Mystery solved: Coordinated power drops have been haunting power grid worldwide, but a team of researchers in Germany found the culprit.
Coordinated disturbances haunt grids worldwide. Here’s how researchers solved the mystery.

Key takeaways
Researchers identified global electrical frequency drops caused by hydropower turbine resonance, posing risks to grid stability.
- Mysterious frequency drops occurred every 60 seconds on global power grids.
- Resonance from hydropower turbines was found to cause ultra-low frequency oscillations.
- Such oscillations can damage equipment and lead to blackouts if not managed.
