Grid Operators Just Drilled for a Blackout They Can't Fully Trust
Utilities just war-gamed a scenario where an ice storm and a cyberattack hit the grid at the same time, and the drill has lessons for anyone who depends on the lights staying on.
Snapshot
Askaprepper.com reports that the American Public Power Association, TVA, Huntsville Utilities, Electric Cities of Alabama, and federal partners including the FBI and CISA ran a tabletop exercise called MAX 2026 in Huntsville. The scenario: a severe ice storm knocks out power across Alabama and Tennessee, and as mutual-aid crews arrive, a cyberattack corrupts the outage data they rely on to restore service.
Key points
- Real players, fake storm: 64 attendees from 26 organizations, including the National Guard and Redstone Arsenal, worked through the combined ice-storm-plus-cyberattack scenario.
- Corrupted data slows everything: if crews can't trust which lines are repaired or energized, the article notes they have to verify by hand, which means outage maps and restoration times you see may simply be wrong.
- Not hypothetical: the piece cites a December 2025 incident where the UK and EU blamed Russia's FSB for a wiper-malware attack on Poland's grid that could have cut power to half a million people.
- Utilities have a plan, you should too: the industry's Cyber Mutual Assistance program sends cybersecurity help the way line crews help after storms; FEMA's guidance says households should prepare for multi-day outages with unreliable official updates.
Quick take
When the people who run the grid rehearse a worst-case combo like this, it's not paranoia, it's planning. The takeaway for your household is the same: have your own heat source, your own information (a crank radio beats a dead app), and enough food, water, and cash to ride out a mess longer and messier than usual.
