In 2001, EPRI estimated that poor power quality costs the US economy between $119 and 188 B annually.

A new survey by Leonardo ENERGY now concludes very similar figures for Europe. The study is based on the results of 62 completed PQ surveys carried out in eight European countries. Its extensive results make it possible to estimate overall PQ costs in Europe, and also to analyse many different aspects of PQ like perception of PQ problems, PQ problems versus causes, affected equipment, solutions.

PQ cost to the EU economy, according to our estimates, exceeds 150 bln €, with industry very much dominating. Dips and short interruptions account for almost 60% of the overall cost in industry and more than 50% in total.
