Voltage Optimisation is a way of controlling voltage levels to within European Harmonised voltage limits to return an energy saving. It is a proven technology that deals with the comparatively high voltage levels used within the UK compared to the rest of Europe.
In the UK the average voltage supplied by the National Grid is 242 volts whereas in the rest of Europe this average is 220 volts. This higher voltage within the UK leads to higher bills and increased wear and tear on equipment that is designed to run at lower levels of voltage.
Simply put voltage optimisation reduces the levels of voltage to your equipment thereby reducing the energy used and extending the life-span of the equipment.
The equipment used to enable voltage optimisation is designed to save energy whilst addressing the problems of over-voltage and poor power quality. The results that are seen are savings through reduced energy consumption of typically between 5% & 15% and the enhanced life-span of electrical equipment.
The levels of savings typically achieved will enable a payback on investment of between 1 and 3 years.
Examples of savings achieved through voltage optimisation include –
- A chain of 5 convenience stores achieved annual savings of 10.2% with a payback of 2.1 years
- A 78-bed care home achieved annual savings of 14.25% with a payback of 1.2 years
- A petrol forecourt operator achieved annual savings of 20.15% with a payback of 2 years
Voltage Optimisation provides a great opportunity for savings in energy consumption and for the reduction in CO2 emissions.
