off-shore wind power.
The targets:
  • Medium target of 5 GW by 2022.
  • Long term target of 30 GW by 2030.

Significance of the move:
Offshore wind power would add a new element to the already existing basket of renewable energy for the country.

Why off- shore wind farming is beneficial?
The offshore wind faming is attractive because of several reasons such as stronger winds for efficient generation of power; no impact on real estate value of land as in case of onshore wind farming; its ability to fulfil the demand of the heavily populated coastal regions and no significant environment costs.

Challenges:
  • It is difficult to install large wind power turbines in open seas. Offshore wind turbines are of much larger dimensions and capacities than onshore turbines.
  • The PLF (plant load factor) of off-shore wind turbines will be higher than the on-shore projects.
  • The cost per MW of off-shore wind power project will be higher by 50-100% as compared to on-shore projects depending on the water depth.
  • Further deep sea wind farms come with the challenges of assigning no-go areas for commercial shipping. There would be a need to devise new lanes, proper lightning for ships to pass on.

National Off-Shore Wind Policy:
  • The Ministry of New & Renewable Energy had notified National Off-Shore Wind Policy in October 2015 to realize the offshore wind power potential in the country.
  • With this, the Ministry of New & Renewable Energy (MNRE) has been authorized as the Nodal Ministry for use of offshore areas within the Exclusive Economic Zone (EEZ) of the country and the National Institute of Wind Energy (NIWE) has been authorized as the Nodal Agency for development of offshore wind energy.
  • Government has paved way for development of the offshore wind farms up to the seaward distance of 200 Nautical Miles (within its Exclusive Economic Zone) from the base line.
