The news from the Parliamentary Energy Commission that during 2019 electricity losses were up to 11 percent higher, which means that the “Kostolac” thermal power plant works only by losses, said Dejan Popovic, president of the Agency Council de Energía, reopened the issue of investments to “Elektroprivreda Srbije”, but also who makes and pays those losses.
– Planning to reduce losses is a permanent objective of the distribution – said Popović, affirming that the introduction of smart meters will reduce losses to a minimum.
Zeljko Markovic, M.Sc., former EPS director, energy consultant at Diloit, stated that losses could be less if electricity theft is stopped or minimized, old meters are replaced with smart new ones, and the remote reading of electricity consumption begins. It is necessary to replace the metering infrastructure and replace the existing deteriorated network and invest in its construction and modernization.
– If we take into account the current price of electricity at which annual deliveries are contracted of around 56 euros per megawatt hour, the total value of current electricity losses is almost 200 million euros, of which about 140 million euros euros would be justified. Which shows that there is the possibility of saving about 60 million euros a year – said Markovic.
– The implementation of “smart” meters with the possibility of remote reading is a serious multi-year project worth hundreds of millions of euros, which represents a large investment, so it is not expected to be done quickly. It is also important to invest in the rehabilitation and modernization of the electrical distribution network in addition to investing in metering infrastructure, because in this way, in addition to reducing losses, the quality of the electricity supply will be greatly improved and the number of failures will increase. reduce. through the reduction of maintenance costs – emphasized our interlocutor.
According to him, losses in electricity transmission and distribution represent the sum of technical and non-technical losses. The former have a physical dimension, because when current flows through the conductors, due to their resistance, heating occurs and a certain part of the electricity that is transferred is converted into heat. Therefore, losses in electricity transmission and distribution cannot be avoided, that is, there is no transmission and distribution without technical losses, but with the correct choice of electricity transmission and distribution system, they can be reduced to a reasonable extent. .
– Non-technical losses can be ideally eliminated, because they represent energy losses due to errors in meter reading, malfunction of certain metering devices and theft of electricity – said Markovic.
The system operator has been working for years to reduce losses.
– Network losses in 2015 were around 14 percent, or in absolute terms around 4,200 gigawatt-hours, to now amount to just over 11 percent, or in absolute terms around 3,500 gigawatt-hours, which it is still far from some real values. – declared our interlocutor.
– All this costs a lot, and on the other hand, the funds are limited – concluded Markovic.
