Assuming that the system is used for daily cycling on the power generation side, even after 15 years of use, the total cost of electricity per kilowatt hour is still as high as 0.516 yuan/kilowatt hour. It is not difficult to imagine why there is still not much power on the power generation side to actively build energy storage systems.
Another factor to consider is operating and maintenance costs. The cost of an energy storage system is not final when you purchase it—there are also the costs involved in keeping it up and running. These can be high, especially for certain batteries which require frequent maintenance.
