Power Quality Emission Reduction Asset Performance

Power Factor Correction

Power factor basically is the measurement of how effectively your business uses the electricity supplied to your site. A power factor of 1 (or unity) is excellent. A power factor between 0.95 and 1 ensures your business is using its energy effectively. A power factor of below 0.95 may mean a higher than necessary kVA demand. Your business may be using energy inefficiently, resulting in unnecessary expense charged to your electricity account and reactive power charges, these came into widespread force by Electricity supply companies in April 2010.

We can tailor a power factor correction solution to the specific needs of your business.

The benefits could include:

• Better energy efficiency
• Lower costs
• Optimising the life of your electrical assets
• Reduced downtime
• Lower greenhouse gas emissions.

Our Power Factor Correction services include:

• Analysing meter data, your site conditions and the costs and benefits of solutions for both high and low voltage systems.
• Scoping, designing, supplying and installing systems.
• Unlike our competitors we don't rely on a 5 minute snapshot of your energy usages, we take time to Analyse and look at the historical trends.

Power Factor Correction systems save you save energy, money and our environment

In simple terms, power factor is a measurement of how effectively your business uses the electrical power supplied to the site.

A power factor of 1 (or unity) is excellent. A power factor of anywhere between 0.9 and 1 ensures your business is using its energy effectively. However a power factor of below 0.95 may mean a higher than necessary kVA demand. Your business may be using energy ineffectively, resulting in unnecessary expense charged on your electricity bills.

A power factor correction solution, tailored to your specific business needs, can be an effective way to improve your business’ power factor and reduce distributor demand (measured in kVA and your KW/h) ensuring you get the most from your energy.

What are the implications of a low Power Factor?

Various distribution networks in the UK, charge extra (reactive power charge) for sites with a poor power factor.

Low power factor could also lead to stressing of the internal electricity infrastructure. This may cause unnecessary overheating and equipment degeneration.

Added cost for new installations because of the need to oversize cables, switchboards and other electrical equipment.

Poor power factor can also lead to lower than “normal” voltages within a plant and consequently present unreliable equipment performance.

What benefits can be realised by addressing poor power factor?

Allows your business to lower its ongoing energy kVA demand charges, saving you money.

Allows your business to optimise the life of its electrical assets and delay or avoid unnecessary electrical system upgrade and replacement costs.

Reduces the threat of operational downtime caused by the overloading of your electrical assets within your facility.

Benefits the environment by conserving resources thus reducing greenhouse gas emissions.

Power Factor Correction Services

Power factor can be improved through the installation of automatically controlled capacitor banks or ensuring your exisiting capacitor bank is efficient. Capacitor Banks are designed and sized to suit particular site conditions and load.

Our specialist engineers can analyse your power supply at source, check your meter data, review site conditions, design and offer a turn-key power factor correction solution that is sensitive to your site’s individuality and operations.
