Wind Energy Fundamentals Indian Wind Energy Scenario Wind Energy Resource and Potential  India’s Commitments at COP26 (Glasgow)  To raise the non-fossil fuel-based energy capacity of the country to 500 GW by 2030  To meet 50% of the country’s energy requirements using renewable energy sources by 2030  To reduce the total projected carbon emission by one billion tonnes between now and 2030  To reduce 45% carbon intensity by 2030, and  To become carbon neutral and achieve net-zero emissions by 2070 Pacific Africa and Middle East Currently has the fourth highest wind installed capacity in the world with total installed capacity of 39.25 GW (as on 31st March 2021) Expansion of the wind industry has resulted in a strong ecosystem, project operation capabilities and manufacturing base of about 10,000 MW per annum Generated around 60.149 Billion Units during 2020-21 Promotion by Government Private sector investment by providing various fiscal and financial incentives such as Accelerated Depreciation benefit concessional custom duty exemption on certain components of wind electric generators Generation Based Incentive (GBI) Scheme was available for the wind projects commissioned before 31 March 2017 Technical support including wind resource assessment and identification of potential sites through the National Institute of Wind Energy, Chennai To facilitate inter-state sale of wind power, the inter-state transmission charges and losses have been waived off for wind and solar projects to be commissioned by March, 2022 Issued Guidelines for Tariff Based Competitive Bidding Process for Procurement of Power from Grid Connected Wind Power Projects - enable the distribution Licensees to procure wind power at competitive rates in a cost effective manner  Potential of Wind Energy in India National Institute of Wind Energy (NIWE), has installed over 800 wind-monitoring stations all over country NIWE issued wind potential maps at 50m, 80m, 100m and 120m above ground level Recent assessment indicates a gross wind power potential of 302 GW in the country at 100 meter and 695.50 GW at 120 meter above ground level S.

Ministry set a target of 5.0 GW of offshore wind installations by 2022 and 30 GW by 2030 which has been issued to give confidence to the project developers in India market. Absence of any obstruction in the sea offers much better quality of wind and its conversion to electrical energy. Offshore wind turbines are much larger in size (in range of 5 to 10 MW per turbine) as against 2-3 MW of an onshore wind turbine Cost per MW for offshore turbines are higher because of stronger structures and foundations needed in marine environment Desirable tariffs can be achieved on account of higher efficiencies of these turbines after development of the eco system  Off-shore Wind Energy – Global Scenario Global Scenario Globally offshore wind is about two decades old history with the first offshore wind turbine in Denmark in 1991 which has been decommissioned in 2017 As of now the total installation is about 35.3 GW in 18 different countries of which important ones are- UK (10428 MW), China (9996 MW), Germany (7689 MW), Denmark (1701 MW), The Netherlands (2611 MW), Belgium (2261 MW), Sweden (192 MW) Capacity additions in last four years stands at 57% of the total capacity out of which 6358 MW commissioned in 2020, 4679 MW in 2019, 4792 MW in 2018 and 4495 MW in 2017 Identified Offshore Wind Zones for Initial Project Development Based on the preliminary assessment from satellite data and data available from other sources eight zones each in Gujarat and Tamil Nadu have been identified as potential offshore zones for exploitation of offshore wind energy. Initial assessment by NIWE within the identified zones suggests 36 GW of offshore wind energy potential exists off the coast of Gujarat only. Further, nearly 35 GW of offshore wind energy potential exists off the Tamil Nadu coast Measurement campaign deploying Light Detection and Ranging (LiDARs) at the identified zones off the coast of Gujarat and Tamil Nadu. One LiDAR was commissioned in November 2017 for Offshore Wind Resource assessment in identified zone-B off the coast of Gujarat nearly 25 km away from the port of Pipavav. Two years data collected from the deployed LiDAR has been analyzed and the report is published at NIWE’s website As per the report, the annual average wind speed at the locations is observed to be 7.52 m/s at 100m hub height. measures all essential incoming wind conditions, including rotor average wind speed, wind direction, shear, and turbulence, at distances of up to 200 meters from the turbine rotor. This enables the turbine control system to achieve the best possible efficiency of wind energy production LIDAR positioned on the wind turbine blade Oceanographic, Geophysical and Geotechnical studies In addition to the wind data, the viability of offshore wind projects also largely depends on the condition of site in terms of oceanographic data, geophysical and geotechnical data. Ministry has planned to carry out the required study in this regard through NIWE and provide the basic data to the stakeholders before commencement of the bidding so as to mitigate the risks. Geo-physical Survey for 365 Sq. km (Gujarat) for 1.0 GW project capacity in Gujrat has been completed. One rapid EIA has also been carried out for this site. The first 1.0 GW offshore Wind Energy Project The first offshore wind energy project of 1.0 GW capacity was planned in the identified zone-B off the coast of Gujarat in order to bring the economy of scale and localization of necessary ecosystem for offshore wind energy sector. In principle (stage-I) clearance as per the National offshore wind energy policy from relevant Ministries/Departments for a 1.0 GW offshore wind energy project in Zone –B off Gujarat coast has already been obtained. Expression of Interest (EoI) for the first offshore wind project of 1.0 GW capacity off Gujarat coast has been floated on 10.04.18 by NIWE. Thirty five International/Multinational and Indian Developers/OEMs have participated in the EoI and subsequent consultation process who provided their inputs for bidding process. Ministry has constituted a committee to finalize a roadmap for development of offshore wind energy in the country along with the upcoming projects.
