Due to insufficient amounts of coal, the production of electricity in depots at the TPP Nikola Tesla (TENT) is lower by 10% than planned, which might make it necessary to import electricity in the winter period, Danas learns.
As a result of there not being enough coal, the thermal units at TENT B will operate at a reduced capacity this winter, which will lead to voltage drops on the power lines, which might lead to malfunctions in household appliances, explains the Danas source from Elektroprivreda Srbije.
According to Danas' findings, the production of electricity in TENT is at 89.6% of the planned amount. According to the Danas source, the monthly coal production plan in TENT A has been realized only halfway (397,000 tons), whereas only 35% (196,000) of the plan has been realized in TENT B. The result might improve by no more than six to seven thousand tons a day, as the quality of the coal is low, whereas all units are currently operational.
The Danas source adds that there are two thermal units at TENT B, with total installed power of 1,300 MW.
– A significant characteristic of these units is that they are important for the power system in Serbia because they maintain the voltage in 400-kV power lines. There is no other way to maintain the 220 volts in the end-user system through subsequent transformation. This means that, if these two blocks do not have sufficient amounts of coal to operate without obstruction, the capacities are reduced, as is the so-called reactive power, which means that more remote towns, for example, those in southern Serbia, are provided with a lower voltage, getting 190 to 200 volts in the network, instead of 220, which can result in the malfunctioning of household appliances. In the winter, when the temperature drops and when the defrosting of the coal to be unloaded is to be carried out, the units will not have sufficient amounts of coal and there will not be quality amounts of voltage in the network – the Danas source explains.
