Ongoing processes of restructuring and regulation are taking place in the electricity sectors of all European countries. These processes are intended to bring about more transparent competition in the generation and retailing of electrical energy. In this context, the physical transmission and distribution of electricity is considered to be a natural monopoly, which should be separated from generation and retailing and which needs to be regulated. New performance based regulatory frameworks are being discussed, such as price caps or revenue caps. Tn order to avoid transmission and distribution companies reducing their costs at the expense of power quality, some type of quality regulation has to be put in place. Alongside economic regulation, the object of which is to provide strong incentives for cost reduction and efficiency, quality regulation must at least provide incentives for safeguarding minimum levels of power quality. Ideally, the regulatory framework should create an environment where transmission and distribution companies are automatically inclined to provide their customers with an optimised mix of low price and high quality. As modern societies become more and more sensitive to power quality problems, some kind of PQ regulation will become inevitable in the near future. Such regulation will not be possible without sound and transparent tools for monitoring and reporting the PQ levels. These levels are used not only for regulatory issues, but also for coordination between the manufacturers of electrical equipment, the customers and the transmission and distribution companies. This article looks at methodologies for quantifying PQ levels for a range of power quality problems.
