  1. Energy Security Masterplan – Phase 2 Presentation to the Parliamentary Portfolio Committee on Minerals and Energy 18 June 2008

  2. Introduction - Energy Masterplan • Cabinet approved Phase 1 of the Energy Masterplan • Phase 1 • Energy Security framework • Energy planning approach • Liquid fuels short to medium plan • Phase 2 • Electricity industry short, medium and long term plan • Integration areas between electricity and liquid fuels industries

  3. Introduction – Masterplan (Phase1) • The Masterplan seeks to: • achieve goals that have been set for the sector • Address current challenges • set security of supply standards • Set appropriate reserve margin • Incorporate climate change challenges

  4. Presentation Outline • Energy security framework • World electricity • RSA electricity • Development of the masterplan • Goals • Situational analysis • Demand forecast • Decision making • Interventions • Implementation matrix • Recommendations

  9. Security of Supply: Eskom Weekly Peak Demand (2006 vs. 2007)

  10. Definition: Generation Reserve Margin • The installed capacity of a power system must exceed the expected demand to allow for: • Generator breakdowns (forced outages) • Planned maintenance. • Load forecast uncertainty. • Security across the whole system, taking into account location of plant, location of load and regional transmission capacity. • The reserve margin is the amount of reserve capacity, expressed as a percentage of the annual peak load. • Example: If peak load = 40 000 MW and installed capacity = 44 000 MW, the reserve margin = 10%. • Smaller reserve margin increases the risk of supply interruption. Too large a margin results in unnecessary investment expenditure. Security vs. Cost.

  12. Electricity Masterplan

  13. Overview of masterplan • Sets goals for the sector • Sets key assumptions • Demand projections • Economic outlook • Formulated based on • White Paper on Energy • Regulatory policy framework

  14. Goals • Supporting economic growth and development • Improving the reliability of electricity infrastructure • Providing a reasonable priced electricity supply • Ensuring the security of supply as set by the security of supply standards • Diversifying primary energy sources • Increasing access to energy services • Meeting renewable energy targets as set in the White Paper

  15. Process followed • Generation • Adoption of a security standard for electricity supply • Appropriate investment level • Reserve margin • Transmission • Removal of transmission constraints WC, EC, KZN • Distribution infrastructure • Universal access • Bulk infrastructure

  16. Process followed • Acceleration of DSM and energy efficiency

  17. Planning assumptions • Detailed studies to be undertaken • Integration opportunities of electricity and primary energy sources • Nuclear energy is not considered • Imported electricity is not included • Assumed economic forecast • Consideration of driving forces and supply chain challenges

  18. Decision making considerations • Environmental Impact Assessments (EIA) • Site selection • Climate change • Renewable energy • Funding and resourcing • Skills management and development • Research and Technology • 2010 FIFA World Cup

  20. System demand focus

  21. Planned interventions

  22. In summary… • In the short-term • Demand side management • Peaking plants • Cogeneration projects. • In the medium to long-term • Mix of base load and peaking plants • Demand side management • Appropriate reserve margin

  24. Energy use by the residential sector Source: Energy outlook for South Africa - 2002

  25. Households of South Africa - 2001Main Energy Source for Cooking by Region Source: Stats SA - Census 2001

  26. Households of South Africa - 2001Main Energy Source for Heating by Region Source: Stats SA - Census 2001

  27. Facts on domestic consumption • Geyser – 4 kW • 10 million households of electricity • 2.5 million households own an electric geysers • This is equivalent to 10 000 MW (at peak)

  28. Planned Interventions • Short term • Demand side management • Energy efficiency • Fuel switching • Metering

  29. Planned interventions cont./ • Medium term • Generation • Cogeneration • Capacity expansion plan programme • Additional peaking power plants • Transmission • Expansion plans • Total system capacity and reliability plan

  30. Intervention plans cont./ • Medium term cont./ • Distribution • Maintenance and refurbishment • Expansion of distribution network • Electrification of households • Restructuring of the distribution sector

  31. Long term Plan

  32. Implementation matrix

  33. Summary of recommendations of phase 2 Masterplan • Reserve margin – 19% • Performance standard • “1 day in 10 years” • N – 1 transmission contingency • Regulation of the investment in maintenance and rehabilitation of infrastructure • Regulation of the quality of supply of electricity

  34. Summary of recommendations • Cabinet also noted: • Electricity price path, to finance the implementation of this plan; • Import/export of electricity; • Cogeneration, DSM and other energy efficiency measures; • Leveraging private sector participation (IPPs) in generation; • Supply of gas for primary energy diversification; • Attraction of energy intensive investments as a strategy for development

  35. Consultation • NERSA • Eskom • Municipalities • Organised labour • Organised business
