Regional Power Transmission Interconnection Project (Tajikistan Component)

Summary

The project's scope will cover the construction of a 220 kilovolt (kV) double-circuit transmission line that will link the hydropower stations located on the Vakhsh River in Tajikistan to the border town of Sherkan Bandar; then to Kunduz, Baglan, and Pul-e-Khumri in Afghanistan.

Expected Outcome

The project will increase Tajikistan's power export- and income-generating capacity by increasing the capacity of the Southern Grid hydroelectric power plants.

Expected Outputs

The project consists of four parts: A. Transmission lines

  • Construction of a new 220-kilovolt (kV) double-circuit river crossing at the level of Karadum village over the Pianj River to the territory of Afghanistan and
  • construction of approximately 118 kilometers (km) of new double-circuit 220 kV transmission line, from the Karadum river border crossing to Sangtuda substation.
B. Substation
  • Supply and installation of high accuracy export/import metering equipment at the Sangtuda substation and
  • construction of two-line bays to connect the new 220 kV transmission line with the Sangtuda substation.
C. Generation
  • Replacement of transformer T3 at Golovnaya hydropower plant,
  • dredging of canals at the Prepadnaya and Centralnaya hydropower plants,
  • rehabilitation and upgrading of unit 3 at Golovnaya hydropower plant,
  • rehabilitation of the excitation system at Baipaza hydropower plant, and
  • optimization of the operation of the Vakhsh cascade.
D. Metering
  • Supply of bulk metering systems for other transmission substations.
