The construction of the Surkhan-Puli-Khumri transmission line will increase the supply of electricity from Uzbekistan to Afghanistan by 70%, up to 6 billion kWh per year. The power line will connect the energy system of Afghanistan to the unified energy system of Uzbekistan and Central Asia and may become part of CASA-1000.
Its total length will be about 260 kilometers, of which 45 fall for the territory of Uzbekistan and 215 – for Afghanistan.
The total cost of the project is $ 150 million, of which $ 118 million is invested by the Afghan side, and $ 32 million by the Uzbek side. The Asian Development Bank has pledged $ 70 million for the project.
The payback period of the project is 12 years. The capacity of the new transmission line is estimated at 1,000 MW, which will allow exporting 24 million kWh per day, about 6 billion kWh per year.
