Hydro power plant (5,4MW) in Kyrgyzstan

The project involves the construction of a small hydro power plant (hereinafter referred to as “SHPP”) with a capacity of 5.4 MW at a potential site located on the Talas River, Talas District, Talas Region, Kyrgyzstan. The topography of the terrain makes it possible to build the SHPP with an open-flow intake system.

The location of the SHPP was chosen given the highest slope with maximum development of the river hydroelectric potential.

The potential annual electric energy output is 36.8 million kWh.

Overview

• The location of the intake has been chosen taking into consideration the topography of the terrain.
• The open-flow intake system will be 5.6 meters long. The total pressure will be 50 meters and the average slope of the pressure intake system will be 8.9 meters per kilometer.
• The preliminary total area of land plot allocated for the construction of the main structures of the SHPP is 20.2 hectares, including water intake (6.3 ha), diversion canal (11.0 ha), power house and appurtenant structures (2.9 ha).
• The location of the SHPP was chosen given the highest slope with maximum development of the river hydroelectric potential. Access roads to the water intake on the right shore – there is a field road along the diversion canal, to the station building on the left shore.

Keypoints

• Nearby 110/35/10 kV Chat Bazaar substation. The capacity of substation is 25,000 kVA. The aerial line to connect to the Chat Bazaar substation is 7.3 km long.
• The nearby 8,000 kVA 35/10 kV Kyrk-Kazyk substation. Taking into account the potential capacity of the SHPP and the distance from the SHPP to the substation, the construction of a 35 kV aerial line and a 35 kV step-up substation is necessary.
• According to Google Maps, the length of the 35 kV aerial line connecting the Small HPP switchyard with the “Chat Bazaar” substation will be 2.7 km.
• Advantageous location of the facility. The location of the HPP was chosen taking into account the highest slope with maximum development of hydroelectric potential of the river. Access roads to the water intake on the right shore – there is a field road along the diversion canal, to the station building on the left shore.
• The topography of the terrain makes possible the construction of an HPP with an open-flow intake system, which reduces the project cost.
• High hydroelectric potential. The hydroelectric potential of the country is 142 billion kWh. The Kyrgyz Republic ranks third in the CIS in terms of the HPP and SHPP capacity.
• Low development of the potential. As of 2021, the utilization rate is 10% of the total hydroelectric potential of the country.
• High capacity of HPP cascades. According to experts, the total capacity of prospective HPP cascades is 5,600 billion kWh.
• CASA-1000. The Kyrgyz Republic is a member of the CASA-1000 project aimed at creating a power line linking Central and South Asia.

Status
