Voltage optimiser cuts electricity bills by 17.3%

An immediate 17.3% reduction in electricity consumption has been achieved following the installation of a voltage optimiser at Peasley Cross Hospital in St Helens. Before the installation of the equipment from Streamline Power, the average voltage on site was 246.3 V, peaking at 252.8 V —close to the legal maximum of 253 V. The voltage optimiser has reduced the voltage to 223 V, balanced the incoming phases and controlled the incoming voltage to within 0.5% of target.

The project will pay for itself in 32 months and deliver an internal rate of return of 39%.

Installation took two working days, and the electricity supply was switched over during a period of low demand in the working day.
