A computer-based modelling system for electric utility planning

This paper examines the development of a computer based modelling system for electricity planning within the South African Electricity Supply Commission. The system is a specialized computer based planning system, which enables the extensive analysis of a wide variety of problems to be undertaken.

This paper explains the methodology and progress of analysis through the system and describes in detail how the planners can progress from forecasting of demand and supply parameters to the proposals for a necessary expansion of generation, transmission and distribution facilities. Finally, the paper explains the analysis required to verify the proposed projects feasibility from the point of view of corporate financing.
