​
What are the consequences of a high voltage for my building?
A high voltage has a negative impact on two levels: first, the electricity bill will be higher and second, the lamps and electrical engines in the building will heat more, which may reduce their lifespan by half.
​
How does a voltage controller work?
The voltage fluctuates at the mains – typically in Europe, between 207 and 253 volts, according to the EN 50160 norm. Although it does not affect the functionality of the electric loads – designed to work within this range – it affects the electricity consumption. Stabilizing and reducing the electrical voltage directly saves energy and increases the lifetime of electrical devices and equipments.
Will I still have enough power in my building with a voltage stabilizer?
Yes, you will not notice the difference and all your electrical lamps and devices will work normally with a lower voltage set at 212-215 volts.
​
I already have LED lamps, will I still have any savings with a voltage controller?
Yes, of course! LED lamps have a lower electricity consumption than older bulbs, but you will still get 4-8% direct savings depending of the type of LED lamp. However, the savings might even be more interesting on the lamp's lifespan, as LED lamps are rather costly. With an input voltage set around 212-215 volts, you may avoid unnecessary heating of your LED lamps, thus increasing their lifespan and reducing the need of air conditiong in the building.
​
How will I also lower the building's carbon footprint?
With a voltage controller, the carbon dioxide emissions will be lowered thanks to the direct and indirect savings. In Switzerland, with every kWh used, about 125g of carbon dioxide are produced. If you double the lifespan of all your electrical appliances, you will save all the carbon dioxide linked to the manufacturing, distribution and transport of the appliances that you will not have to discard and replace.
​
How much will I save with a voltage controller?
By lowering the voltage at 212-215 volts, your peak power use will be lower and your electrical devices will be more efficient : this is the direct average saving of 10% on electricity. With a lower voltage in your building, all your electrical appliances will be protected against voltage peaks and will also heat less, which can double their lifespan. This means that you may save 50% on your budget for repair, maintenance and depreciation of your electrical appliances.
What will be my return on investment?
The return on investment depends on your direct and indirect savings potential, but also on your total electricity price (energy, network and taxes). The more you pay, the more electricity you use and the more appliances you have in the building, the shorter will be the payback period. Typically, the return on investment of an optimal voltage controller range from 3 to 5 years.
​
How does the rental model work?
If you don't have a budget to buy a voltage controller, it is also possible to opt for the rental model. In this case, once the direct and indirect savings have been calculated, an offer is made to the client to share the savings. For example, if a building has a savings potential of CHF 2'000.- per month, the client will pay a rental of CHF 1'000.- per month and keep the difference. Usually, rental contracts are signed for a period of 5 years.
