1 The Eskom price adjustment Effective 1 July 2009

2 This presentation provides information on the 1 July 2009 the price adjustment and impacts in three areas: Background and overall Large power user tariffs Megaflex, Miniflex, Ruraflex and Nightsave tariffs Small power user tariffs Businessrate, Homepower, Homelight and Landrate

3 Operational expenditure Financing and access to finance Increase in Eskom costs Electricity generation costs Background on the Eskom price adjustment Effective 1 July % increase effective 1 July 2009 (including the environmental levy) 2009 Eskom application to the NERSA 2007 Eskom submission the NERSA for tariff restructure Increased tariff structures cost reflectivity Tariff component changes primarily to the large power user tariffs. No change to the Homelight tariffs The NERSA Approval of the tariff restructure in December July 2009 Eskom standard average tariff adjustment 1) Restructured tariffs 2) 22.7% Price increase (excluding levy) 3) 8.8% Environmental levy 4) Lower price increase to the poor

5 1 Restructure to the standard tariffs (max +2% per point of delivery ) Megaflex Municipal tariff

6 The restructured standard tariffs Submitted to the NERSA in August 2007, approved by the NERSA in December Implementation aligned to the price adjustment with the price increase. The main features of the structural changes are: 1.The unbundling of transmission and distribution network charges (only for large power user tariffs). 2.A move to the use of technical loss factors to differentiate energy costs instead of the previous voltage and transmission surcharges. 3.An increase to the voltage differentials between the high and low voltage network charges. 4.An increase in the energy rates and a commensurate decrease in network charges to reflect the higher cost of energy. Total impact of the tariff restructuring is 0.1%. The 2009/10 standard tariffs are the restructured standard tariffs in 2008/9 rand value plus the 1 July price increase.

13 Customer impacts from the 1 July 2009 tariff adjustments Customer electricity costs are primarily subject to their consumption load factor, voltage of supply and location of the supply (urban / rural). The high-load customer will experience the higher cost portion of the electricity price more. % of total costs in electricity tariffs

14 Customer impacts from the 1 July 2009 tariff adjustments The restructured tariffs have a higher increase to the energy rates than networks and retail charges Non-municipal Megaflex tariff at >132kV, Zone 0 Impact of ring-fencing key customer’s costs. Previously spread across the total base Energy related charges increasing the High-load factor customers’ impacts Higher impact in the high-demand season than the low –demand season Benefit from the removal of the >132kV Network access charge

15 0% LF 100% 2008/9 structure 2009/10 structure Env Levy on 2008/9 Env Levy on 2009/10 Rands High LF customers see a higher than average increase The 2009/10 restructured network costs reduced compared to 2008/9 and the energy costs for 2009/10 increased compared to 2008/9. Low LF customers see a lower than average increase Customers tend to compare 2008/9 excluding the Env Levy with 2009/10 including Comparing the impact of the price adjustment Customer comparison requiring understanding of the load factor and the impact of the environmental levy. Ample tools and information on the Eskom internet site.

16 Incremental electricity costs from the 2009/10 tariff charges The increase in the electricity costs is primarily from the higher energy charges.

17 Non-Municipal customer impact 2008/9 tariffs compared to new structures + 1 July increase Previous years’ prices during April to June. Lower increase due to adjusting 2007/8 prices with 34.2%

18 Non-Municipal customer impact 2008/9 tariffs compared to new structures + 1 July increase Previous years’ prices during April to June i.e. 35.9%

19 Non-Municipal customer impact 2008/9 tariffs compared to new structures + 1 July increase

20 Small power user tariffs Businessrate, Homepower, Homelight and Landrate

21 Rates including the environmental levy in 2009/10 Impacts for customers on the Homepower tariffs (average month) For residential customers on the Homepower tariffs, reduced consumption would also provide an advantage of lower electricity costs. The reduction in the network charges due to the tariff restructure provides some relief with an overall increase lower than 33.6%

22 Rates including the environmental levy in 2009/10 Impacts for customers on the Businessrate tariffs (average month) For small to medium sized commercial supplies, the incremental cost of electricity after the price increase is reduced for energy but higher on network charges. The average impact on the Businessrate tariffs in a typical month is lower than the price increase of 33.6%

23 Rates including the environmental levy in 2009/10 Impacts for customers on the Landrate tariffs (average month) Rural customers (e.g. farmers) see a lower than the 33.6% increase especially for the low consumption Landrate Dx tariff customers.

24 The increase in electricity prices is further reduced for those customers that receive FBE.
