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.
Why be reactive energy to be legally established limits?
