I have at least find the correct forum i can post and i hope i have some responses,in partucaliry in comparison of other african dam.

Here is a little resume about this dame:

The Merowe Dam on the Nile is the largest hydropower project currently under construction in Africa. Once completed in 2008/09, the dam’s reservoir will be 200 kilometers long.

The dam will produce some 1250 megawatts of electricity and eight transmission lines with a combined length of 1760 kilometers (1100 miles) will connect it to the national grid via a station in Merowe.

The $1.5 billion Merowe Dam, designed by Lahmeyer International of Germany and built by CCMD of China, is to produce 1,250 megawatts of electricity and provide water for the irrigation of the potentially very fertile Dongola reach of the Nile valley.

The Chinese CCMD joint venture, made up of the China International Water & Electric Corporation and Sinohydro Corporation (formerly China National Water Resources and Hydropower Engineering Corp.), has beaten world-renowned construction contractors to win the bid.

Arab financial institutions, including the Abu Dhabi Fund for Development, the Saudi Fund for Development, and The Arab Fund for Economic and Social Development, are providing 700 million dollars in project financing. More than 300 million dollars is coming from The Export-Import Bank of China, which is backed by several Western commercial banks. Sudan’s government is covering the remaining 500 million dollars.

The work progress from Jan to June 2006:

The heights of the concrete dam have reached the safety level required before the 2006 flooding season, which is 264 m above sea level.

The CFRD behind the concrete dam have reached 500 m in height. In that way they reach its final stages to ensure the safety of the areas affected by the flooding in front of the reservoir through the concrete works and embankments.

The ECRD which falls on the left arm of the river has been injected with rocks and embankments. Technical operations have been done to the bases in a space of 200 m long and 36 m wide, so as to improve the soil of the bases.

The total percentage of embankments in the CFRD has reached 40.5% of the total work. The percentage of concretes in the overall work has reached 55%

The International Panel of Experts has held its meeting at the dam's site to discuss the work progress.

Arrival of the First Piece of the Turbine's Rotor
Published on 23-04-2007


Eng. Ali Abdul Rahman, the Manager of the Hydro-mechanical administration at the power plant, has announced the arrival of the first Piece the Turbines rotor to Port Sudan , recently.
There are ten 125 mega watt turbines at Merowe Dam. He explained that the manufacturing of the rotor took place in Europe, by the French Contractor- Alstom; and was assembled in Gornoble town in . The assembling process lasted for 12 months. He points that the rotor consists of 13 runners; each of the runner should be manufactured separately by pouring processes, and then subjected to lathing to determine its final shape. Then it will be assembled in two parts: the first is lower, and is called the band, and the other is the upper part, and is called the crown. After that the two parts will be welded together with the band and the crown to form the rotor of the turbine. He reveals that the rotor weights 120 tons, and is 4 meters high, and the length of the diameter is 6.5 meters.
The rotor is considered the heaviest part in the turbine, and is made out of a rust-resisting, non-corroded stainless steel. It is also coated with a substance that resists the cavitations that is caused by the flaw of water. He confirmed that all the penstocks have been erected, adding that the work is progressing normally in installing the lower parts and the parts embedded in concrete part for five turbines.
He points that the spiral case has already been erected ; and it will be followed by erecting the upper part of the pit liner and then installing the rotor.
