    • 1. Tamil Nadu Wind at Crossroads – The Way forward March 20, 2014 Chennai, India
    • 2. India – 5th Largest global wind market Wind in Tamil Nadu 2 91,424 61,091 34,250 22,959 20,150 10,531 8,552 8,254 7,803 4,772 - 10,000 20,000 30,000 40,000 50,000 60,000 70,000 80,000 90,000 100,000 InstalledCapacity(MW) Top 10 Countries - Cumulative Installed Capacity(MW) As of 31 December 2013 Source : Global Wind Energy Council

    • 4. Tamil Nadu – Exceeding Potential Wind in Tamil Nadu 4 Source : C-WET Installable Potential : 5374 MW(@ 50 m agl) – Actual Installations : 7,251 MW(31.01.2014)
    • 5. Tamil Nadu - Wind dominates in renewables Wind in Tamil Nadu Source : Central Electricity Authority Thermal, 10,0 64 Nuclear, 524 Hydro, 2,182 Renewables, 7,946 Tamil Nadu - Installed Capacity(MW) Total : 20,716 MW As of 31 January 2014 Non- Wind 9% Wind 91% Share of Wind in Renewables
    • 6. Then why is at the Crossroads? Wind in Tamil Nadu 6 44 134 371 679 858 578 381 431 602 997 1,083 175 150 0 200 400 600 800 1000 1200 MW Annual Wind Capacity Addition in Tamil Nadu Source : MNRE, RESolve Analysis
    • 7. What led to the drop in installations? Wind in Tamil Nadu 7 • Withdrawal of Accelerated Depreciation Benefits • Temporary withdrawal of Generation Based Incentives(GBI) Policy and Regulatory • Rs. 3.51/kWh • One of the lowest among the leading wind states(Gujarat – Rs 4.23/kWh, Maharashtra – Rs. 3.78 to Rs. 5.67/kWh, Rajasthan – Rs. 5.18 to Rs. 5.44 /kWh) Tariff • Lack of Transmission Lines • Grid ManagementEvacuation
    • 8. Troubled Wind power evacuation Wind in Tamil Nadu 8 239 792 2,153 2,283 2,137 2,194 1,507 291 267 1,858 2,195 1,604 1,394 964 749 118 0 500 1000 1500 2000 2500 April May June July August September October November MillionUnits(kWh) Wind Power Generation in Tamil Nadu 2012-13 2013-14 • ~2500 Million Units less evacuation during the above period(2013-14) compared to previous year(2012-13) • Backing down of windmills - 6 to 22 hours per day during high wind season. “Must Run” condition not followed(Source: Indian Wind Power Association) • Loss of Rs. 3,000 Crores in Year 2013 for Wind Mill Owners (Source: Indian Wind Power Association) Source : SLDC
    • 9. Why is evacuation a problem? • Wind farms can be built in a few months • But erecting transmission lines can take years • Infirm nature of wind – Intra-day variation as high as 3000 MW • Grid stability and security issues • Challenge – balance the variations, operations of conventional power plant efficiently Wind in Tamil Nadu 9
    • 10. The Way Forward Wind in Tamil Nadu 10
    • 11. What could be done? Wind in Tamil Nadu 11 • Restoration of Accelerated Depreciation Benefits • Generation Based Incentives(GBI) – Already restored Policy and Regulatory • Make tariff more attractiveTariff • Expedite Transmission lines • Improve Grid Management capabilitiesEvacuation
    • 12. Initiatives to improve evacuation • Dedicated Sub-stations by TNEB • 23 Sub-stations in Tirunelveli area • 21 Nos. in Udumalpet area • Green Energy Corridors by TANTRASNSCO • Phase-I – 740 km, 400 kV Transmission lines with 2 new 400 kV substations. Expected date of commissioning March 2014. • Phase-II – 445 km, 400 kV Transmission lines with 4 new 400 kV substations. • Phase-III –Proposed. All the generating stations of wind energy are proposed to be connected with the high capacity Transmission corridor proposed in Phase – I & II. Wind in Tamil Nadu 12
    • 13. Other Opportunities Wind in Tamil Nadu 13
    • 14. Higher potential at higher hub heights State Name Installable Potential MW Andaman & Nicobar Islands 365 Andhra Pradesh 14497 Arunachal Pradesh* 236 Assam* 112 Bihar 144 Chhattisgarh* 314 Dieu Damn 4 Gujarat 35071 Haryana 93 Himachal Pradesh * 64 Jharkhand 91 Jammu & Kashmir * 5685 Karnataka 13593 Kerala 837 Lakshadweep 16 Madhya Pradesh 2931 Maharashtra 5961 Manipur* 56 Meghalaya 82 Nagaland * 16 Orissa 1384 Pondicherry 120 Rajasthan 5050 Sikkim * 98 Tamil Nadu 14152 Uttarakhand * 534 Uttar Pradesh * 1260 West Bengal* 22 Total 102788 Wind in Tamil Nadu 14 Revised potential : 14,152 MW at 80 m agl Vs Current installation of 7251 MW Source : C-WET
    • 15. Repowering • Tamil Nadu : A pioneer of wind power in India • Several sub-500 kW operational wind turbines • Low performing old turbines can be replaced with high performing new turbines • About 685 MW which is suitable for repowering in Tamil Nadu. (Source: World Institute of Sustainable Energy) Wind in Tamil Nadu 15
    • 16. Off-shore Wind • Draft “National off-shore Wind Policy” released in May 2013 • Potential of 1 GW each along the Rameshwaram and Kanyakumari coasts in Tamil Nadu. • Tamil Nadu has the opportunity to become a pioneer in the Off-shore wind segment as well. Wind in Tamil Nadu 16
    • 17. The Takeaways Wind in Tamil Nadu 17
    • 18. Tamil Nadu Wind – Down but not out.. • Down, because – Of non-availability of Accelerated Depreciation benefits – Low tariff – Evacuation • Not out, because – Evacuation Infrastructure being improved – Repowering – Off-shore wind – Revised higher potential Wind in Tamil Nadu 18
