Voltage optimisation is a technology where the voltage on your premises is reduced to an optimum level of 220 volts. This is the level your electrical equipment is designed to work at. This 'subtraction' produces a reduction in energy consumption, saving on electricity bills and reducing wear and tear on appliances. It also reduces the carbon emissions for the site.
70% of the UK is over-voltage and the average incoming supply is 242 volts and rising!
As electrical equipment is designed to work at 220 volts in both domestic and commercial situations, why pay for energy that you simply don’t need?
We can supply and install a voltage optimisation unit in your home or business which will provide substantial savings on your energy running costs and works for you 24/7.

FAQs about voltage optimisation
What is voltage optimisation?
Voltage optimisation is a technology where over-voltage is reduced to an optimum level that electrical equipment was designed to work at, namely 220volts. This reduces wastage and saves on energy costs.
What is the typical supply voltage in the UK?
This varies considerably; however over 70% of the UK is over-voltage with an average of 242 volts
What is the average savings by voltage reduction?
Each individual site will have unique characteristics and a variety of plant and equipment, however, we have found 10% is being saved on average and in our experience savings of up to 14% can be achieved.
What types of load are better suited for energy savings by voltage reduction?
Most loads benefit from voltage reduction as the un-reduced voltage is higher than the optimum design voltage of the equipment. As an example inductive loads and fluorescent lighting generally show high savings.
Is it feasible to use voltage optimisers in any industry?
Voltage reduction equipment could be beneficial for any industry sector. We measure suitability based on types of loads and other site specifics.
Can voltage optimisers be used in domestic applications?
Yes, our units are designed for use in domestic, commercial and industrial applications.
If I upgrade plant and machinery at my site, do I need to upgrade my voltage optimiser?
Advice should be sought if you increase your electrical consumption at your site. We will always try to allow for future site expansion. We will offer you different sized equipment to meet each specific requirement; consideration will be given if future expansion is foreseen.
Will the installation of a voltage optimiser have any negative effect on any of my electrical equipment?
No. In fact operation of electrical equipment with a reduced and regulated voltage will generally increase service life of the equipment.
What is the voltage range equipment can accept?
All electrical equipment sold in the EC needs to be capable of working with a supply voltage anywhere between 207 and 253V (230V ± 10%).
What are the benefits of a voltage optimiser to the environment?
Benefits include reduction in carbon footprint as well as a reduction in equipment replacement and maintenance requirements.
Does the equipment qualify for Enhanced Capital Allowance?
No. There are currently only 15 product ranges available through ECA and voltage optimisation / voltage regulation is not one of them. This is due to its transformer based technology. However, we can help with finance and full funding if there is no capital expenditure available.
Do we need to have a site survey and three phase logging to establish possible savings and carbon reduction?
In some cases, yes, although it does depend on the load of the site. In order to accurately establish site suitability and energy saving potential a site survey and electrical logging may be required.What happens if voltage optimiser units are overloaded?
Just like any electrical appliance, the capacity of the equipment should not be exceeded and thermal and current protection is included as part of the unit.
What is the lifetime of your product?
As with any product, the lifetime depends upon its use and treatment over time; however, its life should exceed over 25 years.
Does the voltage optimiser replace the site transformer?
No. they are complementary products to your existing LV transformer.
Does Fusion of Power provide installation?
Does Fusion of Power provide finance?
Yes, we provide lease asset purchase and we also have full funding available.
How long does installation take?
Each site has specific requirements and so each individual installation should be looked at separately. Smaller 3 phase systems should only take a few hours. Changeover time can be less than one hour.
Will out of hours’ works be possible for installation and/or switchover period?
Yes. Our engineers and installers are used to working in accordance with customers’ requirements.
Do I need to contact my energy supplier to switch off the supply during works?
Normally no contact would be required by the customer and where required we will normally deal with the District Network Operator(DNO) arrangements directly.
Will my site be without power whilst works are completed?
Fusion of Power will work together with our customers, and we will limit downtime to the shortest time possible. Where necessary use of backup power can be sought so your site has minimal interruption of service to normal activities.
Can the units be used in outdoor applications?
Yes. Standard units have IP21 rating and they are designed for indoor use. However, we have the technical knowledge to accommodate any outdoor application request to IP66.
What is the standard warranty on voltage optimisers?
Our VO units come with an extended 5 year manufacturer warranty.
What is the optimum output voltage setting?
All equipment is set at around 220V output and is dependent on existing site voltage.
It is a known factor that not all loads benefit from voltage reduction / optimisation. Could you please identify suitable loads for energy saving by voltage reduction?
Although it is true to say that not all loads offer energy saving from voltage reduction, most loads will benefit from being fed with a reduced voltage as their designed voltage is probably at or closer with a reduced voltage than it is with the unregulated mains grid supply.
Loads which generally offer significant energy savings include refrigeration, chillers, freezers, motors (excluding VSD), lighting (most types except those with high frequency ballast), some temperature controlled equipment, pumps, although there is no definitive list.
What is the efficiency of the unit?
>98% at full load
Does the equipment have metering capabilities?
This is not fitted as standard but they are available as an option.
Does the voltage optimiser improve power factor?
In some cases, yes, however designated power factor correction units should be sought if solving dedicated specific power factor issues.
Does the equipment have wheels?
Will you carry out any test after installation to identify actual savings?
We are happy to visit sites after the installation to measure energy savings.
