Bangladesh's ambition to significantly expand renewable energy by 2030 faces major challenges, with current installed capacity remaining below 2,000 megawatts (MW). In addition, billions of dollars in investment are needed to meet the country's targets.
Land shortages, regulatory hurdles, and limitations in the electricity grid continue to slow the transition, highlighting the gap between the country's renewable energy ambitions and its current capacity.
The challenge is becoming increasingly urgent. The country must transition beyond policy announcements and project tenders to deliver operational power plants, encourage households and industries to adopt rooftop solar, attract private investment, and modernize its electricity network.
The government has established a target to generate 10,000MW of renewable electricity by the year 2030. In addition, the Renewable Energy Policy 2025 is designed to ensure that renewable sources meet at least 20% of national electricity demand by 2030, and 30% by 2040.
A revised target of installing 10,450MW by 2030 has raised the stakes further. According to energy analysts, meeting that target will require a significant acceleration in implementation, with thousands of megawatts added every year.
The central question is no longer whether Bangladesh needs a clean-energy transition, but whether its institutions, investors and electricity infrastructure can deliver it at the required pace.
According to Shahriar Ahmed Chowdhury, director of the Centre for Energy Research at United International University, Bangladesh's installed renewable energy capacity stood at 1,935.79MW.
Solar accounts for 1,642.7MW of that capacity, followed by hydropower at 230MW and wind power at 62MW. The figures demonstrate the country's heavy reliance on solar and the relatively limited contribution of other renewable sources.
Chowdhury estimated that Bangladesh would need at least 12,000MW of renewable energy capacity by 2030 and more than 35,000MW by 2040.
The Institute for Energy Economics and Financial Analysis (IEEFA) has estimated that annual additions of approximately 760MW would increase Bangladesh's renewable energy capacity to nearly 5,850MW by the year 2030.
The Centre for Policy Dialogue (CPD) has presented a substantially higher projection. Based on an estimated electricity demand of 22,702MW in 2030, the organization calculated that a 20% renewable share would require 4,540MW of renewable electricity generation.
Accounting for the operating characteristics of renewable power plants, CPD estimated that installed capacity would need to reach approximately 18,162MW to produce that amount of electricity. For 2040, it projected a renewable capacity requirement of 35,713MW.
These estimates are not directly interchangeable. Installed capacity represents the maximum rated output of power plants, whereas generation measures the electricity actually produced over time. Solar and wind output varies according to sunlight, weather and operating conditions.
Nevertheless, the differences highlight a major planning challenge. Bangladesh requires a clearly defined national roadmap explaining how its renewable energy targets translate into installed capacity, actual generation, and annual project requirements.
Based on the reported installed capacity of 1,935.79MW, the country would require an additional 4,209MW to reach the 6,145MW estimate. Furthermore, it would need more than 10,000MW to meet Chowdhury's 12,000MW projection and approximately 16,226MW to reach the CPD's 18,162MW estimate.
These comparisons are based on different projections rather than separate official government targets. However, they illustrate the scale of the challenge and the need for clarity regarding what the government intends to achieve by 2030.
Bangladesh has initiated tenders for 55 ground-mounted solar projects with a combined proposed capacity of 5,238MW, according to information cited in the source material.
A ministry official indicated that implementation could extend until 2028. The official noted that if the projects secure financing, obtain land and regulatory approvals, complete construction and connect to the national grid on schedule, they could make a substantial contribution to renewable generation.
However, proposed capacity does not equal operational capacity, as a tender announcement does not guarantee financing, construction, or timely commissioning. Delays at any stage could reduce the contribution these projects make before the 2030 deadline.
The government needs to establish how many projects have secured financing, how much land is ready, which projects have entered construction and when they are expected to begin commercial operations.
Without publicly available project-level information, it remains difficult to determine how much of the proposed 5,238MW could realistically reach the grid within the available timeframe.
Rooftop solar provides an alternative pathway for increasing renewable energy generation, especially in densely populated nations where securing extensive tracts of land for ground-mounted systems can prove challenging.
In June 2025, then chief adviser Muhammad Yunus directed the authorities to pursue a National Rooftop Solar Program, which included installations on government buildings. The initiative also envisaged private companies installing rooftop systems to help schools, colleges, and madrasas reduce their electricity bills.
The previous interim government had set a target to install 3,000 megawatts of rooftop solar capacity by December 2025. However, an earlier analysis reported that only 245 megawatts had been installed between 2008 and mid-2025.
More recent figures attributed to the Sustainable and Renewable Energy Development Authority (SREDA) place rooftop solar capacity at 565.55 MW, covering both net-metered and non-net-metered installations.
The reported breakdown includes 468.38 megawatts-peak (MWp) from net-metered rooftop solar systems, with more than 5,190 systems integrated into the national grid. Additionally, it features 93.71MWp from non-net-metered systems, which comprise around 468 non-grid-tied or traditional auxiliary installations.
Although the figures indicate progress, rooftop capacity remains considerably below the earlier 3,000MW target. Regularly updated official statistics are needed to establish how quickly the program is expanding and whether household and institutional participation is accelerating.
Industry could emerge as a significant driver of this expansion. For businesses dealing with electricity costs, rooftop solar can decrease dependence on grid power and simultaneously improve the predictability of energy costs.
However, household adoption will depend on the attractiveness of incentives, access to financing, installation costs and practical arrangements for connecting rooftop systems to the grid.
Floating solar installations on suitable water bodies could provide another option where land is scarce. Their development, however, requires careful assessment of potential impacts on fisheries, aquatic ecosystems, navigation and the livelihoods of communities dependent on those water bodies.
Even if Bangladesh identifies enough viable projects, financing could become one of the most significant barriers to the transition.
Imran Karim, former president of the Bangladesh Independent Power Producers' Association, estimated that achieving the 20% renewable energy target by 2030 would require investment of $12 billion to $14 billion.
CPD estimated that achieving a 30% renewable energy share by 2040 could require $35.2 billion to $42.6 billion. The estimates relate to different targets and timeframes and should not be treated as directly comparable.
The Renewable Energy Policy 2025 grants corporate tax exemptions to renewable‑energy producers for the first ten years, followed by partial exemptions for an additional five years. This phased tax relief is intended to encourage investment and development in the sector over a 15‑year horizon.
In a complementary move, the government has removed duties on solar technologies and equipment, lowering the cost of importing and deploying solar‑energy systems.
However, fiscal incentives alone may not be sufficient to attract the required investment. Developers continue to face financing costs, foreign-exchange exposure, land availability, regulatory uncertainty and the commercial terms governing electricity purchases.
Chowdhury identified lengthy approval procedures, the need to secure around 40 permits, a 6-year lock-in period for lead partners, grid constraints and Bangladesh's BB- investment risk rating among the barriers to investment.
Land requirements add another layer of complexity. Chowdhury estimated that ground-mounted solar projects could require around 3 acres per MW, although actual requirements vary according to technology and site conditions. At that rate, a 1,000MW project could require approximately 3,000 acres.
In a densely populated nation where agricultural land, settlements and infrastructure vie for space, large‑scale solar projects must be sited and planned meticulously.
A more efficient approval process, open procurement, financially viable power‑purchase agreements and defined duties for government agencies could lower uncertainty and enable developers to advance projects from planning to construction.
Building renewable power plants is only one part of the transition. Bangladesh must also ensure that its electricity system can absorb, transmit and deliver the power they generate.
Solar output fluctuates with sunlight and weather, while wind generation varies with changing wind conditions.
As the share of variable renewable energy increases, power systems will require stronger transmission networks, battery storage and flexible generation reserves to maintain reliable electricity supplies.
Without adequate infrastructure, newly built renewable plants could face difficulties connecting to the grid or delivering electricity when required.
Chowdhury has emphasized the importance of battery storage and flexible reserves. He has also warned that inconsistencies between energy policy documents could expose investments to the risk of becoming stranded assets.
The government's grid-modernization initiative is critical to ensuring seamless integration of renewable energy. Transmission planning must advance in tandem with renewable project development to prevent delays once power plants are completed.
Regional comparisons indicate considerable room for Bangladesh to expand solar power. Figures attributed to a 2024 International Renewable Energy Agency report and cited at a Waterkeepers Bangladesh event put solar's share of electricity demand at 24% in India, 17.16% in Pakistan, 39.7% in Sri Lanka and 5.6% in Bangladesh.
The data indicate a sizable disparity, but a conclusive comparison hinges on verifying that the countries employ uniform definitions, reporting periods, and measurement methods.
Ultimately, Bangladesh's energy transition will be judged not by the number of policies, targets or tenders announced, but by how much affordable and reliable renewable electricity reaches the national grid.
The transition must also account for environmental safeguards, land-use pressures and the interests of communities whose livelihoods could be affected by new energy infrastructure.
The 2030 target presents an opportunity to diversify the electricity mix and reduce exposure to international fossil-fuel market volatility. However, turning that ambition into reality will require more than an increase in installed capacity. It will demand coordinated action on investment, project delivery, rooftop adoption, storage and grid modernization.
Shafiqul Alam, lead analyst for Bangladesh at IEEFA, told Dhaka Tribune that the 2030 renewable energy target was ambitious but achievable, provided the government accelerated implementation.
He said progress would depend largely on household uptake of rooftop solar incentives, available until February 2027, while industries were likely to move faster as rooftop solar could save them more than Tk7 per kilowatt-hour compared with grid electricity.
As the share of variable renewable energy increases, the timely completion of utility-scale projects and the prioritization of grid modernization will become crucial.
He said the revised target of installing 10,450 MW by 2030 would require an average addition of around 2,500 MW each year.
Earlier, Imran Karim, former president of the Bangladesh Independent Power Producers' Association, estimated that Bangladesh would require $12 billion to $14 billion in investment to achieve its 20% renewable energy target by 2030.
Sharif Jamil, member secretary of DHORA and coordinator of Waterkeepers Bangladesh, called for a clear roadmap, effective measures and strong political commitment to achieve the government's target of generating 10,000MW of renewable electricity by 2030.
Farah Kabir, the country director of ActionAid Bangladesh, stated that an equitable and inclusive energy transition is essential for sustainable development. She warned that Bangladesh's reliance on fossil fuels leaves its energy security vulnerable to volatility in international markets.
Bangladesh University of Engineering and Technology Vice-Chancellor Professor Dr Eqramul Hoque highlighted the economic pressure from rising international energy prices and called for universities and policymakers to collaborate on protecting the environment and ensuring affordable clean energy for future generations.
Power, Energy and Mineral Resources Minister Iqbal Hassan Mahmood said the government aimed to generate 10,000MW of renewable electricity by 2030 and was preparing a special Renewable Energy Law to facilitate decisions and implementation during 2026–2030.
“Due to excessive dependence on fossil fuels, global market volatility and the war in the Middle East have affected us. We have prepared a Special Renewable Energy Law to facilitate decisions and activities between 2026 and 2030 to ensure future energy security,” he said.
The minister said duties on solar technologies and equipment had been removed and that government incentives and affordable electricity-purchasing arrangements were being introduced to encourage rooftop solar installations.
He acknowledged that integrating electricity from nuclear, fossil-fuel and renewable sources remained challenging because the national power grid required further modernization.
The Power Grid Company of Bangladesh is working to modernize the grid, he said, expressing hope that Bangladesh will achieve the 10,000 MW renewable energy target by 2030.
