  3. 3. Strategic Benefits of Wind • Wind is a Renewable Energy resourceSecurity of • No Dependency on Fossil Fuels Supply • No Exposure to Fuel Supply Risks • No Exposure to Fuel Price Volatility • Non Polluting & Non Consuming Resource • Zero C02, S0x, N0x and other atmospheric pollutantsEnvironmental • Zero Water Consumption • No Waste products (i.e. ash, dust, waste water, spent fuel) • No Waste Disposal Cost • Zero Short Run Marginal CostFinancial • Very Low decommissioning and rehabilitation costs • Low O & M costsTransmission • Coastal Location, closer to load centre resulting in reduced line losses
  4. 4. Project SERE Background• Eskom’s R&D research into cleaner technologies led to the commissioning of demo wind farm (Klipheuwel) in 2003,• Govt released RE strategy with target of 10 000GWh by 2013• Favourable data and key learnings from the demo plant coupled to independent studies by GTZ, CSIR indicated considerable distributed potential of Wind in South Africa,• In 2006 Eskom Board approved 100MW Wind project on the West coast• As with many projects in the world, the project was delayed due to funding constraints• NERSA released REFIT as an incentive mechanism in 2009 [Source: Tennessee Valley authority]• Funding approvals by the Clean Technology Fund and other Multi Lateral Development Banks enable resumption of the project 2011/01/21 4
  5. 5. Global Wind Market &Technology Progression Three-bladed, upwind, variable-speed, pitch-regulated turbines currently predominate onshore. 1.5MW de-facto standard in 2008/09 WT technology is different for offshore projects: there are strong reasons why individual turbine size is significantly larger, and turbines of 5 MW and more are being aimed at this market The principal design drivers are now grid compatibility, cost of energy (which includes reliability), acoustic emissions, visual appearance and suitability for site conditions. Growth in size of commercial Wind Turbine Generators Source: Garrard Hassan 2011/01/21 5Global installed capacity has been increasing at an average of 35 per cent since 2005

  7. 7. Overall growth drivers Key growth drivers Potential barriers to growth•Europe • High CO2 price due to Kyoto protocol • Public resistance against onshore turbines • EU regulations and subsidy schemes • Political support for other renewable technologies • Currently high oil and gas prices • Ramp-down of nuclear power plants•US • Political desire for energy independence, e.g., the “fear factor” • Limited grid capacity to key wind areas vis-à-vis Middle East • Increasing energy demand • Currently high oil prices•China • Strong increase of power demand requires fast installation of new • Overall weak transmission capacity capacity • Weak domestic industry • Environmental problems/wish for “clean air” • Transportation issues for larger WTGs • Will to foster strong domestic industry•India • Strong increase in power demand • Differing regulations across provinces • Independence from highly • Very weak grid in some areas unreliable grid • Transportation issues for larger WTGs • Tax saving schemes 2011/01/21 7Source: Mckinsey

  13. 13. Case Study: Germany OverviewGermany has one of the largest installed bases inEurope, but in 2009, it had to forego its secondranking in the world to make way for China’s blazinggrowth. The German wind energy market blossomedearly in the 21st century and later growth slackenedas other regions began promoting renewables moreaggressively.The wind technologies market has proved to be alucrative export business for Germany. Thepresence of major wind energy companies hasfurther added to the country’s strength. About 85per cent of the components manufactured areexported to other countries, generating more than€7.2 billion as revenues. Backed by a solidengineering base, Germany is a haven for windturbine/components manufacturing companies asan export base. 2011/01/21 13

What is required to nurture Wind in RSARegulatory ‘Govt needs to provide ‘ Bold line of sight ‘ Simplify some of the ‘Speed up approvals regulatory certainty for renewable targets complex processes’Framework required to provide Renewables.’ requirements’ guidance to NERSA, EIA industry’Incentives „Appropriate incentives required for ‘ Appropriate Incentives development of Renewables value chain in for development and RSA’ production of renewable energy’ 2011/01/21 15
