Learn MoreAssuming 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.
In this context, storage costs compete with the price of electricity for end consumers, and if they are less than the final electricity prices (with all fees and taxes considered but not including the fixed costs), then the costs of storage demonstrate a positive economic performance.
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. Nowadays, the cost of energy storage systems per kilowatt hour is less than 0.2 yuan/kilowatt hour. Will the construction of energy storage on the power generation side also usher in a beautiful spring?
If is within the power supply capacity of the interconnection line, the external power grid should consider charging the energy storage system while supplying electricity; When is less than zero or greater than zero and less than, this situation mainly relies on the energy storage system to maintain the balance of .
