As you know the meaning of recorded KWH by electrical energy meters is the actual amount of produced energy by power source or the actual amount of consumed energy by loads in power system.

As you know the meaning of recorded KWH by electrical energy meters is the actual amount of produced energy by power source or the actual amount of consumed energy by loads in power system.
Well, what is your opinion about recorded KVARH in power systems? Whether is the reactive power related to actual energy? Whether is the recorded KVARH equal to actual exchanged energy between source and loads frequently? What is the meaning of reactive power or energy term?

If for the active power (correctly the energy) exists a net flow from one point of the network to another, for the reactive power there is a continuously flow back and forth (to and fro), but the net flow is zero for a complete cycle, as the amount of energy flowing in one direction for half a cycle is equal to the amount of energy flowing in the opposite direction in the next half of the cycle. The reactive power is exchanged by different parts of the network

If you suppose at starting or collapsing of system , you have consumed reactive power , in fact you have assumed network is not an ideal capacitor . Even , in this case , what has been consumed is not reactive power in reality it is active power but slightly .
