Consulting Services for: Feasibility Study

For Rehabilitation of the Baipaza Hydropower Plant

Republic of Tajikistan

Nurek Hydropower Rehabilitation Project Phase 1

OSHC “Barqi Tojik”

Consulting Services

Contract reference: TJ NHPP CS 10

At the request of the Government of Tajikistan, the World Bank has agreed to provide financing under the Nurek Hydropower Rehabilitation Project to Barqi Tojik to carry out the necessary techno-economic studies and assessments, and prepare the required outputs to facilitate the Barqi Tojik conducting rehabilitation of the Baipaza Hydropower Project.

The Baipaza Hydro Power Plant is located on the right bank of the Vakhsh River about 9 km southeast of Yovon district in Khatlon Province, Tajikistan. It is part of the cascade along the Vakhsh River and was constructed between 1979 and 1986 with an installed capacity of 600 MW. It is located 30 km downstream from the Nurek HPP (3,000 MW) and 28 km upstream of the Sangtuda I HPP (670 MW). Upstream of Nurek, the Rogun HPP (3,600 MW) is currently under construction. The hydropower plants (HPPs) along the Vakhsh river represent the predominant energy production facilities in Tajikistan. A reliable operation of the HPPs of the cascade is essential for ensuring the power supply of Tajikistan.

Given the age of the plant, there is a need to rehabilitate/replace the electromechanical and hydromechanical equipment, strengthen the various project structures, and upgrade the safety-related features of the project, including dam instrumentation.

The objective of the study is to prepare a comprehensive feasibility study to:

• Assess the technical and operational conditions of the entire Baipaza HPP including civil structures and the installed equipment, and to analyze, in a techno-economic perspective, the rehabilitation/replacement needs so as to ensure continued safe and reliable operation of the project for a further 40 years.

• Analyze the current flood discharge capacity at Baipaza and the factors that constrain this capacity so as to identify and develop, at the feasibility level, technically feasible and economically cost-effective solutions to restore its flood discharge capacity up to the design value of 5,400 m3/sec, thereby ensuring the safe operation of the cascade at this design flood.

• Assess the potential risk from the landslide and possible consequences on the operation of the Baipaza HPP so as to identify and develop, at the feasibility level, technically feasible and economically cost-effective remedial/mitigating measures to ensure continued reliable operation of the cascade despite the risks posed by the landslide.

• Investigate the nature and extent of the risks posed to the project by adverse geological features, including the existence of gypsum, and identify and develop, at feasibility level, technically feasible and economically cost-effective solutions to mitigate these risks and ensure continued safe and unconstrained operation of the project for the next 40 years.Prepare an environmental and social impact assessment study with appropriate field work to analyze in-depth environmental and social risks and impacts with appropriate and corresponding environmental and social management plan.

• The feasibility study shall therefore appropriately address dam safety issues, upgrade instrumentation, and consider rehabilitation options to at least restore the rated capacity of the plant, extend its operating life and ensure the safety of the power plant and of its O&M staff. This would cover addressing equipment issues that currently constrain production, reliability and availability, including obsolescence issues related to the equipment, and an upgrade of Baipaza operational performance with installation of state-of-the-art monitoring, control, protection and dispatch systems. An option to increase installed generating capacity without necessitating changes to the existing civil works and without an increase in the turbine design flow will also be analyzed.

For the hydropower plant, the study will aim at the following:

• restoring the generation capacity of the plant to its installed capacity or higher;

• extending the operating life of the plant by at least another 40 years;

• improving sustainable operational efficiency, reliability and availability;

• enhancing the safety of structures and equipment to acceptable levels;

• meeting the applicable requirements for environmental, health, safety, and broader social aspects of rehabilitation and operation of the power plant;

• improving working conditions by employing the latest hydropower plant technologies including modern control, protection, and monitoring systems in the plant operation cycle.
