To meet its goal of net-zero emissions by 2050, Viet Nam needs to massively increase its renewable energy capacity, particularly solar and wind. This will require substantial investment: the most recent iteration of Vietnam’s Power Development Plan 8 (PDP8) estimates an annual financing need of over $11 billion, much of which will be allocated for renewables. To date, almost all investment in Vietnam’s renewable generation has come from domestic and regional sources. Maintaining the rapid expansion of renewables, however, depends on Vietnam’s ability to unlock international investment.

Viet Nam has done an impressive job tapping into local private investment to rapidly scale up solar from almost nothing in 2017 to more than 16,000 MW in 2022, far exceeding government targets. While it's not yet clear exactly how much solar and wind are included in in the final PDP8, they are clearly set to rise.

The question is how to pay for the large new amounts of renewable energy needed to achieve next-zero emissions by 2050. Most renewable energy projects in Viet Nam have been developed by domestic companies. Data from the Mekong Infrastructure Tracker shows that 58% of renewable energy projects in Viet Nam were developed entirely by Vietnamese companies. Another 27% were developed by a Vietnamese company with an international partner. Only 12% (or 13 projects) were developed without a Vietnamese project partner.

Mekong Infrastructure Tracker data suggest most of the foreign companies sponsoring renewable energy projects in Vietnam come from other countries in Asia, notably Thailand, Japan, and the Philippines. China is largely absent as a project developer or financier in Vietnam, although its companies are heavily involved in neighboring Cambodia and Lao PDR.

The problem is that Vietnamese banks and developers don’t have the financial capacity to meet future investment needs. Achieving net-zero can only be achieved if Vietnam mobilizes international funding. This requires reforms in investment policy. To unlock international support Vietnam needs to address the following regulatory obstacles:

• Unbankable Power Purchase Agreement (PPA) terms. Since 2017, Viet Nam has offered a competitive Feed-in Tariff (FIT) for solar energy projects but Electricity Viet Nam (EVN)’s standard PPA for solar projects allocates too much risk to project developers. EVN can curtail purchases at any moment for an indefinite period of time. The lack of a purchase guarantee is out of line with global best practice and makes the risk profile unpalatable to many international investors. Vietnamese companies have been able to reduce the risk by engaging key political stakeholders in ways that international companies cannot.

• Uncertainty over prices. Vietnam’s 2017 FIT provided a guaranteed price for projects that came online within a specific time frame. But there were two issues: the FIT was adjusted numerous times, often giving developers too little time to qualify for the new FIT, and there were sometimes long gaps without an official FIT. While periodic FIT revisions are understandable given how rapidly Vietnam’s solar market developed, uncertainty over which FIT would apply when a project comes online is a major risk.

• Cumbersome permitting procedures. Registering a new project involves numerous departments from initial project approval to integration into the provincial level plans to land permitting, and so on. The process can be difficult to navigate for international investors without local connections.

• Direct PPAs between private sellers and buyers have been slow to materialise. In 2020, government clarified rooftop solar policies, allowing companies to invest in solar to cut costs and help meet corporate emissions targets. This was an important first step. But rooftop solar alone is insufficient to meet long-term carbon reduction targets, and many companies want to purchase renewable energy directly from outside producers. Despite MOIT announcing plans for a pilot direct PPA scheme in 2019, movement has been slow.

Viet Nam has taken steps to address these issues: in January 2022 the National Assembly adopted Law No. 3 which gives private companies the right to invest in and operate electricity transmission lines. This should alleviate some of the uncertainty and risk involved in connecting renewable energy to the transmission network. The Ministry of Industry and Trade has announced a 2-year pilot direct PPA scheme starting in 2022.

But more needs to be done. The top priority is for the government to issue a revised PPA that is attractive to international investments. There is also a need to ensure that future permitting and pricing policies are transparent, clear, and include longer time horizons to avoid uncertainty.

As electricity demand continues to rise, direct PPAs could play a key role in decarbonizing Vietnam’s industrial sector. Industry is a major emitter of greenhouse gases and many international companies want to green their supply chains and meet their carbon emissions targets, which are often more ambitious than Vietnam’s official targets. Direct PPAs will incentivize these companies to invest in their own renewable energy generation and at the same time reduce demand on the national grid.

This is an important moment for Viet Nam to adopt regulations to attract much greater international financing. The Biden Administration’s Indo-Pacific Strategy prioritizes clean energy, but the U.S. Development Finance Corporation has yet to identify a flagship renewable energy project in Southeast Asia. Post-COP26, the Japan Bank for International Cooperation announced a decarbonization initiative for emerging economies in Southeast Asia as it works toward a net-zero emissions portfolio. Even China, historically a big funder of coal plants, issued guidelines in March 2022 on greening the Belt and Road Initiative by supporting low-carbon projects including renewables and energy storage. If it gets its regulations right, Viet Nam can unlock substantial new funding to power its renewable energy transition.
