SAPP COMPETITIVE MARKET OVERVIEW SAPP DAM Market opened for live trading on 15 December 2009 Market performance highlights as of 31st April 2011 14 437,000 MWh Sale and 338,000 MWh Buy bids received 42,000 MWh was matched on the DAM trading platform However only 29,000 MWh was traded or approximately 1% market share The remainder could not be traded due to transmission constraints SOUTHERN AFRICAN POWER POOL Average Monthly Market Clearing Prices as of 31st Apr 2011 Average Market Clearing Prices (MCPs) USD/MWhr 50.00 40.00 30.00 20.00 10.00 15 Apr-11 Mar-11 Feb-11 Jan-11 Dec-10 Nov-10 Oct-10 Sep-10 Aug-10 Jul-10 Jun-10 May-10 Apr-10 Mar-10 Feb-10 Jan-10 Dec-09 - SOUTHERN AFRICAN POWER POOL 7. CONCLUSION SAPP is making efforts to reduce carbon emissions In the long-term, high cost coal will be displaced by cleaner energy sources such as hydro, wind and solar Coal % to be reduced from 74% to 56%. Hydro % to be increased from 20% to 26% Wind and solar % to be increased from 0% to approx. 0.5% SAPP has reformed in line with world wide trends in the electricity sector To date SAPP has introduced a competitive power market in the form of a Day Ahead Market Intends to introduce other markets incl.
