Vietnam’s EVN suggests steep payment cuts for clean-energy projects in US$13 billion dispute

[HANOI] Vietnam’s state utility has proposed slashing payments to 173 renewable energy projects by as much as 43 per cent for electricity generated while they were deemed to have fallen short of approval conditions.

The move by Vietnam Electricity (EVN) affects projects with a combined capacity of about 12 gigawatts and are worth roughly US$13 billion; these include assets owned by Singapore’s SP Group and Sembcorp.

This comes as Vietnam seeks to resolve a long-running dispute over eligibility under the country’s earlier feed-in tariff (FiT) regime, under which the state, through EVN, guaranteed fixed and generous tariffs for up to 20 years for qualified solar and wind power plants.

At meetings held in mid-April with investors, EVN outlined a plan to settle payments for projects that began commercial operations and sold power to the state utility under FiT schemes before they had been granted the necessary construction completion acceptance (CCA) certificates, according to minutes of meetings seen by The Business Times.

Instead of receiving the full preferential FiT rates stipulated in their earlier power-purchase agreements already signed with EVN, project owners would be paid a transitional tariff of 1,184.9 dong (S$0.057) per kilowatt-hour for the period between their commercial operation date (COD) and the CCA approval dates.

The proposed tariff marks a steep discount – about 43 per cent lower than the FiT1 rate of 2,086 dong/kWh (applied to those commissioned before Jun 30, 2019), and nearly 28 per cent below the FiT2 rate of 1,644 dong/kWh (applied to those commissioned from Jul 1, 2019, to Dec 31, 2020).

Any difference between payments already made at FiT levels and the lower transitional tariff would be clawed back over time.

Plant owners are to repay the amount to the government in equal monthly instalments over a period capped at the interval between their COD and CCA dates, which could range from several months to more than three years.

Under the proposal, once projects receive CCA approval, payments would revert to the agreed FiT rates for the remainder of the contract term.

An official from one of the foreign power investors hardest hit because of the scale of its affected projects said: “The impact is quite significant. We’re not happy, but have no intention to pursue complaints or litigation.”

Liquidity pressures are forcing pragmatism.

“The dispute has dragged on for too long. We just want to resolve this and focus on other work,” he added, noting that the company needed cash flow to settle outstanding debts, especially since EVN has said it would resume full FiT payments from the CCA approval date onward.

Years-long dispute over FiT eligibility

Between 2017 and 2020, investors rushed to pour billions of dollars into Vietnam’s renewable sector to qualify their projects for FiT incentives.

A 2023 government review later flagged 173 projects for lacking the required CCAs. The findings led EVN to suspend payments for affected projects and raised the risk that FiT rates could be reduced or revoked.

Investors have pointed out that the projects previously met all conditions required for COD recognition under EVN’s own guidelines, and noted that no regulation at the time mandated a CCA before COD approval or allowed retroactive tariff adjustments.

In a letter in November 2025, Singapore’s SP Group and more than 20 foreign power companies urged Hanoi to hold urgent talks, and warned that payment delays tied to the retroactive review had pushed some investors to the brink.

SP Group has two affected projects with a combined capacity of 100 megawatt-peak, according to the letter.

Singapore’s energy giant Sembcorp, though not a signatory, also has several solar farms caught in the dispute. In a response to BT in March 2025, the company said that the issue had no material impact on the company’s earnings.

In March this year, chambers of commerce from the UK, Europe, Japan, South Korea and Thailand also wrote to the Vietnamese government calling for an “effective and amicable” resolution.

They warned that the impasse risked triggering financing defaults and forcing companies to publicly disclose in their financial statements significant losses from their multi-billion-dollar investments in Vietnam’s renewable-energy sector.

No formal resolution from the Vietnamese authorities has been announced so far.

Thomas Jakobsen, managing director of Indochina Energy Partners (IEP), a solar-power producer, investor and developer active in South-east Asia, told BT earlier this year that the previous FiT regime fuelled “too fast” renewable expansion and exposed structural risks by encouraging development beyond official planning targets.

He added: “It was very clear early on that this type of FiT, as seen in many other countries, would end in heartbreak.”

He instead gives his support to Vietnam’s latest direct power purchase agreement (DPPA) mechanism, which is a more sustainable, market-based alternative. “Investors who stayed disciplined during the FiT era are now well positioned to continue investing in Vietnam’s renewable sector through DPPAs to meet the country’s goal.”
