  1. Technical Performance Management & Improvement Plans for Gauteng (Eskom Central Region) Presentation to Portfolio Committee on Minerals & Energy on 16 September 2005 Presenters: Peter Craig & Naresh Hari

  2. Background • In Central Region over R650 million has been invested in the last 3 years for strengthening and refurbishment. • Planned investment for the next 2 years is R350 million on further strengthening and refurbishment. • A large proportion of our investment has been made in Soweto, Sandton and Fourways areas. • The main focus in Central Region over the next two years will be in the Vereeniging, Sandton and Randfontein areas.

  3. Performance Improvement (Distribution Level)

  4. Performance Improvement (Reticulation Level)

  5. Holistic Contributions to Reliability Planning And Design (Primary and control plant) Automation/SCADA Interconnectivity Breaker placement Protection Work/Contract Management Quality of build External Environment Lightning Winds Theft storms Vegetation Network Reliability Performance Measurement Methodology How and what we measure ?

  6. Key Technical Focus Areas • What is Eskom Dx Wires Business Focusing On ? • Reliability of Supply Improvement (RSI) Strategy • Increased Live work • System security and Maintenance of current QOS levels • Holistic asset management (AM) • Reduction of equipment/conductor theft • Improved outage management • Reduced response times to faults • Increased network visibility and control (SCADA) • Quality of workmanship and build • Reduction of non-technical losses • Value adding line inspections and vegetation management • Accelerated woodpole replacement • Network strengthening

  7. Reasons for Outages in Central Region • Cable faults predominantly in the Sandton area mostly due to external contractor damage • Cable and other equipment theft • Overhead line and tower theft • Normal equipment failure • Project related outages • Severe weather conditions • Overload due to illegal connections

  8. Current Challenges and Future Risks • Network limitations in the Vereeniging and Randfontein area. Projects to address this in progress. • Load growth in electrification areas. • Increased construction activities e.g. Gautrain • Rapid development. • Statutory Authority approvals (DWAF, GDACE, Road agencies etc. Approvals up to 9 months) • Acquisition of state owned land.

  9. Current Strategies • Network reliability improvement strategy (25% in 5 Years) • Focus Maintenance/Refurbishment effort on poor performing/worst impact feeders from a customer perspective. • Continuous capital investment. • Management of strategic and critical spares. • Annual maintenance plan (Normal operation) • Increased network visibility and communication.
