Powerstar helps BIS cut energy costs and CO2 emissions

energy management systems logoEMSc (UK) Ltd, manufacturer of the Star® range of energy saving solutions, is pleased to announce it has successfully installed five of its award-winning Powerstar voltage optimisation units at the Department for Business Innovation and Skills (BIS), resulting in immediate savings in energy consumption and a substantial reduction in electricity costs and CO2 emissions.

Installed after a site survey indicated that the incoming voltage at a number of BIS buildings was high and that the power quality was poor, the Powerstar units have achieved savings of between 6.2% and 13.7% on total electricity consumption, resulting in a significant annual cost saving in excess of £30,000 for BIS. In addition, annual CO2 emissions from the buildings have been reduced by a collective 265 tonnes.

Commenting on the project Dr Alex Mardapittas, EMSc (UK) Ltd managing director and designer of Powerstar said:

“Our team’s engineering expertise and project led approach ensured that we were able to tailor the correct solution for BIS. This meant that we were not only able to optimise savings, but also address the power quality issues.”

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, generally achieves average savings of 12-15%, improves the life expectancy of electrical equipment, and enhances power quality by reducing harmonics.

Powerstar is exported worldwide to countries including Sri Lanka, the United Arab Emirates (UAE), Bahrain, Malta and South Africa.

About Powerstar


Can save an average of 12-15% (up to 26.1% savings recorded) of electricity consumption.

Is fully designed and manufactured in the UK. All Powerstar components, including even minor items such as the paint, are sourced from UK manufacturers. The Powerstar design and any associated software are designed by EMSc UK Limited.

Requires no maintenance and has a 15 year warranty.

Comes with guaranteed savings.

Will improve the life expectancy of electrical equipment.

Will improve the power quality (reduce harmonics and improve the power factor).

Has the highest efficiency and provides better savings than any other voltage optimisation system sold in the UK (on the same load and same voltage reduction).

This has been proven in independent tests by the electricity supplier RWE npower.

RWE npower commented: We did a trial with Powerstar and one other supplier. Powerstar showed a larger overall saving compared to the other supplier. In addition, it improved the power quality more. Powerstar was the better system in all aspects, including the technical design and capabilities.
