Consulting Services for: Preparation of Emergency Preparedness

Plan for Vakhsh Cascade

Republic of Tajikistan

Nurek Hydropower Rehabilitation Project Phase 1

OSHC “Barqi Tojik”

Consulting Services

Contract reference: TJ NHPP CS 17

At the request of the Government of Tajikistan (GoRT), the World Bank has agreed to finance preparation of an Emergency Preparedness Plan (EPP) for the Vakhsh Cascade in Tajikistan under the Nurek Hydropower Rehabilitation Project.

The electricity supply mix of Tajikistan is dominated by hydropower. The total installed generation capacity is currently 6,100 MW, and hydropower plants account for about 88 percent. The 3,000 MW Nurek HPP, with a seasonal reservoir, is the largest generating plant, although the under-construction Rogun HPP will eventually have an installed capacity of 3,600 MW. Nurek currently generates about 50 percent of the total annual energy requirements and is also the balancing plant in the system. The generation from the hydropower plants reduces significantly in winter due to reduced river flows.

The thermal power plants are primarily operated in winter to supply electricity and heat. The bulk of thermal energy-based generation comes from the new 400 MW coal-fired Dushanbe-2 combined heat and power plant (CHP), which was completed in 2017. BT also operates about 50 MW of capacity, from 200 MW, at Dushanbe-1 CHP.

The main rivers in Tajikistan are classified as transboundary, because they cross the boundaries of two countries (Vakhsh, Pyanj, Kofarnihon and Zeravshan rivers) or four countries (Amu Darya, Syr Darya). During the Soviet period, water resources were shared among the five Central Asia republics based on master plans for water resources development in the Amu Darya and Syr Darya river basins.

The six-hydropower plants along the Vakhsh River represent the predominant energy production facilities in Tajikistan. The two upstream plants comprise two of the highest dams in the World: the under-construction Rogun Dam (335 m) and the Nurek Dam (300 m) constructed in the 1970s. The two reservoirs have large storage capacities (13.3 bcm and 10.5 bcm respectively). An emergency at either of these plants that results in a sudden uncontrolled release of large volumes of water could have serious adverse consequences on downstream habitations and infrastructure, including the downstream hydropower plants. Such events could result in large-scale loss of life and serious economic and environmental impacts. The impacts could extend into the territories of the downstream riparian countries (Afghanistan and Uzbekistan).

Emergency preparedness is an essential element for ensuring both the safety of dams and that of downstream communities. The EPP specifies a predetermined plan of action that a dam owner should implement if a dam safety emergency develops. The EPP will comply with applicable Tajik regulations, the relevant requirement given in the World Bank’s Environmental and Social Framework (ESF), and the World Bank’s Operational Policy OP4.37 on Safety of Dams. Even the releases from extreme design floods at Rogun and Nurek could cause significant downstream impacts that need to be analyzed and appropriately incorporated in the EPP.

Vakhsh Cascade

The Vakhsh Cascade consist of the following one power plant under-construction – Rogun and five existing power plants: Nurek, Baipaza, Sangtuda-1, Sangtuda-2 and Sarband (also known as Golovnaya HPP), all located on the Vakhsh river, listed from upstream to downstream.

In addition, there are two power plants on the Main Vakhsh Canal: Sharshara (also known as Perepadnaya HPP) and Markazi (also known as Centralnaya HPP). This canal offtakes from the tailrace of Sarband HPP and returns to the Vakhsh river bed before its confluence with the Pyanj river.

Study Objectives and Scope of Services

The Consultant is to prepare a full-fledged Emergency Preparedness Plan for the Vakhsh Cascade in compliance with applicable legal and administrative provisions of Tajikistan and meeting the guidelines and recommendations of the World Bank. The Plan will be based on topographic data of the required accuracy, estimation of releases for different emergency and extreme design flood scenarios, and simulation of downstream inundation levels.

The EPP shall provide clear and concise guidance on emergency actions: i) how to identify an emergency (as early as possible), ii) how to classify the emergency, and iii) how to respond to the emergency.

The Consultant is to prepare and present to the Client an EPP that will provide adequate information to the Client to enable it to mitigate potential emergencies and, if an emergency occurs, to take pre-determined appropriate and timely action to mitigate the impacts of the emergency.

The work to be carried out within this study is divided into several Tasks, each with specific activities and deliverables

Task 1: Information Gathering and Inception Report

Task 2: Risk Assessment

Task 3: Methodology, Scenarios and Assumptions

Task 4: Emergency Preparedness Plan

Task 5: Note for Downstream Riparian Countries
