This paper deals with the estimation of available wind energy potential in Bangladesh and how it can be utilized. The natural sources of energy are limited. Wind is a very good source of energy in many countries of the world. It is a renewable source of energy that can be used in electricity generation, pumping water and many other sectors. But in our country wind energy extraction is a bit difficult due to low wind speed. In this paper, the available wind energy in Rangamati, Bandarban and Teknaf of our country is calculated both hourly basis. Three stations are analyzed in terms of established parameters like Weibull distribution of wind data, frequency distribution of wind directions over few years using measured data collected from Bangladesh Meteorological Department (BMD). The predictions and calculations of wind potentials are performed for commercial turbine altitudes 50-70 m to overcome the limitations of the weather data obtained by meteorological anemometers at lower heights. This analysis can also show the variation in wind energy in different seasons. It can help us to understand how much energy we have and how much energy can be fruitfully utilized.
Statistical Analysis of Wind Power Potential at Pakshey River Delta Region, Bangladesh
Wind energy is now being used in almost every country of the world as an important and pollution free renewable source of energy. In Bangladesh, research in the field of wind energy began only a few years ago. Wind power potentials of the Pakshey river delta region have been statistically analyzed based on the 10 min duration wind speed data in the river delta region. The hourly and monthly wind speed and wind power density are assessed to have remarkable variations and Weibull distribution function has been derived from the available data with its two parameters identified. First of all the wind data of the river delta region in Bangladesh from January to December, 2006 is to be collected and sorted in sequence in appropriate frequency. The data are further analyzed and converted into several useful parameters, like daily mean wind speed, monthly mean wind speed, and mean annual wind speed. After that, the velocity frequency bar graph, energy bar graph, velocity duration curve, etc. have been plotted and analyzed. Weibull shape factor (K) and scale factor (C) has been calculated and plotted by implying different methods. The wind power potential of this side was found to be encouraging; however, the wind power at different site varies significantly. So, wind energy potential in river delta region and costal region has well prospect for choosing wind power plant in Bangladesh.

Asian Journal on Energy and Environment Wind resource assessment for southern part of Bangladesh
have been assessed to determine the potential for wind power generation. The variations of wind speed with year, season and time of day are discussed for these sites as proper positioning of turbines is important for the wind industry. From five LGED stations it was found that the average annual wind speed values at different heights for the five wind stations vary from 1.73 m/s to 4.17 m/s. The highest average annual wind speed (4.17 m/s) was observed in Kuakata and the lowest value (1.32 m/s) was observed at Khagrachari. Maximum wind power density was in Kuakata (88kW/m 2) at height 30m and minimum in Khagrachari (13kW/m 2) at a height of 10m. The highest potential was found for Kuakata and Kutubdia, whereas Khagrachari and CUET have low potential for wind electricity generation. Weibull parameters, namely c and k, were determined using Weibull distribution which is considered useful and appropriate for wind energy as it is one of the easiest methods used to identify the wind potential of a specific site, since it allows for estimation of the probability density function.

Wind Energy Potential in Bangladesh
Bangladesh is encountering difficulties in supplying energy to maintain its economic growth. Government of Bangladesh is looking for renewable energy sources to meet up the total power demand in this country. The present study aims to assess wind energy potential in Bangladesh as a sustainable solution to overcome the energy crisis. Wind speed at six coastal zones Patenga, Cox's Bazar, Teknaf, Char Fassion, Kuakata and Kutubdia at Bay of Bengal of Bangladesh have been analyzed. A near shore wind farm has been considered at these locations having a coastal line of 574 km. The turbines are spaced 7D apart in the prevailing wind direction, and 3D apart in the perpendicular direction, where D is rotor diameter. This near shore wind farm with an array of 5104 horizontal axis wind turbines with hub height of 100 m and rotor diameter of 75 m with a wind speed of 7 m/sec is capable to generate 1855.25 MW of electrical power. This can mitigate 55.93 per cent of energy shortage in 2016. By developing renewable energy sources it is possible to compensate 11.25 per cent of total power demand by 2020.

Journal of Mechanical Engineering, 2009
The present demand of energy is increasing day by day due to various reasons such as increasing population, the aspiration for improved living standards and general economic and industrial growth. In the wake of the increasing world energy crisis, which mostly affected the least developed countries, the interest in alternative energy resources has been increased considerably. In this regard, wind as a source of energy can hold good prospect for a underdeveloped country like Bangladesh. Besides, utilization of wind energy has been growing rapidly in the whole world due to environmental pollution, consumption of the limited fossil fuels and global warming. Bangladesh has fairly wind energy potential, exploitation of the wind energy is still in the crawling level. In the current study, wind characteristics and wind energy potential of Teknaf, Kutubdia, Sandwip, Kuakata, and Mongla in the Coastal Areas are investigated. The measured wind data were processed as hourly and monthly basis. Weibull probability density functions of the locations are calculated in the light of observed data and Weibull shape parameter and scale parameter are also calculated. The main objective is to find out wind energy potential for the utilization.
Wind Energy Analysis for 3 Prospective Costal Sites of Bangladesh
Wind Energy Resource Mapping (WERM) project for Bangladesh was the first of its kind in the country to make a reliable wind energy database, on the basis of which future wind energy conversion systems (WECS) could be installed without failure. The initiative was taken as a part of fulfilling the objectives of our National Renewable Energy Policy to produce 5% of total generation of electricity from renewable sources by 2015 and 10% by 2020. At present per capita energy consumption in Bangladesh is one of the lowest in the world. As it has limited reserves of conventional fuels, there is no other alternative to improve the situation other than to go for renewable sources. In this study wind speed data for Kuakata, Sitakunda and Kutubdia from January to December, 2006 have been analyzed to determine the potential for wind power generation. The variation of wind speed and direction with year, month and time of the day have been studied for proper selection of wind turbines based on Weibull Parameters. The study recommends considering operating WECS for six months from April to September in which energy densities are 147 W/m 2 , 104 W/m 2 and 89 W/m 2 in Kuakata, Sitakunda and Kutubdia respectively.
The radioactive effect of nuclear power plants in accidental cases as well as carbon emission impact of fossil fuels have forced many countries to explore clean energy sources that are environmentally more suitable. As Bangladesh do not have good prospect in fuel cell, geothermal, tidal or wave resources, wind energy is an influential energy source in accordance with solar and biomass. In this paper, based on a2-parameter Weibull analysis method, wind characteristics and assessment of wind energy potential has been analyzed using the wind speed data of the period 2002 -2011 at 10 m height of Cox’s Bazar, the longest sea-beach located at the southeast of Bangladesh. From the calculation, it has been found that the monthly mean wind speed is ranged from 2.17 m/s in November to 2.90 m/s in April, the monthly values of the Weibull shape parameter (k) is ranged from 4.73 to 9.24, while the value of scale parameter (c) is ranged from 2.50 to 2.98 m/s and the monthly wind power density is ranged from 7.30 to 17.14 W/m 2 . The seasonal mean wind speed has been found to be oscillated between 2.31 and 2.78 m/s, while the wind power density is ranged from 8.48 W/m 2 to 14.29 W/m 2 for autumn and spring, respectively. The results presented in this paper will be helpful to assess the feasibility of installing wind turbin e in the subjected area.

Coupling mesoscale and microscale modeling provided reliable mapping results for the commercially exploitable wind resource and was verified by ground-based wind measurement. The results revealed that, among the selected areas, two sites named Charfashion and Monpura have a promising annual mean wind speed ...
WIND ENERGY IN BANGLADESH: PROSPECTS AND UTILIZATION INITIATIVES
Wind, as we all know, is an important source of renewable energy. Bangladesh being a tropical country does have a lot of wind flow at different seasons of the year. However, there are some windy locations in which wind energy projects could be feasible. In our study, we studied previously collected data on the wind resources available in Bangladesh at present and by analyzing this data, have tried to predict if these wind energy resources are sufficient for applications like wind power generation.
Assessment of Wind Power Potential at the Chittagong Coastline in Bangladesh
A small wind data logger is used to record the wind speed for one year (2015 to 2016) at the Chittagong coastline in Bangladesh. A multi-storied building's rooftop in Chittagong Export Processing Zone (CEPZ) is selected as a wind data collection site. The recorded data is analyzed using Weibull distribution functions. Three statistical methods are used to find and compare the Weibull parameters. Weibull probability density function and cumulative distribution are used to explain the recorded data. The analysis shows the shape factor of the site is 1.8 and the yearly scale factor is 2.2ms-1. The highest values of these parameters are found by calculation in the month of June when the maximum shape factor is 3 and the maximum yearly scale factor is 3.95 ms-1. To estimate yearly energy production three different wind turbine models 'Aventa AV-7', 'Enercon E-33' and 'Enercon E-53' are used and the estimation is done using a mathematical approach. The probable wind power production capacity of this site would be around 5457kWh per year and the energy density of this site would be around 11.54 kWhm-2. This research work may be helpful for the design and planning of any wind power plant at the Chittagong coastline area in Bangladesh.

Wind Power for Electricity Generation in Bangladesh
This paper highlights research related to wind energy in Bangladesh which originated as early as in 1979 in collaboration with Free University of Brussels (FUB), Belgium through contacts with the ministry of Co-operation and Development, Government of Belgium and Bangladesh Embassy in Brussels. Some organizations like GTZ, LGED, BCAS, BUET, and BCSIR have started measuring wind speeds at some typical locations of Bangladesh with modern equipments. The SRE project of LGED, in collaboration with BUET and has taken up a study on titled "Wind Energy Resource Mapping (WERM)". The study has been designed in a more comprehensive way aiming at systematic observation on wind regime in initially 20 different suitable locations including Chittagong Hill Tracts region over a longer period of time. A renewable energy policy entitled "Renewable Energy Policy of Bangladesh" has already been adopted by the Ministry of Power, Energy and Mineral Resources, Government of the People's Republic of Bangladesh. The policy has set up targets for developing renewable energy resources to meet 5% of the total power demand by 2015 and 10% by 2020. For this purpose Bangladesh Power Development Board (BPDB) has installed 50 small wind turbines (the first wind firm in Bangladesh) each having 20 kW capacities, totaling one mega-watt wind battery hydride power plant in Kutubdia Island, in the southern region. The feasibility study of wind power and physical investigation were made on the wind firm. Index Terms-Wind power, Mean wind speed, Light house, Weibull's factors.
Bangladesh has a projected electricity demand of 10283 MW by the end of the year 2015. Despite having huge coastline and relatively large area only 100 MW of that huge demand is projected to come from wind power sources. Bulk of this generation is planned to be deployed in the coastal area and adjacent islands. But there are other places of interest for wind power generation, which could be a good means for solving the huge power crisis in Bangladesh. In this paper, feasibility of different scale of wind power generation in 35 different places is studied in the perspective of Wind Power Density (WPD) and Plant Capacity Factor (PCF) at different turbine heights. Only 5 of those sites attain power class 2 or more at 50m height and 17 of them are projected to achieve a PCF of 20% or greater for micro scale generation. At 120m height only 5 sites are projected to attain a much larger WPD and achieve a power class of 2 or more and remaining 30 places still belong to power class 1. Feasibility of deploying large scale wind turbine at Chittagong and Jessore, medium scale at Khepupara, and small scale at Cox's Bazar and Hatiya is studied. All 5 sites attain a PCF of 26% or more which reinforces the feasibility of deploying different scale of wind turbine at those sites.
