The Hidden Cost of Low Power Factor

Many businesses are surprised by unexpected charges on their energy bills. One culprit you might not be aware of is a power factor penalty. This article explains what power factor penalties are (the hidden cost of low power factor), how they impact your business in the UK, and how Power Efficient Solutions can help you avoid them.

Understanding Power Factor Penalties

Your electricity bill reflects the real power your business uses – the energy that runs equipment and lights. However, there’s another aspect to consider: reactive power. This unseen force doesn’t directly contribute to work being done, but it’s necessary for some equipment to function. Ideally, real and reactive power are balanced. This balance is measured by power factor, a value between 0 and 1 that indicates how efficiently your business utilises electricity.

A low power factor arises when reactive power becomes unbalanced. This strains the utility company’s infrastructure as they deliver more electricity than what’s used productively. To compensate, they may impose a power factor penalty on your bill.

The Penalty Threshold in the UK

The power factor penalty threshold in the UK isn’t a one-size-fits-all situation. Energy suppliers establish their own tariff structures, which dictate how much and when a penalty kicks in. However, there’s a general trend: most companies start applying penalties when your power factor dips below 0.95. This serves as a kind of warning zone. The further your power factor falls from this point, the steeper the penalty becomes. Think of it like a sliding scale – the lower your power factor, the more significant the financial impact on your business. Understanding your specific supplier’s tariff and taking steps to improve your power factor before you reach that penalty threshold can lead to significant cost savings.

How Much is a Power Factor Penalty?

The exact cost of a power factor penalty is difficult to predict, as it depends on your supplier’s penalty structure and overall energy consumption. However, these penalties can significantly increase your electricity bill.

How Can I Avoid Power Factor Penalties?

The good news is that you can control your power factor. Here are some steps to take:

Identify Heavy Energy Users

Certain equipment, like large motors and air conditioners, are notorious for causing low power factor. Conduct an energy audit to pinpoint these areas of concern.

Implement Power Factor Correction

Power factor correction capacitors can be installed to neutralise the reactive power and this will ensure that you reduce energy consumption, saving you money and making your company more efficient.
