Introduction
Why offshore wind power:
• Offshore wind power offers a plausible alternative as precious land resources required
for onshore wind projects are gradually becoming a major constraint.
• With exhaustion of best windy sites, upward movements of market determined tariffs
for onshore wind energy in future expected
• Absence of any obstruction in sea offers much better quality of wind & its conversion to
electrical energy.
• Offshore wind turbines are much larger in size (in range of 5 to 14 MW per turbine) as
against 2-3.5 MW of an onshore wind turbine.
• The cost per MW for offshore turbines are higher because of stronger structures and
foundations needed in marine environment, the desirable tariffs can be achieved on
account of higher efficiencies of these turbines.
• Indian coastline of about 7600 km and Good prospects of harnessing offshore wind
energy;

3. 3
National offshore wind energy policy
• National offshore wind energy policy notified on 6th October 2015.

The first 1.0 GW offshore Wind Energy Project
• The first offshore wind energy project of 1.0 GW capacity 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.
• EoI for the first offshore wind project of 1.0 GW capacity off Gujarat coast was
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.

13.  Offshore wind energy potential estimation carried out through satellite data needs to
be validated through actual ground measurements in order to make data bankable.
 Ministry decided to launch a measurement campaign deploying Light Detection and
Ranging (LiDARs) at identified zones off coast of Gujarat and Tamil Nadu.
 One LiDAR was commissioned in Nov’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 report
is published at NIWE’s website.
 The raw data can be accessed from NIWE website.
 As per the report, annual average wind speed at the locations is observed to be
7.52 m/s at 100m hub height.

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.

15. 15
Guidelines for Offshore Wind Power Assessment Studies and
Surveys
• The ‘Guidelinesfor Offshore Wind Power Assessment Studies
and Surveys’was approved and issued by NIWE in September,
2018 to facilitate stakeholders who are interested for carrying
out the study/survey activity for development of offshore wind
energy project.

16. 16
Leasing of the Seabed and Allocation of Blocks
• The offer of blocks will be made through an open ICB process.
• The bidder can be a company, consortium or a Joint Venture.
• NIWE will enter into contract with successful bidder i.e. developer of offshore wind energy power
project and collect lease fee from developer during survey, construction and operation phases.
• Lease will be limited to exploration and exploitation of wind energy in the allocated block(s).
• Broad parameters of contract will include, time frame for completion of installation &
commissioning of wind farm, period of contract, committed Minimum Work Programme (MWP) in
terms of project capacity in allocated block, monitoring & inspection by MNRE/NIWE and
decommissioning plan.
• Lease and area will stand automatically relinquished, if contractor is unable to start commercial
production of wind electricity within a specific time period from date of signing the contract.
• Existing lease holders of seabed for other purposes such as oil & gas exploration and
exploitation, seabed mining etc., interested in installation of offshore wind farm on their existing
lease must route the proposal through NIWE

17. 17
Incentives
• The policy may support the development of offshore wind energy
through fiscal incentives, allowing
o Foreign Direct Investment (FDI) participation
o Public Private Partnership
o international collaborations.
• Fiscal and financial incentives available to onshore wind power projects
may also be made available to offshore wind power projects.
• Besides, Government may promote bundling of power generated from
offshore wind power projects with conventional power subject to
availability of unallocated conventional power to bring down the cost of
power generated resulting in better acceptability.

18. 18
Technology:
• NIWE 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 provided/facilitated by NIWE for Offshore Wind Turbine
Models.
GE:
• Recognizing the offshore wind energy potential, GE has invested more than
$400 million to develop the most powerful offshore wind turbine—an investment
that will also drive down offshore wind farms’ levelized cost of energy (LCOE),
helping make offshore wind energy more competitive for customers.
• Haliade-X platform features offshore wind technology that will help find success
in an increasingly competitive environment. Haliade-X offshore turbine features
a 14 MW, 13 MW or 12 MW capacity, 220-meter rotor, a 107-meter blade, and
digital capabilities.

Establishment of Offshore Wind Energy Projects - 30 GW
By 2030
• Following two models proposed:
Model-1 This approach will be followed for demarcated offshore wind zones for which MNRE/NIWE has
carried out detailed studies/surveys.
Presently, identified Zone B3 (365 Sq.km) off the coast of Gujarat shall be considered in phase-1
of this model.
Model-2 • for wind sites for which detailed studies/surveys have not been carried out.
• off shore wind project developers may select a wind site within Exclusive Economic Zone
(EEZ) and will carry out required studies/surveys with approval of MNRE subject to the
clearances from various ministries/departments.
• MNRE through its implementing agencies will come up with bids for procurement of 2 GW of off-
shore wind power capacities tentatively in the FY 2024-25. Those developers who have carried
out the studies and survey will be allowed to participate in the bidding for development of such
projects.
• Necessary central financial assistance in the form of Viability Gap Funding (VGF) would be
available to achieve a predetermined power tariff for these 2 GW of offshore wind power capacity.
• Developers who have carried out studies and surveys may also decide to develop off shore wind
power projects by themselves for sale of power under bilateral agreement with consumers or for
captive consumption under open access mechanism or on the Power Exchange. However for
such projects central financial assistance will not be available.

VGF for initial phase
• For the initial offshore wind power projects, it is envisaged that VGF (viability
gap funding) or any other financial incentive as decided by GoI may be made
available to bridge the gap between the actual tariff determined through
competitive bidding process and power purchase tariff by the designated entity.

studies/surveys. Gujarat Zone B3 (365 Sq.km)
• MNRE/NIWE have already carried out sufficient studies/ surveys that will
enable developers to bid and commence development of offshore wind
projects.
• Two stage single bid process followed by E-Reverse Auction (e-RA) will
be adopted.
• The biddingwill be carried out by SECI.
• The e-RA will be based either on the tariff or the VGF amount required for
making the project viable with a pre- determined tariff.

26. 26
Model-1
• NIWE carried out following investigations for 365 Sq.km sea bed area (which is
sufficient for a 1.0 GW project capacity) of Zone B3, Gulf of Khambhat, off the
coast of Gujarat:

website.
2. Geophysical investigation and Geotechnical investigation for 3nos of representative boreholes
up to 60m soil depth#.
3. Rapid EIA study#
4. Oceanographic (Wave, Tide & current) for one month#.
#-Data will be shared after the concurrence from MOD (Ministry of Defence)
• This model can be further extended to other zones where NIWE or other
developers who have relinquished capacity, have carried out the necessary studies
& surveys and data is available for sharing subject to project viability and
availability of required CFA.

27. 27
Process under Model-I
• MNRE/designated agency will float a bid for 1GW in the demarcated 365 Sq.km area wherein the
stage-1 clearances have already been accorded.
• MNRE or its designated agency will enter into the ‘Lease Agreement’ for 30 years with the
successful bidders (Offshore Wind Power Developer (OWPD)).
• OWPD shall be required to pay the annual floor lease fee @ Rs 1 lakhs/Sq.km/year for the entire
lease period.
• Successful bidders, submit the detailed project report/ project proposal (DPR) for installation and
commissioning of offshore wind project within maximum period of six months. The DPR shall cover
the survey/ study results and relevant information necessary for obtaining the Stage II clearances.
• MNRE or its designated agency shall enter into the Offshore Wind project 'Concessionaire
Agreement' with the OWPD.
• OWPD shall commission project within four years after from date of “Concessionaire agreement”.
• Reasons beyond the control of the developer, in which case this could be extended but in any case

• Sale of power shall be through SECI / Implementing agency.
• A back to back PSA will be signed with the State DISCOM of Gujarat / Any other State DISCOM.
• Eligible developers shall be able to avail suitable financial incentive such as VGF or any other
financial mechanism as decided by MNRE from time to time.

28. 28
Model-2
• Demarcated offshore zones for which no studies/ surveys have been carried out).
• Following process will be followed for offshore wind power project development under this model:
a. NIWE will facilitate as a single window and coordinate with different authorities for stage-1
and stage-2 clearances.
b. NIWE will issue guidelines along with application format for offshore study/ survey.
c. Developer may select any site/sites for investigations. There will be a minimum gap of one
km between the mast location/site of one developer and the mast location/site of another
developer. The developers will give information's to NIWE about the sites where they
propose to carry out survey/investigation, and they will commence the survey/investigation
only after permission is received from NIWE.
d. Developer may approach NIWE for stage-1 and stage-2 clearances for carrying out study/
survey in the identified area.
e. Based on the stage-1 and stage-2 clearances from various authorities, NIWE will issue an
in-principle approval and consent letter respectively.

29. 29
Model-2
f. After a period of two years (say for e.g. during FY 2024-25), SECI/Implementing Agency will
issue a bid for procurement of 2 GW power from offshore wind power projects along with
necessary financial support from the Ministry.
g. The process of competitive bidding and further project development by the bid winners will be
as per the process detailed out under Model-1.
h. Developers are required to secure projects under competitive bidding or submit proposals for
