Power Factor Correction

Transform your site’s electrical efficiency and save thousands with Power Factor Correction.

Cut Wasted Energy

Stop paying for reactive power.

Boost Efficiency

Improve power quality and reduce strain.

Future-Proof Supply

Avoid costly upgrades and overcapacity.

What is Power Factor Correction?

Power Factor Correction (PFC) improves the efficiency of your electrical supply by reducing wasted energy. Through the controlled introduction of capacitors, we correct your site’s “power factor” – the ratio between useful power and total power drawn.

If your power factor is below 0.95, you’re likely being charged for energy you’re not actually using – also known as reactive power. We can put a stop to that.

Where are the Savings Made?

Why You’re Likely Overpaying

  • You’re hit with penalties for “reactive” power you don’t use
  • You’re billed for excessive Supply Capacity (kVA)
  • You’re losing kWh through transmission inefficiencies
  • You’re overburdening your electrical infrastructure

The Benefits of Power Factor Correction

  • Remove reactive power charges entirely
  • Reduce your authorised supply capacity (ASC) costs
  • Cut down on energy losses across your system
  • Avoid costly upgrades to your electrical network
  • Lower your CO₂ emissions and accelerate your Net Zero journey
  • Extend the life of your transformers, switchgear and cabling

Tailored Solutions to Suit Every Site

We supply and install a full range of Power Factor Correction systems:

  • Automatic PFC – Smart, responsive, and fully programmable
  • De-tuned PFC – Designed for sites with harmonic distortion
  • Thyristor-Switched PFC – Real-time correction for rapidly changing loads
  • Active PFC – High-speed, precision correction for demanding environments
  • Fixed or Semi-Automatic PFC – Cost-effective options for smaller applications

Confirming before you commit

If you’re happy with the estimated savings and want to move forward, the next step is a detailed site survey. Our team will visit your premises to verify the projected savings, assess installation requirements, and confirm the final installation cost.

Works Seamlessly with Voltage Optimisation
