Voltage optimisation is the control of the level of voltage of your electricity supply.
Optimising voltage can significantly reduce electrical energy use and improve the useful life of your electrical equipment. This is achieved by stabilising your voltage to 220 volts, which is the UK voltage that most electrical equipment is designed to operate at.
Interestingly, voltage feeds that are either too high or too low can cause increased use of electricity and shorten the life of your electrical equipment, without giving any improvement in performance. This is similar to a petrol engine where the same occurs if petrol injection is too much or too little.
Reducing energy consumption is key to cutting energy bills. Voltage optimisation should therefore be considered to reduce electric bills.
