This project addressed upgrading of the transmission and distribution network to meet load growth over the period 1993 to 2003. The planning horizon was structured into 2 phases of 5 years each. The work covered network planning across multiple voltage levels, including 11 kV distribution and 66 kV, 132 kV and 220 kV transmission systems.

The review included technical studies of the existing system and planned additions or modifications in 220 kV and 66 kV substations, 66 kV to 11 kV substations, 220 kV and 66 kV transmission systems, and 11 kV and low-tension distribution systems. The load growth pattern observed over the previous 5 years was used as the basis for forecasting future load growth.

TCE's Scope

TCE carried out 11 kV network analysis, 66 kV, 132 kV and 220 kV transmission system load flow studies, and sample studies of 415 V feeders. Short circuit studies were conducted, along with a review of protection and communication systems. TCE also undertook financial analysis and assessed organisational requirements. Cost estimates were prepared for implementation across 2 phases, and final reports were prepared in the required submission format for financing review.

Impact

The work enabled a structured, phased roadmap for transmission and distribution strengthening aligned to forecast demand growth over a 10-year horizon. It supported more reliable network planning by linking multi voltage technical studies with protection, communication and implementation cost planning, improving readiness for staged execution.
