NHS: Rotherham General Hospital
Powerstar were engaged to replace a large hospital’s existing Uninterruptible Power Supply (UPS) system with a more efficient, intelligent Battery Energy Storage (BESS) alternative.
Case Studies
Wienerberger Ltd
Powerstar was commissioned to replace the site’s ageing transformer with modern, low-loss replacements, that incorporated voltage optimisation technology to provide more stable voltages across the site.
PFF Group
Powerstar identified PFF Group’s aging transformers as a a potential power resilience risk, as well as an area where their energy efficiency could be significantly bolstered.
AESSEAL® (UK)
AESSEAL needed help protecting their operations from power disruptions while driving forward net zero strategies.
MI Dickson
Consumption of this site has decreased by over 8,000 kWh after the Voltage Optimisation installation, despite production volume being increased by almost 10%
Lowe House Health Care Resource Centre
Voltage optimisation reduced electricity costs by £4,296 at this Health Centre and reduced CO2 emissions by 22.6 tonnes per year

“Powerstar identified waste that we did not think we had. They diligently overcame issues during commissioning and have provided us with a fault free system that saves what they promised.”
Mark Boxall, Managing Director at Tetra Pak CPS Ltd
“We would highly recommend Powerstar Voltage Regulation systems. The Powerstar installation at Scott Clinic, Mersey Care NHS Trust has achieved an 18% saving on total electricity consumption. This is an excellent result which is helping the hospital to meet its CO2 reduction targets. Powerstar Voltage Regulation has shown that significant savings can be achieved without compromising the operations of the hospital.”
Mark O’Grady, Managing Director at MITIE Engineering (North) Ltd
“We are absolutely delighted with the Powerstar system which has reduced our direct electricity and carbon emissions by 16%. I have no hesitation to recommend Powerstar to others.”
Stephen Ward, Senior Electrical and Mechanical Engineer at Sheffield Hallam University
“We have experienced no issues or problems with the Powerstar equipment we have had fitted for the past year. The kit is robustly manufactured and electrically sound.”
Peter Gardiner, M&E Manager at Lincolnshire Co-operative
“With the ability to power our site for up to two hours the Battery Energy Storage System should cover us for all but the most severe and long-term power outages, thereby maintaining the operation of our critical kilns and protecting our products and production schedules. Given the damaging impact that interruptions to our power supply have caused for such a long time, and the added benefit of reducing our energy consumption and providing an additional revenue stream, the solution provided by Powerstar was a no-brainer for our business.”
