Grant
The proposed Project will increase supply of renewable energy to national and regional power systems. The Project will refurbish electric and mechanical equipment for power generation at Golovnaya Hydropower Plant (HPP) in Tajikistan. This will increase availability of year-round clean power for domestic sales and for export to Afghanistan. The Project will increase the generation capacity and operational efficiency of the power plant.
The AF will support further rehabilitation of the 240MW Golovnaya Hydropower Plant (HPP) by replacing generation unit 4, the only unit not covered under the ongoing project.
The proposed AF is aligned with the same impact as the ongoing project: Increased supply of renewable energy to national and regional power systems. The AF will also retain the same outcome as the ongoing project: Increased operational efficiency of Golovnaya HPP.
While output of the ongoing project will be retained Rehabilitated electric power generation and transmission equipment of the Golovnaya hydropower plant, it will be expanded through inclusion rehabilitation of Unit 4.
Project Rationale and Linkage to Country/Regional Strategy
The total installed capacity of the BT network is 6,492.47 MW, of which hydro power plants account for 5,774.47 MW (88.9%) and the remaining capacity is provided by three Combined Heat and Power Plants (CHP): Yavan, Dushanbe-1, and Dushanbe-2. However, the current total available HPPs capacity is only 4,200 MW out of 5,774.47 MW and is expected to increase to 5,269 MW following the rehabilitation of hydropower plants. The current capacity does not meet the increasing demand especially during the wintertime triggered by population growth, accelerated urbanization and overall domestic economic growth. Moreover, the government is enhancing power trade with neighboring countries to evacuate the electricity surplus occurring during the summer. Through an ADB-funded project, Tajikistan will be reconnected to the Central Asian Power System (CAPS), from which it was disconnected in 2009 and which will increase the countrys opportunity for surplus power evacuation. Thus, to satisfy the domestic and foreign demand, the government is continuing the rehabilitation of the main HPPs, including Golovnaya.
The proposed project will further support rehabilitation of Golovnaya HPP by replacing unit 4 in addition to already replaced units 1,2,3,5 and 6. This will increase the units installed capacity by 4MW to 49 MW. The weighted average generation efficiency of the HPP will increase from 89% to 91%. The overall plant installed capacity will increase from 270 MW to 274 MW. In addition, it will increase sustainability and lifetime of the units already rehabilitated/replaced. Moreover, it will ensure uninterrupted energy generation and available power for the grid.
Impact
Increased supply of renewable energy to national and regional power systems. |
