More Case Studies

  • Aswan 1 Hydro Electric Power Plant was completed in 1960. It was designed for a head varying between 32-10 meters. It is equipped with nine kaplan turbines of a total output of 345 MW.
  • After more than 30 years in operation, the power plant equipment has reached a stage, where major rehabilitation become mandatory to keep them in working condition for another similar period.
  • Aswan 1 Modernization Project was instigated in August 1991.
  • The contract was signed between the Egyptian Electricity Authority and a European Consortium led by ALSTOM.
  • The contract price: DM 210,850,000 plus EGP 45,700,000.
  • The Contract covered seven 47 MW turbine-generator units, the Electrical Equipment, the Instrumentation and Control System and the Water Passage.
  • By August 1996, ALSTOM had concluded what was the biggest rehabilitation and modernization project so far in the history of Egypt's hydro electric industry.
  • Technical Data for turbine generator units:
    Power rating (MVA) 49.5
    Unit capacity (MW) 47.0
    Rated voltage (kV.) 11
    Rated Power factor 0.95
    Rated frequency (HZ) 50
    Speed (r/min) 100
    Rator weight (t) 436.5
  • As a conclusion for this project, the Aswan 1 Hydro Electric Power Plant became once again one of the most advanced facilities for power generation in Egypt, and will be supplying electricity to an energy hungry nation for a long time to come.
