The Kingdom of Morocco 

Afourer Pumped Storage Hydro-Power Plant


 

Loan No.: 397 Interest Rate: 4.5 %
Beneficiary: Office National de l'Electricite' (O.N.E.) Grace Period: 5 years
Project Cost: KD 62.1 million Maturity: 22 years
Amount of Loan: KD 25.0 million Repayment: 35 semi-annual installments
Date of Loan Agreement: 13/04/2000 First Installment: 5 years following the first disbursement
Date of Effectiveness: 16/09/2000    

 

Objectives:

The project aims at satisfying a portion of the peak electric energy demand on the Moroccan grid by using stored low-cost energy generated from a hydroelectric power plant. This will be accomplished through the use of a pumped-storage system, and will preclude the need for installing several gas turbines, with a total power rating of 450 MW, to satisfy peak demand.

Description:

The project will be located in the Azilal region, around 220 km south of the capital city of Rabat. It includes the construction of upper and lower water reservoirs, connecting ducts and pipes, and two dual pumping and generating stations. During off -peak hours low cost energy will be used to pump water to the upper reservoir, and during peak hours the water head between the two reservoirs will be used to generate electricity. The project, which is expected to be completed by the beginning of 2004, consists of the following main components:

1- Electromechanical and electric works: This includes the supply and installation of the following main components:

a. Upper reversible station: which includes two vertical reversible pump/turbine units rated at 173 MW each, two generators (which could operate as motors) and power transformers.

b. Lower reversible station: which includes two vertical reversible pump/turbine units rated at 62 MW each, two generators (which could operate as motors) and power transformers.

c. Two substations: which includes 225 kV line cells, transformer cells and bus couplers.

d. Network expansion and connection to the grid: which includes overhead lines, underground cables and switch gear cells.

2- Armouring works: which includes the supply and installation of around 4,000 tons of armouring material to be used to reinforce the high-pressure pipes.

3- Civil Works: which includes supply of building materials,  the construction of water reservoirs, the substations, the pumping stations, the pipe works and the ducts.

 4- Technical services: which includes consulting services and project supervision.

5- Institutional support: which includes design, acquisition and upgrade of the existing systems, computer hardware and software, along with providing training for O.N.E. employees.

Financing:

The Arab Fund loan covers around 40% of the total project cost. It is expected that the European Investment Bank will provide a loan for around KD 24.7 million and that O.N.E. will finance the remaining costs.
