Greater Manchester Fire & Rescue Service

GMFRS takes steps to extinguish energy waste

Why it is interesting: Greater Manchester Fire and Rescue Service is saving 328,700 kWh per annum following the installation of eleven powerPerfector VPO® units. This is equivalent to £32,000 and 179,000 kg of CO2 emissions. The project was supported with funding by the NWIEP and managed along the PRINCE2 methodology to ensure a smooth programme. GMFRS is the first fire authority to pioneer voltage optimisation across its estate.


Greater Manchester Police

Dynamic VPO® provides police protection
...and a 25% ROI

Why it is interesting: Voltage profiles vary from building to building, due to a number of factors. This case study outlines the importance of voltage logging during the design and specification of any voltage optimisation project to ensure the correct solution is applied.


National Environment Research Council

The science of savings

Why it is interesting: By its very definition, an energy saving is a particularly difficult thing to measure. This case study looks at the thorough and rigorous process that powerPerfector uses to ensure the accurate reporting of the savings its technology elicits.


RAF Brize Norton

Energy savings take flight at Brize Nortonn

Why it is interesting: With an estate valued at nearly £20 billion, with some 4,000 sites including airfields, naval bases and barracks the MOD has an energy challenge that dwarfs almost all other organisations. It is estimated that £2.9 billion is spent every year on running the estate.

*The greengauge represents the aggregate savings of powerPerfector installations in the UK, Ireland, Cyprus and Denmark. Savings correct at the time of installation using either IPMVP savings analysis or reasonable estimates, where savings analysis was not possible. Actual savings may change over time for example due to energy pricing, occupancy, equipment, rates, building re-purposing and further energy efficiency measures.
