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

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)

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

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.

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)

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.

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
