Canada puts its nuclear pride on the block

Bruce Power Capacity Uprate boosts nuclear output through generator stator upgrades, turbine and transformer enhancements, and cooling pump improvements at Bruce A and B, unlocking megawatts and efficiency gains from legacy heavy water design capacity.

Key Points

Upgrades that raise Bruce Power capacity via stator, turbine, transformer, and cooling enhancements.

✅ Generator stator replacement increases electrical conversion efficiency

✅ Turbine and transformer upgrades enable higher MW output

✅ Cooling pump enhancements optimize plant thermal performance

Bruce Power’s Unit 3 nuclear reactor will squeeze out an extra 22 megawatts of electricity, thanks to upgrades during its recent planned outage for refurbishment.

Similar gains are anticipated at its three sister reactors at Bruce A generating station, which presents the opportunity for the biggest efficiency gains and broader economic benefits for Ontario, due to a design difference over Bruce B’s four reactors, Bruce Power spokesman John Peevers said.

Bruce A reactor efficiency gains stem mainly from the fact Bruce A’s non-nuclear side, including turbines and the generator, was sized at 88 per cent of the nuclear capacity, Peevers said, while early Bruce C exploration work advances.

This allowed 12 per cent of the energy, in the form of steam, to be used for heavy water production, which was discontinued at the plant years ago. Heavy water, or deuterium, is used to moderate the reactors.

That design difference left a potential excess capacity that Bruce Power is making use of through various non-nuclear enhancements. But the nuclear operator, which also made major PPE donations during the pandemic, will be looking at enhancements at Bruce B as well, Peevers said.

Bruce Power’s efficiency gain came from “technology advancements,” including a “generator-stator improvement project that was integral to the uprate,” and contributed to an operating record at the site, a Bruce Power news release said July 11.

Peevers said the stationary coils and the associated iron cores inside the generator are referred to as the stator. The stator acts as a conductor for the main generator current, while the turbine provides the mechanical torque on the shaft of the generator.

“Some of the other things we’re working on are transformer replacement and cooling pump enhancements, backed by recent manufacturing contracts, which also help efficiency and contribute to greater megawatt output,” Peevers said.

The added efficiency improvements raised the nuclear operator’s peak generating capacity to 6,430 MW, as projects like Pickering life extensions continue across Ontario.

Electric weed-zapping farm robots enable precision agriculture, using autonomous mapping, per-plant targeting, and robotics to reduce pesticides, improve soil health, boost biodiversity, and lower costs with data-driven, selective weeding and seed-planting workflows.

Key Points

Autonomous machines that map fields, electrocute weeds per plant, and plant seeds, cutting pesticides, inputs, and costs.

✅ Precision agriculture: per-plant targeting reduces pesticide use up to 95%.

✅ Autonomous mapping robot surveys 20 hectares per day for weed data.

✅ Electric weeding and seeding improve soil health, biodiversity, and ROI.

On a field in England, three robots have been given a mission: to find and zap weeds with electricity, as advances in digitizing the electrical system continue to modernize power infrastructure, before planting seeds in the cleared soil.

The robots — named Tom, Dick and Harry — were developed by Small Robot Company to rid land of unwanted weeds with minimal use of chemicals and heavy machinery, complementing emerging options like electric tractors that aim to cut on-farm emissions.
The startup has been working on its autonomous weed killers since 2017, and this April launched Tom, its first commercial robot which is now operational on three UK farms. The other robots are still in the prototype stage, undergoing testing.

Small Robot says robot Tom can scan 20 hectares (49 acres) a day, collecting data, with AI-driven analysis guiding Dick, a "crop-care" robot, to zap weeds. Then it's robot Harry's turn to plant seeds in the weed-free soil.

Using the full system, once it is up and running, farmers could reduce costs by 40% and chemical usage by up to 95%, the company says, and integration with virtual power plants could further optimize energy use on electrified farms.

According to the UN Food and Agriculture Organization six million metric tons of pesticides were traded globally in 2018, valued at $38 billion.

"Our system allows farmers to wean their depleted, damaged soils off a diet of chemicals," says Ben Scott-Robinson, Small Robot's co-founder and CEO.

Zapping weeds
Small Robot says it has raised over £7 million ($9.9 million). Scott-Robinson says the company hopes to launch its full system of robots by 2023, which will be offered as a service at a rate of around £400 ($568) per hectare. The monitoring robot is placed at a farm first and the weeding and planting robots delivered only when the data shows they're needed — a setup that ultimately relies on a resilient grid, where research into preventing ransomware attacks is increasingly relevant.

To develop the zapping technology, Small Robot partnered with another UK-based startup, RootWave, while innovations like electricity from snow highlight the breadth of emerging energy tech.

"It creates a current that goes through the roots of the plant through the soil and then back up, which completely destroys the weed," says Scott-Robinson. "We can go to each individual plant that is threatening the crop plants and take it out."

"It's not as fast as it would be if you went out to spray the entire field," he says. "But you have to bear in mind we only have to go into the parts of the field where the weeds are." Plants that are neutral or beneficial to the crops are left untouched.

Small Robot calls this "per plant farming" — a type of precise agriculture where every plant is accounted for and monitored.

A business case
For Kit Franklin, an agricultural engineering lecturer from Harper Adams University, efficiency remains a hurdle, even as utilities use AI to adapt to electricity demands that could support wider on-farm electrification.

"There is no doubt in my mind that the electrical system works," he tells CNN Business. "But you can cover hundreds of hectares a day with a large-scale sprayer ... If we want to go into this really precise weed killing system, we have to realize that there is an output reduction that is very hard to overcome."

But Franklin believes farmers will adopt the technology if they can see a business case.

"There's a realization that farming in an environmentally friendly way is also a way of farming in an efficient way," he says. "Using less inputs, where and when we need them, is going to save us money and it's going to be good for the environment and the perception of farmers."

As well as reducing the use of chemicals, Small Robot wants to improve soil quality and biodiversity.

"If you treat a living environment like an industrial process, then you are ignoring the complexity of it," Scott-Robinson says. "We have to change farming now, otherwise there won't be anything to farm."

MARVEL microreactor debuts at Idaho National Laboratory as a 100 kW, liquid-metal-cooled, zero-emissions generator powering a nuclear microgrid, integrating wind and solar for firm, clean energy in advanced nuclear applications research.

Key Points

A 100 kW, liquid-metal-cooled INL reactor powering a nuclear microgrid and showcasing zero-emissions clean energy.

✅ 100 kW liquid-metal-cooled microreactor at INL

✅ Powers first nuclear microgrid for applications testing

✅ Integrates with wind and solar for firm clean power

Inside the Transient Reactor Test Facility, a towering, windowless gray block surrounded by barbed wire, researchers are about to embark on a mission to solve one of humanity’s greatest problems with a tiny device.

Next year, they will begin construction on the MARVEL reactor. MARVEL stands for Microreactor Applications Research Validation and EvaLuation. It’s a first-of-a-kind nuclear power generator with a mini-reactor design that is cooled with liquid metal and produces 100 kilowatts of energy. By 2024, researchers expect MARVEL to be the zero-emissions engine of the world’s first nuclear microgrid at Idaho National Laboratory (INL).

“Micro” and “tiny,” of course, are relative. MARVEL stands 15 feet tall, weighs 2,000 pounds, and can fit in a semi-truck trailer. But it's minuscule compared to conventional nuclear power plants, which span acres, produces gigawatts of electricity to power whole states, and can take more than a decade to build.

For INL, where scientists have tested dozens of reactors over the decades across an area three-quarters the size of Rhode Island, it’s a radical reimagining of the technology. This advanced reactor design could help overcome the biggest obstacles to nuclear energy: safety, efficiency, scale, cost, and competition. MARVEL is an experiment to see how all these pieces could fit together in the real world.

“It’s an applications test reactor where we’re going to try to figure out how we extract heat and energy from a nuclear reactor and apply it — and combine it with wind, solar, and other energy sources,” said Yasir Arafat, head of the MARVEL program.

The project, however, comes at a time when nuclear power is getting pulled in wildly different directions, from phase-outs to new strategies like the UK’s green industrial revolution that shapes upcoming reactors.

Germany just shut down its last nuclear reactors. The U.S. just started up its first new reactor in 30 years, underscoring a shift. France, the country with the largest share of nuclear energy on its grid, saw its atomic power output decline to its lowest since 1988 last year. Around the world, there are currently 60 nuclear reactors under construction, with 22 in China alone.

But the world is hungrier than ever for energy. Overall electricity demand is growing: Global electricity needs will increase nearly 70 percent by 2050 compared to today’s consumption, according to the Energy Information Administration. At the same time, the constraints are getting tighter. Most countries worldwide, including the U.S., have committed to net-zero goals by the middle of the century, even as demand rises.

To meet this energy demand without worsening climate change, the U.S. Energy Department’s report on advanced nuclear energy released in March said, “the U.S. will need ~550–770 [gigawatts] of additional clean, firm capacity to reach net-zero; nuclear power is one of the few proven options that could deliver this at scale.”

The U.S. government is now renewing its bets on nuclear power to produce steady electricity without emitting greenhouse gases. The Bipartisan Infrastructure Law included $6 billion to keep existing nuclear power plants running. In addition, the Inflation Reduction Act, the U.S. government’s largest investment in countering climate change, includes several provisions to benefit atomic power, including tax credits for zero-emissions energy.

“It’s a game changer,” said John Wagner, director of INL.

The tech sector is jumping in, too, as atomic energy heats up across startups and investors. In 2021, venture capital firms poured $3.4 billion into nuclear energy startups. They’re also pouring money into even more far-out ideas, like nuclear fusion power. Public opinion has also started moving. An April Gallup poll found that 55 percent of Americans favour and 44 percent oppose using atomic energy, the highest levels of support in 10 years.

Wind and Solar Surpass Coal in U.S. power generation, as EIA data cites falling LCOE, clean energy incentives, grid upgrades, and battery storage driving renewables growth, lower emissions, jobs, and less fossil fuel reliance.

Key Points

An EIA-noted milestone where U.S. renewables outproduce coal, driven by lower LCOE, policy credits, and grid upgrades.

✅ EIA data shows wind and solar exceed coal generation

✅ Falling LCOE boosts project viability across the grid

✅ Policies and storage advances strengthen reliability

In a landmark shift for the energy sector, wind and solar power have recently surpassed coal in electricity generation in the United States. This milestone, reported by Warp News, marks a significant turning point in the country’s energy landscape and underscores the growing dominance of renewable energy sources.

A Landmark Achievement

The achievement of wind and solar energy generating more electricity than coal is a landmark moment in the U.S. energy sector. Historically, coal has been a cornerstone of electricity production, providing a substantial portion of the nation's power needs. However, recent data reveals a transformative shift, with renewables surpassing coal for the first time in 130 years, as renewable energy sources, particularly wind and solar, have begun to outpace coal in terms of electricity generation.

The U.S. Energy Information Administration (EIA) reported that in recent months, wind and solar combined produced more electricity than coal, including a record 28% share in April, reflecting a broader trend towards cleaner energy sources. This development is driven by several factors, including advancements in renewable technology, decreasing costs, and a growing commitment to reducing greenhouse gas emissions.

Technological Advancements and Cost Reductions

One of the key drivers behind this shift is the rapid advancement in wind and solar technologies, as wind power surges in the U.S. electricity mix across regions. Improvements in turbine and panel efficiency have significantly increased the amount of electricity that can be generated from these sources. Additionally, technological innovations have led to lower production costs, making wind and solar energy more competitive with traditional fossil fuels.

The cost of solar panels and wind turbines has decreased dramatically over the past decade, making renewable energy projects more economically viable. According to Warp News, the levelized cost of electricity (LCOE) from solar and wind has fallen to levels that are now comparable to or lower than coal-fired power. This trend has been pivotal in accelerating the transition to renewable energy sources.

Policy Support and Investment

Government policies and incentives have also played a crucial role in supporting the growth of wind and solar energy, with wind now the most-used renewable electricity source in the U.S. helping drive deployment. Federal and state-level initiatives, such as tax credits, subsidies, and renewable energy mandates, have encouraged investment in clean energy technologies. These policies have provided the financial and regulatory support necessary for the expansion of renewable energy infrastructure.

The Biden administration’s focus on addressing climate change and promoting clean energy has further bolstered the transition. The Infrastructure Investment and Jobs Act and the Inflation Reduction Act, among other legislative efforts, have allocated significant funding for renewable energy projects, grid modernization, and research into advanced technologies.

Environmental and Economic Implications

The surpassing of coal by wind and solar energy has significant environmental and economic implications, building on the milestone when renewables became the second-most prevalent U.S. electricity source in 2020 and set the stage for further gains. Environmentally, it represents a major step forward in reducing carbon emissions and mitigating climate change. Coal-fired power plants are among the largest sources of greenhouse gases, and transitioning to cleaner energy sources is essential for meeting climate targets and improving air quality.

Economically, the shift towards wind and solar energy is creating new opportunities and industries. The growth of the renewable energy sector is generating jobs in manufacturing, installation, and maintenance. Additionally, the decreased reliance on imported fossil fuels enhances energy security and stabilizes energy prices.

Challenges and Future Outlook

Despite the progress, there are still challenges to address. The intermittency of wind and solar power requires advancements in energy storage and grid management to ensure a reliable electricity supply. Investments in battery storage technologies and smart grid infrastructure are crucial for overcoming these challenges and integrating higher shares of renewable energy into the grid.

Looking ahead, the trend towards renewable energy is expected to continue, with renewables projected to soon provide about one-fourth of U.S. electricity as deployment accelerates, driven by ongoing technological advancements, supportive policies, and a growing commitment to sustainability. As wind and solar power become increasingly cost-competitive and efficient, their role in the U.S. energy mix will likely expand, further displacing coal and other fossil fuels.

Conclusion

The surpassing of coal by wind and solar energy in U.S. electricity generation is a significant milestone in the transition to a cleaner, more sustainable energy future. This achievement highlights the growing importance of renewable energy sources and the success of technological advancements and supportive policies in driving this transition. As the U.S. continues to invest in and develop renewable energy infrastructure, the move away from coal represents a crucial step towards achieving environmental goals and fostering economic growth in the clean energy sector.

Gaza Electricity Crisis drives severe power cuts in the Gaza Strip, as Hamas-PA tensions and Mahmoud Abbas's supply reductions under blockade spur fuel shortages, hospital strain, and soaring demand for batteries, LED lights, and generators.

Key Points

A prolonged Gaza power shortage from politics, blockade, and fuel cuts, disrupting daily life, hospitals, and water.

✅ Demand surges for batteries, LED lights, and generators

✅ PA cuts to Israel-supplied power deepen shortages

✅ Hospitals, water, and sanitation face critical strain

In Imad Shlayl’s electronics shop in Gaza City, the customers crowding his store are interested in only two products: LED lights and the batteries to power them.

In the already impoverished Gaza Strip, residents have learned to adapt to the fact that electricity is only available for between two and four hours a day.

But fresh anger was sparked when availability was cut further last month, at the request of the Palestinian president, Mahmoud Abbas, in an escalation of his conflict with Hamas, the Islamist group.

The shortages have defined how people live their lives, echoing Europe’s energy crisis in other regions: getting up in the middle of the night, if there is power, to run washing machines or turn on water pumps.

Only the wealthy few have frequent, long-lasting access to electricity, even as U.S. brownout risks highlight grid fragility, to power lights and fans and fridges, televisions and wifi routers, in Gaza’s stifling summer heat.

“We used to sell all sorts of things,” says Shlayl. “But it’s different these days. All we sell is batteries and chargers. Because the crisis is so deep we are selling 100 batteries a day when normally we would sell 20.”

Gaza requires 430 megawatts of power to meet daily demand, but receives only half that. Sixty megawatts are supplied by its solitary power station, now short on fuel, while the rest is provided through the Israel’s power sector and funded by Abbas’s West Bank-based Palestinian Authority (PA).

Abbas’s move to cut supplies to Gaza, which is already under a joint Israeli and Egyptian blockade – now in its 11th year – has quickly made him a hate figure among many Gazans, who question why he is punishing 2 million fellow Palestinians in what appears to be an attempt to force Hamas to relinquish control of the territory.

Though business is good for Shlayl, he is angry at the fresh shortages faced by Gazans which, as pandemic power shut-offs elsewhere have shown, affect all areas of life, from hospital emergency wards to clean water supplies.

“I’ve not done anything to be punished by anyone. It is the worst I can remember but we are expecting it to get worse and worse,” he said. “Not just electricity, but other things as well. We are in a very deep descent.”

As well as cutting electricity, the PA has cut salaries for its employees in Gaza by upwards of 30% , prompting thousands to protest on the streets of Gaza city.

Residents also blame Abbas for a backlog in processing the medical referral process for those needing to travel out of Gaza for treatment, although who is at fault in that issue is less clear cut.

The problems facing Gaza – where high levels of unemployment are endemic – is most obvious in the poorest areas.

In Gaza City’s al-Shati refugee camp, home to the head of Hamas’s political bureau, Ismail Haniyeh, whole housing blocks were dark, while in others only a handful of windows were weakly illuminated.

In the one-room kiosk selling pigeons and chickens that he manages, just off the camp’s main market, Ayman Nasser, 32, is sitting on the street with his friends in search of a sea breeze.

His face is illuminated by the light of his mobile phone. He has one battery-powered light burning in his shop.

“Part of the problem is that we don’t have any news. Who should we blame for this? Hamas, Israelis, Abbas?” he said.

His friend, Ashraf Kashqin, interrupts: “It is all connected to politics, but it is us who is getting played by the two sides.”

If there is a question that all the Palestinians in Gaza are asking, it is what the ageing and remote Abbas hopes to achieve, a dynamic also seen in Lebanon’s electricity disputes, not least whether he hopes the cuts will lead to an insurrection against Hamas following demonstrations linked to the power supply in January.

While a senior official in the Fatah-led government on the West Bank said last month that the aim behind the move by the PA – which has been paying $12m (£9m) a month for the electricity Israel supplies to Gaza – was to “dry up Hamas’s financial resources”, others are dubious about the timing, the motive and the real impact.

Among them are human rights groups, such as Amnesty International, who have warned it could turn Gaza’s long-running crisis into a major disaster already hitting hospitals and waste treatment plants.

“For 10 years the siege has unlawfully deprived Palestinians in Gaza of their most basic rights and necessities. Under the burden of the illegal blockade and three armed conflicts, the economy has sharply declined and humanitarian conditions have deteriorated severely. The latest power cuts risk turning an already dire situation into a full-blown humanitarian catastrophe,” said Magdalena Mughrabi, of the group.

Then there is the question of timing. “Abbas is probably the only one who knows why he is doing this to Gaza,” adds Mohameir Abu Sa’da, a political science professor at Al Azhar University and analyst.

“I honestly don’t buy what he has been saying for the last three months: that he will take exceptional measures against Hamas to put pressure on it to give up control of the Gaza Strip.

Ontario Hydro Rate Relief Plan delivers short-term electricity bill cuts, while leaked cabinet forecasts show inflation-linked hikes, borrowing costs, and a Clean Energy Adjustment under the province's long-term energy plan.

Key Points

A provincial plan that cuts bills now but defers costs, projecting rate hikes and adding a Clean Energy Adjustment.

✅ 25% cut now, after 8% HST relief; extra 17% reduction applied.

✅ Forecast: inflation-linked hikes later; borrowing adds long-term costs.

✅ Clean Energy Adjustment line to repay deferred system costs.

The short-term gain of a 25 per cent hydro rate cut this summer could lead to long-term pain as a leaked cabinet document forecasts prices jumping again in five years.

In the briefing materials leaked and obtained by the Progressive Conservatives, rates will start rising 6.5 per cent a year in 2022 and top out at 10.5 per cent in 2028, when average monthly bills hit $215.

That would be up from $123 this year once the rate cut — the subject of long-awaited legislation to lower electricity rates unveiled Thursday by Energy Minister Glenn Thibeault — takes full effect. There will be another 17-per-cent cut in addition to the 8 per cent taken off bills in January when the provincial portion of the HST was waived.

The leaked papers overshadowed Thibeault’s efforts to tout the price break, which will be followed with four years of hydro rate increases at 2 per cent, roughly the rate of inflation.

Thibeault charged that the Conservatives used an “outdated” document to distract from the fact that they are the only major party without a plan for dealing with skyrocketing hydro rates, with a year to go until next June’s provincial election.

“It’s not a coincidence,” he told reporters, denying any plans for an eventual 10.5-per-cent rate hike and promising the government’s new long-term energy plan, due in a few months, will have better numbers.

“We are working hard right now to continue to pull costs out of the system.”

Opposition parties said the Liberal plan doesn’t deal with the underlying problems that have made electricity expensive and simply borrows money to spread the costs over a longer period of time, with $25 billion in interest charges over 30 years.

Some observers also noted that a deal with Quebec would not reduce hydro bills, highlighting concerns about lasting affordability.

“The price of electricity is going to skyrocket after the next election,” warned Conservative MPP Todd Smith (Prince Edward—Hastings).

“The government isn’t being honest with the people of Ontario when it comes to the price of electricity.”

The documents show average monthly bills peaking at $231 in the year 2047, before falling back to $210 the following year once the 30 years of interest payments are over.

Conservative sources say they obtained the papers stamped “confidential cabinet document” from a whistleblower after Thibeault’s rate cut plan was presented to cabinet ministers at a meeting in early March.

There is no date on the document, which the energy minister alternately dismissed as “inaccurate” or possibly one of many that have been prepared with different options in mind.

“We’ve had hundreds of briefings with hundreds of documents … I can’t comment on one graph when we’ve been looking at hundreds of scenarios.”

New Democrats, who have proposed a scheme to cut rates, if elected, also called the government plan an election ploy with Liberals lagging in the polls.

“We’re going to take on a huge debt so (Premier) Kathleen Wynne can look good on the hustings in the next few months, and for decades we’re going to pay for it,” said MPP Peter Tabuns (Toronto-Danforth).

Thibeault acknowledged the Liberal plan will start repaying borrowed money in the mid- or late 2020s and it will show up separately on hydro bills as the “Clean Energy Adjustment”, a kind of electricity recovery rate that could raise costs.
