In 1995, a technical consultancy committee submitted its recommendations regarding the power station designs. These recommendations in turn were passed on to the Hydro-project Institute in Russia. The Institute completed the designs, and presented them to the consultancy Company- Lahmeyer International, which signed a contract in 1999, to review the Dam Designs Documents.

    After preparation of tender documents, and their presentation in April 2002, three International Companies working in the field of manufacturing Hydro-power Generation installations, received the bidding documents.

Signing of the Power Station Contract: Presidential Palace 2003

    On the 1st of July 2003, and following many preparatory and introductory meetings, and site visits, in which the Implementation Unit and the Consultant replied to all contractors queries, three international consortiums working in manufacturing power generation equipments submitted their applications. They are:

a) a French Company (Alstom)

b) A German-Austrian Consortium

c) A two-Chinese Companies Consortium

 

    The work continued in vetting and evaluating the bid applications by the Consultant and the National Work Group representing the Project's Implementation Unit. The process, which took place in the consultant office in Germany, was completed in August 2003.

   At the end of September 2003, two companies were tentatively selected, they were: Alstom, the French Company, and the German-Austrian Consortium. After a series of explanatory technical meetings, between the Owner and the Consultant, Alstom was finally selected for the job.

   A $300 million contract was signed with Alstom to manufacture and install 10 turbine units with a capacity of  125 MW for each, to generate a total of 1250 MW. The first two turbines will start generating electricity in July 2007, and the installation for the rest of turbines will complete by August 2008.

   At the contract signing ceremony, the Minster of Electricity, Mr. Ali Tamim Fartak, stated that  the power production from Merowe Dam will make Sudan an advanced digital country.

  The most significant feature about this station is that it is situated behind the Dam, as a part and parcel of the Damís main body. This will facilitate the process of maintaining all the facilities, and reduce the total structure of the Dam. In designing the station, it has been observed that the production should not be affected by the increase in the silt, as in the case of other Dams in the country.

  

The Hydro-mechanical Equipments:

The Hydro-mechanical Equipments are part of the power station. The Unit and the Consultant agreed during the bidding stage that the Hydro-mechanical Equipment project should be separated from the rest of the station componentsí contract.
On 6th Oct. 2003, the CCMD Consortium won this contract. This is the same Consortium that previously won the Civil Works contract (the Damís main body). The winning of this company is advantageous for the Project, as it will reduce the coordination efforts between the contractors, and will better facilitate performing works related to the inbuilt parts in the concrete body.
The contract includes designing, manufacturing, and installation of equipments for the flooding gates, the lower gates, the Damtop equipments, the mechanical equipment supporting the installation of Damís body and the services
 

 

This equipment includes the main pipes, the control gates, and transmittersí cranes, and the backdoors gates and crane, the lower flooding gates, and the protective net, the maintenance gates in front of and behind the Dam, the Dam top cranes, and maintenance and services gates.

The contract value is 52.730.000 Euro, and was complete in 14th May 2008.

 China has provided 85% of funds for this contract and the Republic of Sudan secured the remaining 15%.
