1 1 World Institute of Sustainable Energy 07 February 2009, GERC, Ahmedabad Overview of RENEWABLES & SOLAR TECHNOLOGIES

2 2 RENEWABLES: THE BIG BUSINESS OPPORTUNITY Peak oil, price volatility of fossil fuels, projected depletion Renewables changing from non-conventional to becoming mainstream Reducing prices, Low Risk and Assured Returns for renewables, will be cost competitive with conventional power in near future All large MNCs have entered or are entering renewables sector Wind Power – CAGR ~ 25% Solar Power – CAGR ~ 30-40% Investment in renewables in 2007 was $100 billion (including corporate take overs) Increasing venture capital flow into the sector Maximum global research funding flowing to renewables Renewables is and will be even bigger business in the future

3 3 RENEWABLES – GLOBAL SCENARIO (Figures exclude large hydropower, which itself was 15 % of global power generation) Renewables represent 5 % of global power capacity 3.4 % of global power generation. *$71 Billion is investment in power generation. Total R.E. Investments add upto $100 billion *

4 4 RENEWABLES IN INDIA Estimated medium-term (2032) potential and cumulative achievements as on No.Sources/Systems Estimated Potential (MW) Cumulative Achievements (MW) 1Biomass Power (Agro residues & Plantations)61, Wind Power *9521 3Small Hydro Power (up to 25 MW)15, Cogeneration (bagasse)5, Waste to Energy Solar Thermal Power (CSP)200000**Nil 7Solar PV and CPV200000**2.12 Total 5,83,700 13,450 * Industry estimate ** Assuming only 4% of Indian desert area of ~ 2,00,000 sq. km (Guj, Raj)

6 6 WIND POWER LEADS THE RENEWABLE REVOLUTION IN INDIA Wind Power Mainstay of Renewables in India Mature Market & Technology, various project developers in India ~9645 MW installed capacity in India as on Dec. 08 : 5 th Largest in the world, Third largest annual market after USA & China (1800 MW in 2008) Large untapped potential in India ~ 65,000 – 100,000 MW Technologies: Synchronous and Asynchronous Generators (with and without gears), New hybrid technology to be introduced Turbine unit sizes: 500 kW to 1.65 MW, may go up to 2.0 MW in near future Leading States: Tamil Nadu – 4200 MW, Maharashtra – 1800 MW, Gujarat 1400 MW Costs ~ Rs Cr / MW subject to project size, location, technology

7 7 TARIFF / RPS/ GRID ISSUES Project costs were going up due to rise in material costs, likely to come down because of recession, reduced demand Coal, Steel and other metal prices increased substantially during last two years ( > 15 % increase) Inflation touching 12 %, recently dropped to 5 to 6 % Interest rates going up fast touching to % Project viability important, Tariff revision was must Conventional power projects costs also increased during last 2-3 years Grid expansion through proper planning is the key for future capacity addition Global studies shows, NO TECHNICAL LIMITS for penetration, 100% renewable grid possible Forecasting services available, Need to be adopted in India BOOK: RENEWABLE ELECTRICITY AND THE GRID (2007), Earthscan publications Higher RPS % must be considered

9 9 TYPES OF SOLAR POWER Solar Thermal Power Generation Concentrating Type ( CSP) - Line Focusing system - Parabolic Trough Systems - Fresnel Trough Collector Systems - Point Focusing - Dish Stirling Systems / Concentrating Dish - Solar Tower Plants using central Receiver System Non- concentrating Type -Solar Updraft Tower Power Plants – Solar Chimney -Solar Pond Power Plants

10 10 A BRIEF LOOK AT CSP AND CPV Two emerging breakthrough solar technologies Solar thermal electric power generation (CSP) Total – 430 MW in operation -Tower (11 MW in Operation in Spain) – 03% -Trough (419 MW in Operation in USA)- 97% -Dish (Centralized and Stand Alone) -Linear Fresnel (~ few MW under construction) MW under construction or planned, globally Solar Photovoltaics -Conventional Silicon based (Crystalline and thin film) -Concentrating PV (CPV): The latest to emerge on the scene

11 11 CONCENTRATING SOLAR THERMAL POWER (CSP) Has the possibility of supplying base and peak load due to storage option Lower costs than PV/CPV Storage options greatly increase Plant Load Factor and dispatchable electricity Over 11,000 MW CSP in development throughout the world; Bulk of Projects under development in USA / Europe Feed-in Tariffs announced in few countries -Eg: Spain Euro / kWh for 25 years with adjustment for inflation. Re-look at Tariff once 500 MW installed. In India, over 500 MW Thermal Power project proposals with MNRE under the new incentive scheme. Max Rs 10/kWh incentive under MNRE policy About Rs 13/kWh as tariff including SERC tariff

12 12 CSP - TOWER TECHNOLOGY PS 10, Seville, Spain

13 13 CSP - TROUGH TECHNOLOGY, PROJECTS IN USA, SPAIN

14 14 CSP - DISH TECHNOLOGY (CENTRALIZED AND STAND ALONE) Dish-Sterling Engine

15 15 CSP - LINEAR FRESNEL TECHNOLOGY, ALMERIA AND AUSTRALIA

16 16 11,000 MW OF CSP CURRENTLY UNDER DEVELOPMENT USA, Mexico, Spain, Italy, Portugal, France, Israel, Egypt, Algeria, Greece, Morocco, SA, China, Australia, Iran, UAE Conservative projection of global installation targets: 5000 MW by 2015 and MW by 2020 Already crossing the target of 5000 MW set for 2015
