On June 30, the Japan International Cooperation Agency (JICA) signed a grant agreement (G/A) with the Government of the Republic of Tajikistan in Dushanbe to provide grant aid of up to 2.19 billion yen for the Project for Improvement of Substations in Dushanbe.
The project will improve the substation facilities in Dushanbe, the capital city of Tajikistan, to stabilize the supply of power, thereby contributing to sustainable socioeconomic development.
Tajikistan depends on hydroelectricity for approximately 90 percent of the total power capacity produced domestically, but the hydroelectric power generation output drops in winter to about 70 percent of that in summer due to the freezing of riverbeds and a reduced water flow. In contrast to this drop in the power supply, the demand for power increases rapidly in winter due to the use of heaters and furnaces, resulting in many power shortages in Dushanbe particularly in winter.
Most of the power distribution facilities in the country, including substations, have not been updated since the Soviet Union period to meet the rise in the demand for power. As the equipment has deteriorated over time, it has become more difficult to find repair parts. Moreover, when the demand for power increases to the point that the load exceeds the design standard, the equipment goes into an emergency shutdown, a frequent occurrence that causes power outages. The age and inadequate number of substations are thus hindering the stable supply of power.
This project will improve existing aging substations and provide new substations in areas where the demand for power is rising rapidly, and by doing so, the project is expected to stabilize the power supply.
