CSP Today South Africa 2015 14 April 2015 WWW.SASTELA.ORG ”Promoting the CSP Industry in Southern Africa” WELCOME to CSP Today South Africa 2015 Cape Town Technical site assessment: X Poor DNI X Grid access concerns X I&AP objections X Avian interaction possible √ At least the site is flat... WWW.SASTELA.ORG ”Promoting the CSP Industry in Southern Africa” SASTELA – Introduction ! The Southern Africa Solar Thermal and Electricity Association (SASTELA) represents industry involved with electricity and heat generation using solar concentrating systems. ! Established in 2010. ! Founding members: Exxaro Resources, DBSA, IDC, Siemens, Areva Solar and Emvelo. ! The Association currrently comprises 16 world leading engineering, construction and CSP companies. ! Founding member of the World Solar Thermal Electricity Association (STELA-World) and member of the South African Renewable Energy Council (SAREC). WWW.SASTELA.ORG ”Promoting the CSP Industry in Southern Africa” SASTELA’s – Objectives ! Promote the roll out of CSP Power Stations for the production of sustainable peak, mid merit (shoulder) and baseload solar thermal electricity in Southern Africa. ! Promote CSP in Southern Africa at policy and administrative levels (local, national, regional & international) aimed at harnessing Africa’s vast Solar Thermal Fuel (Direct Normal Irradiation (DNI) ! Promote the manufacture and industrialisation of CSP components in Southern Africa and to explore the ”airbus model”, where SADC countries can manufacture different CSP components for Solar Thermal Power Stations.

Pumped storage Coal & Nuclear CSP IPP programme ! CSP is a renewable / conventional hybrid. ! It is dispatchable. Lowest LEC found with a significant storage volume. ! CSP is scaleable and can provide large power generation units ! It can operate at any point on the supply curve. However, the best value can be obtained when viewed as an Integrated Generation Option, providing both baseload and peak power at a large scale.

Values in the table, for coal and nuclear, are unajusted at R10=US$1, as per 2013 when report was issued. ! Comparing the Round 3.5 CSP tariff with LEC numbers for other conventional technologies (coal, nuclear) shows that CSP is cost competitive with conventional options, if CSP is viewed as an Integrated Generation Option (IOP) – providing both Baseload and Peak electricity. WWW.SASTELA.ORG ”Promoting the CSP Industry in Southern Africa” CSP considerations ! Leveling the playing field between CSP and conventional options by increasing the plant size (above 100 MW) and lengthening the PPA term (similar to the proposed terms for the coal IPP program, i.e 30 years) will result in the further reduction of CSP tariffs. ! CSP has the potential for large scale manufacturing, industrialisation and localisation. Increased commitment to CSP as an Integrated Generation Option will enable government to meet the objectives of IPAP and the Black Industrialisation Policy and could contribute immensely to the goverment’s war room driven 5 Point Plan. ! CSP plants are modular and can be constructed within a period of 24-36 months. This will allow South Africa to introduce much needed baseload and peak power into the grid within a short space of time. Four providers, constructing 300MW each, delivers 1200MW within 3 to 4 years. There should be consideration for awarding multiple projects to Bidders. WWW.SASTELA.ORG ”Promoting the CSP Industry in Southern Africa” Future in South Africa ! Government has shown significant commitment to diversifying the country’s supply through Four Rounds of the RE IPP programme. This is a clear commitment to the future and we expect the IPP programme to continue. What the industry does, however, need is the programme schedule going forward, to enable planning and development. ! Given decreases in the cost of CSP, the potential to obtain further cost reductions and the contribution that CSP could make as an Integrated Generation Option, we expect the allocation to CSP to increase in the future, compared with earlier rounds in the programme. ! Several sites are being developed by the major CSP players, totalling thousands of potential MW. ! Ability to connect to the Eskom Tx network is a contraint. The 2015-2024 TDP contains the expansion of the network around Upington and includes the proposed solar park, but does not support development in other areas. WWW.SASTELA.ORG ”Promoting the CSP Industry in Southern Africa” Regional potential ! The Southern African region has an excellent solar resource. ! Both Namibia and Botswana require new power generation and represent attractive investment environments. ! Given the decrease in CSP cost and its dispatchable nature, CSP can be a real option for both countries. ! Given the relatively small generation base, uptake will not be at the scale of the SA DoE RE IPP programme, however, projects are possible within the near term.
