- 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.
- 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.
- 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.
