Vietnam’s state utility, Electricity of Vietnam (EVN), announced this week that it had signed power purchase agreements for 3.2 gigawatts of new solar and wind capacity—enough to power more than 2 million households—just as the country’s annual energy demand surged past 30 gigawatts for the first time. The deals, finalized during the Asian Development Bank’s (ADB) annual meeting in Hanoi, mark the largest single renewable energy expansion in Southeast Asia this year and come as governments across the region scramble to reduce dependence on imported fossil fuels.
The agreements reflect a broader shift in energy policy accelerated by the war in Gaza and the resulting instability in global oil markets. Brent crude prices have hovered above $90 a barrel for six consecutive weeks, the longest streak since 2014, according to data from the International Energy Agency (IEA). In response, at least 12 countries in Asia and the Pacific have either raised renewable energy targets or fast-tracked approvals for new projects since January, the ADB reported.
Fossil Fuel Volatility Drives Policy Shifts
Vietnam’s move follows a year in which its fossil fuel import bill rose by 18%, to $14.3 billion, according to the country’s General Statistics Office. The spike was driven by higher global oil prices and a weaker dong, which lost 4.7% against the U.S. Dollar in 2025. Similar pressures have been felt across the region: the Philippines, which imports 90% of its oil, saw its trade deficit widen by $3.2 billion in the first quarter of this year, even as Thailand’s energy minister warned last month that the country’s fuel subsidies could become “unsustainable” if oil prices remain above $85 a barrel.
“The volatility in fossil fuel markets is no longer a theoretical risk—it’s a budgetary reality,” said ADB President Masatsugu Asakawa in a speech at the Hanoi meeting. “Countries that delay the transition to renewables are exposing themselves to economic shocks that could derail growth and social stability.” The ADB has pledged $10 billion in financing for renewable energy projects in the region through 2030, with Vietnam, Indonesia, and the Philippines identified as priority markets.
Climate Targets and Energy Security Collide
The push for renewables is also being driven by international climate commitments. Vietnam, which pledged under the 2021 Glasgow Climate Pact to reach net-zero emissions by 2050, has struggled to meet its interim targets. The country’s coal-fired power plants, which account for 40% of its electricity generation, have faced repeated delays in upgrades to reduce emissions. The new solar and wind projects are expected to displace 12 million tons of carbon dioxide annually, equivalent to taking 2.6 million cars off the road, according to EVN estimates.
Yet the transition is not without challenges. Vietnam’s grid, designed for centralized coal and hydropower, lacks the infrastructure to handle the intermittent output of solar and wind farms. In 2023, the country curtailed 1.3 terawatt-hours of renewable energy—enough to power 300,000 homes for a year—due to grid constraints, according to a report by the Vietnam Energy Partnership Group. The government has since announced plans to invest $13 billion in grid modernization by 2030, but analysts warn that delays could undermine investor confidence.
Investor Appetite Grows, But Risks Remain
Despite the risks, foreign investment in Vietnam’s renewable sector has surged. In the first quarter of 2026, the country attracted $2.8 billion in commitments for clean energy projects, a 45% increase over the same period last year, according to the Ministry of Planning and Investment. The largest deal—a $1.2 billion wind farm in the southern province of Bạc Liêu—was backed by Denmark’s Ørsted and Japan’s Marubeni, both of which cited Vietnam’s “stable regulatory environment” as a key factor in their decision.
However, not all investors are convinced. The U.S. International Development Finance Corporation (DFC) recently paused a $500 million loan for a solar project in Ninh Thuận province, citing concerns over land acquisition delays and local resistance. “The regulatory framework is improving, but implementation remains uneven,” said a DFC spokesperson in a statement. “We require to see more consistent enforcement before we can scale up our investments.”
Regional Ripple Effects
Vietnam’s renewable energy push is being closely watched by its neighbors. Indonesia, which relies on coal for 60% of its electricity, announced last month that it would accelerate the retirement of 10 gigawatts of coal capacity by 2030, a decade ahead of schedule. The decision followed a $20 billion pledge from a coalition of wealthy nations, including the U.S. And Japan, to fund the country’s just energy transition. Meanwhile, the Philippines has set a target of 35% renewable energy in its power mix by 2030, up from 21% in 2025, though critics argue the goal is still too modest given the country’s vulnerability to oil price shocks.
“The energy transition in Southeast Asia is no longer a question of ‘if’ but ‘how speedy,’” said Lisa Gartner, deputy editor for investigations at The New York Times, who has reported extensively on energy markets in the region. “The real test will be whether governments can balance short-term economic pressures with long-term climate goals—and whether they can do it without leaving communities behind.”
For now, Vietnam’s government has signaled no retreat from its renewable energy targets. In a statement released after the ADB meeting, Prime Minister Phạm Minh Chính called the new power purchase agreements “a critical step toward energy independence and economic resilience.” But with global oil prices still volatile and grid upgrades lagging, the country’s ability to deliver on its promises remains an open question.
