Helping You Save Money and Reduce Carbon Footprint

What is Voltage Optimisation?

Voltage Optimisation is an energy saving technique that systematically reduces the supply voltage to a site in order to reduce the energy losses in equipment.

Voltage Optimiser

An effective solution?

Energy saving through Voltage Optimisation is based on the principle that the nameplate power of a device, such as 1kW for an electric fire, will be delivered at any voltage within an operating range. In the UK the range is 207V to 253V. However, above optimum voltage, any additional energy used will not necessarily improve performance. A device that has been designed to work anywhere in Europe, such as our electric fire, has an optimum operating point of 220V. Above this voltage and at the UK supply average of 242V, the fire will deliver its heat output of 1kW plus some, but the additional power dissipated will increase running costs whilst the extra heat may not be required and will shorten equipment life. The solution? Remove the difference between the existing supply voltage and the optimum design voltage, allowing the electrical device or equipment to penetrate at its most efficient level without affecting its performance.


Fit and Forget

Requires no changes to the life style or business operations.

Effortless Process

Installation is quick and simple with no changes made to the meter.

Immediate Savings

Reduce electricity bills by an average of 12% and if higher the consumption, the more you will saved on your electricity costs.

No Maintenance

Once installed, no extra care or service is needed.

Improve Efficiency

VO work with and improves the efficiency of Solar PV systems too.

Increase Durability

Extend lifespan of electrical equipment by providing more optimised voltages.

Reducing energy consumption is key to cutting bills, lowering carbon emissions and reducing exposure to fluctuating energy prices. To help you do this, U Energy supply a range of energy saving products to help you achieve your targets. Voltage Optimisation is one of the most effective ways of saving money quickly.

Most incoming UK voltages are not at the 240V we recognise, but fluctuate across a range between 216V and 253V with an average of 242V. Most electrical equipment operates most effectively at 220V.  Reducing this higher than needed incoming mains voltage saves you money; you make a power saving because you are using less electricity.

U Energy units intelligently manage voltage by monitoring the mains voltage supply and power demand of the building, adjusting output automatically. This enables the electricity supply to better match the needs of appliances and the building at all times. Thus, resulting in greater efficiency, significantly reduced wasted energy and savings on energy bills.

Every building is different so the level of savings will vary, however any building that uses electrical appliances and lighting should be considered for voltage optimisation. Checks should be made to establish the existing mains voltage supply level. Whilst the UK supply is typically around 240Volts, some properties could be lower and therefore voltage optimisation may not always be suitable.
