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.

IAEA Nuclear Reactor Simulators enable virtual nuclear power plant training on IPWR/PWR systems, load-following operations, baseload dynamics, and turbine coupling, supporting advanced reactor education, flexible grid integration, and low-carbon electricity skills development during remote learning.

Key Points

IAEA Nuclear Reactor Simulators are tools for training on reactor operations, safety, and flexible power management.

✅ Simulates IPWR/PWR systems with real-time parameter visualization.

✅ Practices load-following, baseload, and grid flexibility scenarios.

✅ Supports remote training on safety, controls, and turbine coupling.

Students and professionals in the nuclear field are making use of learning opportunities during lockdown made necessary by the Covid-19 pandemic, drawing on IAEA low-carbon electricity lessons for the future.

Requests to use the International Atomic Energy Agency’s (IAEA’s) basic principle nuclear reactor simulators have risen sharply in recent weeks, IAEA said on 1 May, as India takes steps to get nuclear back on track. New users will have the opportunity to learn more about operating them.

“This suite of nuclear power plant simulators is part of the IAEA education and training programmes on technology development of advanced reactors worldwide. [It] can be accessed upon request by interested parties from around the world,” said Stefano Monti, head of the IAEA’s Nuclear Power Technology Development Section.

Simulators include several features to help users understand fundamental concepts behind the behaviour of nuclear plants and their reactors. They also provide an overview of how various plant systems and components work to power turbines and produce low-carbon electricity, while illustrating roles beyond electricity as well.

In the integral pressurised water reactor (IPWR) simulator, for instance, a type of advanced nuclear power design, users can navigate through several screens, each containing information allowing them to adjust certain variables. One provides a summary of reactor parameters such as primary pressure, flow and temperature. Another view lays out the status of the reactor core.

The “Systems” screen provides a visual overview of how the plant’s main systems, including the reactor and turbines, work together. On the “Controls” screen, users can adjust values which affect reactor performance and power output.

This simulator provides insight into how the IPWR works, and also allows users to see how the changes they make to plant variables alter the plant’s operation. Operators can also perform manoeuvres similar to those that would take place in the course of real plant operations e.g. in load following mode.

“Currently, most nuclear plants operate in ‘baseload’ mode, continually generating electricity at their maximum capacity. However, there is a trend of countries, aligned with green industrial revolution strategies, moving toward hybrid energy systems which incorporate nuclear together with a diverse mix of renewable energy sources. A greater need for flexible operations is emerging, and many advanced power plants offer standard features for load following,” said Gerardo Martinez-Guridi, an IAEA nuclear engineer who specialises in water-cooled reactor technology.

Prospective nuclear engineers need to understand the dynamics of the consequences of reducing a reactor’s power output, for example, especially in the context of next-generation nuclear systems and emerging grids, and simulators can help students visualise these processes, he noted.

“Many reactor variables change when the power output is adjusted, and it is useful to see how this occurs in real-time,” said Chirayu Batra, an IAEA nuclear engineer, who will lead the webinar on 12 May.

“Users will know that the operation is complete once the various parameters have stabilised at their new values.”

Observing and comparing the parameter changes helps users know what to expect during a real power manoeuvre, he added.

Great British Energy could cut UK electricity costs via public ownership, investing in clean energy like wind, solar, tidal, and nuclear, curbing windfall profits, stabilizing bills, and reinvesting returns through a state-backed generator.

Key Points

A proposed state-backed UK generator investing in clean power to cut costs and return gains to taxpayers.

✅ Publicly owned investment in wind, solar, tidal, and nuclear

✅ Cuts electricity bills by reducing generators' windfall profits

✅ Funded via bonds or asset buyouts; non-profit operations

A publicly owned electricity generation firm could save Britons nearly £21bn a year, according to new analysis that bolsters Labour’s case to launch a national energy company if the party gains power.

Thinktank Common Wealth has calculated that the cost of generating electricity to power homes and businesses could be reduced by £20.8bn or £252 per household a year under state ownership, according to a report seen by the Guardian.

The Labour leader, Keir Starmer, has committed to creating “a publicly owned national champion in clean energy” named Great British Energy.

Starmer is yet to lay out the exact structure of the mooted company, although he has said it would not involve nationalising existing assets, or become involved in the transmission grid or retail supply of energy.

Starmer instead hopes to create a state-backed entity that would invest in clean energy – wind, solar, tidal, nuclear, large-scale storage and other emerging technologies – creating jobs and ensuring windfalls from the growth in low carbon power feed back to the government.

The Common Wealth report, which analysed scenarios for reforming the electricity market, said that a huge saving on electricity costs could be made by buying out assets such as wind, solar and biomass generators on older contracts and running them on a non-profit basis. Funding the measure could require a government bond issuance, or some form of compulsory purchase process.

Last year the government attempted to get companies operating low carbon generators, including nuclear power plants, on older contracts to switch to contracts for difference (CfD), allowing any outsized profits to flow back to taxpayers. However, the government later decided to tax eligible firms through the electricity generator levy instead.

The Common Wealth study concluded that a publicly owned low carbon energy generator would best deliver on Britain’s climate and economic goals, would eliminate windfall profits made by generators and would cut household bills significantly.

MPs and campaigners have argued that Britain’s energy companies should be nationalised since the energy crisis, even as coal-free records have multiplied and renewables still need more support, which has resulted in North Sea oil and gas producers and electricity generators making windfall profits, and a string of retail suppliers collapsing, costing taxpayers billions. Detractors of nationalisation in energy argue it can stifle innovation and expose taxpayers to huge financial risks.

Common Wealth pointed out that more than 40% of the UK’s offshore wind generation capacity was publicly owned by overseas national entities, meaning the benefits of high electricity prices linked to the war in Ukraine had flowed back to other governments.

The study found the publicly owned generator model would create more savings than other options, including a drive for voluntary CfDs; splitting the generation market between low carbon and fossil fuel sources at a time when wind and solar have outproduced nuclear, and a “single buyer model” with nationalised retail suppliers.

Ontario Nuclear Power Costs highlight LCOE, capex, refurbishment outlays, and waste management, compared with renewables, grid reliability, and emissions targets, informing Australia and Peter Dutton on feasibility, timelines, and electricity prices.

Key Points

They include high capex and LCOE from refurbishments and waste, offset by reliable, low-emission baseload.

✅ Refurbishment and maintenance drive lifecycle and LCOE variability.

✅ High capex and long timelines affect consumer electricity prices.

✅ Low emissions, but waste and safety compliance add costs.

Australian opposition leader Peter Dutton recently lauded Canada’s use of nuclear power as a model for Australia’s energy future. His praise comes as part of a broader push to incorporate nuclear energy into Australia’s energy strategy, which he argues could help address the country's energy needs and climate goals. However, the question arises: Is Ontario’s experience with nuclear power as cost-effective as Dutton suggests?

Dutton’s endorsement of Canada’s nuclear power strategy highlights a belief that nuclear energy could provide a stable, low-emission alternative to fossil fuels. He has pointed to Ontario’s substantial reliance on nuclear power, and the province’s exploration of new large-scale nuclear projects, as an example of how such an energy mix might benefit Australia. The province’s energy grid, which integrates a significant amount of nuclear power, is often cited as evidence that nuclear energy can be a viable component of a diversified energy portfolio.

The appeal of nuclear power lies in its ability to generate large amounts of electricity with minimal greenhouse gas emissions. This characteristic aligns with Australia’s climate goals, which emphasize reducing carbon emissions to combat climate change. Dutton’s advocacy for nuclear energy is based on the premise that it can offer a reliable and low-emission option compared to the fluctuating availability of renewable sources like wind and solar.

However, while Dutton’s enthusiasm for the Canadian model reflects its perceived successes, including recent concerns about Ontario’s grid getting dirtier amid supply changes, a closer look at Ontario’s nuclear energy costs raises questions about the financial feasibility of adopting a similar strategy in Australia. Despite the benefits of low emissions, the economic aspects of nuclear power remain complex and multifaceted.

In Ontario, the cost of nuclear power has been a topic of considerable debate. While the province benefits from a stable supply of electricity due to its nuclear plants, studies warn of a growing electricity supply gap in coming years. Ontario’s experience reveals that nuclear power involves significant capital expenditures, including the costs of building reactors, maintaining infrastructure, and ensuring safety standards. These expenses can be substantial and often translate into higher electricity prices for consumers.

The cost of maintaining existing nuclear reactors in Ontario has been a particular concern. Many of these reactors are aging and require costly upgrades and maintenance to continue operating safely and efficiently. These expenses can add to the overall cost of nuclear power, impacting the affordability of electricity for consumers.

Moreover, the development of new nuclear projects, as seen with Bruce C project exploration in Ontario, involves lengthy and expensive construction processes. Building new reactors can take over a decade and requires significant investment. The high initial costs associated with these projects can be a barrier to their economic viability, especially when compared to the rapidly decreasing costs of renewable energy technologies.

In contrast, the cost of renewable energy has been falling steadily, even as debates over nuclear power’s trajectory in Europe continue, making it a more attractive option for many jurisdictions. Solar and wind power, while variable and dependent on weather conditions, have seen dramatic reductions in installation and operational costs. These lower costs can make renewables more competitive compared to nuclear energy, particularly when considering the long-term financial implications.

Dutton’s praise for Ontario’s nuclear power model also overlooks some of the environmental and logistical challenges associated with nuclear energy. While nuclear power generates low emissions during operation, it produces radioactive waste that requires long-term storage solutions. The management of nuclear waste poses significant environmental and safety concerns, as well as additional costs for safe storage and disposal.

Additionally, the potential risks associated with nuclear power, including the possibility of accidents, contribute to the complexity of its adoption. The safety and environmental regulations surrounding nuclear energy are stringent and require continuous oversight, adding to the overall cost of maintaining nuclear facilities.

As Australia contemplates integrating nuclear power into its energy mix, it is crucial to weigh these financial and environmental considerations. While the Canadian model provides valuable insights, the unique context of Australia’s energy landscape, including its existing infrastructure, energy needs, and the costs of scrapping coal-fired electricity in comparable jurisdictions, must be taken into account.

In summary, while Peter Dutton’s endorsement of Canada’s nuclear power model reflects a belief in its potential benefits for Australia’s energy strategy, the cost-effectiveness of Ontario’s nuclear power experience is more nuanced than it may appear. The high capital and maintenance costs associated with nuclear energy, combined with the challenges of managing radioactive waste and ensuring safety, present significant considerations. As Australia evaluates its energy future, a comprehensive analysis of both the benefits and drawbacks of nuclear power will be essential to making informed decisions about its role in the country’s energy strategy.

Bruce Power Unit 6 refurbishment replaces major reactor components, shifting supply to hydroelectric and natural gas, sustaining Ontario jobs, extending plant life to 2064, and managing radioactive waste along Lake Huron, on-time and on-budget.

Key Points

A 4-year, $2.1B reactor overhaul within a 13-year, $13B program to extend plant life to 2064 and support Ontario jobs.

✅ Unit 6 offline 4 years; capacity shift to hydro and gas

✅ Part of 13-year, $13B program; extends life to 2064

✅ Creates jobs; manages radioactive waste at Lake Huron

The world’s largest nuclear fleet, became a little smaller Monday morning. Bruce Power has began the process to take Unit 6 offline to begin a $2.1 billion project, supported by manufacturing contracts with key suppliers, to replace all the major components of the reactor.

The reactor, which produces enough electricity to power 750,000 homes and reflects higher output after upgrades across the site, will be out of service for the next four years.

In its place, hydroelectric power and natural gas will be utilized more.

Taking Unit 6 offline is just the “official” beginning of a 13-year, $13-billion project to refurbish six of Bruce Power’s eight nuclear reactors, as Ontario advances the Pickering B refurbishment as well on its grid.

Work to extend the life of the nuclear plant started in 2016, and the company recently marked an operating record while supporting pandemic response, but the longest and hardest part of the project - the major component replacement - begins now.

“The Unit 6 project marks the next big step in a long campaign to revitalize this site,” says Mike Rencheck, Bruce Power’s president and CEO.

The overall project is expected to last until 2033, and mirrors life extensions at Pickering supporting Ontario’s zero-carbon goals, but will extend the life of the nuclear plant until 2064.

Extending the life of the Bruce Power nuclear plant will sustain 22,000 jobs in Ontario and add $4 billion a year in economic activity to the province, say Bruce Power officials.

About 2,000 skilled tradespeople will be required for each of the six reactor refurbishments - 4,200 people already work at the sprawling nuclear plant near Kincardine.

It will also mean tons of radioactive nuclear waste will be created that is currently stored in buildings on the Bruce Power site, along the shores of Lake Huron.

Bruce Power restarted two reactors back in 2012, and in later years doubled a PPE donation to support regional health partners. That project was $2-billion over-budget, and three years behind schedule.

Bruce Power officials say this refurbishment project is currently on-time and on-budget.

NERC COVID-19 Grid Security Alert urges utilities to update business continuity plans, assess supply chain risk, and harden cybersecurity against spearphishing, social engineering, and remote-work vulnerabilities to protect the U.S. power grid and critical infrastructure.

Key Points

A notice urging U.S. utilities to fortify pandemic continuity, secure supply chains, and enhance cybersecurity.

✅ Mandates updates to business continuity and pandemic readiness plans

✅ Flags supply chain risks for PPE, electronics, chemicals, and logistics

✅ Warns of spearphishing, social engineering, VPN and remote-work threats

The top U.S. grid security monitor urged power utilities to prepare for the new coronavirus in a rare alert yesterday, adding to a chorus of warnings from federal and private organizations.

The North American Electric Reliability Corp. called for power providers to update business continuity plans in case of a pandemic outbreak and weigh the need to prioritize construction or maintenance projects, including updates on major projects like BC Hydro's Site C, while the COVID-19 virus continues to spread.

NERC is requiring electric utilities to answer questions on their readiness for a possible pandemic, including potential staffing strategies such as on-site sequestering, by March 20, an unusual step that underscores the severity of the threat to U.S. power systems.

The Electricity Information Sharing and Analysis Center, NERC's hub for getting the word out on dangers and vulnerabilities for the grid, also sent out an "all-points bulletin" on Feb. 5 addressing the coronavirus outbreak. That nonpublic document covered "potential supply chain issues stemming from a manufacturing slowdown in Asia," NERC spokeswoman Kimberly Mielcarek said.

Among offering basic hygiene and awareness recommendations, NERC's latest alert also encourages utilities to take stock of resources with supply chains affected by the virus. Because "China and nearby southeast Asian nations" have been impacted, NERC said, the supply chain hits will likely include "electronics, personal protective equipment and sanitation supplies, chemicals, and raw materials." The nonprofit grid overseer also warned of global transportation disruptions.

NERC also recommended utilities be on the lookout for cyberattacks taking advantage of the panic and using "coronavirus-themed opportunistic social engineering attacks" to hack into power companies' networks. Social engineering attacks are when hackers use social interactions to manipulate targets into giving up sensitive information.

"Spearphishing, watering hole, and other disinformation tactics are commonly used to exploit public interest in significant events," the alert said.

Electric utility representatives said they're working on or have already completed some of the steps outlined in NERC's alert, though nuclear plant workers have cited a lack of precautions in some cases.

"At this point, many of our members are activating and/or reviewing their business continuity and preparedness plans to ensure that operations and infrastructure are properly supported," said Tobias Sellier, director of media relations for the American Public Power Association, which represents around 1,400 electric utilities.

The power providers are also collaborating with other utilities such as "water, wastewater and gas," Sellier said.

Stephen Bell, senior director of media and public relations at the National Rural Electric Cooperative Association, said his group's members "have already taken a number of steps recommended by NERC" while continuing to maintain operations.

"Co-ops continue working with local, state and federal stakeholders to remain vigilant and prepared. These preparations include more frequent communications to key stakeholders, updating business continuity plans and monitoring new information from public health officials," said Bell.

Last week the Electricity Subsector Coordinating Council (ESCC), a panel of government and industry officials charged with responding to power-sector emergencies, scheduled a conference call discussing how to protect the grid from disruption if the virus infects system operators. Ohio-based utility American Electric Power Co. said it is limiting public visits, has created a high-level response team and is working to ensure operations can continue, while reinforcing downed power line safety, if the virus keeps spreading (Energywire, March 6).

Scott Aaronson, vice president for security and preparedness of the Edison Electric Institute, which represents major investor-owned utilities, said that the electric sector practices "contingency planning" to deal with unusual situations such as the coronavirus. That means that while the type of emergency may be new, dealing with an emergency situation is not, he said. Aaronson added that many of NERC's recommendations are based on what companies are already doing.

"We have heightened awareness given the circumstances, and we have messaging to employees all the way up and down the chain — from CEOs to frontline workers — that: given this time of heightened awareness and potential vulnerability, we have to practice hygiene both of the personal and cyber variety," said Aaronson.

Aaronson said that the ESCC had another call this week with the departments of Energy and Homeland Security and the Centers for Disease Control and Prevention to stay on top of the issue.

Hacking concerns
In a cybersecurity event yesterday, Lisa Monaco, co-chair of the Aspen Cybersecurity Group and former homeland security adviser during the Obama administration, warned that the coronavirus should be considered a national security threat.

"Frankly, [pandemic] is the thing that kept me up at night amongst many, many things that kept me up at night for four years in the White House," Monaco said.

Monaco went on to say the virus will strain organizations' IT infrastructure as more employees work remotely and households face higher electricity bills, and lead to "potentially more vulnerabilities for bad actors when it comes to cybersecurity."

On Friday, the DHS's Cybersecurity and Infrastructure Security Agency released advice on steps that can be taken to lessen the virus's impact on supply chains and cybersecurity, as well as tips for defending against scams exploiting coronavirus fears.

Cybersecurity firms also have been reporting a dramatic increase in spear-phishing attacks, with hackers reportedly using the coronavirus topic as a lure to trick victims into clicking a malicious link. Whether it's hackers aiming at industries susceptible to shipping disruptions, attacking countries like Italy hit particularly hard by the virus or even masquerading as the World Health Organization, cybercriminals are taking full advantage of the crisis, experts say.

Greg Young, vice president of cybersecurity at Trend Micro, said businesses should continue to expect an increase in targeted phishing attacks.

"With a large majority of businesses switching to a work-from-home model and less emphasis on in-person meetings, we also anticipate that malicious actors will start to impersonate digital tools such as 'free' remote conferencing services and other cloud computing software," said Young.

Working from home can be especially risky, as often home networks are less secure than corporate offices, Young said — meaning a hacker aiming to get into an enterprise network could find an "easier attack path" from a home office.

The Department of Energy is asking employees to make sure they can work remotely when needed, even as some agencies set limits with EPA telework policy, including updating security questions and asking those with government-furnished laptops to be sure they have a VPN, or virtual private network, account. In a post added this week to the agency's website, Chief Information Officer Rocky Campione said the department over the next two weeks will be initiating steps to ensure there is adequate network capacity to carry out DOE's work.

"Ensuring the continued operations of the department's many varied missions requires diligence," Campione said.
