Starting with 01.01.2015, the new legislation (Regulatory Authority for Energy Order no. 33/2014) states that:
The inductive reactive energy is necessary for the magnetization of the motors, to make them work.
It is generated by the coils in the consumer's circuit, but it is not consumed, it circulates back and forth between the consumer and energy producer.
The electric power supplier invoices also the reactive energy to the consumer, since the circulation of the reactive energy absorbed by the consumer creates additional losses in the supplier's distribution networks.
Therefore, the reactive energy only circulates between the producer and consumer, more precisely between electric equipment which in most occasions are capacitors ( at the producer's) and coils (at the consumer's).
If this circulation of reactive energy is restricted between the consumer/producer separation limit and the receptors of the consumer's internal installation, the energy losses caused in the energy distribution network will be prevented and there will be no reactive energy to invoice.
