Studies sought for pumped-storage project in Jordan

Prequalification bids are invited by 14 July for services related to a proposed pumped-storage scheme at the Al-Mujib dam.

The German Federal Ministry for Economic Cooperation and Development (BMZ) through the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) is seeking to procure the services of a contractor to prepare a bankable feasibility study, a business model and tender documents for a pumped-storage project at the Al-Mujib dam in Jordan.

Prequalification bids are invited by 14 July.

The prospective contractor will be responsible for conducting a detailed techno-economic feasibility study, and a clear and agreed business model for the envisaged scheme, with a design capacity of 200 MW. The contractor needs to evaluate the viability of the project in technical, financial, socio-economic, institutional, and environmental terms, as well as other relevant aspects of project development based on detailed field surveys, design, cost estimate and economical and financial analysis. The contractor will carry out scoping for the environmental and social impact assessment as well as preliminary environmental and social impact assessment for the basic identification of the impacts on the biological, physical and human environments where the project is to be implemented, and recommend measures to mitigate any negative impacts. The scope of work for the contractor is structured in six work packages: inception and technical concept; field assessment studies; project alternative configurations and optimization; project design; finalize feasibility study of the selected alternative scheme; and, business model. The assignment is expected to be carried out between 1 December 2020 and 31 October 2021.

The contract is being financed by the German Federal Ministry for Economic Cooperation and Development (BMZ), which is supporting the Government of Jordan in its efforts to enhance cooperation between the country’s water and energy sectors through the Renewable Energies in the Water Sector (REW) project. This project, which is part of the German development programme ‘Management of water resources in Jordan’, is designed to improve the financial performance of the water and energy sectors and to allow for the implementation of more renewable energy projects.

A pre-feasibility study conducted in 2018 by the EU-funded project (REEE II TA) to investigate the potential of pumped storage hydropower in Jordan, and its effect on Jordan’s load balancing and grid stability, identified the Al-Mujib dam in Al-Karak governorate in southern Jordan as having good potential in terms of both technical and economic feasibility, with the lowest projected specific cost of energy storage compared with the Wadi Al-Arab and King Talal dams. The study for a pumped-storage scheme coincides with plans for a new dam close to the existing Al-Mujib dam for the purpose of increasing water storage and improving water quality in the area. In this case, the planned dam could also be used as the upper reservoir for the intended pumped-storage project. The Wadi Nukheila dam, located between 4.5 and 6 km upstream of the Al-Mujib dam with an expected storage capacity of 10 – 15 x 106 m3, is to be constructed in the next four years regardless of the pumped-storage project. The water sector is now in the process of preparing the first draft of the terms of reference for providing consultancy engineering services for investigating and designing the Wadi Nukheila dam. However, if integrating the Wadi Nukheila dam into the pumped-storage project is found to be feasible, the specific terms related to the pumped-storage project could be incorporated into the terms of reference of the Wadi Nukheila dam.
