Wind Power Project by Bangladesh
Power Development Board (BPDB)
Bangladesh Power Development Board (BPDB) implemented the
1000 kWp capacity Wind Battery Hybrid Power Project (WBHPP)
at the Kutubdia
Island( Bay of Bengal) in the Cox’s Bazar District.
1000 kWp Capacity Wind
Battery Hybrid Power Project at Kutubdia Island, Cox's Bazar
District ( Bay of Bengal)
Under this project, total 50 nos. of 20kWp capacity Stand Alone Type Wind Turbines are being installed at Taboler Char areas of the Ali Akber Dell Union Parisahd of Kutubdia Upazilla. The total capacity of all the wind turbines is 1000 kWp( 1 MW). The Wind turbines producing electricity which being stored in battery bank. The entire system tailed as Battery Hybrid Power Plant (WBHPP). This project being installed on turn-key basis at Kutubdia, Cox’s Bazar, Bangladesh.
The wind turbines produce electricity and charges the batteries at battery banks which consisting of 1000 numbers of 200AH with capacity of 12VDC. The stored electrical power from the battery banks being converted to AC ( Alternative Current) by using inverters and distributed to the consumers through overhead power cable. This supply system exactly having 3-phase, On-Grid form and matches with conventional power AC system and loads.
For the conversion of the DC power from the batteries, total 8 nos. of 150KW capacity each inverter has been installed. These inverters give pure sine wave output. These 8 nos. of inverters have been synchronized and paralleled. So the load out put on the system is shared by all these 8 nos. of inverters. The synchronized outputs from all these 8 nos. of inverters are put together in a common bus-bar LT pane. From the common bus-bar the totaled 3-φ out put is supplied to the LT side of a 630KVA, 0.415KV/11KV step-up transformer.
The 11KV output is taken away from the project site area to the Barghop Bazar which is about 8 km away from the project control room. This 11KV power is distributed through out the consumers of the Kutubdia Upazilla Sadar through the 11KV/0.415KV step down transformers and the distribution lines.

Grid Connected Wind Energy Project at Muhuri Dam areas by Bangladesh Power Development Board (BPDB)
BPDB has implemented a pilot project of 0.90 MW capacity of the Grid Connected Wind Energy (GCWE) at the Muhuri Dam Areas in the Feni distrct in 2004. The installation, commissioning and erection works of 4 units of the 225 kWp GCWE turbines at this site had been completed in 2004. This is the first ever Grid Connected Wind Energy project in Bangladesh. The grid connected wind turbines generate electricity at 440V. This is stepped up by the 0.440KV/11KV step-up transformers at then fed into the nearly 11KV distribution lines.
Thus generating electricity from wind in the coastal areas can be transmitted to other regions of the country through the high voltage transmission lines. Very little operation and maintenance will be required during the whole life time of wind turbines and no fuel will be required for generating electricity from wind.

| Pilot project of 0.90 MW capacity of the Grid Connected Wind turbines in the Muhuri Dam areas at Feni District |
BPDB established a Wind Resource Assessment Station (WRAS) at the Moghnama Ghat under Cox's Bazar district is being started. The installation, commissioning, erection, testing etc. works of this WRAS have been completed in December 2003. Wind monitoring by this WRAS has been started in December 2003. So far wind resource data of 5 months of this site have been gathered and these data shows the clear viability of Grid Connected Wind Energy at this site. BPDB is planning for another 0.90 MW pilot project at this site. The pilot for this site is expected to be implemented very soon. Another WRAS installation at Kuakhata is under process to measure the wind potential at that location.
Wind energy installation under renewable Energy Programme (REP):
- Energy Resource : Wind Turbine
- Type of installation : Water pumping wind mill Irrigation
- No of installation : 1
- Capacity of installation : 1X1.0 kWp, 3X1.5 kWp, 1X10 kWp
- Cost of Installation :
- Location of Installation : Patenga (Coastal Area), Chittagong)
- Functional Status : Functioning
- Energy Resource : Wind
- Type of installation : Resource Assessment
- Location of Installation : Coastal Districts
Wind Resource Assessment Station at Feni
BPDB installed a 160 feet tower at the Muhuri Dam site in the Feni district in May 2003. Two high resolution Anemometers were installed on this tower, one Anemometer at 80 feet and the other at 160 feet height. One Wind Vane has been installed at 80 feet height.
The average wind speed, till to date, at the Muhuri Dam areas is 6.50 m/s. For the financial viability of the Grid Connected Wind Turbines, the required annual average wind speed is 6 m/s. So, the wind speeds of the Muhuri Dam areas are encouraging for the grid connected wind energy projects at the project site areas of the Muhuri Dam in the Feni district. The site area is large enough for the larger Wind Energy Projects. The grid is within 0.50 km from the site. The project site is also connected by concrete roads. For all these reasons, the project site area emerges as one of the most suitable areas for grid connected wind farm in Bangladesh.
Studying the pattern of wind blowing over Bangladesh, it has been discovered that the peak windy season of a year coincides with the peak demand for electricity of the country. So, generating electricity from wind with the Grid Connected Wind Turbines, can contribute greatly to cater the increased demand during summer peak season.
Wind Resource Assessment Station at Moghnama Ghat, Cox’s Bazar
BPDB also installed another Wind Resource Assessment Station (WRAS) at the Mognamaghat site in the Cox’s Bazar District. The Installation, commissioning, erection, testing etc. works of this WRAS were completed in December 2003. Wind monitoring by this WRAS started in December 2003. The annual average wind speed at this site is also more than 6.5 m/s.
The site area is large enough for the larger Wind Energy Projects. The grid is within 10 km from the site. The project site is also connected by concrete roads. For all these reasons, the project site area emerges as one of the most suitable areas for grid connected wind farm in Bangladesh.
