A significant portion of Europe's renewable energy production can be remotely controlled via longwave radio. While this system is intended to stabilize the grid, it can potentially also be abused to destabilize it by remotely toggling energy loads and power plants.

In this talk, we will dive into radio ripple control technology, analyze the protocols in use, and discuss whether its weaknesses could potentially be leveraged to cause a blackout, or – more positively – to create a city-wide Blinkenlights-inspired art installation.
