  • 2. Worldwide, wind energy is accepted as one of the most developed, cost-effective and proven renewable energy technologies to meet increasing electricity demands in a sustainable manner. While onshore wind energy technologies have reached to a stage of mass deployment and have become competitive with fossil fuel based electricity generation with supportive policy regimes across the world, exploitation of offshore wind energy is yet to reach a comparable scale 2shantanu@bhgassociates.com
  • 3.  In India preliminary assessments indicate prospects along the coastline of Kerala, Karnataka and Goa.  The wind resource data collected for the coastline of Rameshwaram and Kanyakumari in Tamil Nadu and Gujarat Coast shows reasonable potential.  A preliminary assessment suggests potential to establish around 1 GW capacity wind farm each along the coastline of Rameshwaram and Kanyakumari in Tamil Nadu.  India ranks fifth in the world in terms of installed wind energy capacity, with 18.5 GW as of January 2013. 3shantanu@bhgassociates.com
  • 4. There are two main maritime areas in which structures such as offshore wind farms can be built:  Indian territorial waters, which generally extend up to 12 nautical miles (nm) from the coast; and  Beyond the 12 nm limit and up to 200 nm (EEZ), where, under international law, India has right construct structures such as wind farm installations. 4shantanu@bhgassociates.com
  • 5.  Offshore wind energy projects in waters, in or adjacent to the country up to the seaward distance of 12 nautical miles from the baseline.  Research & Development activities may be carried out up to 200 nautical miles from the baseline (EEZ of the country). 5shantanu@bhgassociates.com
  • 6.  The preliminary Resource Assessment, Environment Impact Assessment (EIA) and Oceanography Survey will be carried out by the NOWA through specialist agencies, for demarcation of offshore wind energy blocks  Interested private players having expertise in studies and surveys may also be granted permissions on case to case basis, to collect data and have shared ownership on it, without any charges payable for the work. 6shantanu@bhgassociates.com
  • 7.  The offer of blocks will be made through an open International Competitive Bidding (ICB) process.  NOWA will be the contracting authority to lease the Sea Bed.  The successful bidders would require to enter into a contract with the NOWA for a stipulated time period. 7shantanu@bhgassociates.com
  • 8.  Offshore wind turbines are frequently located far from shore with greater potential for corrosion from exposure to seawater, and therefore must be designed more robustly (i.e., requiring less maintenance) than land- based turbines due to the high costs of transporting maintenance crews and replacement components to and from offshore wind plant sites. 8shantanu@bhgassociates.com
  • 9.  Centre for Wind Energy Technology (C-WET) has been established as an autonomous R&D institution by MNRE in testing of complete Wind Turbine Generator systems (WTGs) according to international standards (IEC, GL etc.) and verification of test reports for Onshore Wind Turbine Models.  Similar services will be rendered by C-WET for Offshore Wind Turbine Models. 9shantanu@bhgassociates.com
  • 10.  Length of coastline of India including the coastlines of Andaman and Nicobar Islands in the Bay of Bengal and Lakshadweep Islands in the Arabian Sea is 7517 km. A beginning can be made by conducting intensive wind survey to identify the potential windy region and Wind Farms started.  Offshore wind power can help to reduce energy imports, reduce air pollution and greenhouse gases (by displacing fossil-fuel power generation), meet renewable electricity standards, and create jobs and local business opportunities. 10shantanu@bhgassociates.com
  • 11.  The wind is much stronger off the coasts, and unlike wind over the continent, offshore breezes can be strong in the afternoon, matching the time when people are using the most electricity.  Offshore turbines can also be "located close to the power-hungry populations along the coasts, eliminating the need for new overland transmission lines". 11shantanu@bhgassociates.com
