Case Studies

Castlefields Health Centre






Castlefields Health Centre is based in Runcorn, Cheshire and is part of the NHS Halton Clinical Commissioning Group which is made up of representatives from each of the 17 practices across Runcorn and Widnes. The organisation works with patients and healthcare professionals, as well as in
partnership with the local communities and Halton Borough Council to make sure that health and social care is linked together for people whenever possible.


The Centre was the first practice to be built in Runcorn new town, opening in May 2012 and like the Widnes Health Care Centre (part of the NHS Halton CCG), was looking for quick but effective methods to reduce CO2 emitted from energy use to ensure they meet NHS national aim of reducing carbon emissions by 34% by 2020.


Powerstar Voltage Optimisation is a proven patented method for energy and carbon reduction across a range of NHS sites across the UK helping to save thousands of pounds and help make each site greener. Along with installations at Lowe House in St. Helens and Castlefield Health Centre, Renova Developments are tasked to develop primary care estates strategy for various sites and Powerstar was installed as part of this to help deliver a consistent improvement in quality and save on carbon emissions.


The unique Powerstar system, the only voltage optimisation system with a patented design has no moving parts meaning no maintenance is required. Saved Castlefields Health Centre 13.9% on their energy bills, savings of £3,162 per year and reduced their CO2 Emissions by 29,282 kWh
