said Elina Brutschin at the International Institute for Applied Systems Analysis. In order to survive in liberalized economies like the EU, the technology needs policy support to help protect investors, she said.

That already looks like a tall order. The European Commission has been told by a key expert group that the labeling risks raising greenhouse gas emissions and undermining the bloc’s reputation as a bastion for environmentally friendly finance.

Austria has threatened to sue the European Commission over attempts to label atomic energy as green. The nation previously attempted a legal challenge, when the U.K. was still an EU member, to stop the construction of Electricite de France SA’s Hinkley Point C plant, in the west of England. It has also commenced litigation against new Russia-backed projects in neighboring Hungary.

Germany, which has missed its carbon emissions targets for the past two years, has been criticized by some environmentalists and climate scientists for shutting down a supply of clean power at the worst time, despite arguments for a nuclear option for climate policy. Its final three reactors will be halted this year. Yet that was never going to be reversed with the Greens part of the new coalition government. 

The contribution of renewables in Germany has almost tripled since the year before Fukushima, and was 42% of supply last year. That’s a drop from 46% from the year before and means the country’s new government will have to install some 3 gigawatts of renewables — equivalent to the generating capacity of three nuclear reactors — every year this decade to hit the country's 80% goal.

“Other countries don’t have this strong political background that goes back to three decades of anti-nuclear protests,” said Manuel Koehler, managing director of Aurora Energy Research Ltd., a company analyzing power markets and founded by Oxford University academics. 

At the heart of the issue is that countries with a history of nuclear weapons will be more likely to use the fuel for power generation. They will also have built an industry and jobs in civil engineering around that.

Germany’s Greens grew out of anti-nuclear protest movements against the stationing of U.S. nuclear missiles in West Germany. The 1986 Chernobyl meltdown, which sent plumes of radioactive fallout wafting over parts of western Europe, helped galvanize the broader population. Nuclear phase-out plans were originally laid out in 2002, but were put on hold by the country's conservative governments. The 2011 Fukushima meltdowns reinvigorated public debate, ultimately prompting Merkel to implement them.

It’s not easy to undo that commitment, said Mark Hibbs, a Bonn, Germany-based nuclear analyst at Carnegie Endowment for International Peace, or to envision any resurgence of nuclear in Germany soon: “These are strategic decisions, that have been taken long in advance.”

In France, President Emmanuel Macron is about to embark on a renewed embrace of nuclear power, even as a Franco-German nuclear dispute complicates the debate. The nation produces about two-thirds of its power from reactors and is the biggest exporter of electricity in Europe. Notably, that includes anti-nuclear Germany and Austria.

EDF, the world’s biggest nuclear plant operator, is urging the French government to support construction of six new large-scale reactors at an estimated cost of about 50 billion euros. The first of them would start generating in 2035.

But even France has faced setbacks. Development of new projects has been put on hold after years of technical issues at the Flamanville-3 project in Normandy. The plant is now scheduled to be completed next year. 

In the U.K., Business Secretary Kwasi Kwarteng said that the global gas price crisis underscores the need for more home-generated clean power. By 2024, five of Britain’s eight plants will be shuttered because they are too old. Hinkley Point C is due to be finished in 2026 and the government will make a final decision on another station before an election due in 2024. 

One solution is to build small modular reactors, or SMRs, which are quicker to construct and cheaper. The U.S. is at the forefront of efforts to design smaller nuclear systems with plans also underway in the U.K. and France. Yet they too have faced delays. SMR designs have existed for decades though face the same challenging economic metrics and safety and security regulations of big plants.

The trouble, as ever, is time. “Any investment decisions you make now aren’t going to come to fruition until the 2030s,” said Osbaldstone, the research director at Wood Mackenzie. “Nuclear isn’t an answer to the current energy crisis.”

Near-Field Thermophotovoltaics captures radiated energy across a nanoscale gap, using thin-film photovoltaic cells and indium gallium arsenide to boost power density and efficiency, enabling compact Army portable power from emitters via radiative heat transfer.

Key Points

A nanoscale TPV method capturing near-field photons for higher power density at lower emitter temperatures.

✅ Nanoscale gap boosts radiative transfer and usable photon flux

✅ Thin-film InGaAs cells recycle sub-band-gap photons via reflector

✅ Achieved ~5 kW/m2 power density with higher efficiency

With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging, with concepts such as power from falling snow illustrating how diverse new energy-harvesting approaches are. Army-funded research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power for Soldiers on future battlefields.

Hot objects radiate light in the form of photons into their surroundings. The emitted photons can be captured by a photovoltaic cell and converted to useful electric energy. This approach to energy conversion is called far-field thermophotovoltaics, or FF-TPVs, and has been under development for many years; however, it suffers from low power density and therefore requires high operating temperatures of the emitter.

The research, conducted at the University of Michigan and published in Nature Communications, demonstrates a new approach, where the separation between the emitter and the photovoltaic cell is reduced to the nanoscale, enabling much greater power output than what is possible with FF-TPVs for the same emitter temperature.

This approach, which enables capture of energy that is otherwise trapped in the near-field of the emitter is called near-field thermophotovoltaics or NF-TPV and uses custom-built photovoltaic cells and emitter designs ideal for near-field operating conditions, alongside emerging smart solar inverters that help manage conversion and delivery.

This technique exhibited a power density almost an order of magnitude higher than that for the best-reported near-field-TPV systems, while also operating at six-times higher efficiency, paving the way for future near-field-TPV applications, including remote microgrid deployments in extreme environments, according to Dr. Edgar Meyhofer, professor of mechanical engineering, University of Michigan.

"The Army uses large amounts of power during deployments and battlefield operations and must be carried by the Soldier or a weight constrained system," said Dr. Mike Waits, U.S. Army Combat Capabilities Development Command's Army Research Laboratory. "If successful, in the future near-field-TPVs could serve as more compact and higher efficiency power sources for Soldiers as these devices can function at lower operating temperatures than conventional TPVs."

The efficiency of a TPV device is characterized by how much of the total energy transfer between the emitter and the photovoltaic cell is used to excite the electron-hole pairs in the photovoltaic cell, where insights from near-light-speed conduction research help contextualize performance limits in semiconductors. While increasing the temperature of the emitter increases the number of photons above the band-gap of the cell, the number of sub band-gap photons that can heat up the photovoltaic cell need to be minimized.

"This was achieved by fabricating thin-film TPV cells with ultra-flat surfaces, and with a metal back reflector," said Dr. Stephen Forrest, professor of electrical and computer engineering, University of Michigan. "The photons above the band-gap of the cell are efficiently absorbed in the micron-thick semiconductor, while those below the band-gap are reflected back to the silicon emitter and recycled."

The team grew thin-film indium gallium arsenide photovoltaic cells on thick semiconductor substrates, and then peeled off the very thin semiconductor active region of the cell and transferred it to a silicon substrate, informing potential interfaces with home battery systems for distributed use.

All these innovations in device design and experimental approach resulted in a novel near-field TPV system that could complement distributed resources in virtual power plants for resilient operations.

"The team has achieved a record ~5 kW/m2 power output, which is an order of magnitude larger than systems previously reported in the literature," said Dr. Pramod Reddy, professor of mechanical engineering, University of Michigan.

Researchers also performed state-of-the-art theoretical calculations to estimate the performance of the photovoltaic cell at each temperature and gap size, informing hybrid designs with backup fuel cell solutions that extend battery life, and showed good agreement between the experiments and computational predictions.

"This current demonstration meets theoretical predictions of radiative heat transfer at the nanoscale, and directly shows the potential for developing future near-field TPV devices for Army applications in power and energy, communication and sensors," said Dr. Pani Varanasi, program manager, DEVCOM ARL that funded this work.

Advanced Nuclear Reactors redefine nuclear energy with SMRs, diverse fuels, passive safety, digital control rooms, and flexible heat and power, pairing veteran operator expertise with cost-efficient, carbon-free electricity for a resilient grid.

Key Points

SMR-based advanced reactors with passive cooling and digital controls deliver flexible power and process heat.

✅ Veteran operators transfer proven safety culture and risk management.

✅ SMRs, passive safety, and digital controls simplify operations.

✅ Flexible output: electricity, process heat, and grid support.

Advanced reactors will break the mold of what we think next-gen nuclear power can accomplish: some will be smaller, some will use different kinds of fuel and others will do more than just make electricity. This new technology may seem like uncharted waters, but when operators, technicians and other workers start up the first reactors of the new generation, they will bring with them years of nuclear experience to run machines that have been optimized with lessons from the current fleet.

While advanced reactors are often portrayed as the future of nuclear energy, and atomic energy is heating up across markets, its our current plants that have paved the way for these exciting innovations and which will be workhorses for years to come.

Reactor Veterans Bring Their Expertise to New Designs

Many of the workers who will operate the next generation of reactors come from a nuclear background. Even though the design of an advanced reactor may be different, the experience and instincts these operators have gained from working at the current fleet will help new plants get off to a more productive start.

They have a questioning attitude; they are always exploring what could go wrong and always understanding the notion of risk management in nuclear operations, whether its the oldest design or the newest design, said Chip Pardee, the president of Terrestrial Energy USA, who is the former chief operating officer at two nuclear utilities, Exelon Corp. and the Tennessee Valley Authority.

They have respect for the technology and a bias towards conservative decision-making.

Jhansi Kandasamy, vice president of engineering at GE Hitachi Nuclear Energy, agrees. She said that the presence of industry veterans will benefit the new modelslike the 300 megawatt boiling water reactor her company is developing.

From the beginning, a new reactor will have people who have touched it, worked on it, and experienced it, she said.

Theyre going to be able to tell you if something doesnt look right, because theyve lived through it.

Experience Informs New Reactor Design

Advanced reactors are designed by engineers who are fully familiar with existing plants and can use that experience to optimize the new ones, like a family building a house and wanting the kitchen just so. New reactors will be simpler to operate because of insights gained from years of operations of the current fleet, and some designs even integrate molten salt energy storage to enhance flexibility.

NuScale Power LLC, for example, has a very different design from the current fleet amid an advanced nuclear push that is reshaping development: up to 12 small reactorsinstead of one or two large reactorsmanaged from a single digital control roominstead of one full of analog switches and dials. When the company designed its control room, it brought in industry veterans who had collectively worked at more than two dozen nuclear plants.

The experts that NuScale brought in critiqued everything, even down to the shape of the symbols on the computer screens to make them easier to read for operators who sometimes need to quickly interpret lots of incoming data. The control panels for NuScales small modular reactor (SMR) present information according to its importance and automatically call up appropriate procedures for operators.

Many advanced reactors are also smaller than those currently operating, which makes their components simpler and less expensive. Kandasamy pointed out that the giant mechanical pumps in todays reactors generate a lot of heat and require a lot of supporting systems, including air conditioning in the rooms that house them.

GE Hitachis SMR design relies more on passive cooling so it needs fewer pumps, and those that remain use magnets, so they generate less heat. Fewer, smaller pumps means a smaller building and less cost.

Advanced Nuclear Will Further the Work of Current Reactors

Advanced reactors promise improved flexibility and the ability to do more kinds of work, including nuclear beyond electricity applications, to displace carbon and stabilize the climate. And they will continue nuclear energys legacy of providing reliable, carbon-free electricity, as a recent new U.S. reactor startup illustrates in practice. As new designs come on line over the next decade, we will continue to rely on operating plants which provide nearly 55 percent of the countrys carbon-free electricity.

The world will need all the carbon-free generation it can get for many years to come, as companies, states and countries aim for zero emissions by mid-century and pursue strategies like the green industrial revolution to accelerate deployment. That means it will need wind, solar, advanced reactors and current plants.

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

Key Points

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

✅ Power restored partially after 96 hours across all states

✅ Alleged cyber attacks at Guri Dam and Caracas systems

✅ CORPOELEC urges reduced load during grid stabilization

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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