Denmark has a high voltage electricity grid, which results in an unnecessary waste of energy when equipment and machinery are used for example in offices, industry and the retail trade. Laboratory tests conducted by the Danish Technological Institute show that this energy waste can easily be minimised by using a product called powerPerfector, a voltage optimising unit installed between the switch cabinet and the distribution board. The news is reported by energy-supply.dk. PowerPerfector optimises voltage, dealing with the discrepancy between the actual supply voltage and the optimum voltage that electrical equipment needs. On average it can reduce electricity consumption by 8-10% in e.g. office buildings, supermarkets and industrial companies. The laboratory tests from the Danish Technological Institute were presented last month to energy consultancy firms, companies and municipalities.

"According to our assessment, powerPerfector can be described as a very promising product on the market for energy- and CO2- savings. We have so far only measured the effect in relation to isolated devices, and that has given some very promising results - not least in lighting where the reduction in electricity consumption was as high as 15%," says J.C. Sørensen from the division for Energy and Environment at the Danish Technological Institute.

Brøndby and Gentofte municipalities in Denmark have achieved good results using powerPerfector in schools, nursing homes, libraries and healthcare centres. Gentofte main library has achieved an 8% reduction in electricity consumption, corresponding to an energy saving of 45,000kWh/year.

The payback time for powerPerfector is 2-5 years. It has a service life of 30 years and reportedly no maintenance costs.
