Q&A

An Extract from the "Electricians Guide - To the 16th Edition of the Wiring Regulations BS7671" reads, "Since the present supply voltages in the UK lie within the acceptable spread of values, supply companies are not intending to reduce their voltages in the near future. This is hardly surprising, because such action would immediately reduce the energy used by consumers (and the income of the Companies) by more than 8%.”
If the supply companies were to consider reducing the present voltage levels it would taken an enormous investment to alter the electrical infrastructure to ensure adequate supply to all users. Another practical reason for not lowering voltage is that the grid infrastructure in the UK currently supplies voltage to many rural parts of the UK at below 207V, so if they were to drop voltage supply these areas would be trying to operate at too low a voltage (180 -190V).

Across the UK and Europe, there is a phenomenon known as 'volt creep', which means that average voltages are increasing incrementally year-on-year. Electricity suppliers and grid operators are having to increase voltage in order to compensate for ever-increasing load on the grid due, attributable to continual growth in the demand for power-hungry IT equipment. This means that large numbers of users receive a supply voltage that is much higher than the optimum level, and continues to increase.  The harmonics and power factor problems associated with this growth in IT load add to the inefficiencies experienced by users as a result.

Given that the supply companies cannot step down voltages universally, local voltage optimisation is the way to realise the savings associated with lower voltages.
