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 600100 ed@cwet.res.in

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 India Mullaikadu, 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)

What can we Design ? in HAWT P wind = C p 1/2 ρ AV 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 3 C p efficiency (“Betz” max. = 16/27) = 0.59 4 10/4/2013

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

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

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

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 10/4/2013 26

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
