  1. A Developing Power System: Challenges & Prospects (Case study on Bangladesh) Monir Hossain Graduate Student (PhD) Electrical Engineering University of New Orleans

  2. CHINA INDIA INDIA SYLHET RAJSHAHI INDIA DHAKA BARISAL INDIA KHULNA CHITTAGONG Bangladesh at a Glance • Official Name : People’s Republic of Bangladesh • Political System : Parliamentary Democracy • Population : 158 million • Area : 147,570 km2 • Time Zone : GMT+6 Hours • GDP Per Capita : USD 829 (FY 2013) • GDP Growth Rate: 6-7% (High compare to other SARAC countries) • Major Maritime Ports: Chittagong, Mongla • Currency : BDT (1 BDT = USD 0.014) • Major Industries : Textile & RMG, Jute, Pharmaceuticals, Ship breaking 200 miles 500 km 2

  3. Bangladesh Power SystemYear 1972 Infrastructure: Generation: 165MW 132kV Line: 1583 ckt km 66kV Line: 167 ckt. km

  4. Bangladesh GridNetwork Year 2003 Infrastructure: Generation: 3200MW 230kV Line: 1365 ckt. km 132kV Line: 4961 ckt. km 230/132kV SS: 7 (3150 MVA) 132/33kV SS: 63 (5507 MVA)

  5. Bangladesh Power SystemYear 2014 Infrastructure: Generation: 10GW 400kV Line: 54.7 ckt. km 230kV Line: 3038 ckt. km 132kV Line: 6224 ckt. km HVDC Station: 1 (500 MW) 230/132kV SS: 17 (7525 MVA) 132/33kV SS: 103 (11780 MVA)

  6. Historical Energy Net Generation (GWh) in Bangladesh

  7. Present Structure of Power Sector • Apex Institution • Power Division, Ministry of Power, Energy & Mineral Resources (MPEMR) • Regulator • Bangladesh Energy Regulatory Commission (BERC) • Generation •  Bangladesh Power Development Board (BPDB) • Ashuganj Power Station Company Ltd. (APSCL) •  Electricity Generation Company of Bangladesh (EGCB) •  North West Power Generation Company Ltd. (NWPGCL) • Independent Power Producers (IPPs) • Transmission •  Power Grid Company of Bangladesh Ltd (PGCB) • Distribution •  Bangladesh Power Development Board (BPDB) •  Dhaka Power Distribution Company (DPDC) •  Dhaka Electric Supply Company Ltd (DESCO) •  West Zone Power Distribution Company (WZPDC) • Rural Electrification Board (REB) through Rural Co-operatives

  8. Bangladesh’s Power Sector: At a Glance 8

  9. Primary Fuel Supply Options • Gas: Only 16 TCF proven reserve. No significant gas discovery in recent years. Depleting gas reserve restricts gas based generation expansion • Hydro: Present capacity 230 MW. No further significant potential • Coal: Total 3.2 billion ton reserve in 5 mines. Mines are located at dense populated area. • Oil: Depends on importing. • Renewable: Present capacity only 70 MW. High prospect of solar. 9

  10. Present Installed Generation Capacity • Considering 20 % Maintenance and Forced Outage, Available Generation Capacity is about 7500 MW without fuel constraint 10

  11. Fuel Mix: FY-2013 11

  12. Typical Summer Load Curve MW

  13. Typical Winter Load Curve MW

  14. Estimated Future Demand MW 14

  15. Challenges • Huge demand supply gap causes regular load shedding • High growth rate of electricity due to new electrification & industrial growth • Fuel crisisdue to depleting gas reserve • Arranging fund for investment

  16. Scopes & Prospects • Efficiency improvement of existing power plants. • Fuel diversification. • Regional power trading.

  17. Efficiency improvement of existing power plants. Total gas based power plants: 6500MW Average efficiency of gas based power plants: 30% Efficiency of modern CCPP (Gas)= 60% Possible output using same amount of gas= 13000MW

  18. Fuel Diversification Coal: Local Coal + Imported Coal Solar:

  19. Road Map for Coal Power Development K-D-P 6x1000 MW Meghnaghat 2x660MW Chittagong 4x660MW Moheshkhali/Matarbari 4x660MW Railway Khulna 2x660MW Total 14,000MW Coal Center Chittagong Matarbari Sonadia Island : Potential Coal PS : Potential Coal Center : Ocean-going vessel : Transship

  20. Solar Power • Huge potential in solar • Land constraint • Rooftop Solar Panels • Islands for Mega Solar Bangladesh

  21. Regional Power Trade

  22. Hydro Power Potential & Transmission corridor Solar Power • India needs corridor • Nepal & Bhutan has excess potential Huge prospect in solar Main limitation: Land constraint Islands can be identified for solar (2000MW) 60GW 80GW 30GW Bangladesh

  23. Regional Power Exchange: Possibilities 6.5GW 6x6.5GW 1GW 6.5GW 2GW 4-6GW 1GW 1GW

  24. Probable Power Generation:Primary Fuel Sources by 2030

  25. Recommended Strategic Policy • Ensuring Investment Friendly Environment • Efficient use of gas: Simple Cycle to Combined Cycle Conversion • Coal Policy • Deep Sea Port & Coal Centre • Locations Identification for Mega Solar • Friendly Relation with Neighbor’s • Participation on Hydro Power Development Projects (India, Nepal & Bhutan)
