2 Sentenced in White Supremacy Plot to Attack National Power Grid

When most people talk about “disrupting the system,” they mean starting a new app, not trying to literally shut off the lights across America.
But in a chilling domestic terrorism case, two young men with white supremacist beliefs took that phrase dangerously literally. Federal prosecutors say they joined an extremist plot to attack the national power grid, hoping to sow chaos and advance a racist agenda.

In April 2023, 20-year-old Christopher Brenner Cook of Columbus, Ohio, and 24-year-old
Jonathan Allen Frost, who lived in Texas and Indiana, were sentenced in federal court after pleading guilty to
conspiring to provide material support to terrorists. Their crime: helping plan a coordinated assault on multiple power grid targets in the United States in furtherance of white supremacy.

Their story is a wake-up call on three fronts: how extremist ideologies can radicalize young people, how vulnerable critical infrastructure can become a high-profile target, and how law enforcement is trying to stay one step ahead of violent plots. Let’s unpack what happened, why it matters, and what broader lessons we can take from it.

Inside the White Supremacist Power Grid Plot

This case began not with a dramatic Hollywood-style chase, but with quiet planning in private chats and extremist online spaces. According to federal documents, Cook, Frost, and a third man,
Jackson Matthew Sawall of Wisconsin, shared white supremacist beliefs and were drawn to the idea of attacking the power grid as a way to destabilize the country.

Their logic followed a familiar pattern seen in far-right accelerationist circles:
if you hit critical infrastructure hard enough, you don’t just cause a blackoutyou potentially trigger civil unrest, undermine faith in government, and create an opening for a more openly racist, authoritarian system. This ideology, sometimes called
accelerationism, has shown up in several recent plots against power facilities.

The men researched past attacks on substations, studied vulnerabilities in the electrical grid, and discussed how coordinated strikes in multiple regions at once could have an outsized effect.
They weren’t just fantasizing; they were mapping out targets and steps to move from hateful talk to action.

The People Behind the Plot

Christopher Brenner Cook

Cook, the youngest of the group at 20, lived in Columbus, Ohio. Court materials describe him as deeply immersed in extremist ideology and in close communication with like-minded peers in online spaces.
He wasn’t a cartoon villain mastermind; he was a real person who slid from online hate into real-world criminal planning. That shiftfrom posting to planningis one of the biggest red flags law enforcement watches for today.

Cook ultimately pleaded guilty to conspiring to provide material support to terrorists and received a sentence of about 92 months in prison (just over 7½ years), followed by supervised release.

Jonathan Allen Frost

Frost, then 24, had lived in both Texas and Indiana. Prosecutors say he played a central organizing role, helping drive the planning, research, and ideological justification for the operation.
He and Cook weren’t just “liking” extremist content; they were trying to operationalize it by discussing specific grid targets and logistics.

Frost pled guilty to the same conspiracy charge and received a 60-month sentence (5 years) in federal prison, plus supervised release. The difference in sentences reflects both their individual roles and the timeline of their cooperation with authorities.

The Third Conspirator: Jackson Matthew Sawall

A third man, Jackson Matthew Sawall of Wisconsin, also pleaded guilty earlier in connection with the same plot and awaited separate sentencing.

Together, the three formed a small but determined cell that mirrored trends law enforcement has been warning about for years: self-radicalized individuals, linked online, moving toward “do-it-yourself” terrorism grounded in white supremacist ideology.

How the Plot Was Supposed to Work

Power grids sound abstract, but they’re physical systems: lines, transformers, substations, control centers. Take out enough of the right pieces, and you can cause outages affecting thousands or even millions of people.

According to the Justice Department, the group:

• Discussed hitting multiple substations across different regions to increase impact.
• Looked at infrastructure maps and open-source information to identify especially vulnerable nodes.
• Talked about using rifles or other weapons to damage transformers and other critical equipment, mimicking earlier unsolved attacks on electrical facilities.
• Framed the entire plan as a way to advance white supremacist goals and destabilize American society.

The idea wasn’t to make an ideological statement on social media but to engineer a real blackout and, in their own words, create unrest and fear. Investigators say the plot was explicitly tied to a vision of racially motivated violence and systemic collapse.

Fortunately, law enforcement intervened before any actual attack on energy facilities occurred. The case underscores how critically important intelligence work, informants, and monitoring of extremist spaces can be when it comes to preventing violence before it starts.

What the Court Decided – and Why It Matters

When Cook and Frost were sentenced in April 2023, federal officials didn’t mince words. The Justice Department described the case as a domestic terrorism plot “in furtherance of white supremacy,” and emphasized that attacks on critical infrastructure are treated as high-priority national security threats.

Key outcomes included:

• Cook: 92 months in prison, plus supervised release upon completion of his sentence.
• Frost: 60 months in prison, plus supervised release.
• Both: Felony convictions for conspiring to provide material support to terrorists.

Sentencing in terrorism cases is about more than just punishment. It’s also about deterrencesending a clear message that ideologically motivated attacks on infrastructure will be met with aggressive prosecution and significant prison time.
Federal authorities highlighted that young age is not a free pass when the conduct involves plotting large-scale violence.

The case also fits into a broader pattern. Over the last decade, far-right extremists and white supremacists have increasingly fixated on the power grid as a target. Reports from security researchers and government agencies show repeated attempts and plots, some involving physical attacks on substations with rifles or explosive devices.

Why White Supremacists Care About the Power Grid

On its face, the power grid might not sound like an obvious target for racist extremists. But in their worldview, it’s the perfect pressure point.

Here’s why the grid has become such a fixation:

• High impact: Knocking out electricity can disrupt hospitals, communications, businesses, schools, and basic daily life.
• Symbolic value: The grid represents modern society’s interdependence and reliance on government-regulated infrastructure.
• Psychological effect: Large-scale outages create fear, confusion, and angerexactly the emotional climate extremists hope to exploit.
• Accelerationist ideology: Some white supremacist networks openly promote the idea that “total collapse” is necessary to build a new racist order, and sabotaging infrastructure is one way they imagine getting there.

Online networks such as so-called “accelerationist” or “Terrorgram” communities amplify this focus, sharing propaganda and memes that glorify attacks on substations and other infrastructure, treating it like a dark hobby project rather than a serious crime.

Authorities have repeatedly warned that even small groupsor lone actorscan cause outsized damage with basic firearms and publicly available information about the grid. That’s exactly the kind of risk Cook, Frost, and their co-conspirator represented, and why their sentencing attracted national attention.

How This Case Connects to Other Power Grid Plots

Unfortunately, this wasn’t a one-off. In recent years, multiple cases have involved white supremacist or extremist plots against energy facilities.

For example, in Maryland, Sarah Beth Clendaniel was sentenced to 18 years in federal prison for conspiring with neo-Nazi leader Brandon Russell to attack electrical substations around Baltimore. Their plan aimed to “lay the city to waste” and cause massive disruption in a majority-Black community.

Russell, known for his role in the extremist group Atomwaffen Division, was later convicted and sentenced to 20 years in prison for his role in that Baltimore power grid plot.

Other cases, summarized by the Justice Department and terrorism researchers, show white supremacist cells experimenting with everything from firearms and explosives to online recruitment and propaganda campaigns, all with critical infrastructure in their sights.

Put together, these cases show a clear pattern: extremist movements increasingly view the power grid not just as an attractive soft target, but as a central pillar in their strategy to cause societal disruption.

What Has Been Done to Protect the Grid?

The energy sector and federal agencies haven’t been sleeping on this issue. In response to repeated threats and actual attacks, utilities and regulators have stepped up physical and cyber security across many regions.

Measures include:

• Upgraded physical barriers such as stronger fencing, walls, and access controls at substations.
• Surveillance systems with cameras, motion detection, and remote monitoring around critical sites.
• Redundancy and resilience planning so that a single damaged facility is less likely to cascade into a large-scale, long-lasting outage.
• Improved coordination between utilities, DHS, the FBI, and local law enforcement, including information-sharing on threats and suspicious activity.
• Regulatory standards from bodies like NERC (North American Electric Reliability Corporation), which set baseline requirements for protecting critical infrastructure from physical and cyber threats.

Are these measures perfect? No. No system is ever 100% safe. But the combination of better security, smarter design, and more aggressive law enforcement makes it much harder for extremist fantasies like the Cook–Frost plot to become reality.

What Ordinary People Can Take Away from This

Most of us can’t re-engineer the power grid, but cases like this still offer important lessons:

• Online extremism is not “just talk.”
  When people move from hateful memes to detailed planningespecially talking about targets, weapons, or specific infrastructurethat’s no longer just free speech; it can be a serious warning sign.
• Early intervention matters.
  Friends, family members, and online communities sometimes see worrying behavior before anyone else does. Reporting credible threats to authorities can genuinely save lives and prevent large-scale harm.
• Critical infrastructure is everyone’s business.
  We rely on electricity for nearly everything. Understanding that extremists target the grid helps communities support security upgrades, preparedness planning, and cooperative relationships with local utilities.
• Ideology plus isolation is dangerous.
  Many extremists are drawn in young, often during periods of loneliness or disconnection. Counter-extremism efforts that offer community, support, and healthier purpose are as important as police work.

In short: protecting the power grid isn’t just about transformers and high-voltage lines. It’s also about challenging the ideologies that celebrate tearing society apart.

500 Extra Words: Reflections and Real-World Experiences Around Grid Attack Plots

It’s one thing to read about a plot to attack the national power grid in a press release; it’s another to imagine what it would actually feel like on the ground. For utilities, first responders, and ordinary residents, the idea of a deliberate, ideologically driven blackout is not just scaryit’s deeply personal.

Think about a modern city on an ordinary winter evening. Lights flick on as people get home from work. Kids do homework on laptops. Someone microwaves dinner; someone else plugs in an oxygen concentrator or CPAP machine. Now imagine the power cutting out suddenly and staying outnot for an hour, but for days. Traffic lights fail, hospitals switch to backup generators, cell towers strain under emergency loads, and grocery stores toss spoiled food. That’s the human reality extremists are aiming at when they target the grid.

Emergency managers often talk about the “cascading effects” of infrastructure failures: power goes down, then communications, then water treatment, then transportation. It’s like pulling out a key Jenga piece and watching everything wobble. That’s precisely why white supremacist accelerationists obsess over substations and transmission linesthey want that wobble to turn into a collapse.

In communities that have lived through non-terrorism-related blackoutsfrom hurricanes, ice storms, wildfires, or equipment failurespeople already have a small taste of what prolonged outages can mean. Many remember waiting in gas lines, searching for ice, checking on elderly neighbors, and trying to keep medications cool. Add deliberate sabotage and a racist motive, and the emotional impact multiplies: people don’t just feel inconvenienced; they feel targeted.

For grid operators and lineworkers, these plots hit particularly hard. Their day-to-day work is basically “keep everything running smoothly so nobody notices us.” When extremists turn their facilities into symbolic targets, workers suddenly find themselves on the front line of a security challenge they didn’t sign up for. Industry professionals have described a mix of pride and anxiety: pride in hardening infrastructure and restoring power quickly; anxiety that someone might be out there viewing their workplace as the enemy.

Law enforcement and intelligence officials, meanwhile, have had to adapt to a new normal where small groups and even individuals can cause major disruptions. The Cook and Frost case is one example: relatively young men, scattered across different states, using online communication to coordinate a plan against the entire country’s electrical system. Investigators increasingly have to blend traditional toolsundercover operations, informants, and surveillancewith a nuanced understanding of online extremist subcultures and code words.

Perhaps the most important takeaway from experiences around these plots is this: prevention works, even if it’s not glamorous. Nobody throws a parade because a substation didn’t get attacked or a grid didn’t go down. But cases like this one show that quiet, behind-the-scenes interventionstips from the public, diligent monitoring of threats, timely arrests, and robust security upgradesreally do stop worst-case scenarios from becoming headlines.

For communities, the challenge is to stay realistic without becoming paranoid. Yes, extremists are interested in attacking the grid. Yes, there have been real plots, including the one that landed Cook and Frost in prison. But there are also thousands of professionals working every day to keep the lights on and a web of laws, regulations, and investigations designed to catch these schemes early. The goal isn’t to live in fear of the darkit’s to understand the threat well enough to support smart, measured responses that keep everyone safer.

In the end, the Cook–Frost case is a stark reminder that ideas have consequences. When hateful rhetoric meets detailed planning and critical infrastructure, you’re no longer dealing with abstract “views”you’re dealing with potential mass harm. The good news is that this time, the system worked: the plot was stopped, the conspirators were sentenced, and the power stayed on.
