Glasgow City Council

Partnership approach pays dividends in Glasgow

Why it is interesting: Glasgow City Council’s partnership with the Property Management and Utility Services Section of City Building Group (CBG) and SSE has seen them install more powerPerfector units than any other UK local authority. This case study examines the importance of expert advice when considering energy reduction measures.



Authorities combine to drive down energy costs

Why it is interesting: The case study outlines how collaborative working and a pro-active approach has led to greater cost and carbon savings across public bodies in Greater Manchester.


London Borough of Bexley

Saving cost and carbon across Bexley

Why it is interesting: The London Borough of Bexley has installed Voltage Power Optimisation technology across much of its estate. It has begun to utilise the energy saving solution within schools and is keen for schools to implement the technology.


London Borough of Bromley

Salix funding removes financial burden in Bromley

Why it is interesting: As austerity measures within the public sector continue to be tightened, the demand for energy efficiency funding from Salix is more competitive than ever.


Southwark Council

Putting the brakes on energy costs

Why it is interesting: It is an example of how powerPerfector’s energy saving solution can benefit a range of sites. Whilst we have saved millions of pounds and thousands of tonnes of carbon for retailers, manufacturers and high profile sites like the Tower of London, some of our best savings come from sites with very simple loads. In our work for Southwark Council, we have achieved a 19.3 per cent saving on the energy bill at Peckham Town Centre Car Park.

*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.
