1 SOUTH AFRICA IEA DSM 41 st EXCo Meeting 25 April 2013

2 The South African National Energy Development Institute mandate The Na#onal Energy Act, 2008 (Act No. 34 of 2008), Sec3on 7 (2) provides for SANEDI to direct, monitor and conduct energy research and development, as well as undertake measures to promote energy efficiency throughout the economy. 2

3 Some Key Facts MW GWh 4.7 m Maximum self- generated capacity Total produc=on Customers Build Programme MW Addi=onal capacity by MW Total capacity by 2026 Source: Eskom s Integrated Report 2011

4 South Africa s Current Capacity Mix

5 Planned Generation Expansion Project ProjecKons 11/12 FY 12/13 FY 13/14 FY 14/15 FY 15/16 FY 16/17 FY 17/18 FY 18/19 FY Total Grootvlei, (return to service) KomaK, (return to service) Arnot capacity upgrade, (coal fired) Medup,i (coal fired) Kusile, (coal fired) Ingula, (pumped storage) Sere wind farm, (renewable) TOTAL (MW) In addikon, Eskom has commenced the development of a 100MW CSP plant

6 Consumption per Sector Consumption Demand Agriculture 4% Transport 2% Residential 17% Mining 18% Residential 35% Mining 14% Commerce 10% Industry 49% Agriculture 4% Transport 2% Commerce 10% Industry 35%

7 SA Peak Consumption Periods 38 MW Summer & Winter load profiles Summer load profile is much flaaer, peak of GW, so if there is a constraint, the system is constrained for the enkre day Winter peak is much higher but for a shorter period : forecast this winter just under 37 GW Typical Winter Day Typical Summer Day 23:00 02:00 05:00 08:00 11:00 14:00 17:00 20:00 23:00 02:00! Most planned maintenance is done in summer, when demand is lower, so that maximum capacity is available to meet demand at winter peak. (Note: Southern Hemispere)! A colder-than-expected winter puts added pressure on the system: for every 1 degree Centigrade decrease in winter temperature, electricity demand increases by MW during the evening peak; a warmer than expected summer increases air-conditioning load and demand can increase by up to 400 MW.

8 Demand Savings Achievement MW 2000 Peak Demand Savings (MW) MW 0 Residential & Munics (incl SWH) Industrial & Mining 125MW Commercial & Corporates (incl GOV & SOC) 18MW Agriculture Approximately 3 073MW of demand savings claimed, but only 347MW were verified in FY 2012

9 Demand Savings - Commercial 80MW Commercial - Demand Savings as per year claimed Peak Demand Savings (MW) 60MW 40MW 20MW 0MW 54MW 23MW 17MW 17MW 8MW 4MW 1MW 1MW FY 2005 FY 2006 FY 2007 FY 2008 FY 2009 FY 2010 FY 2011 FY 2012 Commercial Sector has contributed 125MW to the demand savings!

10 Technologies - Commercial 100MW 94MW 80MW Peak Demand Savings (MW) 60MW 40MW 20MW 0MW Lighting & HVAC 12MW Shower Heads 12MW CFL Roll out 3MW 3MW 1MW 0MW 0MW Combo - SPP Demand Reduction Heat Pumps Process Opt SWH

11 Which How can Eskom How much help power me will implement an How energy long is technologies will Your project save? efficient solu=on? you implement? Funding Models (Who is it for?) the approval process? How and when are the rebates paid? Performance ContracKng* (Industrial) Aggregated Standard Product >30 GWh in 3 years Custom or hybrid solukon 3-4 Months (Industrial & Commercial) ResidenKal Mass Rollout (Residentail) ESCO Model 5 MW 1 MW Limited to specific products on a published list Limited to specific products on a published list 2-4 weeks 2-4 weeks (Industrial & Commercial) Standard Offer (Industrial & Commercial) Standard Product (Commercial) 1 MW Batches 1 MW Batches 250 kw 50 kw 0 Custom or hybrid solukon Limited to categories of technology on a published list Limited to specific products on a published list 6-18 Months Less than 2 months Less than 2 weeks 70% 10% 10% 10% * Pending finalisa=on of offer

12 Questions?! Duplication and/ or linkages to other initiatives:- Clean Energy Ministerial, (CEM); SE4All; IPEEC; Etc.?! Transition from DSM to IDM?! Value of joining at this stage?
