GridEx Highlights Drone Dangers to Energy Grids

Within the fictional nation of Beryllia, the 2026 World Chalice Video games had been set to start because the nation confronted an unrelenting warmth wave. The grid, already beneath pressure from the circumstances, was dealt an extra 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 state of affairs, impressed by the upcoming 2026 World Cup and the 2028 Olympic Video games in Los Angeles, was an train in learning how utilities can forestall and mitigate, amongst different risks, bodily assaults on energy grids. Known as GridEx, the train was hosted by the Electrical energy Data Sharing and Evaluation Heart (E-ISAC) from 18 to twenty November, 2025. GridEx has been held each two years since 2011.

“We all know that risk actors look to take advantage of sure circumstances,” says Michael Ball, CEO of E-ISAC, which is a program of the North American Electrical Reliability Company (NERC), about designing the Beryllia state of affairs. “The Chalice Video games grew to become a superb instance of how we may construct a state of affairs round a risk actor.”

Bodily assaults on the grid are rising within the U.S., and GridEx attendance was up in November as utilities grapple with tips on how to forestall and mitigate assaults. Participation within the train was at its highest degree since 2019, in keeping 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 safety 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 quite a lot of latest 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, government director of the Heart for Grid Safety at Securing America’s Future Vitality, a nonpartisan group targeted on advancing nationwide power safety. Russo says that whereas assaults are widespread in locations like Ukraine, they’re not restricted to wartime eventualities. “Different international locations that aren’t experiencing direct battle are experiencing rising quantities of bodily assaults on their power infrastructure,” she says. Take Germany for instance: On 3 January, an arson assault by left-wing activists in Berlin induced a five-day blackout impacting 45,000 households. That comes after a suspected arson assault 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 safety considerations over important infrastructure.

The uptick in assaults on the U.S. grid has been anchored by quite a lot of incidents in recent times. In December 2025, an engineer in San Jose, California was sentenced to 10 years in jail for bombing electrical transformers in 2022 and 2023. A Tennessee man was arrested in November 2024 for making an attempt to assault a Nashville substation utilizing a drone armed with explosives. And in 2023, a neo-Nazi chief was amongst two arrested in a plot to assault 5 substations round Baltimore with firearms, a part of an rising development in white supremacist teams planning to assault the U.S. power sector.

“Since [E-ISAC] began publishing information again in 2016, we’ve seen a big and constant enhance within the variety of reported bodily safety incidents per yr,” says Michael Coe, the vice chairman of bodily and cyber safety applications on the American Public Energy Affiliation, 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” enhance over the previous decade within the variety of reported bodily assaults on the grid.

Drone Assaults: A Rising Safety Problem

Throughout the fictional World Chalice Video games state of affairs, drone assaults destroyed Beryllia’s substation tools, highlighting a risk 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 received the drone for his or her birthday?” says Erika Willis, this system supervisor for the substations group on the Electrical Energy Analysis Institute (EPRI).

One technique to trace and alert utilities to potential threats reminiscent of drones known as sensor fusion. The system features a pan-tilt-zoom digital camera able to 360-degree movement mounted on prime of a tripod or pole with 4 put in radars. The radars mix with the digital camera for a twin system that may monitor drones even when they’re obstructed from view, says Willis. For example, if a close-by drone flies behind a tree, hidden from the digital camera, the radars will nonetheless choose up on it. The expertise is at present 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 method entails integrating AI evaluation into robotic expertise already surveilling substation perimeters. Utilizing AI can enhance detection of break-ins and injury to fencing round substations, Willis says. “Versus a human having to undergo 200 photographs of a fence, you may have the AI overlays do a few of these algorithms…If the robotic has completed the inspection of the substation 100 instances, it may 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 automobiles and different sources close to underground fiber cable.Prisma Photonics

Already, quite a lot 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 current fiber optic cables 30 miles in every course. 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 might classify occasions primarily based on patterns within the optical sign because 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 really 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 study 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 development was.’ That development ought to relate to the readiness and functionality of the trade.”
