Total Losses in Power Distribution and Transmission Lines
Technical losses are normally 22.5%, and directly depend on the network characteristics and the mode of operation. The major amount of losses in a power system is in
Technical losses are normally 22.5%, and directly depend on the network characteristics and the mode of operation. The major amount of losses in a power system is in primary and secondary distribution lines. While transmission and sub-transmission lines account for only about 30% of the total losses.
Regarding the global system energy balance, there is no specific treatment for power losses. Power losses are treated as any other induced or occurred imbalance. Since power losses are physically injected, there are no specific tariff requirements for losses.
The major amount of losses in a power system is in primary and secondary distribution lines. While transmission and sub-transmission lines account for only about 30% of the total losses. Therefore the primary and secondary distribution systems must be properly planned to ensure within limits.
Reducing power losses contributes to greater energy efficiency and security of supply and is an important goal, not least because the costs of power losses are often passed on to consumers. This report contains a set of recommendations for good practices that could be adopted so as to better benchmark and reduce technical and non-technical losses.
