Rehabilitation of Hydro Power Plants (HPPs) on the Charyn River: Aktogay #2 HPP (1000 kW) and Aktogay #1 HPP (800 kW).


Country and location:
Republic of Kazakhstan
Location: South Kazakhstan, Toldykurgan Oblast


Type of the principal GHGs targeted for reduction by the project- CO2


Project category: - Renewable Energy
Sector of economy is in the process of privatization
The project is a renewable energy project designed to generate electricity from hydro resources for supply to local and/or national grid.

Project description:

  • Objectives:
    The principle objective of the project is to demonstrate the technical and financial viability of rehabilitating old and abandoned small and mini-hydropower stations that are in existence in Kazakhstan. A secondary objective is to promote the development of small and mini-hydropower plants on the numerous small rivers in Kazakhstan.
  • Current situation and expected outcomes:
    The Aktogay hydroelectric power plants were initially constructed in 1969. They had a total capacity of 1.8 MW with Aktogay #1 having a capacity of 800 kW and Aktogay #2 having a capacity of 1000 kW. The operation of these HPPs was stopped in 1971 for reasons that are not immediately clear. Due to neglect and non-use, the HPPs need significant rehabilitation to become operational again. It is expected that 30 percent of the cost of the project will be for rehabilitating or replacing the electro-mechanical equipment of the hydropower plant while 70 percent will be targeted at the cleaning, repair and rehabilitation of water canals and pipes associated with the project.
  • Outcomes:
    Rehabilitation of the small HPPs and connection of the two HPPs to the existing local/national grid to provide electricity for rural settlements of Taldykurgan oblast
  • Current status
    A pre-feasibility study has been completed for the project.

Total project capital costs: 1,15 mln USD

Expected environmental benefits including GHG emission reductions (tons CO2 per year or total emission reduction over the project's technical life time (t CO2) assuming project's technical life period- X years)

Annual Emission Reduction -14 689 tons of CO2
ERs for Project Life (for 20 years)- 293 788 tons of CO2


Compliance with national and local development objectives and contribution to Sustainable development
The energy sector development strategy up to the year 2030 outlines river basins and regions that are most suitable for construction of small hydroelectric plants. At present it is feasible to construct 23 small and middle-sized hydroelectric plants with 600 MW cumulative capacities. The realization of the project also assists in creation of new working places, improvement of social atmosphere and economy development. The promotion of renewable energy is within the framework of the National Environmental Action plan and Government strategy in energy sector of Kazakhstan up to 2030 and obligations under UNFCCC. The small and mini-hydropower stations are based on the "run-of-river" water resources and therefore have little or no environmental impact on water resources and water ecology.
