Bollingstedt, a town in northern Germany: The largest battery storage facility in Germany is located here. Project manager Carina von Schleinitz shows me the secrets of the plant. 64 mega-containers, packed with battery technology, guarantee high voltage on demand. Slow coal-fired power stations could soon become obsolete as an energy reserve.
"We are doing pioneering work," smiles the project manager proudly. "Until now, many still lived in a very conventional world in which a quarter of an hour played a significant role (in stabilising the electricity grid). But, we need to react within seconds, because volatile renewables, as the name suggests, generate volatility."
