How to scientifically calculate the electricity cost of energy storage systems?-Shenzhen ZH Energy Storage

Two or three years ago, when the cost of energy storage per kilowatt hour was higher than 0.5 yuan/kilowatt hour, people had no motivation to build energy storage systems for peak shaving. Because they couldn''t pay off their debts and couldn''t make ends meet, they would rather dispose of the excess electricity that was not used up.
