  1. Bangladesh Md. FazlurRahman Pan Asia Power Services Ltd. Dhaka, Bangladesh

  2. Some Key Statistical Data of Bangladesh • Total Population : 140 Million (170 Million Unofficially) • Total Area : 147,570 square kilometer • Access to Electricity : 47 % (FY 2010) • Electricity Growth : 7.0 % in 2010 • Total Consumer : 11 Million (FY 2010) • Transmission Line : 8000 km • Distribution Line : 2,56,000 km • Distribution Loss : 12 to 15 % • Per Capita Generation : 200 kWh/yr (FY 2010)

  3. Power Generation Scenario of Bangladesh

  4. Mitigation Measures: Non Gas Solution Immediate: 6-12 Months - Rental Plants: 500-1500 MW - Per unit cost: Tk 10 (FO) / Tk 16 (Diesel) Short term: 18-24 Months - Peaking Plants: 800 MW - Per unit cost:Tk 8 Medium term: 4-5 years - Base plants: 4X500 MW Coal - Per unit cost:Tk 3.5

  5. Future Renewable Projects Renewable Energy Policy (2008) - 5 % of total generation by 2015 : 450 MW - 10 % of total generation by 2020 : 1600 MW Hydro: small hydro potential exists; limited scope Wind: At least 200 MW wind by 2013 Solar: Existing Capacity: 15 MW – 20 MW - Need at least 80 – 100 MW by 2013 - Still high cost ; off grid solution; may compete with oil Renewable will help in mitigating balance deficit Without wind energy, it is not possible to meet these targets

  6. Monopoly of Natural Gas in the Power Sector of BD

  7. We Need Diversification

  8. Wind Power Prospects of Bangladesh : Rough and Conservative Estimates Curvature Length of Coastal Belt : 1400km If Only 10km inland from the Coastal Belt is considered If Only 5% Coastal Area is available for WT Installations Available Area will be : 70kmX10km = 700 km2 In 1 km2 20 WTs of 2 – 4 MW Capacity can be installed = 40-80MW Rough and Conservative Potentials: >>20,000MW Only 0.3% Area will be occupied by the WTs Rough Potentials are not Negligible

  9. Geographical and Climatic Similarities with India Same Sea Same Wind Same Monsoon Same Climate Same Terrain 12000(+) MW Installed Capacity Bangladesh 1.9 MW In BD: 1.90 MW BB Side : 6000 MW By 2030: 20000MW

  10. Preliminary Indications : Shape of the Coastal Belt • Speeds of the cyclones are increased • due to this funnel shape. •  Main reason of severe cyclones • Same thing for normal winds • The are very good possibilities of wind • energy • But Met. Data are very poor (2 to 3 m/s). • But measured data are good (>6.50 m/s) V Wind Flow

  11. Measured Wind Data of Some Sites

  12. 1. Too Many and Too Strong Cyclones? • 2. Low Wind or No Wind?

  13. Kutubdia Wind Farm, Bangladesh • Initial Starting Date : 23/12/2007

  14. 1. Tropical Cyclone Akash : 15 May 2007 :: Danger Signal 7 2. Tropical Cyclone Sidr : 15 Nov 2007 :: Danger Signal 10 3. Tropical Cyclone Nargis : 4 May 2008 :: Danger Signal 8 4. Tropical Cyclone Reshmi:28 Oct 2008 : Danger Signal 6 5. Tropical Cyclone Bijli : 18 April 2009 :: Danger Signal 7 6. Tropical Cyclone Aila : 25 May 2009 :: Danger Signal 7 7. Tropical Cyclone Giri: 23 Oct 2010 :: Danger Signal 5 8. More Than 20 Dangerous Local Tornados

  15. Present Condition of the KWPP Pictures taken on 28/03/2011

  16. Main Source of Wind Data Met. Department Met Data are very poor Experts Opinion: No Wind in Bangladesh? Why ?

  17. Met. Data vs Reality

  18. The Met Office is located in an urban built up area.

  19. Terrain Analysis

  20. Monthly Wind Speeds at Kutubdia in 08-09 Wind is Maximum : March to October Peak Demand Season Peak Wind Season

  21. Electrification of the Remote & Isolated Areas • Extension of the Grid is Impossible (in some places) • Extension of the Grid is Expensive • Extension of the Grid is Risky • Extension of the Grid is Time Consuming • There live about 25 to 30% of the Total Population • Many Resources • By 2021 : Electricity for All • With the Present Approach – It is not at all Possible • 1 MW Cost of SPV : US$7 to 10 Million • 1 MW Cost of Wind : Tk. 12 to 15 crores (Grid Q. Power) • With Bottom Up Planning Approach VS Conventional Approach • With Small WTs and Localized Grids of 11KV/440V

  22. Small Wind Turbines (SWT): Most Appropriate for Bangladesh • About 25% of total population is in the remote and isolated areas (>40 Million) • Worst affected by Global Climate Change • Extension of grid is difficult, expensive, risky and vulnerable • SWTs can be transported and installed at any site any time • Grid Quality Power at 220 or 440VAC • Minimum land requirement/occupation • Minimum wastage of Agricultural Land • SWT Electricity Cost: Tk.10 to 15/kWh • SPV Electricity Cost: >Tk. 50/kWh

  23. MagLev Wind Turbines : A New Revolution

  24. MagLev Wind Turbines : A New Revolution • Low noise, low frictional losses, low vibration • Higher efficiency by 20 to 30% • Decreased frictional losses by 40% • Decreased O&M Costs by 50% • Lower materials requirements and lower prices • Low Cut-in Wind Speed (1 to 2 m/s) • Higher working wind range (1 to 40 m/s) • Longer working life (50 to 100 years) • Suitable for lower wind areas • Suitable for rural electrification and Irrigation • Suitable for Urban Building Roofs • Easy to control and less electronics • Low area occupation

  25. Main Barriers to Wind Energy in Bangladesh • Lack of policy support from the Government • Corruption in the public sector • Mind set of aged bureaucrats/policy makers (big power plants for big money) • Lack of adequate knowledge in the top policy makers • Lack of enough pilots/demo projects on wind energy • Lack of infrastructures for the large wind turbines • Hidden subsidies in the conventional energy sources & artificial lower energy costs from them. • Anti-wind propaganda by Ph. D. holders

  26. Recommendations : 1. To undertake and implement some Dual Purpose (Village Electrification & Irrigation) Pilot Projects in some remote and isolated communities of Bangladesh. 2. To undertake and implement some Pilot Projects with the MagLev Wind Turbines in some tall buildings in Dhaka, Bangladesh. 3. Government should immediately announce the Green Tariffs/Feed-in-Tariffs and other incentives to attract private investment/FDI
