“Just by making a 10% improvement in the management of energy use, UK leisure facilities could save up to £70 million each year and reduce carbon emissions by hundreds of thousands of tonnes. In a typical sports centre, energy costs are second only to labour costs, accounting for as much as 30% of total running costs – a higher figure than in most other sectors.”

Solution to energy reduction

SavaPower is a simple way for businesses to reduce their electricity bills 24/7. It uses a technique called Voltage Optimisation which reduces your voltage, thus reducing your energy consumption and carbon footprint. SavaPower has been installed since 2002 and is a well established and proven technology, especially in the UK where electricity is supplied at an average of 240 Volts.

Electrical equipment manufacturers produce products which can be used all over the world, products for Europe are designed to work across a wide voltage range, (207 Volts to 253 Volts). Many appliances operate most efficiently at around 220 Volts. When your voltage exceeds this level, energy is wasted in both heat and vibration, which costs you money and significantly reduces the life span of your electrical appliances.
