Within the fictional nation of Beryllia, the 2026 World Chalice Video games have been set to start because the nation confronted an unrelenting warmth wave. The grid, already beneath pressure from the circumstances, was dealt an additional blow when a coordinated set of assaults together with vandalism, drone, and ballistic assaults by an adversary, Crimsonia, crippled the grid’s bodily infrastructure.
This situation, impressed by the upcoming 2026 World Cup and the 2028 Olympic Games in Los Angeles, was an train in finding out how utilities can stop and mitigate, amongst different risks, bodily assaults on power grids. Referred to as GridEx, the train was hosted by the Electricity Information Sharing and Analysis Center (E-ISAC) from 18 to twenty November, 2025. GridEx has been held each two years since 2011.
“We all know that menace actors look to use sure circumstances,” says Michael Ball, CEO of E-ISAC, which is a program of the North American Electric Reliability Corporation (NERC), about designing the Beryllia situation. “The Chalice Video games grew to become a superb instance of how we might construct a situation round a menace actor.”
Bodily assaults on the grid are rising within the U.S., and GridEx attendance was up in November as utilities grapple with methods to stop and mitigate assaults. Participation within the train was at its highest stage since 2019, in accordance with a report launched on 2 March. Given the variety of organizations current, GridEx estimates that greater than 28,000 particular person gamers participated, together with utility staff and authorities companions, an all-time excessive because the train started.
Rising Bodily Threats to Energy Grids
The U.S. and Canadian grids face rising safety points from bodily threats, together with vandalism, assault of utility staff, intrusion of property, and theft of elements, like copper wiring. NERC’s 2025 E-ISAC finish of yr report cites greater than 3,500 bodily security breaches that calendar yr, about 3 % of which disrupted electrical energy. That’s up from 2,800 occasions cited within the 2023 report (3 % of these additionally resulted in electrical energy disruptions). But regardless of a variety of current high-profile assaults within the U.S., bodily assaults on the grid are taking place worldwide.
“They’re not uniquely a U.S. factor,” says Danielle Russo, govt director of the Middle for Grid Security at Securing America’s Future Energy, a nonpartisan group targeted on advancing nationwide energy security. Russo says that whereas attacks are common in locations like Ukraine, they’re not restricted to wartime situations. “Different nations that aren’t experiencing direct battle are experiencing growing quantities of bodily assaults on their vitality infrastructure,” she says. Take Germany for instance: On 3 January, an arson attack by left-wing activists in Berlin brought on a five-day blackout impacting 45,000 households. That comes after a suspected arson attack on two pylons in September 2025 left 50,000 Berlin households with out energy. Some German officers cite home extremism and fears of Russian sabotage in recent times as causes for heightened security concerns over important infrastructure.
The uptick in assaults on the U.S. grid has been anchored by a variety of incidents in recent times. In December 2025, an engineer in San Jose, California was sentenced to 10 years in jail for bombing electric transformers in 2022 and 2023. A Tennessee man was arrested in November 2024 for attempting to attack a Nashville substation utilizing a drone armed with explosives. And in 2023, a neo-Nazi chief was amongst two arrested in a plot to attack five substations around Baltimore with firearms, a part of an increasing trend in white supremacist teams planning to assault the U.S. vitality sector.
“Since [E-ISAC] began publishing information again in 2016, we’ve seen a big and constant improve within the variety of reported bodily safety incidents per yr,” says Michael Coe, the vice chairman of bodily and cyber safety packages on the American Public Power Association, a commerce group that works with E-ISAC to plan GridEx. Whereas not all information is publicly obtainable, Coe says there’s been a “tenfold” improve over the previous decade within the variety of reported bodily assaults on the grid.
Drone Assaults: A Rising Safety Problem
In the course of the fictional World Chalice Video games situation, drone assaults destroyed Beryllia’s substation tools, highlighting a menace that’s gained traction as extra drones enter the airspace.
“The query we get on a regular basis is, how do you inform if it’s a nasty actor, or if it’s a 12-year-old child that bought the drone for his or her birthday?” says Erika Willis, this system supervisor for the substations workforce on the Electric Power Research Institute (EPRI).
One technique to trace and alert utilities to potential threats corresponding to drones is known as sensor fusion. The system features a pan-tilt-zoom digicam able to 360-degree movement mounted on high of a tripod or pole with 4 put in radars. The radars mix with the digicam for a twin system that may monitor drones even when they’re obstructed from view, says Willis. As an illustration, if a close-by drone flies behind a tree, hidden from the digicam, the radars will nonetheless decide up on it. The expertise is at the moment being examined at EPRI’s labs in Charlotte, North Carolina and Lenox, Massachusetts.
EPRI can be exploring how robotics and AI can enhance safety techniques, Willis says. One strategy includes integrating AI evaluation into robotic expertise already surveilling substation perimeters. Utilizing AI can enhance detection of break-ins and harm to fencing round substations, Willis says. “Versus a human having to undergo 200 photographs of a fence, you’ll be able to have the AI overlays do a few of these algorithms…If the robotic has executed the inspection of the substation 100 occasions, it might then relay to you that there’s an anomaly,” Willis says.
Prisma Photonics deploys fiber sensing expertise that makes use of mirrored optical indicators to detect perturbations from autos and different sources close to underground fiber cable.Prisma Photonics
Already, a variety of utilities within the U.S. are utilizing AI integrations of their safety and monitoring processes. That’s thanks partly to the Tel Aviv, Israel-based Prisma Photonics, a software program firm that launched in 2017 and has since deployed its fiber sensing expertise throughout 1000’s of miles of transmission infrastructure within the U.S., Canada, Europe, and Israel. A file-cabinet-sized unit plugs right into a substation and sends gentle pulses down present fiber optic cables 30 miles in every route. Because the pulses journey down the cables, a tiny fraction of the sunshine is mirrored again to the substation unit. An AI mannequin processes the outcomes and may classify occasions based mostly on patterns within the optical sign on account of perturbations taking place across the fiber cable.
“If we establish an occasion that we don’t have a classification for, and we get a suggestions from a buyer saying, ‘oh, this was a automotive crash,’ then we will classify that within the mannequin to say that is truly what occurred,” says Tiffany Menhorn, Prisma Photonics’ vice chairman of North America.
As preparations get underway for the ninth GridEx in 2027, Ball says participation within the workouts alone isn’t sufficient to bolster grid safety. As an alternative, he desires utilities to take what they be taught from the coaching and apply it in their very own operations. “It’s the motion of doing it, versus our statistic of claiming, ‘right here’s what our progress was.’ That progress ought to relate to the readiness and functionality of the trade.”
I modified the tense on this as a result of the following sentences use previous tense. It appeared bizarre to modify from current tense within the first sentence to previous tense in the remainder of the paragraph, however I may very well be mistaken.
