POWER QUALITY -- THE ADDED VALUE The problem of Power Quality (PQ) cost in industrial customers is particularly important at present in the new scenery of competitive electricity markets. In fact, it represent the added value that the electric suppliers can provide to the users for improving their productivity and the reliability of their industrial process. The industry must compare the cost of the PQ services provided by the utilities with the cost derived from damages to the production output and/or to the plants. While this later is easy to define because is related to the physical replacement of some equipment, the cost of production losses is not simple to monetize.

Electricity supply has nowadays become a part of every day life and is a service expected by electricity consumers. Their expectations rely on the availability of electricity whenever needed and on a safe and satisfactory operation of all connected electrical devices. In order to carry out economic regulation of network charge, the Energy Agency of the Republic of Slovenia (Slovenian regulator) monitors quality electricity supply, which is divided into: reliability (continuity) of supply, voltage quality and commercial quality. The Agency monitors the parameters of quality electricity supply with the intention of permanently increasing and maintaining its level, respectively.

The Council of European Energy Regulators (CEER) has divided quality of electricity supply to: • commercial quality, dealing with service between the supplier or system operator and the consumer, • continuity (reliability) of supply, dealing with the number and duration of interruptions spotted with consumers, • quality of voltage which contains the technical characteristics of voltage measured in the receiving-transmitting point of the consumer.

Agency’s main task is to prepare and issue the methodology for the calculation of network charge and methodology for setting out the criteria for defining eligible costs while taking into consideration the mechanisms of promotion, manifested in the field of investment, ascertaining technical losses of the system and maintenance. Together with these mechanisms which monitor cost efficiency of system operators, quality of electricity supply in case of consumers also needs to be monitored. A decrease of costs in a company can be most easily reached by means of decreasing costs in the field of maintenance and investment, which can also lead to a lower quality level.

Legal bases for quality of electricity supply • The Energy Act (Official Gazette of the Republic of Slovenia No.: 26/05; EZ-UPB1) • The Decree on the method for implementing public service obligation relating to the activity of distribution system operator • The Decree on the method for implementing public service obligation relating to the activity of transmission system operator UM FERI laboratorij za energetiko jože voršič črpalne hidroelektrarne
