NHS Sustainable Development Unit research shows that voltage optimisation is the Number One electrical energy efficiency measure Acute Trusts can take to reduce energy use and cut carbon emissions.
“This equipment has helped the Trust reduce its electricity spend and carbon footprint.”

The Link Centre is a large leisure complex, comprising of an international-sized ice skating rink, swimming pool, indoor courts, climbing walls, a fitness studio and the local library.
Voltage optimisation was installed as one of a number of energy efficiency measures across the site. Average voltage onsite was 241.2V and peaked at 246.4V. It was decided to use a voltage regulator to reduce the voltage to 221V.
The Brighton and Sussex University Hospitals (BSUH) NHS Trust is the regional teaching hospital for Brighton and parts of Sussex. As part of its carbon reduction strategy, it was decided to test the effectiveness of voltage optimisation as an energy conservation measure at the Audrey Emerton Building at The Royal Sussex County Hospital. The building is not a prime site for voltage optimisation as it was only commissioned in 2005 and contains modern, energy-efficient equipment.
Health Hydro is a leisure and sports centre comprising of two swimming pools, gym, spa, Turkish baths and a natural health clinic. The site operates 7 days a week for 51 weeks per year. The site’s electricity consumption is erratic, normally running anywhere between 30kVA and a maximum of approximately 100kVA. The overnight base load was approximately 40kVA. On site voltages were high, peaking at 248V (P-N). The site is fed by a single supply directly from the street. The Council recently implemented two inverter drives for two 11kVA motors
The family owned Springfield Hotel and Leisure club offers 67 luxury bedrooms attached to leisure and spa club with indoor and outdoor heated swimming pools, hot tub, sauna, steam room, gym, squash and tennis courts, and of course a beauty treatment centre.
