Wind power is now the second least expensive source of electricity, following natural gas. Even though Bangladesh’s wind power potential was surrounded with skepticism in the past, several studies have showcased the country’s dormant prospects for generating wind power. Recently a 60MW wind power plant has started operating at full capacity.
According to the U.S.-based National Renewable Energy Laboratory (NREL), Bangladesh possesses a substantially greater potential for wind power, particularly at a hub height of 140 to 160 meters. In addition to having a 724-kilometer-long coastline, the country also has many small islands, each of which is capable of capturing the powerful winds that are generated in the country’s northeastern region, particularly during the winter season. Regions such as the Bay of Bengal, Kuakata, Sandwip, and St. Martin – have the highest potential for producing electricity from wind power.

5.5 - 9.5m/s
In Chittagong region
According to a study by the Local Government Engineering Department, the annual wind speed in Kuakata’s coastal belt ranges between 2.96 meters per second and 4.54 meters per second. According to statements from power officials, several regions of the country, particularly Chittagong, have consistent wind speeds ranging from 5.5 to 9.5 meters per second at an elevation of 20 meters above ground level for a significant portion of the year.
As Bangladesh navigates its way through the global energy crisis, largely (but not entirely) caused by Russian invasion of Ukraine and OPEC’s decision to slam oil production, renewable energy sources, especially wind, will be pivotal in diversifying the country’s energy mix and ensuring energy security. Construction of both onshore and offshore wind power plants will not only ameliorate the sufferings of energy poor off-grid communities but also add an extra supply of power to the national grid. Additionally, the offshore wind farm projects will allow Bangladesh to maximize the utilization of its coastal resources while furthering the progress of a ‘blue economy’.
5% of total consumption
By 2015
10% of total consumption
By 2020
On the other hand, in order to achieve SDGs, Bangladesh is required to generate 12% of its total energy supply from renewable sources, which is currently only 2%. Previously the government targeted to generate 5% of the country’s total energy demand from renewable sources by 2015 and 10% by 2020, both of which were not realized within the targeted period.
Moreover, finance for energy sustainability projects is comparatively easier to achieve given that the LDC graduation of Bangladesh will make the country ineligible for many other forms of concessional loans. Given the necessity of attracting FDIs in Bangladesh on its way to progress, investing on energy sustainability can prove to be a boon for the economy in the longer run.

Bangladesh has established a goal to produce a total of 5 GW of onshore and offshore wind power within the next ten years, commencing in 2022.
Another National Solar Energy Roadmap 2021-2041 is underway as a long term goal for achieving renewable energy goals in the long run and creating them. According to the draft roadmap, Bangladesh can generate 20000 MW renewable energy by 2041.
Wind Resource Assessment
According to Nasrul Hamid, the Minister of State for Electricity and Mineral Resources, wind mapping operations have been conducted in 9 locations across the country to assess the viability of wind power. These activities involved the collection of wind flow data for the purpose of verification.
In March 2022, the Ministry of Power, Energy, and Mineral Resources of Bangladesh granted a contract to Blix, in a joint venture with Italian consultant CESI and local business Synotech, to perform a pre-feasibility and thorough feasibility study on the establishment of an offshore wind farm. These studies were to be carried out in order to determine whether or not it would be possible to build such a farm.
Encouraging Public-Private Partnership and Attracting Investment
The Government of Bangladesh (GoB) has actively encouraged private entities, especially foreign companies, to invest in wind power projects in Bangladesh to facilitate the transition of Bangladesh to wind power.

Annual Reduction in Emissions
When fully operational, the project is anticipated to have the capacity to generate 145,600 megawatts of power annually. It is estimated that this measure will cut annual emissions by 109,200 tons of carbon dioxide (CO2), 25.15 tons of sulfur dioxide (SO2), and 50.69 tons of nitric oxide (NO). Additionally, it will cut annual coal usage by 44,600 tons.
Initiated in March 2022 with a total cost of $116.51 million, the project has been spearheaded by US-DK Green Energy BD Ltd, a private entity, with financial backing from the Chinese company SPIC Wuling Power Corporation.
According to sources from the Cox’s Bazar Bangladesh Power Development Board (BPDP), the plant is capable of producing enough electricity to supply the town of Cox’s Bazar and the areas immediately surrounding it, which demand an average of 40 megawatts of power each day, which can supply 10,000 households with electricity.
Because of the plant’s wind turbines’ long blades, people refer to it as the “Pankha”, which is a Bangla word meaning a fan.
In the Pipeline
According to the Power Division, the government plans to install 12 wind power plants across the nation. These power plants are anticipated to contribute more than 500 MW of additional electricity to the national grid. There are currently three other wind power projects in the districts of Sirajganj, Bagerhat, and Chuadanga that will be completed by the following year in addition to the 60 MW project that is currently in operation.

After the completion of the construction of an embankment at the site of the Matarbari coal-based power station, it is likely that a wind power project with a capacity of 100 MW will be built in Maheshkhali, which is located in Cox’s Bazar. It is anticipated that it will be commissioned toward the end of 2023.
The implementation of the Payra 50 MW Wind Power Plant is planned to take place in the vicinity of Payra, Patuakhali, specifically in the area surrounding the Payra 1320 MW Thermal Power Plant. The wind power facility is anticipated to commence commercial operation in December 2023, with an estimated capacity to provide 50 MW of electricity to the national grid.
Recommendations
Reducing Costs and Navigating Land Scarcity
The cost of installing wind power capacity in the country can be reduced by undertaking some country specific cost-reduction strategies.
Crop Cultivation in Wind Farms
As an agrarian economy, most of the lands of Bangladesh are flat and arable. However, arable land is becoming more scarce due to the increasing population. Thus, it’s extremely difficult to acquire land for any other purpose than agriculture. However, it’s easier to cultivate crops on a wind farm. Researchers from Iowa State University have discovered that wind turbines have a positive effect on corn crop cultivation. Takle and his team showed that the wind turbine pumps the air downward, which helps crops absorb more carbon dioxide, which boosts photosynthesis. The turbulent air due to the rotation of the turbine also increases plant movements, which increase sunbeam penetration into the crop canopy.
Solar-Wind Hybrid Power Plant
Bangladesh has the highest number of solar home systems in the world. The country has already completed the construction of 10 large scale solar power plant projects. However, large scale solar power plants require huge space which add to the scarcity of cultivable land. A unique solution to this problem is wind-solar hybrid power plants that can harness energy from both wind and solar on the same land. This type of combined power plant reduces the necessity of installing a standalone solar or wind plant facility.
More Extensive Research
To facilitate installing wind power plants, extensive studies on wind power feasibility should be conducted in different parts of Bangladesh to select the best possible options for different scale wind power projects. Location wise wind data collection at different heights is necessary for choosing suitable locations for wind projects.
Financial Incentives
Feed-In Tariffs (FIT), Tax breaks or incentives, subsidies, and other financial incentives should be implemented by the government to encourage investment in wind power.
An income tax exemption of one hundred percent can be claimed for any continuous block of power for the first ten years of an enterprise’s first fifteen years of operation. In some cases, lower customs and excise duties may be applied to specific types of machinery.
Improved Grid Infrastructure
Bangladesh needs to improve its grid infrastructure to accommodate the increasing amount of renewable energy. This could include upgrading transmission lines, building new substations, and improving the overall reliability of the grid.
Capacity Development
The country should largely focus on developing its capacity to manufacture, operate, and maintain such wind power farms. The government should heavily invest in skilling engineers and other professionals to facilitate wind energy in Bangladesh.
Improved Maintenance and Supervision
Many projects suffer from a lack of maintenance and supervision. Every single project should be actively monitored, ensuring proper operation,supervision,n and maintenance.
Developing Wind Policy Frameworks and Guidelines
Bangladesh has developed National Solar Energy Action Plan 2016 and 2021. A National Wind Energy Action Plan could be formulated to further the aim of increasing the share of wind in our energy mix. Additionally, frameworks and guidelines pertinent to the wind energy industry must be developed.
Streamlined Approval Process
The government can reduce the bureaucratic red tape and streamline the approval process for wind power projects to make it easier for private companies or developers to get approval for their projects. This may reduce the time and cost of developing wind power projects in the country.
