      What is Power Factor?

      Power Factor is an index used to measure the efficient use of electricity. This index is measured on a range of 0 to 1.0.

      For customers taking supply at 33 kV or below, the value of the power factor to be maintained is ≥ 0.85. Power factor < 0.85 will result in power factor surcharge.

      For customers taking supply at 132 kV or above, the value of the power factor to be maintained is ≥ 0.90. Power factor < 0.90 will result in power factor surcharge.

      A high Power Factor index (e.g. above 0.85 or 0.90 ) indicates an efficient level of electricity usage. On the other hand, a low Power Factor index (e.g. under 0.85 or 0.90) shows an inefficient use of electricity, indicating electricity wastage.

      Why you need to maintain a high Power Factor?

      A high Power Factor index gives the following benefits:

         
      • No additional charges in monthly electricity bill as there is no Power Factor Surcharge
      •  
      • Extends the lifespan of electrical appliances
      •  
      • Reduces electricity wastage for electrical installations at customers’ premises
      •  
      • Conserves the environment by lowering fuel usage and helps the country reduce carbon dioxide (CO2) emissions

      Customers are encouraged to consistently maintain a high Power Factor index (above 0.85 or 0.90). A Power Factor Surcharge will be imposed on Power Factor index below 0.85 or 0.90.

      Take these steps to improve Power Factor

      Please refer to the following steps to improve Power Factor:

           
      • Install equipment that can improve Power Factor, such as a Capacitor Bank
      •  
      • Avoid operating motor-based electrical appliances without load or below the load recommended by manufacturers
      •  
      • Use motor-based electrical appliances with a high Power Factor
      •  
      • Use motor-based electrical appliances that are SIRIM-certified and have energy efficient labels
