True to their name, reactive loads spend half of their time performing an "Action" - removing energy from their circuit and storing that energy in their fields (a magnetic field for the inductor and an electric field for the capacitor) – and the other half of their time performing their "Reaction" - returning that stored energy back to their circuits.

When the voltage and current go up and down at different times, reactive power is being transmitted. How much reactive power and which direction it is flowing on a transmission line depends on how different these two times are. Two extreme examples of the time relationship between voltage and current are found in inductors and capacitors.

However, it is important to note that increasing the reactive power ramp rate of the BESS could make the BESS as quick or even quicker than the shunt capacitor. The reason is that the BESS uses fast power electronics and does not rely on the slower mechanical switching time of a circuit breaker for capacitor switching.
