Voltage Optimisation

Golf clubs drive home energy savings with Powerstar

As golf clubs and their members prepare for the Ryder Cup, EMSc (UK) Ltd, manufacturer of the Star® range of energy saving solutions, is pleased to announce savings results from the installation of its award-winning Powerstar voltage optimisation system at two prestigious golf and country clubs in Essex. The installations have resulted in immediate savings in energy consumption and a substantial reduction in electricity costs and CO2 emissions.

Three Rivers Golf & Country Club was keen to reduce its impact on the environment by reducing electricity consumption and carbon emissions, and a site survey carried out by EMSc indicated that voltage optimisation offered an ideal solution for delivering substantial savings without affecting operations. A Powerstar unit was installed, which has helped Three Rivers achieve savings of 6.8% on total electricity consumption – an expected annual cost saving of £3,498. In addition, the club’s CO2 emissions have been reduced by 26.1 tonnes.

Stock Brook Country Club is also set to achieve savings of 4.3% in energy consumption after the installation of a Powerstar voltage optimisation system. The club, which offers a number of facilities, was aware of its high levels of energy usage and sought a reliable solution to reduce its energy consumption and minimise its carbon footprint. It turned EMSc (UK) Ltd, due to their reputation as experts in the field of energy management, who recommended that their Powerstar system would be ideal to help achieve cuts to both its energy bills and its carbon footprint. Since the installation, Stock Brook Country Club has achieved a reduction in electricity consumption of 53,634kWh, a electricity cost savings of £3,649 per year.

Commenting on the installations Dr Alex Mardapittas, EMSc (UK) Ltd managing director and designer of Powerstar said: “Golf clubs around the country are realising that reducing energy consumption through the simple installation of a voltage optimisation system will help to cut costs, demonstrate their commitment to environmental stewardship and ensure compliance with legislation.”

He added: “Energy management is an integral part of best practice for golf course and golf club management. Clubs seeking a reliable, proven energy saving solution – one that can help reduce carbon emissions while realising significant savings on energy consumption – can be assured of professional and specialised service from the Powerstar team.”

Powerstar is a unique triple wound system with a patented design that actively reduces a considerable percentage of electrical energy consumption. The system, which is designed and manufactured in the UK is available in fixed and electronic-dynamic variations.
Powerstar systems have been successfully installed into leisure facilities throughout the country, achieving average savings of 12-15%, improving the life expectancy of electrical equipment, and enhancing power quality by reducing harmonics.
