1.2 Key Information

3. The Project objective is to ensure the power exchange of Tajikistan with Uzbekistan and the reconnection of Tajikistan with the Central Asian Power System (CAPS). The Project pro-vides for the complete restoration and reconnection of the Tajik power system with Uzbek power system. This means the restoration of parallel operation of the Tajik energy system with the regional one, from which Tajikistan has been cut off in 2009. Within the Project framework in order to synchronize the electrical networks of Tajikistan and Uzbekistan, it is planned to install modern relays, circuit breakers, instrument transformers, auxiliary, and other equipment that will increase system reliability and will be installed at the connection points on 220 kV and 500 kV transmission lines.

4. In the north of Tajikistan, it is planned to install two new points of connection of Tajik network to Uzbek power system that will increase the stability of the parallel operation of the two power systems. This Project allows Tajikistan to export summer surplus electricity to Uz-bekistan, and ensure more efficient use of regional power resources.
