Voltage optimisation technology has been listed by Siemens as one of the top 10 energy saving solutions.

In the UK and in many countries across Europe, National Grids supply most buildings and facilities with an average electrical supply of 242V. Powerstar technology works by reducing this supply, whilst remaining within the operating conditions specified by equipment manufacturers, typically between 220V and 230V.

The report by Siemens highlights that if the voltage supplied to a building is too high it may also reduce efficiency and lead to equipment failure alongside increased maintenance.

It also states that, depending on the equipment being powered, lowering supply voltage to electrical equipment can save between 5 per cent and 15 per cent in energy consumption, offering payback to customers in as little as two to five years.

Powerstar is the chosen supplier of voltage optimisation technology to Siemens, with the two company’s working together to provide businesses with optimum energy saving solutions.

Dr. Alex Mardapittas, managing director at Powerstar said, “The report by Siemens reaffirms that voltage optimisation systems can continue to save energy for most businesses, no matter how small or large.”
