The Department for Business Innovation and Skills (BIS) has recently installed five of EMSc’s Powerstar voltage optimisation units in its buildings, resulting in immediate savings in energy consumption and a substantial reduction in electricity costs and CO2 emissions.

The units were 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) 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.”
