On February 25th, NIO Vice President Shen Fei stated on Weibo that the Danish battery swapping station has successfully started providing frequency regulation services to the power grid. This is a small step for NIO Energy in Europe and a big step for the entire battery swapping business model, marking the participation of battery swapping stations as energy storage devices in grid frequency regulation services. Shen Fei expressed his expectation that China's battery swapping stations can also enter the field of vehicle network integration and interaction for peak shaving and frequency regulation on a large scale in the form of aggregated virtual power plants.
