Offshore wind energy Development in India, MNRE, Government of India

  1. 1. Offshore wind energy Development in India 1
  2. 2. Introduction • At the recently concluded CoP26, Hon’ble Prime Minister’s introduced five nectar elements (Panchamrit) towards contribution to climate action. One of the key element of Panchamrit is to achieve electric cumulative installed capacity 500 GW from non-fossil based capacity by 2030. • GOI has set a target of 30 GW of offshore wind installations by 2030 • Preliminary wind resource estimation based on Mesoscale model suggested potential of 70 GW of offshore wind off the coast of Gujarat and Tamil Nadu in the demarcated area . • The ‘Offshore Wind Policy’ outlining the basic framework was issued earlier in October, 2015. • The Guidelines for Offshore Wind Power Studies and Surveys for carrying out offshore study/survey were issued in September 2018. • Now, A strategy/roadmap has been prepared to work towards achieving the set target which was discussed with stakeholders under the chairmanship of Hon’ble minister. 2
  3. 3. Assuming 4.5MW /Sq. km of seabed area, 35-40 GW of Installable potential is estimated in Gujarat • 05 offshore zones (Zone A-B-D-E-F) identified off Gujarat Coast. • NIWE carried out studies/surveys for 370 sq. km sea bed area in zone B: (i) Wind Resource assessment (through LIDAR) (Average wind speed – 7.5 m/s) (ii) Geophysical and Geotechnical investigation (iii) Rapid Environment Impact Assessment (EIA) (iv) Oceanographic (Wave, Tide & current) study (v) Marine Spatial Planning (MSP) under progress. • This site will be considered for 1st phase of offshore wind development. Identified Offshore sites (Gujarat)
  4. 4. Assuming 4.5MW /Sq. km of seabed area, 25-30 GW of Installable potential is estimated in Tamil Nadu 07 offshore zones (Zone A-G) identified off Tamil Nadu Coast. Preliminary Assessment shows high annual average wind speeds in the range of 9 - 10.5 m/s. Detailed offshore measurement study/survey not conducted. MNRE intends to invite offshore wind developers for carrying out study/survey in these zones. These zones may come up in 2nd phase of offshore development.
  5. 5. Indicative Auction Trajectory Year Year wise Offshore Wind Bids 2022 1 GW 2023 2 GW 2024 3 GW 2026 4 GW 2027 5 GW 2028 5 GW 2029 5 GW 2030 5 GW Total 30 GW • In 1st phase, offshore bidding for 1 GW capacity off Gujarat coast to be floated by SECI in year 2022. • In 2nd phase, bidding for 2 GW capacity will be floated in year 2023 for projects along Indian coastline by SECI. • The VGF based Competitive bidding will be followed only for 1st and 2nd phase projects. • For 3rd phase of projects, the support in the form of evacuation infrastructure and fiscal incentives such as waiver of transmission charges and Renewable Energy Certificates (REC) multipliers will be explored. 5
  6. 6. Scope of Project Development • Evacuation of power from the offshore pooling delivery point to the onshore meeting/interconnection point by CTU/PGCIL. The cost of evacuation will be socialised. • ‘Lease Agreement’ for 30 years between MNRE or its designated agency and successful bidders. Annual floor lease fee @ Rs 1.0 lakhs/Sq.km/year for entire allocated block shall be paid from the date of allotment to till decommissioning of the project. • Detailed Project Submission within 6 months of Capacity Awarded. • Four Years time period for project Development from the date of signing of “Concessionaire agreement”. Fig: Evacuation Infrastructure Network 6
  7. 7. Offshore Development Models (Model-1) • Demarcated offshore sites where MNRE/NIWE has carried out detailed studies/surveys. • In 1st Phase identified Zone ‘B3’ (370 Sq.km) off the coast of Gujarat. • Under this Model, a two stage single bid process followed by E-Reverse Auction (e-RA) based on the VGF amount will be adopted for awarding capacity. • This model can be further extended to other zones where necessary studies & surveys have been carried out by NIWE. Fig: Offshore Wind site Zone ‘B3’ off Gujarat Coast 7
  8. 8. Offshore Development Models (Model-2) • This model is applicable for all sites along coastline (except sites covered under model-1) • Developer may select any offshore site/sites and carry out study survey. • Bidding Mechanism to be the same as followed under Model-1. • Project Development can happen through either; (i) Bidding (ii) Sale of Power under Open Access regime ( Developer has to submit the DPR within 5 years from the date of consent for study/survey issued by NIWE, which may be extended up to max 6 years on a case to case basis) • Post expiry of the 6 year period, all clearances to the relevant developer shall be withdrawn and the developer shall deposit the study/survey data they have collected with NIWE. • In case of project development under open access, the developer may submit the proposal along with DPR to NIWE. Developer shall directly approach the consumer for sale of power through open access. 8
