Conventional Hydro vs Pumped Storage
• Conventional Hydro
- Water passes
through a turbine and continues down the river
• Pumped Storage
- Cyclical system
with water passing through reversible
turbines

Growth Forecasts
• Long Term Planning – Eskom & NER have identified a need for enhanced peak generation capacity to serve:
- Growth in the industrial sector
- Successful rural electrification programme
• IPSS selected for design and development ahead of many other alternatives considered since the 1980’s
Stages of Design
• In 1998 IPSS recommended for study at feasibility level
• Study undertaken by Eskom’s own Hydro and Water Dept. and completed in November 2003
• Feasibility Report suggested an installed capacity of 1 000MW, and
• After subsequent optimisation studies the installed capacity was increased to 1 333MW
• September 2003 interested parties invited to bid to provide consulting services for Detailed Design
Record of Decision (RoD)
• Issued by the Minister of Environmental Affairs and Tourism (13 December 2002)
Record of Decision
• Key conditions of the RoD:• An environmental management plan shall be developed and its
recommendations implemented• A bypass system shall be provided to maintain the natural
seasonal flows in the water courses at the upper reservoir• No loss of the wetland due to flooding from the upper reservoir• There shall be no negative impact on the wetland downstream
of the upper reservoir• A new cliff shall be provided for the colony of Bald Ibis to roost
and nest• Any new quarries must be below the minimum water level • The Construction spoil shall be disposed of below the minimum
water level • The upper dam must blend in with its natural surroundings• A low weir shall be built downstream of the upper dam to
distribute the water across the wetland• A baseline study shall be carried out for the wetland

Fundamentals of NEC
• Fundamental principle of the NEC
• Clause 10.1: All parties shall act as stated in the contract and in a spirit of mutual trust and co-operation.
• NEC Programme
• The NEC programme is far more than a simple bar chart showing the intended order and duration of activities to be completed. It includes the resources used (labour, equipment, etc) and therefore becomes a base comparison for any compensation event when assessing the effect thereof on the Contractor’s Defined Cost.
