What Challenges
   Hydropower Background

• Hydropower has been in Africa for many years
  and is a major contributor to growing national
  economies
• Plant ranges from new to 80 years old
• Differing suppliers and technologies are
  deployed
• Sometimes obsolete equipment was supplied
• Plant has not necessarily been fully
  commissioned, adequately documented or
  spares provided
• OEM support is not close at hand
   Hydropower Background
• Hydropower utilities lack transport
  infrastructure for repairs
• Cost of repairs are a major challenge
• Difficulty in raising funds timeously
• Plant downtime negatively impacts
  national economies
• Unreliable communication channels
• Limited competence base, skills and
  human resources
   Challenges
• How to enhance hydropower’s
  contribution to the national economies
• Striking a balance in a technically
  complex environment with limited
  resources
• The urgent need for building of Human
  Capacity
      Challenges

•   Technical Skills           •   Managerial Skills
     •Plant Housekeeping            •Building confidence in
     •Stores Inventories            our own abilities
     •Maintenance methods           •Mapping of business
     and work procedures /          process
     packages / instructions        •Basic Operating
     •Outage Scheduling             Procedures
     •As built drawings        •   Policy Issues
     •Configuration                 •Understanding the
     Management in                  macro environment

     Maintenance Systems -          •Environmental impacts
     Planning and scheduling        •Siltation
  Addressing the Challenges
• Training Institutions
• Technology Transfer
• African Hydro Symposium
   Conclusion
• Limited Human Capacity Building resources
  exist and are in need of formalised coordination
• Adequate funding aligned with NEPAD
  objectives will ensure enhanced Human
  Capacity Building
• The balancing of complex technical and
  financial issues could be addressed by utilising
  a body of focused relevant coordinated
  hydropower plant trained persons to cope with
  the challenges of working in the African
  environment
