Project summary

The purpose of the project. In the project’s frame it will be made the assessment and data will be obtained on mutual supplementary wind-hydropower potentials for effective management of the water resources of the country and counteraction to the droughts. In practice, it will be created a scientific and technical base for the installation of powerful wind power systems in the regions where wind energy potential is sufficient for practical utilization.

Current status of research. Currently, Tajikistan is suffering a deep energy crisis associated primarily with a deficit of traditional energy resources (oil and gas), which adversely affects the industrial potential and the economy as a whole.

At the same time, Tajikistan has huge hydropower resources. According to preliminary estimates the potential hydropower resources is equal to 527 billion kwh/year. Preliminary calculations show that if as medium-term objectives the wind power system of 500 MW would be installed this could save annually about 1.2 cubic kilometers of water in Nurek hydropower plant.

Wind energy potential is almost never used, and regulation of water is inadequate for efficient irrigation and energy utilization. Because of the shortage of electricity in the country the dumping of water from Nurek hydropower plant for electricity generation was much greater in the winter, when other countries do not need the water for irrigation. In the result in the region the conflict of interests for irrigation and energy generation is increasing that is between the demands for water for irrigation in the summer and needs to the energy in the winter that can be solved by saving of water in the reservoirs during the summer.

Effect of the proposed project on the progress in this area. Mutual supplementary wind and hydropower project is proposed in order to ensure national energy security and facilitate the management of water resources, as well as counter drought. Report BVREA (Black and Veitch Renewable Energy Assessment) assesses the potential of country’s wind energy of 1.0 GW. This level can be achieved when the melting of glaciers by 2030 will have a major impact on reducing the level of the river, and when the total installed hydropower will reach about 10 GW. As a result of the completion this project will provide the data and the necessary scientific and technological base, allowing in the future, in practice, implement pilot commercial projects on construction and commissioning of wind power systems with a capacity of 30-100 MW and more, that will assist in filling the power balance of the country in winter, saving water in reservoirs, especially in drought years and getting work experience for the integration of electricity generated by wind and hydroelectric power in the unified energy system of the country.

Competence of the project participants in this area. The staff institutions involved in the project, scientists and specialists have sufficient qualifications and experience in the field of renewable energy. This is confirmed by the successful implementation of activities under the program of ISAR (1997, 1999, 2002), EBC/UNESCAP-SPECA - Rational and efficient use of energy and water resources in Central Asia (1993-2003), GEF IFAS - Management of water resources and environment of the Aral Sea (1993-2003), USAID - Optimizing the use of water and energy resources of Syrdarya under current conditions (1998-2001), SMSK, ADB, Strategy of development of hydropower for the Government of Tajikistan (2003-2004), EUROPEADID - the use of renewable energy in Tajikistan (2006-2007), MSDSP - the use of new renewable energy technologies (2009).

Expected results and their application. As a result, the project will assess the wind potential in the regions of Tajikistan with enough wind power potential, trained specialists in this field, justify the rational use of mutual supplementary wind and hydroelectric power for effectively management the country’s water resources and combating drought. The project will create the necessary conditions for the development of basic sectors of the economy of Tajikistan power engineering, will assist in addressing economic and social development, primarily the problem of reducing poverty and improving the ecological situation in the country.

Relevance of the project to objectives of the ISTC. The project is for peaceful purpose and consistent with national priorities of Tajikistan in the field of energy, the priorities defined by the World Millennium Summit in Johannesburg and fully meet the objectives of the ISTC.

Data on the volume of work

In the frame of the project the following work will be implemented:

  • monitoring and assessment of wind and hydropower potential in the regions of Tajikistan, where wind and hydropower system can work in mutual supplementary ways;
  • test and determination of the effectiveness in natural conditions of the demonstrative (low power: 100÷200W) of wind power plants with Darrieus and Darrieus-Savonius, which along small propeller type units will also be used as visual aids for training of future professionals in the field of wind energy;
  • development, manufacture and testing of simple and reliable probes to assess the magnitude and direction of winds at different altitudes (up to 65 meters). The installation heights of the probes will b regulated. On these probes the sensors speed and direction will be installed with digital output capabilities for data processing in a computer network;
  • a study of wind speed and direction in areas with sufficient wind energy potential;
  • conducting of trainings and conferences for specialists on wind power engineering;
  • providing the results to the international scientific community.

The workload is designed for 24 months.

The roles of foreign collaborators. As collaborators of the project the following experts have expressed a desire to work: Adam Sek and Frank Schrader. They are involved in wind and hydropower and are ready according to the letter dated Adam Sek - 24.01.2011 and Frank Schrader - 11.01.2011 to share by information with us to simulate the processes and use them in practice.

Technical approaches and methodology. Key innovations in the work the use of simple and effective probes of adjustable height will be that allows quickly and cheaply solve the problem of measuring of wind speed and its direction at various altitudes.

However, it will be tested in real conditions the demonstration (low power), Darrieus and Darrieus-Savonius wind rotors, which are considered as a relatively new technology in wind power engineering.
