  • 1. 115 MW SHARMAI HYDROPOWER PROJECT District Dir, NWFP Syed Tanveer Ahmed Jafri Vice President Jafri & Associates Consulting Engineers IEEP 22 nd Multi-Topic International Symposium 2007
  • 2. Benefits to Pakistan
    • Reduce D ependency on imported Fuel
    • Reduce E mission level

    • Driving Force Behind PPIB Aggressive Pursuit to get Investment in Hydel Sector
  • 3. Background
    • 2002 Power Policy initially discouraged Oil Based IPP
    • In 2003 it was widely reported that Natural Gas Reserved were dwindling
      • This led to restriction on Natural Gas Connection to New IPP
  • 4. Benefits to IPP Hydel Specific
    • Hydel projects to be implemented under Build-Own-Operate-Transfer (BOOT) basis.
    • Hydrological Risk to be borne by Power Purchaser.
    • For Hydropower projects, priority dispatch with economic load dispatch criteria.
    • Provide protection against specified political risk.
    • Provide protection against charges in taxes and duties regimes.
  • 5. Benefits to IPP Hydel Specific
    • Two-part tariff structure consisting of fixed capacity and variable energy component is recommended with the proviso that fixed capacity payment for Hydel projects would fall between 60% to 66% of the total tariff.
    • To eliminate protracted negotiation, Implementation Agreement IA, Power Purchase Agreement PPA, Water Use License WUL have been standardized
  • 6. Seven Hydropower Projects
    • In February 2005
    • PPIB Advertised Seven (7) Hydropower Projects on ICB
