What Is Power Factor Correction and Why Does It Matter?

Is your business paying for energy it doesn’t even use?

Many businesses unknowingly waste energy due to poor power factor. When your equipment draws more reactive power than needed, it causes inefficiencies that increase electricity bills. While active power does the work, reactive power adds load to your supply without benefit. This results in higher consumption and potential penalties from your energy supplier, even if you’re using the same amount of actual energy.

Why does low power factor cause higher energy costs?

Low power factor increases current demand, placing unnecessary strain on your electrical system and inflating bills. If your business relies on motors, compressors, or HVAC systems, your site is likely pulling more power than it needs due to inductive loads. The outcome is a less efficient network, increased transmission losses, and reduced lifespan of your infrastructure.

What exactly is Power Factor Correction and how does it work?

Power Factor Correction uses capacitor banks or active PFC systems to offset the effects of reactive power. These systems work by supplying the reactive power locally rather than drawing it from the grid. This improves the power factor, reduces current draw, and optimises the use of active power. The result is better efficiency and immediate cost savings without affecting your operations.

Can Power Factor Correction really reduce your maintenance bills?

Yes, because lower current means less thermal stress and fewer electrical faults across your system. By reducing strain on motors and other inductive loads, Power Factor Correction helps to prevent overheating, insulation wear, and unplanned breakdowns. This can extend equipment life and reduce the frequency of reactive maintenance.

Is your site at risk of energy supplier penalties?

If your power factor is consistently low, your supplier may apply excess reactive power charges. These charges are avoidable with proper correction. Even if you’re not currently being penalised, the inefficiencies still cost your business money. Installing a Power Factor Correction unit helps you avoid penalties and improves your power quality, providing long-term protection.

How does Power Factor Correction free up electrical capacity?

By improving your power factor, your existing infrastructure can handle more load without needing upgrades. This is especially valuable if you’re planning to scale operations. Improved efficiency means your switchgear, transformers, and cabling work within safer limits, giving you room to grow without major capital expenditure.

Is Power Factor Correction only for manufacturers?

No, it benefits a wide range of industries. From food production to logistics and warehousing, any business with motors or inductive equipment can gain from correcting their power factor. For example, cold storage warehouses running 24/7 refrigeration units or commercial facilities with HVAC systems can all reduce costs and increase operational resilience with the right PFC setup.

What kind of savings should you expect after installation?

Savings vary depending on the site’s current power factor and load profile, but most businesses see returns in under 18 months. Some recover their investment in just a few months. The gains come not only from reduced energy bills, but from improved equipment reliability, reduced downtime, and fewer disruptions.
