In order to accurately calculate power storage costs per kWh, the entire storage system, i.e. the battery and battery inverter, is taken into account. The key parameters here are the discharge depth [DOD], system efficiency [%] and energy content [rated capacity in kWh]. ??? EUR/kWh Charge time: ??? Hours
The energy storage system is a 4MW, 32MWh NaS battery consisting of 80 modules, each weighing 3 600 kg. The total cost of the battery system was USD 25 million and included USD 10 million for construction of the building to house the batteries (built by Burns & McDonnell) and the new substation at Alamito Creek.
The current cost of storing energy per kWh is $1000 / kWh. Additionally, by using the to pump water in the water tank.
As demonstrated above, the kit for a 3-kW/6-kWh storage system costs approximately $4,200–$4,600, with a total installed cost of $11,823 (DC-coupled) to $12,287 (AC-coupled). The kit for a 5-kW/20-kWh storage system costs approximately $10,400–$10,800, with a total installed cost of $21,471 (DC-coupled) to $22,041 (AC-coupled).
