A 5 kW Li-ion-based storage system would cost roughly $1.03/kWh, whereas a 100 MW Li-ion based storage system would cost just 18.8 cents/kWh. This is still roughly double the cost of current grid electricity, but efforts are underway to decrease these costs to bring energy storage technology to grid parity.
