  1. 1. FLOATING SOLAR POWER PLANT BY ABHAY OCEAN INDIA PVT LTD PREPARED BY PROF. V. BHOSALE
  2. 2. Why Floating PV? Ever increasing power demand & depletion of fossil fuels.  Leads to shift our focus to renewable energy sources.  Wind & Hydro RE sources are area specific.  PV can be installed at any place.  Major issue of Solar PV is requirement of land.  But floating solar can be installed on any water bodies.  Floating solar PV results in decrease in cost and will increase amount of generation due to cooling effect of water.
  3. 3. CONCEPT Floating Solar Power is innovative concept in energy technology to meet the needs of our time. Fig: PV floating plant outline
  4. 4. Components of Floating PV  Floating System: A floating body (Structure + Floater) that allows installation of PV module.  Mooring System: This allows to adjust water level fluctuations while maintaining its position.  PV System: PV Generation equipment, similar to electric junction boxes, that are installed on top of floating system.  Underwater Cable: To transfer generated power to substation.
  5. 5. K-water 100 kW  K- water installed 100 kW floating PV on the water surface of Hapcheon water reservoir in 2011.
  6. 6. K- water 500 k W  After successful installation of 100 kW system K- water installed 500 kW PV system on another location at same dam.
  7. 7. Performance Analysis  100 kW PV at Hapcheon is forming 33 degree tilt & its installed capacity is 99.36 kW, composed of 414 240W modules
  8. 8. Performance Analysis  Data is collected from Jan 2012 to Dec 2012. Monthly average generated quantity 10,852 kWh Fig : Performance Analysis graph
  9. 9. Performance Analysis  500 kW PV system forming 33 degree tilt, installed capacity 496.8 kW composed of 2070 240 modules.  Monthly generated Avg. quantity form Oct. 2012 to Mar. 2013 was 55208 kWh.
  10. 10. Comparison Floating PV & Overland PV  Floating solar panels( Blue) having 10.3 % more efficient than overland system.  Fig.: Comparison Graph
  11. 11. Stability of floating sturcture  Graph Floating PV stability against winds.
  12. 12. STATE WISE INSTALLED CAPACITY Ever increasing power demand & depletion of fossil fuels.  Leads to shift our focus to renewable energy sources.  Wind & Hydro RE sources are area specific.  PV can be installed at any place.  Major issue of Solar PV is requirement of land.  But floating solar can be installed on any water bodies.  Floating solar PV results in decrease in cost and will increase amount of generation due to cooling effect of water.
  13. 13. GOVT. OF INDIA INITIATIVES Policy & Regulatory framework ELECTRICITY ACT 2003 : Most transformational & dynamic act till date includes laid guidelines for Renewable energy. SECTION 61(h): While specifying terms and condition for tariff determination the commission shall consider the promotion of generation from renewable energy sources. SECTION 86(1) (e): State commission shall promote generation of Electricity from renewable energy sources. It shall be done by providing grid connectivity & sale of Electricity to anyone. NATIONAL ELECTRICITY POLICY 2005 :  SECTION 6.4 : This section states that in present stage non conventional and conventional energy cannot compete at same similar tariff and hence power shall be procured from non-conventional sources at preferential tariff as determined by appropriate commission.
  14. 14. GOVT. OF INDIA INITIATIVES Policy & Regulatory framework  Amendment of National tariff policy for Solar specific RPO’s.  Solar specific RPO’s – 025 % in 2013 to 3 % by 2022.  REC mechanism .  Encourage state specific solar policies.  State wise RPO orders by Regulators.  Exemption for Environmental clearance for Solar Power Projects.
  15. 15. Jawaharlal Nehru National Solar Mission (JNNSM) Launched by Govt. of India in January 2011. One of the major initiative at global level in promotion of Solar energy technologies. Mission aims to achieve grid tariff parity by 2022. Large scale utilization, rapid diffusion and deployment at a scale which leads to cost reduction. R&D pilot projects and Technology Demonstration.
  16. 16. JNNSM Batch I Bidding Result Summary Average tariff for selected projects was 1216 paisa/kWh which was 32% lower than CERC approved benchmark tariff 1791 paisa/kWh. In a Batch I a total of 204 MW capacity grid connected solar power projects have been commissioned.
  17. 17. Maharashtra Model Solar Policy Maharashtra has reasonably high solar insolation 4-5 kWh/sq. meter with 280-300 clear sunny days. Eastern Maharashtra considered to be most suitable region for solar power projects OBJECTIVE  To generate 1000 MW of Solar energy by 2016. To achieve grid parity by 2016 .  Promotion of R&D and facilitation of technology transfer. Promotion of local manufacturing facilities.
  18. 18. Maharashtra Model Solar Policy Financial outlay of Subsidy Scheme
  19. 19. Maharashtra Model Solar Policy Subsidy under each project will be distributed into three installments by state government.
  20. 20. Maharashtra Model Solar Policy Criteria to avail benefits under the policy  Project developer should not procure any incentives/ subsidy from central government. PPA’s should be singed with MAHADISCOM.  Capacity Utilization Factor of Solar PV should be more than 19% for initial two years of installation.  An audited detailed report and energy generation report should be submitted to MEDA.
  21. 21. Financial Modeling of Solar PV  Capital Cost: Normative Capital cost INR 700 Lakhs/MW for 2014-15 as per MERC. Annual Energy Yield: There are number of factors(e.g. Air pollution, Shading, Soiling, Ambient temperature, Downtime etc.) Which affect annual yield of Solar PV. For 1 MWp Plant annual yield would averaged around 1.4 million kWh units. Yield prediction are assumed for next 25 years. Certified Emission Reductions: As India is non Annex 1 party under UN Clean Development Mechanism (CDM) qualifying solar projects could generate Certified Emission Reductions(CERs)
  22. 22.  Energy Price :  Solar PV Plant under REC mechanism can earn its revenue from selling grey.  In the financial model it is assumed that grey component of energy sold to State discom at MSEDCL.  Operation and Maintenance cost: One of the major benefit of Solar PV plant is less O & M cost as compared to other renewable energy technologies.  Financing Assumptions: General financial assumptions for a project in India as follows  Financial Structure: Equity 30 % and debt 70 % as assumed in MERC tariff order.  Debt repayment is taken over as 10 years. Interest rate on term loan and work capital is taken as 12.87% and 13.37% respectively.
  23. 23. Floating solar PV Indian Context  Great potential for floating PV.  Availability of water bodies and land issues are main accelerators for floating PV solar Panels.  Increased efficiency of Floating PV over Land PV installed will attract more investment due to better returns.  Availability of trained manpower and Govt. Policies have boosts the confidence of investors. Stable floating PV platforms results in minimum operation & maintenance cost.
