GridEx Highlights Drone Risks to Power Grids

In the imaginary country of Beryllia, the 2026 Globe Chalice Games were readied to begin as the nation encountered a ruthless warm front. The grid, already under pressure from the circumstances, was dealt a more impact when a coordinated set of strikes consisting of vandalism, drone, and ballistic assaults by an opponent, Crimsonia, crippled the grid’s physical framework.

This situation, influenced by the upcoming 2026 World Cup and the 2028 Olympic Games in Los Angeles, was an exercise in studying how energies can protect against and mitigate, among other threats, physical attacks on power grids Called GridEx, the exercise was organized by the Power Info Sharing and Analysis Facility (E-ISAC) from 18 to 20 November, 2025 GridEx has actually been held every two years because 2011

“We understand that danger actors aim to manipulate certain conditions,” states Michael Sphere , CEO of E-ISAC, which is a program of the North American Electric Integrity Firm (NERC), concerning developing the Beryllia situation. “The Chalice Games ended up being a good example of just how we might build a circumstance around a threat star.”

Physical attacks on the grid are climbing in the U.S., and GridEx presence was up in November as utilities grapple with how to prevent and mitigate attacks. Participation in the exercise went to its highest level given that 2019, according to a record released on 2 March. Given the variety of companies existing, GridEx estimates that more than 28, 000 specific gamers took part, consisting of utility workers and federal government companions, an all-time high given that the exercise started.

Increasing Physical Hazards to Power Grids

The united state and Canadian grids encounter expanding security problems from physical dangers, including criminal damage, assault of energy employees, intrusion of residential or commercial property, and burglary of elements, like copper electrical wiring. NERC’s 2025 E-ISAC end of year report points out greater than 3, 500 physical security violations that fiscal year, about 3 percent of which interfered with electrical power. That’s up from 2, 800 occasions mentioned in the 2023 report (3 percent of those also resulted in electricity disturbances). Yet in spite of a number of recent high-profile attacks in the united state, physical attacks on the grid are taking place worldwide.

“They’re not distinctly an U.S. point,” says Danielle Russo , executive director of the Facility for Grid Safety at Safeguarding America’s Future Power , a detached organization concentrated on progressing nationwide energy safety and security Russo states that while strikes prevail in places like Ukraine , they’re not limited to wartime circumstances. “Various other nations that are not experiencing direct conflict are experiencing boosting quantities of physical assaults on their power infrastructure,” she claims. Take Germany for example: On 3 January, an arson assault by left-wing activists in Berlin created a five-day blackout affecting 45, 000 households. That comes after a suspected arson assault on 2 pylons in September 2025 left 50, 000 Berlin families without power. Some German officials cite domestic extremism and anxieties of Russian sabotage over the last few years as reasons for enhanced protection issues over critical framework.

The uptick in strikes on the U.S. grid has actually been anchored by a variety of occurrences over the last few years. In December 2025, an engineer in San Jose, California was punished to 10 years behind bars for bombing electric transformers in 2022 and 2023 A Tennessee man was detained in November 2024 for attempting to assault a Nashville substation making use of a drone armed with explosives And in 2023, a neo-Nazi leader was amongst two apprehended in a plot to strike five substations around Baltimore with weapons, component of an raising trend in white supremacist groups preparing to assault the U.S. power market.

“Given that [E-ISAC] began publishing data back in 2016, we have actually seen a huge and constant rise in the number of reported physical security events each year,” claims Michael Coe , the vice president of physical and cyber safety programs at the American Public Power Association , a profession team that collaborates with E-ISAC to intend GridEx. While not all data is publicly readily available, Coe says there’s been a “significantly” increase over the previous years in the number of reported physical assaults on the grid.

Drone Strikes: An Expanding Protection Challenge

Throughout the imaginary Globe Chalice Gamings situation, drone attacks damaged Beryllia’s substation devices, highlighting a risk that’s gotten traction as even more drones get in the airspace.

“The concern we obtain constantly is, how do you inform if it’s a criminal, or if it’s a 12 -year-old child that obtained the drone for their birthday celebration?” says Erika Willis , the program manager for the substations group at the Electric Power Research Institute (EPRI).

One approach to track and sharp utilities to prospective hazards such as drones is called sensor combination The system consists of a pan-tilt-zoom camera efficient in 360 -degree movement installed in addition to a tripod or pole with four mounted radars. The radars incorporate with the electronic camera for a twin system that can track drones even if they’re blocked from view, says Willis. For instance, if a close-by drone flies behind a tree, hidden from the electronic camera, the radars will still detect it. The innovation is presently being tested at EPRI’s laboratories in Charlotte, North Carolina and Lenox, Massachusetts

EPRI is likewise discovering how robotics and AI can boost security systems, Willis says. One approach includes incorporating AI evaluation into robotic innovation already surveilling substation borders. Using AI can enhance detection of burglaries and damage to fencing around substations, Willis states. “Instead of a human having to go with 200 pictures of a fence, you can have the AI overlays do a few of those algorithms … If the robot has actually done the evaluation of the substation 100 times, it can then relay to you that there’s an anomaly,” Willis states.

Currently, a number of utilities in the U.S. are making use of AI assimilations in their safety and monitoring procedures. That’s thanks in part to the Tel Aviv, Israel-based Prisma Photonics , a software program firm that introduced in 2017 and has given that deployed its fiber noticing innovation throughout countless miles of transmission facilities in the U.S., Canada , Europe, and Israel A file-cabinet-sized system plugs into a substation and sends out light pulses down existing fiber optic cable televisions 30 miles in each instructions. As the pulses take a trip down the wires, a tiny fraction of the light is reflected back to the substation unit. An AI design processes the results and can categorize events based upon patterns in the optical signal as an outcome of perturbations occurring around the fiber wire.

“If we determine an occasion that we do not have a category for, and we get a comments from a consumer saying, ‘oh, this was a car crash,’ then we can identify that in the design to claim this is actually what occurred,” says Tiffany Menhorn , Prisma Photonics’ vice president of The United States and Canada.

As prep work obtain underway for the 9th GridEx in 2027, Ball states involvement in the workouts alone isn’t adequate to boost grid safety and security. Instead, he wants utilities to take what they gain from the training and apply it in their own operations. “It’s the action of doing it, versus our figure of saying, ‘here’s what our development was.’ That growth must associate with the preparedness and capability of the market.”
