Summary

Researchers from Forschungszentrum Jülich, University of Cologne, and KIT reveal that 60-second fluctuations in the European power grid are caused by regular state-of-charge checks performed by large-scale battery storage systems. The study, published in Nature Energy, shows these checks create measurable demand spikes that can affect turbine wear, and suggests randomizing the check timing to reduce synchronized load. The work highlights how end-device monitoring and data analytics can improve grid resilience.
