Overview

Reduce Your Auckland Business Power Costs with Power Factor Correction

Power factor is a measure of how efficiently your electrical system uses the power it draws from the grid. A poor power factor means your business is drawing more current than necessary for the useful work being done, and in New Zealand, Vector and other lines companies charge for this inefficiency through reactive power (kVAR) charges on commercial and industrial tariffs.

For Auckland manufacturers, food processors, engineering workshops and large commercial premises, power factor correction (PFC) is one of the most cost-effective investments available. A properly designed and installed PFC system can reduce electricity costs by 10 to 25% and reduce the risk of power quality-related equipment failures.

Electromech's industrial electricians conduct a thorough power quality analysis of your premises before recommending any PFC solution. We design and install the correct capacitor bank size for your load profile, avoiding the problems of over-correction, and provide ongoing monitoring to verify savings.

Common Questions

Frequently Asked Questions

What is power factor and why does it matter for my Auckland business?
Power factor is the ratio of useful (real) power to total (apparent) power consumed. A power factor of 1.0 is ideal. Most industrial premises with electric motors, compressors or HVAC equipment have a power factor of 0.7 to 0.85. Vector and other Auckland lines companies charge commercial and industrial customers for reactive power (kVAR) when power factor falls below a threshold, typically 0.90 or 0.95. Improving your power factor eliminates or reduces these charges.
How much can power factor correction save my Auckland business?
Savings depend on your current power factor, the reactive power charges in your electricity tariff, and the size of your electrical load. Auckland industrial premises with poor power factor typically achieve savings of 10 to 25% on their network charges. Electromech provides a detailed financial analysis with every PFC proposal, including estimated annual savings and payback period.
Do I need power factor correction if I have VSD (variable speed drives)?
Variable speed drives actually improve power factor on the motor circuits they control, which is beneficial. However, VSDs are non-linear loads that generate harmonics, which can cause problems with standard PFC capacitors. Where VSDs are present, we include harmonic analysis and may recommend detuned capacitor banks with series reactors to prevent harmonic resonance issues.
How long does a power factor correction installation take?
The measurement phase typically runs for 7 to 14 days using a power logger. Once the system is designed and approved, installation of a standard capacitor bank typically takes 4 to 8 hours and can be scheduled to minimise production disruption. We can often complete installation over a scheduled maintenance shutdown.
Does power factor correction require a licensed electrician in NZ?
Yes. Power factor correction equipment operates at mains voltage and connects directly to your switchboard. All installation work must be performed by a Licensed Registered Electrician in New Zealand and a Certificate of Compliance must be issued on completion.
