During the distribution of electricity to the final consumers through the electricity distribution networks, part of the electricity is converted into heat in the electricity lines and cables (Copper loss) and part of it is lost in the creation of an electromagnetic field in the network transformers (Iron Loss). In addition, part of the distributed electricity is consumed for the operation of the network equipment, mainly in distribution substations, this loss is usually not measured. Finally, quantities of electricity consumed but not measured due to malfunctions of the electricity meters, power theft or for other reasons, are also calculated in the total network losses. The term \u201ctechnical losses\u201d is traditionally used for losses that are related to the nature of electricity networks (cooper and iron losses), for the other losses, the term \u201cnon-technical losses\u201d is used.<\/p>\n

Technical losses depend on several parameters that are mainly related to the design and development of the network (line length, number of transformers, load density, distributed generation), specifications of equipment and components of the network and the network load level in relation to its capacity. Non-technical losses are largely related to power theft.<\/p>\n

Energy losses in distribution networks are an important component of the total energy costs incurred by the final consumers. According to the current market design, suppliers bear the cost of the losses and they incorporate it into the final bills of the consumers. The expected energy losses in the distribution networks are calculated using loss factors, which are calculated by the network operators and approved by RAE.<\/p>\n
