Report to the UPDEA 39th General Assembly By How to prevent lack of Generation Capacity in SAPP SAPP Executive Committee Representative Tanger, Morocco 30 November 2007
General Information Demand and Supply in SAPP Rehabilitation and Short Term Projects Transmission Projects CONTENTS
GENERAL INFORMATION DR Congo Tanzania Angola Malawi Zambia Zimbabwe Namibia Mozambique Botswana Swaziland South Africa Lesotho Key Statistics • 12 Countries • 230 Million • Annual consumption 250 TWh • Electricity growth rate 3% p.a. • Generation mix • Coal 74.3% • Hydro 20.1% • Nuclear 4% • Gas/diesel 1.6%

The SAPP Planning Data is indicating that SAPP runs out of generation surplus capacity after the year 2007.
Peak Demand in 2006 & 2007 • Load shedding in ZESA, ZESCO and NamPower in 2006 at peak periods • Interruptible Load Contracts, Demand Market Participation and DSM utilised in ESKOM. (Experience in 2006) • This demonstrated that supply was not adequate • The 2007 indicates that actual generation reserve capacity were lower than normally planned. • Demand Side Management Initiatives have been initiated and supported

New Generation Projects in 2007 • ESKOM commissioned 2 x 190 MW at Camden in 1st quarter of 2007. • ESKOM commissioned 1050 MW – Commercial Operation was in May 2007 (OCGT). • TANESCO commissioned 100 MW GT at end of Sept 2007 at Ubungo. • SEB to commission 20 MW at Maguga before Dec 2007.
Priority Projects The SAPP priority projects have been agreed as follows: • Rehabilitation & associated transmission projects. • Short-term generation projects • Expected to be commissioned before 2010 • Completed feasibility studies • Approved Environmental Impact Assessment • Transmission projects • Medium to Long-term generation projects • Expected to be commissioned after 2010 • Most have no feasibility studies and EIA

UPDATE ON SAPP INTERCONNECTORS Mozambique - Malawi • World Bank approved the finances. • Detailed designs being done. • Commissioning to be in 2009. • CEC - SNEL second 220 kV Interconnector • Total Transfer capacity for the 2x220 kV lines would be 500 MW. • Zambian side finalized and to be funded by CEC. • SNEL to be supported by the World Bank.
UPDATE ON SAPP INTERCONNECTIONS Zambia-Tanzania-Kenya 330 kV line • Commissioning date shifted from 2008 to 2011. • Heads of Agreement to be signed by the 3 Governments at the end of Oct 2007. • Draft Power Purchase Agreement to be discussed by the 3 Gvts in Livingstone. • Initial power proposed to come from Zambia then other SAPP countries.
SAPP Capacity Expansion Plans • In order to avoid power shortages as early as 2007/8, the SAPP would have to spend US$4.3 billion to complete projects in progress and to rehabilitate some plants.
