The Asian Development Bank (ADB) has approved a $122m grant to expand and modernise Tajikistan's electricity transmission system.
The grant will aid the country in boosting energy trading with neighbouring countries to meet its winter shortages.
The work will include development of two new 220kv transmission lines totalling 140km, and rehabilitation of substations.
A real-time supervisory control and data acquisition system will replace the outdated and partially-collapsed Soviet telecommunication system, and the central control panel in the power network to improve monitoring and decision making.
The project will also support a series of reforms to restructure Barki Tojik, the state-owned national utility company, and make operational improvements across the sector to address issues such as poor planning and maintenance, low service quality and weak financial management.
ADB's grant makes up 87% of the total project cost of $141m with the Government of Tajikistan and Barki Tojik contributing the remaining $19m.
The project is expected to be completed by February 2015.
