Uzbekistan’s transmission system is composed of 1,850 km of 500 kilovolt 
(kV) lines, 6,200 km of 220 kV lines, and 15,300 km of 110 kV lines (as of 
February 2017). The country’s transmission system is connected to the Kyrgyz

Republic and Tajikistan by 200 kV and 500 kV transmission lines (Enerdata 
2015). The distribution system is composed of 13,593 km of 35 kV lines,
93,983 km of 6 kV to 10 kV lines, and 105,834 km of 0.4 kV lines. The system is 
old, with an average age of 35 years (Table 2.14).

Aging power systems cause high transmission and distribution losses. Based 
on Uzbekenergo data, system losses were over 18% in 2014, with transmission 
losses at 4% and distribution losses at 14%.
10
Technical losses were mostly 
from the low-voltage transmission and distribution lines (0.4 kV to 35 kV) due 
to poor operation and maintenance of the system. Commercial losses are as 
high as 30%. Total losses of the electricity sector are estimated at 33%–35% of 
overall production.
Outdated distribution assets and manual operations have led to inaccurate 
and inefficient revenue collection. The current metering and billing system is 
inadequate, outdated, and susceptible to tampering and potential manipulation 
of charges by customers and tariff collection officers. Uzbekenergo’s revenues 
are mostly generated domestically, with regional sales from electricity export 
to Afghanistan amounting to only 5% of total revenues. Uzbekenergo’s 
revenue collection was only about 80% or less of the potential in 2014. 
Despite continued efforts to improve the metering and accounting system, 
Uzbekenergo had accumulated $1.5 billion of receivables in 2016, an increase 
from $1.0 billion in 2010. The government has created a special bureau for all 
communal services (electricity, gas, and other communal services) under the 
Prosecutor General’s office to improve collections from customers.
