NIO Vice President Shen Fei: The battery swapping station in Denmark has started to provide frequency regulation services to the grid. NIO Vice President Shen Fei stated in a Weibo post that the battery swapping station in Denmark has successfully begun to provide frequency regulation services to the grid. This is a small step for NIO Energy in Europe, and a big step for the entire battery swapping business model, signaling the participation of battery swapping stations as energy storage devices in grid frequency regulation services. Shen Fei expressed the hope that China's battery swapping stations can also enter the field of grid integration and interaction on a large scale in the form of aggregated virtual power plants for peak shaving and frequency regulation.
