Duke Energy has asked federal regulators to allow a temporary cooling-water system at the Allen power plant in Gaston County, allowing the plant to operate at full tilt through the late-summer drought.

Allen pulls millions of gallons a day from Lake Wylie and uses it to condense steam inside the coal-fueled plant. The warmed water is then piped into a canal where it cools before flowing into the South Fork of the Catawba River.

Drought makes it harder to cool the discharged water, which must be below 102 degrees before flowing back into the lake. Little water flows into Wylie from tributaries and Duke releases less water from its dam, reducing the circulation of fresh water in the lake. That problem could limit the amount of power that Allen, one of Duke's largest plants at 1,140 megawatts, can produce.

Demand for electricity is highest in summer, when air conditioners kick in around the region. Duke's solution: Draw 86 million more gallons a day from the lake to the canal. The 11 percent increase of cooler water would further dilute the warm discharge water. The utility applied Friday to the Federal Energy Regulatory Commission for permission to use the temporary system through September.

Without it, said Joe Hall, Duke's lake-services director, Allen might have to curtail its operations. The N.C. Division of Water Quality, which polices Duke's discharges to the lake, has already approved the request.

Next year, Duke plans to install a permanent system to bring in more cooling water each summer from July through September, allowing the plant to make more power. Since the drought took hold more than a year ago, Duke has sharply reduced operation of its hydroelectric power plants to conserve water in its lakes.

Earlier this year, the utility reconfigured its McGuire nuclear plant to allow Lake Norman to be reduced three feet below its previous minimum level. Duke also took an option to buy up to 520 megawatts of power from a natural gas-powered plant in South Carolina if its own plants can't run.

IAEA Reviews Belarus’ Nuclear Power Infrastructure Development

Belarus Nuclear Power Infrastructure Review evaluates IAEA INIR Phase 3 readiness at Ostrovets NPP, VVER-1200 reactors, legal and regulatory framework, commissioning, safety, emergency preparedness, and energy diversification in a low-carbon program.

 

Key Points

An IAEA INIR Phase 3 assessment of Belarus readiness to commission and operate the Ostrovets NPP with VVER-1200 units.

✅ Reviews legal, regulatory, and institutional arrangements

✅ Confirms Phase 3 readiness for safe commissioning and operation

✅ Highlights good practices in peer reviews and emergency planning

 

An International Atomic Energy Agency (IAEA) team of experts today concluded a 12-day mission to Belarus to review its infrastructure development for a nuclear power programme. The Integrated Nuclear Infrastructure Review (INIR) was carried out at the invitation of the Government of Belarus.

Belarus, seeking to diversify its energy production with a reliable low-carbon source, and aware of the benefits of energy storage for grid flexibility, is building its first nuclear power plant (NPP) at the Ostrovets site, about 130 km north-west of the capital Minsk. The country has engaged with the Russian Federation to construct and commission two VVER-1200 pressurised water reactors at this site and expects the first unit to be connected to the grid this year.

The INIR mission reviewed the status of nuclear infrastructure development using the Phase 3 conditions of the IAEA’s Milestones Approach. The Ministry of Energy of Belarus hosted the mission.

The INIR team said Belarus is close to completing the required nuclear power infrastructure for starting the operation of its first NPP. The team made recommendations and suggestions aimed at assisting Belarus in making further progress in its readiness to commission and operate it, including planning for integration with variable renewables, as advances in new wind turbines are being deployed elsewhere to strengthen the overall energy mix.

“This mission marks an important step for Belarus in its preparations for the introduction of nuclear power,” said team leader Milko Kovachev, Head of the IAEA’s Nuclear Infrastructure Development Section. “We met well-prepared, motivated and competent professionals ready to openly discuss all infrastructure issues. The team saw a clear drive to meet the objectives of the programme and deliver benefits to the Belarusian people, such as supporting the country’s economic development, including growth in EV battery manufacturing sectors.”

The team comprised one expert from Algeria and two experts from the United Kingdom, as well as seven IAEA staff. It reviewed the status of 19 nuclear infrastructure issues using the IAEA evaluation methodology for Phase 3 of the Milestones Approach, noting that regional integration via an electricity highway can shape planning assumptions as well. It was the second INIR mission to Belarus, who hosted a mission covering Phases 1 and 2 in 2012.

Prior to the latest mission, Belarus prepared a Self-Evaluation Report covering all infrastructure issues and submitted the report and supporting documents to the IAEA.

The team highlighted areas where further actions would benefit Belarus, including the need to improve institutional arrangements and the legal and regulatory framework, drawing on international examples of streamlined licensing for advanced reactors to ensure a stable and predictable environment for the programme; and to finalize the remaining arrangements needed for sustainable operation of the nuclear power plant.

The team also identified good practices that would benefit other countries developing nuclear power in the areas of programme and project coordination, the use of independent peer reviews, cooperation with regulators from other countries, engagement with international stakeholders and emergency preparedness, and awareness of regional initiatives such as new electricity interconnectors that can enhance system resilience.

Mikhail Chudakov, IAEA Deputy Director General and Head of the Department of Nuclear Energy attended the Mission’s closing meeting. “Developing the infrastructure required for a nuclear power programme requires significant financial and human resources, and long lead times for preparation and the approval of major transmission projects that support clean power flows, and the construction activities,” he said. “Belarus has made commendable progress since the decision to launch a nuclear power programme 10 years ago.”

“Hosting the INIR mission, Belarus demonstrated its transparency and genuine interest to receive an objective professional assessment of the readiness of its nuclear power infrastructure for the commissioning of the country’s first nuclear power plant,” said Mikhail Mikhadyuk, Deputy Minister of Energy of the Republic of Belarus. ”The recommendations and suggestions we received will be an important guidance for our continuous efforts aimed at ensuring the highest level of safety and reliability of the Belarusian NPP."

Neo-Nazi, woman accused of plotting 'hate-fueled attacks' on power stations, federal complaint says

Baltimore Substation Attack Plot highlights alleged neo-Nazi plans targeting electrical substations and the power grid, as FBI and DHS warn of domestic extremism threats to critical infrastructure, with arrests in Maryland disrupting potential sniper attacks.

 

Key Points

An alleged extremist plot to disable Baltimore's power grid by shooting substations, thwarted by federal arrests.

✅ Two suspects charged in Maryland conspiracy

✅ Targets included five substations around Baltimore

✅ FBI cites domestic extremism threat to infrastructure

 

A neo-Nazi in Florida and a Maryland woman conspired to attack several electrical substations in the Baltimore area, federal officials say.

Sarah Beth Clendaniel and Brandon Clint Russell were arrested and charged in a conspiracy to disable the power grid by shooting out substations via "sniper attacks," according to a criminal complaint from the U.S. Attorney's Office for the District of Maryland.

Clendaniel allegedly said she wanted to "completely destroy this whole city" and was planning to target five substations situated in a "ring" around Baltimore, the complaint said. Russell is part of a violent extremist group that has cells in multiple states, and he previously planned to attack critical infrastructure in Florida, the complaint said.

"This planned attack threatened lives and would have left thousands of Marylanders in the cold and dark," Maryland U.S. Attorney Erek Barron said in a press release. "We are united and committed to using every legal means necessary to disrupt violence, including hate-fueled attacks."

The news comes as concerns grow about an increase in targeted substation attacks on U.S. substations tied to domestic extremism.

 

What to know about substation attacks

Federal data shows vandalism and suspicious activities at electrical facilities soared nationwide last year, and cyber actors have accessed utilities' control rooms as well.

At the end of the year, attacks or potential attacks were reported on more than a dozen substations and one power plant across five states, and Symantec documented Russia-linked Dragonfly activity targeting the energy sector earlier. Several involved firearms.

In December, targeted attacks on substations in North Carolina left tens of thousands without power amid freezing temperatures, spurring renewed focus on protecting the U.S. power grid among officials. The FBI is investigating.

Vandalism at facilities in Washington left more than 21,000 without electricity on Christmas Day, even as hackers breached power-plant systems in other states. Two men were arrested, and one told police he planned to disrupt power to commit a burglary.

The Department of Homeland Security last year said domestic extremists had been developing "credible, specific plans" since at least 2020 and would continue to "encourage physical attacks against electrical infrastructure," and the U.S. government has condemned Russia for power grid hacking as well.

Last February, three neo-Nazis pleaded guilty to federal crimes related to a scheme to attack the grid with rifles, with each targeting a substation in a different region of the U.S., even as reports that Russians hacked into US electric utilities drew widespread attention.

Groups clash over NH hydropower project

Northern Pass Hydropower Project Rehearing faces review by New Hampshire's Site Evaluation Committee as Eversource seeks approval for a 192-mile transmission line, citing energy cost relief, while Massachusetts eyes Central Maine Power as an alternative.

 

Key Points

A review of Eversource's halted NH transmission plan, weighing impacts, costs, and alternatives.

✅ SEC denied project, Eversource seeks rehearing

✅ 192-mile line to bring Canadian hydropower to NE

✅ Alternative bids include Central Maine Power corridor

 

Groups supporting and opposing the Northern Pass hydropower project in New Hampshire filed statements Friday in advance of a state committee’s meeting next week on whether it should rehear the project.

The Site Evaluation Committee rejected the transmission proposal last month over concerns about potential negative impacts. It is scheduled to deliberate Monday on Eversource’s request for a rehearing.

The $1.6 billion project would deliver hydropower from Canada, including Hydro-Quebec exports, to customers in southern New England through a 192-mile transmission line in New Hampshire.

If the Northern Pass project fails to ultimately win New Hampshire approval, the Massachusetts Department of Energy Resources has announced it will begin negotiating with a team led by Central Maine Power Co. for a $950 million project through a 145-mile Maine transmission line as an alternative.

Separately, construction later began on the disputed $1 billion electricity corridor despite ongoing legal and political challenges.

The Business and Industry Association voted last month to endorse the project after remaining neutral on it since it was first proposed in 2010. A letter sent to the committee Friday urges it to resume deliberations. The association said it is concerned about the severe impact the committee’s decision could have on New Hampshire’s economic future, even as Connecticut overhauls electricity market structure across New England.

“The BIA believes this decision was premature and puts New Hampshire’s economy at risk,” organization President Jim Roche wrote. “New Hampshire’s electrical energy prices are consistently 50-60 percent higher than the national average. This has forced employers to explore options outside New Hampshire and new England to obtain lower electricity prices. Businesses from outside New Hampshire and others now here are reversing plans to grow in New Hampshire due to the Site Evaluation Committee’s decision.”

The International Brotherhood of Electrical Workers and the Coos County Business and Employers Group also filed a statement in support of rehearing the project.

The Society to Protect New Hampshire Forests, which is opposed to the project, said Eversource’s request is premature because the committee hasn’t issued a final written decision yet. It also said Eversource hasn’t proven committee members “made an unlawful or unreasonable decision or mistakenly overlooked matters it should have considered.”

As part of its request for reconsideration, Eversource said it is offering up to $300 million in reductions to low-income and business customers in the state.

It also is offering to allocate $95 million from a previously announced $200 million community fund — $25 million to compensate for declining property values, $25 million for economic development and $25 million to promote tourism in affected areas. Another $20 million would fund energy efficiency programs.

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

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

 

Key Points

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

✅ Focuses on rates, subsidies, and consumer affordability

✅ Balances nuclear baseload, renewables, and Quebec hydro imports

✅ Emphasizes grid transmission, consultation, and conservation

 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Alberta Introduces New Electricity Rules

Alberta Rate of Last Resort streamlines electricity regulations to stabilize the default rate, curb price volatility, and protect rural communities, low-income households, and seniors while preserving competition in the province's energy market.

 

Key Points

Alberta's Rate of Last Resort sets biennial default electricity prices, curbing volatility and protecting customers.

✅ Biennial default rate to limit price spikes

✅ Focus on rural, senior, and low-income customers

✅ Encourages competitive contracts and market stability

 

The Alberta government is overhauling its electricity regulations as part of a market overhaul aimed at reducing spikes in electricity prices for consumers and businesses. The new rules, set to be introduced this spring, are intended to stabilize the default electricity rate paid by many Albertans.


Background on the Rate of Last Resort

Albertans currently have the option to sign up for competitive contracts with electricity providers. These contracts can sometimes offer lower rates than the default electricity rate, officially known as the Regulated Rate Option (RRO). However, these competitive rates can fluctuate significantly. Currently, those unable to secure these contracts or those who are on the default rate are experiencing rising electricity prices and high levels of price volatility.

To address this, the Alberta government is renaming the default rate as the Rate of Last Resort designation (RoLR) under the new framework. This aims to reduce the sense of security that some consumers might associate with the current name, which the government feels is misleading.


Key Changes Under New Regulations

The new regulations, which include proposed market changes that affect pricing, focus on:

  • Price Stabilization: Default electricity rates will be set every two years for each utility provider, providing greater predictability by enabling a consumer price cap and reducing the potential for extreme price swings.
  • Rural and Underserved Communities: The changes are intended to particularly benefit rural Albertans and those on the default rate, including low-income individuals and seniors. These groups often lack access to the competitive rates offered by some providers and have been disproportionately affected by recent price increases.
  • Promoting Economic Stability: The goal is to lower the cost of utilities for all Albertans, leading to overall lower costs of living and doing business. The government anticipates these changes will create a more attractive environment for investment and job creation.


Opposition Views

Critics argue that limiting the flexibility of prices for the default electricity rate could interfere with market dynamics and stifle market competition among providers. Some worry it could ultimately lead to higher prices in the long term. Others advocate directly subsidizing low-income households rather than introducing broad price controls.


Balancing Affordability and the Market

The Alberta government maintains that the proposed changes will strike a balance between ensuring affordable electricity for vulnerable Albertans and preserving a competitive energy market. Provincial officials emphasize that the new regulations should not deter consumers from seeking out competitive rates if they choose to.


The Path Ahead

The new electricity regulations are part of the Alberta government's broader Affordable Utilities Program, alongside electricity policy changes across the province. The legislation is expected to be introduced and debated in the provincial legislature this spring with the potential of coming into effect later in the year. Experts expect these changes will significantly impact the Alberta electricity market and ignite further discussion about how best to manage rising utility costs for consumers and businesses.

The Cool Way Scientists Turned Falling Raindrops Into Electricity

Raindrop Triboelectric Energy Harvesting converts falling water into electricity using Teflon (PTFE) on indium tin oxide and an aluminum electrode, forming a transient water bridge; a low frequency nanogenerator for renewable, static electricity harvesting.

 

Key Points

A method using PTFE, ITO, and an aluminum electrode to turn raindrop impacts into low frequency electrical power.

✅ PTFE on ITO boosts charge transfer efficiency.

✅ Water bridge links electrodes for rapid discharge.

✅ Low frequency output suits continuous energy harvesting.

 

Scientists at the City University of Hong Kong have used a Teflon-coated surface and a phenomenon called triboelectricity to generate a charge from raindrops. “Here we develop a device to harvest energy from impinging water droplets by using an architecture that comprises a polytetrafluoroethylene [Teflon] film on an indium tin oxide substrate plus an aluminium electrode,” they explain in their new paper in Nature as a step toward cheap, abundant electricity in the long term.

Triboelectricity itself is an old concept. The word means “friction electricity”—from the Greek tribo, to rub or wear down, which is why a diatribe tires you out—and dates back a long, long time. Static electricity is the most famous kind of triboelectric, and related work has shown electricity from the night sky can be harvested as well in niche setups. In most naturally occurring kinds, scientists have studied triboelectric in order to avoid its effects, like explosions inside of grain silos or hospital workers touching off pure oxygen. (Blowing sand causes an electric field, and NASA even worries about static when astronauts eventually land on Mars.)

One of the most studied forms of intentional and useful triboelectric is in systems such as ocean wave generators where the natural friction of waves meets nanogenerators of triboelectric energy. These even already use Teflon, which has natural conductivity that makes it ideal for this job. But triboelectricity is chaotic, and harnessing it generally involves a bunch of complicated, intersecting variables that can vary with the hourly weather. Promises of static electricity charging devices have often been, well, so much hot, sandy wind.

The scientists at City University of Hong Kong used triboelectric ideas to turn falling raindrops into energy. They say previous versions of the same idea were not very efficient, with materials that didn’t allow for high-fidelity transfer of electrical charge. (Many sources of renewable energy aren’t yet as efficient to turn into power, both because of developing technology and because their renewability means even less efficient use could be better than, for example, fossil fuels, and advances in renewable energy storage could help.)

“[A]chieving a high density of electrical power generation is challenging,” the team explains in its paper. “Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low water supply.” Diversifying how power is generated by water sources such as oceans and rivers is good for the existing infrastructure as well as new installations.

The research team found that as simulated raindrops fell on their device, the way the water accumulated and spread created a link between their two electrodes, one Teflon-coated and the other aluminum. This watery de facto wire link closes the loop and allows accumulated energy to move through the system. Because it’s a mechanical setup, it’s not limited to salty seawater, and because the medium is already water, its potential isn’t affected by ambient humidity either.

Raindrop energy is very low frequency, which means this tech joins many other existing pushes to harvest continuously available, low frequency natural energy, including underwater 'kites' that exploit steady currents. To make an interface that increases “instantaneous power density by several orders of magnitude over equivalent devices,” as the researchers say they’ve done here, could represent a major step toward feasibility in triboelectric generation.
