1 KM NASSIEP CEO SANEDI Role in Development of CSP Industry in SA

2 Contents Who or what is SANEDI? The Objectives of SANEDI History of CSP in South Africa Key Research Areas underway in SA SANEDI proposal on RECORD and CSP Demo Project Conclusions

3 Objectives SANEDI is created for the sole purpose of assisting the DoE to achieve its strategic objectives as set out in the National Energy Act, 2008 (No. 34 of 2008), i.e.  Promote diversification of energy supply  Ensure emerging energy technologies are incubated and commercialised  Ensure appropriate human capital is developed to support new industries  Stimulate innovation in energy R&D, introduce next wave of generation capacity in SA

4 Strategic Orientation Set up R&D programmes and centres at universities where potential already exists – strengthen this capacity and turn into world class innovation centres In the medium to long term create capacity to undertake research, development and demonstration in-house in strategic areas Develop, demonstrate and prepare bankable projects for new energy technologies Where required, equity may be taken in a particular project, along the lines of a PPP

5 Reasons for the formation of SANEDI Government concerned over decline in energy R&D capacity Too many technologies and initiatives caught up in the so-called “Valley of Death” State requires an incubator for energy technologies to ensure that they are rigorously tested and developed to the point of commercialisation State has put in place a strategic partner for PPP projects for demonstrating and piloting emerging technologies

14 Why CSP in South Africa? Resource Assessment points to one of the best insolation sites in the world, in the Northern Cape Other renewable energy technologies do not provide for the same level of energy storage, hence unable to provide baseload power (cf. Wind (load factor of about 30%), versus CSP Receiver (load factor of 68%)) Rising price of electricity creating opportunity for CSP Manufacturing opportunities are sizeable and consistent with SA skills set Green job potential is significant

15 History of Eskom CSP in South Africa 1997  Prefeasibility study completed – highlights value of CSP 1998  Eskom introduces SABRE-Gen, a programme designed to facilitate the uptake of large, grid- connected RE  Eskom partners with NREL to investigate CSP potential 1999/2000  Sunlab completes technology screening of CSP options, discarding solar chimney, and highlighting use of Central Receiver and Trough 2001  Detailed engineering design for Central Receiver project commences 2002  Eskom commissions 25 kWe Dish Stirling system at DBSA offices, to co-incide with World Summit on Sustainable Development 2003  White Paper on Renewable Energy is approved by Cabinet, setting target for RE 2004 –  Ongoing work on CSP project in Upington, including EIA, site selection

16 SOUTH AFRICA SOLAR RESOURCE (The potential of concentrating solar power in South Africa, Thomas P. Fluri) One of the best solar resources in the world. Five out of the nine provinces of South Africa, Northern Cape, North West, Free State, Eastern Cape and Western Cape, include areas with an annual average DNI higher than 7.0 kWh/m2/d. DNI map shown below

17 The National Energy Regulators of SA (NERSA) announced a feed-in tariff system (REFIT) for renewables in March Amongst other resource options, the REFIT scheme caters for CSP. An initial tariff of $0.28/kWh was set. This is being reviewed, with an updated tariff expected by the end of this month. It is expected that the CSP tariff will not be technology specific, but rather inclusive of all technologies. Hurdles to entry will be set based on the DoE’s New Generation Regulations Regulatory Framework

19 Comparative Electricity Prices (Predicted)

20 Numerous CSP technology options exist today, but only few are proven. Further, only few companies have experience in the installation, operation and maintenance of these power plants Current programme approached should focus on proven technologies for implementation and grid supply, together with a strong R&D programme, encouraging and enabling the installation of pilots around new technologies. Established international market players should be encouraged. CSP Technology Status – High Level Mature (In operation right now at a capacity ≥10MW) Emerging (Constructed at pilot level and is generating (or has), no operational plant ≥10MW) Future Research projects  Parabolic troughs (with / without molten salt storage)  Steam towers  Molten salt towers  CLFR systems  LFR systems  Dish Stirling systems  Steam troughs  Molten salt troughs  Air receivers  Other State of Technology
