How Cyberattacks Can Turn Battery Farms Into Grid Blackouts

Centrii's Rafael Narezzi on Dangers of Weak Controls in Decentralized Energy Systems Michael Novinson (MichaelNovinson) • March 25, 2026

Decentralized energy systems are now essential parts of energy grids as power demands for artificial intelligence-enabled data centers skyrockets. But cybersecurity for these systems hasn't kept pace, leaving battery energy storage resources exposed as they play a growing role in grid stability, said Rafael Narezzi, CEO at Centrii.

In fact, in December 2025 in Poland, cyberattackers demonstrated how they can disrupt grid balancing rather than halt production outright. The lesson for the energy sector is that weak controls in decentralized systems can quickly go from a localized disruption to major problems affecting the entire grid, he said.

"They didn't stop the production of the energy itself. They created unbalancing problems, which can degrade the grid and then actually fall ...
