US Power Grid Cyberattacks target utilities and nuclear plants, probing SCADA, ICS, and business networks at sites like Wolf Creek; suspected Russian actors, malware, and spear-phishing trigger DHS and FBI alerts on critical infrastructure resilience.

Key Points

Intrusions on energy networks probing ICS and SCADA, seeking persistence and elevating risks to critical infrastructure.

✅ Wolf Creek nuclear plant targeted; no operational systems breached

✅ Attackers leveraged stolen credentials, malware, and spear-phishing

✅ DHS and FBI issued alerts; utilities enhance cyber resilience

Hackers working for a foreign government recently breached at least a dozen US power plants, including the Wolf Creek nuclear facility in Kansas, according to current and former US officials, sparking concerns the attackers were searching for vulnerabilities in the electrical grid.

The rivals could be positioning themselves to eventually disrupt the nation’s power supply, warned the officials, who noted that a general alert, prompting a renewed focus on protecting the U.S. power grid, was distributed to utilities a week ago. Adding to those concerns, hackers recently infiltrated an unidentified company that makes control systems for equipment used in the power industry, an attack that officials believe may be related.

The chief suspect is Russia, according to three people familiar with the continuing effort to eject the hackers from the computer networks. One of those networks belongs to an ageing nuclear generating facility known as Wolf Creek -- owned by Westar Energy Inc, Great Plains Energy Inc, and Kansas Electric Power Cooperative Inc -- on a lake shore near Burlington, Kansas.

The possibility of a Russia connection is particularly worrying, former and current official s say, because Russian hackers have previously taken down parts of the electrical grid in Ukraine and appear to be testing increasingly advanced tools, including cyber weapons to disrupt power grids, to disrupt power supplies.

The hacks come as international tensions have flared over US intelligence agencies’ conclusion that Russia tried to influence the 2016 presidential election, and amid U.S. government condemnation of Russian power-grid hacking in recent advisories. The US, which has several continuing investigations into Russia’s activities, is known to possess digital weapons capable of disrupting the electricity grids of rival nations.

“We don’t pay attention to such anonymous fakes,” Kremlin spokesman Dmitry Peskov said, in response to a request to comment on alleged Russian involvement.

It was unclear whether President Donald Trump was planning to address the cyber attacks at his meeting on Friday with Russian President Vladimir Putin. In an earlier speech in Warsaw, Trump called out Russia’s “destabilising activities” and urged the country to join “the community of responsible nations.”

The Department of Homeland Security and Federal Bureau of Investigation said they are aware of a potential intrusion in the energy sector. The alert issued to utilities cited activities by hackers since May.

“There is no indication of a threat to public safety, as any potential impact appears to be limited to administrative and business networks,” the government agencies said in a joint statement.

The Department of Energy also said the impact appears limited to administrative and business networks and said it was working with utilities and grid operators to enhance security and resilience.

“Regardless of whether malicious actors attempt to exploit business networks or operational systems, we take any reports of malicious cyber activity potentially targeting our nation’s energy infrastructure seriously and respond accordingly,” the department said in an emailed statement.

Representatives of the National Security Council, the Director of National Intelligence and the Nuclear Regulatory Commission declined to comment. While Bloomberg News was waiting for responses from the government, the New York Times reported that hacks were targeting nuclear power stations.

The North American Electric Reliability Corp, a nonprofit that works to ensure the reliability of the continent’s power system, said it was aware of the incident and was exchanging information with the industry through a secure portal.

“At this time, there has been no bulk power system impact in North America,” the corporation said in an emailed statement.

In addition, the operational controls at Wolf Creek were not pierced, according to government officials, even as attackers accessed utility control rooms elsewhere in the U.S., according to separate reports. “There was absolutely no operational impact to Wolf Creek,” Jenny Hageman, a spokeswoman for the nuclear plant, said in a statement to Bloomberg News.

“The reason that is true is because the operational computer systems are completely separate from the corporate network.”

Determining who is behind an attack can be tricky. Government officials look at the sophistication of the tools, among other key markers, when gauging whether a foreign government is sponsoring cyber activities.

Several private security firms, including Symantec researchers, are studying data on the attacks, but none has linked the work to a particular hacking team or country.

“We don’t tie this to any known group at this point,” said Sean McBride, a lead analyst for FireEye Inc, a global cyber security firm. “It’s not to say it’s not related, but we don’t have the evidence at this point.”

US intelligence officials have long been concerned about the security of the country’s electrical grid. The recent attack, striking almost simultaneously at multiple locations, is testing the government’s ability to coordinate an effective response among several private utilities, state and local officials, and industry regulators.

Specialised teams from Homeland Security and the FBI have been scrambled to help extricate the hackers from the power stations, in some cases without informing local and state officials. Meanwhile, the US National Security Agency is working to confirm the identity of the hackers, who are said to be using computer servers in Germany, Italy, Malaysia and Turkey to cover their tracks.

Many of the power plants are conventional, but the targeting of a nuclear facility adds to the pressure. While the core of a nuclear generator is heavily protected, a sudden shutdown of the turbine can trigger safety systems. These safety devices are designed to disperse excess heat while the nuclear reaction is halted, but the safety systems themselves may be vulnerable to attack.

Homeland Security and the FBI sent out a general warning about the cyber attack to utilities and related parties on June 28, though it contained few details or the number of plants affected. The government said it was most concerned about the “persistence” of the attacks on choke points of the US power supply. That language suggests hackers are trying to establish backdoors on the plants’ systems for later use, according to a former senior DHS official who asked not to be identified.

Those backdoors can be used to insert software specifically designed to penetrate a facility’s operational controls and disrupt critical systems, according to Galina Antova, co-founder of Claroty, a New York firm that specialises in securing industrial control systems.

“We’re moving to a point where a major attack like this is very, very possible,” Antova said. “Once you’re into the control systems -- and you can get into the control systems by hacking into the plant’s regular computer network -- then the basic security mechanisms you’d expect are simply not there.”

The situation is a little different at nuclear facilities. Backup power supplies and other safeguards at nuclear sites are meant to ensure that “you can’t really cause a nuclear plant to melt down just by taking out the secondary systems that are connected to the grid,” Edwin Lyman, a nuclear expert with the Union of Concerned Scientists, said in a phone interview.

The operating systems at nuclear plants also tend to be legacy controls built decades ago and don’t have digital control systems that can be exploited by hackers. Wolf Creek, for example, began operations in 1985. “They’re relatively impervious to that kind of attack,” Lyman said.

The alert sent out last week inadvertently identified Wolf Creek as one of the victims of the attack. An analysis of one of the tools used by the hackers had the stolen credentials of a plant employee, a senior engineer. A US official acknowledged the error was not caught until after the alert was distributed.

According to a security researcher who has seen the report, the malware that activated the engineer’s username and password was designed to be used once the hackers were already inside the plant’s computer systems.

The tool tries to connect to non-public computers, and may have been intended to identify systems related to Wolf Creek’s generation plant, a part of the facility typically more modern than the nuclear reactor control room, according to a security expert who asked to note be identified because the alert is not public.

Even if there is no indication that the hackers gained access to those control systems, the design of the malware suggests they may have at least been looking for ways to do so, the expert said.

Stan Luke, the mayor of Burlington, the largest community near Wolf Creek, which is surrounded by corn fields and cattle pastures, said he learned about a cyber threat at the plant only recently, and then only through golfing buddies.

With a population of just 2,700, Burlington boasts a community pool with three water slides and a high school football stadium that would be the envy of any junior college. Luke said those amenities lead back to the tax dollars poured into the community by Wolf Creek, Coffey County’s largest employer with some 1,000 workers, 600 of whom live in the county.

E&E News first reported on digital attacks targeting US nuclear plants, adding it was code-named Nuclear 17. A senior US official told Bloomberg that there was a bigger breach of conventional plants, which could affect multiple regions.

Industry experts and US officials say the attack is being taken seriously, in part because of recent events in Ukraine. Antova said that the Ukrainian power grid has been disrupted at least twice, first in 2015, and then in a more automated attack last year, suggesting the hackers are testing methods.

Scott Aaronson, executive director for security and business continuity at the Edison Electric Institute, an industry trade group, said utilities, grid operators and federal officials were already dissecting the attack on Ukraine’s electric sector to apply lessons in North America before the US government issued the latest warning to “energy and critical manufacturing sectors”. The current threat is unrelated to recently publicised ransomware incidents or the CrashOverride malware, Mr Aaronson said in an emailed statement.

Neither attack in Ukraine caused long-term damage. But with each escalation, the hackers may be gauging the world’s willingness to push back.

“If you think about a typical war, some of the acts that have been taken against critical infrastructure in Ukraine and even in the US, those would be considered crossing red lines,” Antova said.

Nova Scotia Energy Modernization Act proposes an independent system operator, focused energy regulation, coal phase-out by 2030, renewable integration, transmission upgrades, and competitive market access to boost consumer trust and grid reliability across the province.

Key Points

Legislation to create an independent system operator and energy regulator, enabling coal phase-out and renewable integration.

✅ Transfers grid control from Nova Scotia Power to an ISO

✅ Establishes a focused energy regulator for multi-sector oversight

✅ Accelerates coal retirement, renewables build-out, and grid upgrades

Nova Scotia is poised for a significant overhaul in how its electricity grid operates, with the electricity market headed for a reshuffle as the province vows changes, following a government announcement that will strip the current electric utility of its grid access control. This move is part of a broader initiative to help the province achieve its ambitious energy objectives, including the cessation of coal usage by 2030.

The announcement came from Tory Rushton, the Minister of Natural Resources, who highlighted the recommendations from the Clean Electricity Task Force's report to make the electricity system more accountable to Nova Scotians according to the authors. The report suggests the creation of two distinct entities: an autonomous system operator for energy system planning and an independent body for energy regulation.

Minister Rushton expressed the government's agreement with these recommendations, while the premier had earlier urged regulators to reject a 14% rate hike to protect customers, stating plans to introduce a new Energy Modernization Act in the next legislative session.

Under the proposed changes, Nova Scotia Power, a privately-owned entity, will retain its operational role but will relinquish control over the electricity grid. This responsibility will shift to an independent system operator, aiming to foster competitive practices essential for phasing out coal—currently a major source of the province’s electricity.

Additionally, the existing Utility and Review Board, which recently approved a 14% rate increase despite political opposition, will undergo rebranding to become the Nova Scotia Regulatory and Appeals Board, reflecting a broader mandate beyond energy. Its electricity-related duties will be transferred to the newly proposed Nova Scotia Energy Board, which will oversee various energy sectors including electricity, natural gas, and retail gasoline.

The task force, led by Alison Scott, a former deputy energy minister, and John MacIsaac, an ex-executive of Nalcor Energy, was established by the province in April 2023 to determine the needs of the electrical system in meeting Nova Scotia's environmental goals.

Minister Rushton praised the report for providing a clear direction towards achieving the province's 2030 environmental targets and beyond. He estimated that establishing the recommended bodies would take 18 months to two years, and noted the government cannot order the utility to cut rates under current law, promising job security for current employees of Nova Scotia Power and the Utility and Review Board throughout the transition.

The report advocates for the new system operator to improve consumer trust by distancing electricity system decisions from Nova Scotia Power's corporate interests. It also critiques the current breadth of the Utility and Review Board's mandate as overly extensive for addressing the energy transition's long-term requirements.

Nova Scotia Power's president, Peter Gregg, welcomed the recommendations, emphasizing their role in the province's shift towards renewable energy, as neighboring jurisdictions like P.E.I. explore community generation to build resilience, he highlighted the importance of a focused energy regulator and a dedicated system operator in advancing essential projects for reliable customer service.

The task force's 12 recommendations also include the requirement for Nova Scotia Power to submit an annual asset management plan for regulatory approval and to produce reports on vegetation and wood pole management. It suggests the government assess Ontario's hydro policies for potential adaptation in Nova Scotia and calls for upgrades to the transmission grid infrastructure, with projected costs detailed by Stantec.

Alison Scott remarked on the comparative expense of coal power against renewable sources like wind, suggesting that investments in the grid to support renewables would be economically beneficial in the long run.

Calistoga Resiliency Centre Microgrid delivers grid resilience via green hydrogen and BESS, providing island-mode backup during PSPS events, wildfire risk, and outages, with black-start and grid-forming capabilities for reliable community power.

Key Points

A hybrid green hydrogen and BESS facility ensuring resilient, islanded power for Calistoga during PSPS and outages.

✅ 293 MWh capacity with 8.5 MW peak for critical backup

✅ Hybrid lithium-ion BESS plus green hydrogen fuel cells

✅ Island mode with black-start and grid-forming support

Energy Vault, a prominent energy storage and technology company known for its gravity storage, recently secured US$28 million in project financing for its innovative Calistoga Resiliency Centre (CRC) in California. This funding will enable the development of a microgrid powered by a unique combination of green hydrogen and battery energy storage systems (BESS), marking a significant step forward in enhancing grid resilience in the face of natural disasters such as wildfires.

Located in California's fire-prone regions, the CRC is designed to provide critical backup power during Public Safety Power Shutoff (PSPS) events—periods when utility companies proactively cut power to prevent wildfires. These events can leave communities without electricity for extended periods, making the need for reliable, independent power sources more urgent as many utilities see benefits in energy storage today. The CRC, with a capacity of 293 MWh and a peak output of 8.5 MW, will ensure that the Calistoga community maintains power even when the grid is disconnected.

The CRC features an integrated hybrid system that combines lithium-ion batteries and green hydrogen fuel cells, even as some grid-scale projects adopt vanadium flow batteries for long-duration needs. During a PSPS event or other grid outages, the system will operate in "island mode," using hydrogen to generate electricity. This setup not only guarantees power supply but also contributes to grid stability by supporting black-start and grid-forming functions. Energy Vault's proprietary B-VAULT DC battery technology complements the hydrogen fuel cells, enhancing the overall performance and resilience of the microgrid.

One of the key aspects of the CRC project is the utilization of green hydrogen. Unlike traditional hydrogen, which is often produced using fossil fuels, green hydrogen is generated through renewable energy sources like solar or wind power, with large-scale initiatives such as British Columbia hydrogen project accelerating supply, making it a cleaner and more sustainable alternative. This aligns with California’s ambitious clean energy goals and is expected to reduce the carbon footprint of the region’s energy infrastructure.

The CRC project also sets a precedent for future hybrid microgrid deployments across California and other wildfire-prone areas, with utilities like SDG&E Emerald Storage highlighting growing adoption. Energy Vault has positioned the CRC as a model for scalable, utility-scale microgrids that can be adapted to various locations facing similar challenges. Following the success of this project, Energy Vault is expanding its portfolio with additional projects in Texas, where it anticipates securing up to US$25 million in financing.

The funding for the CRC also includes the sale of an investment tax credit (ITC), a key component of the financing structure that helps make such ambitious projects financially viable. This structure is crucial as it allows companies to leverage government incentives to offset development costs, including CEC long-duration storage funding, thus encouraging further investment in green energy infrastructure.

Despite some skepticism regarding the transportation of hydrogen rather than producing it onsite, the project has garnered strong support. California’s Public Utilities Commission (CPUC) acknowledged the potential risks of transporting green hydrogen but emphasized that it is still preferable to using more harmful fuel sources. This recognition is important as it validates Energy Vault’s approach to using hydrogen as part of a broader strategy to transition to clean, reliable energy solutions.

Energy Vault's shift from its traditional gravity-based energy storage systems to battery energy storage systems, such as BESS in New York, reflects the company's adaptation to the growing demand for versatile, efficient energy solutions. The hybrid approach of combining BESS with green hydrogen represents an innovative way to address the challenges of energy storage, especially in regions vulnerable to natural disasters and power outages.

As the CRC nears mechanical completion and aims for full commercial operations by Q2 2025, it is poised to become a critical part of California’s grid resilience strategy. The microgrid's ability to function autonomously during emergencies will provide invaluable benefits not only to Calistoga but also to other communities that may face similar grid disruptions in the future.

Energy Vault’s US$28 million financing for the Calistoga Resiliency Centre marks a significant milestone in the development of hybrid microgrids that combine the power of green hydrogen and battery energy storage. This project exemplifies the future of energy resilience, showcasing a forward-thinking approach to mitigating the impact of natural disasters and ensuring a reliable, sustainable energy future for communities at risk. With its innovative use of renewable energy sources and cutting-edge technology, the CRC sets a strong example for future energy storage projects worldwide.

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.

Ofgem UK Electricity Interconnectors will channel subsea cables, linking Europe, enabling energy import/export, integrating offshore wind via multiple-purpose interconnectors, boosting grid stability, capacity, and investment under National Grid analysis to 2030 targets.

Key Points

Subsea links between the UK and Europe that trade power, integrate offshore wind, and reinforce grid capacity.

✅ Two new subsea interconnector bids open in 2025

✅ Pilot for multiple-purpose links to offshore wind clusters

✅ National Grid to assess optimal routes, capacity, and locations

Ofgem has opened bids to build two electricity interconnectors between the UK and continental Europe as part of the broader UK grid transformation now underway.

The energy regulator said this would “bring forward billions of pounds of investment” in the subsea cables, such as the Lake Erie Connector, which can import cheaper energy when needed and export surplus power from the UK when it is available.

Developers will be invited to submit bids to build the interconnectors next year. Ofgem will additionally run a pilot scheme for ‘multiple-purpose interconnectors’, which are used to link clusters of offshore wind farms and related innovations like an offshore vessel chargepoint to an interconnector.

This forms part of the UK Government drive to more than double capacity by 2030, and to manage rising electric-vehicle demand, as discussed in EV grid impacts, in support of its target of quadrupling offshore wind capacity by the same date.

Interconnectors provide some 7 per cent of UK electricity demand. The UK so far has seven electricity interconnectors linked to Ireland, France, Belgium, the Netherlands and Norway, while projects like the Ireland-France connection illustrate broader European grid integration.

Balfour Beatty won a £90m contract for onshore civil engineering works on the Viking Link Norway interconnector, which is due to come into operation in 2023, while London Gateway's all-electric berth highlights related port electrification.

It said that interconnector developers have in the past been allowed to propose their preferred design, connection location and sea route to the connecting country. Ofgem has now said it may decide to consider only those projects that meet its requirements based on an analysis of location and capacity needs by National Grid.

Ofgem has not specified that the new interconnectors must link to any specific place or country, but may do so later, as priorities like the Cyprus electricity highway illustrate emerging directions.

Hydro-Québec Unified Corporate Structure advances the energy transition through integrated planning, strategy, infrastructure delivery, and customer operations, aligning generation, transmission, and distribution while ensuring non-discriminatory grid access and agile governance across assets and behind-the-meter technologies.

Key Points

A cross-functional model aligning strategy, planning, and operations to accelerate Quebec's low-carbon transition.

✅ Four groups: strategy, planning, infrastructure, operations.

✅ Ensures non-discriminatory transmission access compliance.

✅ No staff reductions; staged implementation from Feb 28.

As Hydro-Que9bec prepares to play a key role in the transition to a low-carbon economy, the complexity of the work to be done in the coming decade requires that it develop a global vision of its operations and assets, from the drop of water entering its turbines to the behind-the-meter technologies marketed by its subsidiary Hilo. This has prompted the company to implement a new corporate structure that will maximize cooperation and agility, including employee-led pandemic support that builds community trust, making it possible to bring about the energy transition efficiently with a view to supporting the realization of Quebecers’ collective aspirations.

Toward a single, unified Hydro

Hydro-Québec’s core mission revolves around four major functions that make up the company’s value chain, alongside policy choices like peak-rate relief during emergencies. These functions consist of:

1. Developing corporate strategies based on current and future challenges and business opportunities
2. Planning energy needs and effectively allocating financial capital, factoring in pandemic-related revenue impacts on demand and investment timing
3. Designing and building the energy system’s multiple components
4. Operating assets in an integrated fashion and providing the best customer experience by addressing customer choice and flexibility expectations across segments.

Accordingly, Hydro-Québec will henceforth comprise four groups respectively in charge of strategy and development; integrated energy needs planning; infrastructure and the energy system; and operations and customer experience, including billing accuracy concerns that can influence satisfaction. To enable the company to carry out its mission, these groups will be able to count on the support of other groups responsible for corporate functions.

Across Canada, leadership changes at other utilities highlight the need to rebuild ties with governments and investors, as seen with Hydro One's new CEO in Ontario.

“For over 20 years, Hydro-Québec has been operating in a vertical structure based on its main activities, namely power generation, transmission and distribution. This approach must now give way to one that provides a cross-functional perspective allowing us to take informed decisions in light of all our needs, as well as those of our customers and the society we have the privilege to serve,” explained Hydro-Québec’s President and Chief Executive Officer, Sophie Brochu.

In terms of gender parity, the management team continues to include several men and women, thus ensuring a diversity of viewpoints.

Hydro-Québec’s new structure complies with the regulatory requirements of the North American power markets, in particular with regard to the need to provide third parties with non-discriminatory access to the company’s transmission system. The frameworks in place ensure that certain functions remain separate and help coordinate responses to operational events such as urban distribution outages that challenge continuity of service.

These changes, which will be implemented gradually as of Monday, February 28, do not aim to achieve any staff reductions.
