Why be reactive energy to be legally established limits?

The price of reactive power is regulated and is equal to the price approved for a power factor average realized in the range of settlement less than power factor neutral (power factor limit to which electricity consumption reactive not significantly influence losses and voltage regulation / reactive power into the grid, with a value of 0.92 for the regime established experimental inductive and capacitive mode 1) and greater than or equal to 0.65. For a power factor in the range of average realized settlement less than 0.65 is charged three times the regulated price approved by the competent authority.
