For decades, Laos has been defined by its rivers. The Mekong and its tributaries have powered the country’s economic strategy, feeding a string of hydroelectric dams that earned it a nickname across the region: the “battery of Southeast Asia.” Now the country is looking up, to the ridgelines of its southern and central highlands, where steady winds are drawing a new wave of investment and reshaping the national conversation about what clean power should look like.
The shift is more than a change of fuel. It reflects mounting concern about overreliance on water, rising demand for green electricity among Laos’s neighbours, and a government eager to turn its geography into export revenue.
A country built on hydropower
To understand why wind matters, it helps to understand how heavily Laos leans on water. Hydropower accounts for 70% of total generation in Laos, but concerns about that dependence have driven a shift toward wind. Another source puts the figure even higher, noting that some 81 percent of the electricity consumed in Laos is generated by hydropower projects. The exact share varies by year and measure, but the message is the same: the grid is overwhelmingly tied to rainfall and river flow.
That dependence brings risk. Droughts, changing rainfall patterns and the downstream effects of dam building along the Mekong have made water a more contested and less predictable resource. A power sector that can only draw from rivers is vulnerable in dry years, and vulnerable to criticism from communities and neighbouring countries who share the same waterways.
Exports make the stakes higher. Laos exports approximately 80% of its electricity to neighbouring Thailand and Vietnam, contributing 30% of its export value. Electricity is not a sideline for the Lao economy; it is one of its most important sources of foreign currency. Protecting that business means making it more diverse and more resilient.
Why the buyers want something different
The customers are changing, too. Thailand has set its sights on carbon neutrality by 2050, and Vietnam is making its own push toward decarbonisation. Singapore, which has few options for domestic renewable generation, has also shown interest in buying power from Laos. These buyers increasingly want electricity that is not just cheap but demonstrably clean, and for many of them, wind and solar fit that brief more neatly than new dams do.
For Vientiane, that demand creates both a commercial opportunity and a policy signal. If regional buyers are prepared to pay for variable renewables, Laos can position itself as a supplier of a broader range of clean power rather than a one-technology exporter. The government has also tied its ambitions to climate goals, committing to promote renewable energy and low-carbon investment to achieve carbon neutrality by 2050.
Wind arrives in the capacity mix
The turning point came in 2025. According to GlobalData’s analysis of the Lao power market, the launch of three wind power plants lifted the share of renewables in Laos’s capacity mix from 2.6% in 2024 to 14.1% in 2025. In a single year, wind went from a footnote to the dominant non-hydro source. The same analysis found that onshore wind accounted for nearly 74.3% of total renewable power capacity in 2025, followed by solar PV with a 12.8% share.
GlobalData’s power analyst, Attaurrahman Ojindaram Saibasan, said onshore wind will play a key role in the country’s renewable development. The firm expects the trend to continue: renewable power capacity is forecast to rise to 9.8GW by 2035, a compound annual growth rate of 17.1% over 2025–2035.
It is worth keeping those numbers in perspective. A jump from 2.6% to 14.1% is dramatic, but it starts from a very low base. Hydropower is still expected to anchor the system for years to come. GlobalData itself notes that hydro will continue to play an important role in the electricity generation mix. Wind, in other words, is a complement to Laos’s hydro fleet and not a replacement for it.
The projects behind the numbers
Much of the early momentum comes from a handful of large, export-oriented projects in the south-east of the country. The best known is the Monsoon wind farm, being built in sparsely populated mountains near the Vietnamese border. The Asian Development Bank described the plan as including a 600-megawatt Monsoon Wind project in Xekong and Attapeu provinces that will export energy to Vietnam, as part of 1.6 gigawatts of wind investment planned at the time. Other reporting described the project as drawing USD 840 million in investment, with a capacity of 600 megawatts.
A second, even larger scheme followed. In early 2024, Lao authorities approved a 1,200 MW wind power project, the largest of its kind in Laos to date, with an investment of about 2 billion USD. State media said the wind farm was expected to be operational by early 2026 and would help the country strengthen its position as a reliable regional power exporter.
These projects share a pattern. They are sited in remote highland areas where few people live, financed largely by foreign private capital, and linked to cross-border transmission lines that carry the electricity to Vietnam and potentially beyond. That model fits Laos’s long-standing export-first energy policy, and it helps explain why foreign investors have shown interest even though the domestic market is small.
Where the wind blows strongest
Wind is not evenly distributed across the country. GlobalData notes that the southern region, covering the provinces of Sekong, Attapeu and Champasak, has significant wind energy potential. Earlier policy documents also pointed to the central provinces, suggesting that the high mountainous areas along the Lao-Vietnam border in Khammouane and Savannakhet provinces may be well suited for wind energy production.
How much power these winds could ultimately deliver is still debated. A law firm review of the region noted that detailed assessments were still lacking, and that the Asian Development Bank had cited estimates for potential wind power production of 3,000–3,500 MW in Laos. Lao officials have at times cited a far larger figure. A deputy energy minister told state media the country could produce 10,000–15,000MW of solar power and about 100,000MW of wind power.
The gap between those numbers is enormous, and it is a reminder that “potential” is a slippery word in energy. Theoretical resource estimates, technically feasible capacity and what can actually be built, connected and sold are three very different things. For investors and planners, the more useful question is not how large the wind resource is on paper, but how much of it can be tapped economically given terrain, road access, grid connections and buyer contracts.
Targets: ambitious but modest
Laos’s official targets are cautious compared with the headline potential. According to analysis cited by GlobalData, Laos aims for a 75% share of hydropower and an 11% share of variable renewables, specifically solar and wind, by 2030. Separate reporting says the country plans to add 13GW of hydropower capacity by 2030 and has set a conditional target of 1GW of combined solar and wind capacity and 300MW of biopower.
Two things stand out. First, hydropower is not going anywhere; even under the government’s own plans it is set to remain the backbone of the system. Second, the word “conditional” matters. Laos has indicated that some of its renewable goals depend on support from developed countries. As one GlobalData comment put it, the country has the capacity to speed up renewables development depending on funding support, given the supply security hydropower provides and its status as a net exporter.
That conditionality reflects a practical truth. Wind and solar require grid upgrades, flexible operation of existing dams and large amounts of upfront capital. Laos carries heavy public debt, and many of its power assets are financed through foreign loans and partnerships. Climate finance, concessional lending and private investment will all shape how quickly turbines go up.
A natural partner for hydro
One of the more interesting aspects of Laos’s strategy is how well wind and hydropower can work together. Dams can store water and release it when it is needed, which means they can step in when the wind drops. In principle, a hydro-heavy system is one of the best places to add variable renewables, because the dams act as a giant battery that smooths out the ups and downs.
That could allow Laos to stretch its water resources further. Running wind turbines when the breeze is strong lets reservoirs hold more water for later use, which is useful in dry spells. Analysts have argued that this kind of pairing is a way of using the country’s existing assets to support new ones, rather than building something entirely from scratch.
It is also an argument for the “battery” label to be more than a slogan. If Laos can offer cross-border buyers a mix of hydro, wind and solar, managed together, it can present itself as a flexible, lower-risk supplier rather than one whose output rises and falls with the monsoon.
The China factor
The pace of development will also depend on who builds the turbines. Chinese companies have financed a great deal of Laos’s hydropower infrastructure, but until recently they had little involvement in wind. Nikkei Asia reported that this could change as Chinese turbine makers, after rapid growth at home, look for markets abroad. Toru Nishihama, chief economist at the Dai-ichi Life Research Institute, was quoted as saying there is plenty of room for Chinese firms with deep onshore wind experience to get involved in landlocked Laos.
If that happens, it could lower costs and speed up construction. It could also deepen the country’s economic ties to its northern neighbour at a time when questions about debt and dependence are already part of the national debate. Other investors from Southeast Asia, Europe and Japan will be watching how the contest for projects unfolds.
Challenges on the road ahead
None of this is straightforward. Several obstacles could slow Laos’s wind ambitions:
Grid and transmission. Remote wind farms need long transmission lines to reach customers. Building them is expensive, and cross-border agreements take time to negotiate.
Terrain and logistics. Moving huge turbine components along mountain roads in a landlocked country is a serious engineering and cost challenge.
Financing and debt. With limited public funds, Laos depends on foreign capital. Investors will want stable regulation and reliable payment from buyers.
Environmental and social safeguards. Wind farms generally have a smaller footprint than large dams, but they still affect land use, forests and communities. Good consultation and monitoring will be essential to avoid repeating past controversies.
Policy follow-through. Reviews of Laos’s climate commitments have flagged that some policy areas, including forestry, transportation and renewable energy, were not on track at the time of the assessment. Turning targets into operating plants will require consistent implementation.
What it means for the region
If Laos succeeds, the effects will reach well beyond its borders. Vietnam, which faces rapidly rising electricity demand, gains another source of power. Thailand and Singapore gain more options as they try to decarbonise their imports. And the wider Mekong region gets a case study in how a hydro-dependent country can diversify without abandoning the assets it already has.
For Laos itself, the stakes are economic as well as environmental. A more varied power mix could shield export income from drought, attract new classes of investors and support the government’s broader goal of becoming a regional energy hub. It could also help the country move away from coal-fired generation, a direction GlobalData says Laos is pursuing with a focus on onshore wind and solar PV.
The takeaway
Laos is not abandoning its rivers. But it is clearly learning that a country cannot build its future on a single resource, however abundant it once seemed. With wind farms now feeding into the grid and more large projects in the pipeline, the Lao highlands are becoming a new frontier for Southeast Asian clean energy.
The next few years will test whether the country can match its enthusiasm with execution: securing financing, building the grid, safeguarding communities and ecosystems, and delivering power reliably to customers across the border. If it does, the “battery of Southeast Asia” may end up with a second, windier chapter. If not, the gap between potential and reality, so evident in the debate over how much wind Laos really has, will persist.
