Bangladesh's ambition to significantly expand renewable energy by 2030 faces major challenges, with current installed capacity still below 2,000 megawatts (MW) and billions of dollars in investment needed to meet its 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 move 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 set a target of generating 10,000MW of renewable electricity by 2030, while the Renewable Energy Policy 2025 aims to meet at least 20% of national electricity demand from renewable sources 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.
Renewable capacity and targets
Bangladesh's installed renewable energy capacity stood at 1,935.79MW, according to Shahriar Ahmed Chowdhury, director of the Centre for Energy Research at United International University.
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 around 760MW would take Bangladesh's renewable capacity to nearly 5,850MW by 2030.
The Centre for Policy Dialogue (CPD), however, has presented a substantially higher projection. Based on estimated electricity demand of 22,702MW in 2030, it 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 needs a clearly defined national roadmap explaining how its renewable energy targets translate into installed capacity, actual generation and annual project requirements.
Using the reported installed capacity of 1,935.79MW, the country would need an additional 4,209MW to reach the 6,145MW estimate, more than 10,000MW to meet Chowdhury's 12,000MW projection and approximately 16,226MW to reach CPD's 18,162MW estimate.
These comparisons are based on different projections, not separate official government targets. However, they illustrate the scale of the challenge and the need for clarity about what the government intends to achieve by 2030.
Utility-scale and rooftop solar
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. 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 is not the same as operational capacity. 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 offers another route to expanding renewable generation, particularly in a densely populated country where acquiring large areas of land for ground-mounted installations can be difficult.
In June 2025, then chief adviser Muhammad Yunus directed the authorities to pursue a National Rooftop Solar Program, including 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 of installing 3,000MW of rooftop solar capacity by December 2025. However, an earlier analysis reported that only 245MW had been installed between 2008 and mid-2025.
More recent figures attributed to the Sustainable and Renewable Energy Development Authority (SREDA) put rooftop solar capacity at 565.55MW, including net-metered and non-net-metered installations.
The reported breakdown includes 468.38MWp from net-metered rooftop solar systems, with more than 5,190 systems integrated into the national grid, and 93.71MWp from non-net-metered systems, comprising 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 become an important driver of this expansion. For businesses facing electricity costs, rooftop solar can reduce dependence on grid power while improving energy-cost predictability.
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.
Investment and land constraints
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 offers corporate tax exemptions to renewable energy producers for the first 10 years, followed by partial exemptions for another 5 years. The government has also announced the removal of duties on solar technologies and equipment.
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.
For a densely populated country where agricultural land, settlements and infrastructure compete for space, large-scale solar development requires careful site selection and planning.
A streamlined approval process, transparent procurement, bankable power-purchase arrangements and clearer responsibilities among government agencies could reduce uncertainty and help developers move projects from planning to construction.
Grid modernization and energy security
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 depends on changing wind conditions. As the share of variable renewable energy rises, the power system will need 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 program will therefore be critical. Transmission planning must progress alongside renewable project development rather than becoming a bottleneck after 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 figures suggest a substantial gap, although a definitive comparison requires confirmation that the countries use consistent 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.
Experts call for faster implementation
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.
Timely completion of utility-scale projects and prioritizing grid modernization would also be crucial as the share of variable renewable energy increased.
He said the revised target of installing 10,450MW by 2030 would require an average addition of around 2,500MW annually.
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, country director of ActionAid Bangladesh, said an equitable and inclusive energy transition was essential for sustainable development. She warned that Bangladesh's dependence on fossil fuels left its energy security vulnerable to international market volatility.
Professor Dr Eqramul Hoque, vice-chancellor of the Bangladesh University of Engineering and Technology (BUET), highlighted the economic pressure caused by rising international energy prices and called for universities and policymakers to work together to protect the environment and ensure 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 was working to modernize the grid, he said, expressing hope that Bangladesh would achieve the 10,000MW renewable energy target by 2030.
