• History and Status of W.E• Road Map for 15 years• Gaps in existing systems• Issues of supply chain, manpower,
and grid stability
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 Non-conventional Energy Sources) MoEnergy
• First Demonstration wind farm in IndiaMullaikadu, Tuticorin, 1984 55kW (BHEL) 1986 10x55kW (WindMatic)
History of wind energy in India
• 1985- Veraval Gujrat
• 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- 2009 (Independent Cabinet ranked Ministry)

Power (translation) = Force x Velocity = (P=F V)
Power (rotation) = Torque x rotational speed = (P=T x Ω)
Power(Energy) = Kinetic Energy x mass flow rate= (P= KE*m)
Pwind = Cp 1/2 pAV3
Cp efficiency (“Betz” max. = 16/27) = 0.59
Pwind = Cp 1/2 ρAV3

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)
Plug&Charge EOV urban parking AREAS & Wind to Water/Hydrogen
in remote off grid locations
Excess Wind USAGE
• No Land issues • 20-30% more• No noise
Opportunity : offshore wind power
New Solar /Wind on your Roof top will cut your EB bill :
Net-metering in Tamil Nadu
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
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
• 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
Wind certainly Works
2610/4/2013
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
NATIONAL WIND MISSION 2020WHY NOT A “WTRAI” LIKE THE “ARAI” ?
THANK YOU FOR YOUR KIND ATTENTION
