INDIA'S OFFSHORE WIND ENERGY TARGET : 2030

Recent Context

  • On 20 June 2018, the Ministry of New and Renewable Energy (MNRE) has set a target of installing 5 GW of offshore wind energy capacity by 2022 and 30 GW by 2030

About Offshore Wind Energy

  • Using wind mills, energy can be generated which will be completely carbon neutral and environment friendly. 
  • Wind energy today comes in two forms : onshore wind farms which are large installations of wind turbines located on land and offshore wind farms which are installations located in bodies of water.
  • Offshore wind farms use either fixed foundation turbines (built in shallow water) or floating wind turbines (built in deeper waters).
  • Offshore wind farms must be at least 200 nautical miles from the shore and 50 feet deep in the ocean.

Wind energy need in India

  • In India, since land is limited and population is ever increasing, large wind farms positioned over water bodies will be very useful.

Benefits of offshore wind parks

Wind Capacity Utilisation Factor (CUF)

  • It is equal to average output power divided by the maximum power capabilities. Offshore wind farms have higher CUF than onshore leading to longer operations hours.

India and Wind Energy

  • According to Global Wind Energy Council (GWEC) India's capacity to generate electricity from wind reached 39.2 GW a year in March 2021.
  • Another 20 GW is expected to be added up over next five year.

 

  • According to National Institute of Wind Energy (NIWE), total wind energy potential is 302 GW at 100 meter hub height and 695.50 GW at 120 meter hub height. 
  • 95% commercially exploitable resources are located in : Andhra Pradesh, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan and Tamil Nadu.

India and Offshore wind Energy

  • As per MNRE, India can generate 127 GW of offshore wind energy with its 7,600 km of coastline.
  • For achieving this india has announced its "National offshore wind energy policy" in 2015. MNRE is the nodal agency for the policy.
  • Gujarat & Tamil Nadu have been identified as potential offshore zones for exploitation of wind energy.

Way Forward

  • Following things should be done for making offshore wind energy sector profitable.

Renewable Purchase Obligation

  • Government-specified obligated entities such as power dis-coms, open access consumers and captive users can purchase clean energy as part of their consumption.

Lower Taxes

  • In India, the GST Law exempts electricity and power sales from GST. In contrast, wind power generation companies can't claim input tax credits when they pay GST on purchase/service rendered.

Demand Generation Provision 

  • Offshore wind farms should be given gaurantees of purchase for their power generation.
