Quality of supply and efficiency
Not long ago, the a considerable part of the transmission network could both provide quality supply in winter peaks due to the poor network, large active and reactive power losses. All this resulted in rather low voltage levels at the 110 kV level, especially in areas remote to generation sources. On the other hand, the amount of energy undelivered to consumption, as a result of restrictions in the transmission network, was rather high. Reinforcements to the network, especially after 2008, have created the conditions for a quality supply of consumption and an extraordinary reduction of power losses in the grid. The voltage level was stabilized after the commissioning of the Peja 3 project, while with further investments, the operational efficiency of the network and quality of supply were enhanced to a satisfactory level. The planned reinforcement in the next 10 years will allow for a further enhancement of quality of supply and efficiency, but also maintenance, pursuant to technical requirements of the Grid Code. The figure 6-18 shows a chart of developments in the active and reactive power losses in peak loads, based on a forecast of load for the next 10 years.
