Power outages in the UK have a major impact on businesses and can cause significant productivity and financial losses each time they occur. It's not just the consumer who can suffer: if the power quality of the network is bad, then loads connected to it will fail or will have a reduced lifetime, and consequently the efficiency of the electrical installation will reduce, installation running costs and carbon footprint will be high or operation may not be possible at all, as expensive and sensitive equipment can be damaged beyond repair. Furthermore, there is a risk of not meeting the legal obligation imposed. Poor power quality is wasteful, and its correction presents a number of technical, financial and environmental benefits.
