>> do you pay too much for power?

Energy suppliers are changing how network tariffs are calculated. Large business customers with annual consumption greater than 100MWh but less than 4GWh will be impacted by the changes.

A customers usage and impact on the network will now be charged in kilovolt ampere (kVA), through measuring overall demand and the efficiency with which they use their electricity. A customer with a good power factor rating will pay less than those with a poor power factor rating.

>> what is power factor?

There are two types of power; ‘real’ and ‘reactive’.

  • Real and reactive combined is called ‘apparent’ power.
  • Power factor is the relationship between real and apparent power or kVA.
  • Sites with poor power factor will often experience higher than average energy bills due to wasted (reactive) power.

>> benefits of installing power factor correction

In addition to saving costs by avoiding penalty charges for poor power factor, there are other additional benefits of installing power factor correction. You will notice an improvement in energy efficiency with less losses, and an increased service life through lower temperature. You will also be able to free up additional capacity and increase system load capabilities from existing equipment such as transformers, switchgear and supply cables.


Summary of benefits:

  • Avoid penalty charges
  • Improve energy efficiency
  • Increase service life
  • Additional capacity
  • Increase load capability
