Premium Power Quality contracts and labeling

By Walter Hulshorst, Erik Smeets, Hans Wolse, KEMA

This report discusses some of the power quality contracts and classification systems used by distribution companies. It shows the different contracts used around the world by some groups of customers and utilities. It also covers the role of the regulator when allowing the market to agree on premium power quality contracts.

Since the majority of customers will not be interested in power quality contracts, this report describes the possiblity of classification of power quality at the point of supply for the most important power quality aspects (interruptions, voltage dips, harmonics, voltage fluctuations). This report is part two of a series covering regulation of power quality.
