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

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

  4. RENEWABLES IN INDIA * Industry estimate ** Assuming only 4% of Indian desert area of ~ 2,00,000 sq. km (Guj, Raj)

  5. Wind Power

  6. WIND POWER LEADS THE RENEWABLE REVOLUTION IN INDIA • Wind Power Mainstayof Renewables in India • Mature Market & Technology, various project developers in India • ~9645 MW installed capacity in India as on Dec. 08 : 5th 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 6-6.5 Cr / MW subject to project size, location, technology

  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 12-13 % • 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

  8. SOLAR POWER

  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. 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) • 11000 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. 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 - 0.27 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. CSP - TOWER TECHNOLOGY PS 10 , Seville, Spain

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

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

  15. CSP - LINEAR FRESNEL TECHNOLOGY, ALMERIA AND AUSTRALIA

  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 40000 MW by 2020 • Already crossing the target of 5000 MW set for 2015

  17. PROJECTED COST REDUCTION IN CSP CSP Electricity Cost as a Function of Cumulative Installed Capacity Huge electricity costs reduction potential in immediate future

  18. MNRE / SERC THERMAL – INCENTIVE/TARIFF MNRE has a notional cap of Rs 13/kWh as the maximum combined revenue inclusive of tariff and incentive

  19. SOLAR POWER – PV TECHNOLGY – Grid connected

  20. SOALR CELL TECHNOLOGIES

  21. CONCENTRATING PV (CPV) • CPV – Latest Emerging PV technology • Uses Space quality solar cell with high efficiency and optical lenses for concentration ( High Concentration Ratios: 200-1000) • Very High Efficiency ( 25-30%), higher energy output compared to PV (~ 12 -15%) • 3 MW sanctioned in Puertallano, Spain by ISFOC. Partly commissioned and under construction. First CPV project in the world. • More than 20 MWp production line in Pipe Line • Also holds promise for cost reductions in the very near future. (Disadvantage is: no possibility of storage) Optics for concentrating Sunlight, HCPV

  22. PV- SILICON (CONVENTIONAL) NELLIS SOLAR PLANT 14 MW, NEVADA

  23. CONCENTRATING PV (LOWCPV AND HIGHCPV) HCPV Testing Seville, 1.2 MW LCPV Plant

  24. COST REDUCTION LEARNING CURVE AND POSSIBILITIES IN CPV Energy Costs in AUS $/MWh

  25. WORLD’S FIRST CPV INSTALLATIONS, PUERTALLANO, SPAIN

  26. MNRE / SERC PV – INCENTIVE/TARIFF MNRE has a notional cap of Rs 15/kWh as the maximum combined revenue inclusive of tariff and incentive
