Transcription

1 Wind Power : the way forward in India History and Status of W.E Road Map for 15 years Gaps in existing systems Issues of supply chain, manpower, and grid stability Dr.S.Gomathinayagam Executive Director Centre for Wind Energy Technology Chennai ed@cwet.res.in

2 History of wind energy in India Two Oil Shocks of 1970s gave CASE-1981 (Commission on Alternate Sources of Energy) under DST DNES-1982 (Department of Nonconventional Energy Sources) MoEnergy First Demonstration wind farm in India Mullaikadu, Tuticorin, kW (BHEL) x55kW (WindMatic)

3 History of wind energy in Veraval Gujrat India Demonstration wind farms in 11 states 73MW ( 0.4%) MNES 1992 Ministry of Non-conventional Energy Sources MNRE 2006 Ministry of New and Renewable Energy (MoState-Independent charge) MNRE (Independent Cabinet ranked Ministry)

4 What can we Design? in HAWT P wind = C p 1/2 ρav 3 Power (translation) = Force x Velocity = (P=F V) Power (rotation) = Torque x rotational speed = (P=T x Ω) C p Power(Energy) = Kinetic Energy x mass flow rate = (P= KE*m) A P wind = C p 1/2 pav /4/2013 C p efficiency ( Betz max. = 16/27) = 0.59

5 20000 Cumulative Installed Capacity in India (MW) STATUS of wind energy in India, 19GW (July 2013)

6 3500 Annual Capacity addition in India (MW) STATUS of wind energy in India, Annual 1.7GW in ACCELERATED DECREASE in CAPACITY ADDITION GW to 1.7GW??????

7 Cumulative Rated Capacity/WTG Average rated capacity of wind turbines (last ten years) Demo = 184 kw Private= 843 kw CUF increases With MW class STATUS of wind energy in India, Average Rated Capacity/WTG Turbines

8 Development in Size Andhra Pradesh Goa Gujarat Karnataka Kerala Madhya Pradesh Maharastra Orissa Rajasthan Tamilnadu Year Maximum Capacity kw kw kw kw STATUS of wind energy in India WTG-capacity kw kw kw kw kw kw kw kw

11 Statewise Cumulative Installed capacity (MW) STATUS of wind energy in India Andrapradesh Gujarat Karnataka Kerala Madhyapradesh Maharastra Rajasthan Tamilnadu

12 Statewise Cumulative Generation (MW) STATUS of wind energy in India NO AD Private profit to power Public Grid Andrapradesh Gujarat Karnataka Kerala Madhyapradesh Maharastra Rajasthan TamilNadu Effect anymore AD is welcome For small investors Let IPPs Sell WTGs like RealEstt Urban Flats?

14 STATUS of 18 Manuf. 43 WTGs in India ; Is there a WTRAI? Nacelle 100% Indian By GoI policy Assembly Gear 37.5% Indian,( US, Finland, Spain UK, China, Germany) Generator 44.2% Indian,( US, France, Spain Swiss, Italy, China, Germany) Controls 42.9% Indian (Denmark, Germany, US) Blade 38.9% Indian ( Finland, Spain Denmark, China, Brazil) GREAT OPPORTUNITIES TO BE No.1 in WTG Manufacturing overtaking China in Quality and in Reliability ; ARAI did gave affordable but usable CAR

16 Infirmity? Nature + man made design of power curve Excess WIND Good TURBINE Operating GRID LESS OR NO WIND Wind below rated capacity

17 POWER and ENERGY, RESEARCH NEED INDIA SPECIFIC DESIGNS? for Site Specific of WTG WIND M/C operation POWER WIND MACHINE- SPECIFIC 12-17m/s SITE- SPECIFIC 6-7 m/s

18 WE-Road Map for 15 years Investment Grade Wind Resource for large 225kW+ and Small WTGs National Wind Mission atleast till 2020 Consortium mode cost reduction Higher Wind power with forecasting & Energy storage techniques (Wind Must) Evacuation and tariff payment Guarantee Offshore Wind Power realisation (Multi-purpose Projects) Offgrid Wind-solar Hybrids Focussed Exclusive R&D to address issues Full exploitation of Manuf.Capacity 5000MW/year Consolidation and sustaining Supply Chain Effective and barrier less Policy support (with WRPO/REC)

20 Plug&Charge EOV urban parking AREAS & Wind to Water/Hydrogen in remote off grid locations Excess Wind USAGE

21 No Land issues 20-30% more No noise Opportunity : offshore wind power

22 New Solar /Wind on your Roof top will cut your EB bill : Net-metering in Tamil Nadu

23 Identify Gaps in current systems Critical Component supply / FOREX Standards for Grid Connection of WE Issues of Power Quality Lack/Attrition of Skilled Manpower Fly by Night Operators /Quality&AMC Threat of updated technology denial over long term in the absence Indigenous R&D Land costs and Governmental procedures

25 www: Win With Wind is NEED of HOUR to Power All, Ever Wind is not mined & use needs MINDSET Wind to hydrogen for mobile-energy Wind is not transported Wind need not be stored Wind is abundant, giving Green Power Wind is freely owned Wind power sustains drinking water Wind is completely renewable by NATURE

26 Wind certainly Works No threat of cost escalation No threat of hoarding No threat of transport-driver/ miner s Strike No threat of depletion as it is renewable No threat of Pollution to environment Wind is sustainable with infirmity managed with Focused Political and societal WILL 10/4/

27 NATIONAL WIND MISSION NEEDED Wind farm cooperatives with farmers as owners (rural corporate) as in Denmark Societal Will and awareness of long term sustainability and energy security Sustained Political Will for wind onshore/offshore Sustained Policy directives for extended period for self-sustained green energy devp. Promotional measures for Capacity building in India for (offgrid/wind solar/grid-tied ) roof top or hill top ( net metering seriously) Augmented Clean energy fund from CSR stream & Citizens

28 THANK YOU FOR YOUR KIND ATTENTION WEB SITE : CWET.RES.IN NATIONAL WIND MISSION 2020 WHY NOT A WTRAI LIKE THE ARAI?
