What is it? | Why is it necessary? | How is this achieved?
 

Because reducing apparent power (kV·A) and energy (kW·h, kvar·h) required from the electrical system allows:

  Helping to keep the system and environment sustainable by reducing CO2 emissions by reducing energy generation requirements.
  Improving the technical management of installations by increasing their performance (increased available capacity) and avoiding process downtime and breakdowns (controlling leakage and eliminating disturbances).
  As a result reducing the financial costs of the operation for installations and processes.
