Counting on Coal: Cambodia’s Fossil Fuel Push Flounders 

Phnom Penh’s plans for coal power expansion survived China’s promise to cut overseas coal investments, but three years on, construction on most of the promised plants have stalled.

The skeletal exterior of one of the newest coal power plants in Cambodia sits silent amongst the surrounding farmland in Oddar Meanchey. On a still afternoon at the very end of June, brick stacks, cement mixers, and truck tires tangled in overgrown weeds show the long lull in construction at the Han Seng plant.

Locals toasting to happy hour down the road from the front gate of the site complained of months of delayed pay for a relative working there as a security guard, adding there was no set date for operations to resume. There was scarcely more information at the nearby Ou Svay commune hall.

‘Maybe the plan changed to complete construction by 2025?’ questioned Roeun Phearin, who was a commune consultant for the plant. ‘The construction is now paused, and we don’t know the reason because it is the internal information of the company.’

Cambodia bet big on coal in 2020. The Kingdom doubled down on fossil fuel that year, with plans to develop three coal power plants to meet the rising electricity demand and, in the process, flip most of Cambodia’s power production from renewable sources to coal. The move bucked the global push for clean energy and dismayed sustainability advocates, but the announced plants are now facing years of delay, raising questions about when, or if, the Kingdom’s latest coal projects will become operation-ready.

When announced, all three plants were attached to China’s infrastructure-focused Belt and Road Initiative. But while China’s 2021 pledge to cut support for coal power abroad killed projects elsewhere in Southeast Asia, Cambodia’s plans appeared to survive the chopping block. Southeast Asia Globe documented the slate of projects across three provinces, as well as Cambodia’s original coal-fired power plant. Of these three sites—which the Cambodian government pledged are its last coal plants—two are in varying stages of inertia. The third is finished and operational.

The move bucked the global push for clean energy and dismayed sustainability advocates.

In deep-rural Oddar Meanchey province, the 265-megawatt, semi-built Han Seng project missed its deadline to begin operations last year. Falling revenue for the Chinese companies in charge pivoted the project to new contractors, who are sticking with coal, but are now investing in solar energy at the same plant.

Meanwhile, near the coast in Koh Kong province, the politically connected Royal Group conglomerate has yet to even break ground on a 700-megawatt power plant initially scheduled to be completed this year. Former residents of the area allege unfair deals and heavy-handed evictions.

Finally, just across the Bay of Kampong Som in Sihanoukville province, Cambodia International Investment Development Group’s (CIIDG) new 700-megawatt coal project appears to be the only one of the three to hit its expected completion targets. Just down the road from it in Steung Hav district is another plant, the 250-megawatt Cambodian Energy Limited (CEL) coal complex, which was the first of its kind in the Kingdom. Local residents fear the effects these power plants could have on their health and environment.

‘This is not good for us,’ said fisherman Hang Dara, who left his job as an electrician at CEL because of health concerns. ‘But it will be much worse for the next generation in this province since they now have even more coal projects.’

Future of fossil fuels

While addressing the U.N. in 2021, and President Xi Jinping pledged that China would stop building coal-fired power projects abroad and step up support for renewables and low-carbon energy in order to stay ‘committed to harmony between man and nature’.

As a major financier and equipper of coal-fired power plants, China’s announcement was hailed as a major step toward achieving the Paris Agreement’s goal to limit global temperature rise by cutting greenhouse gas emissions. The fate of 77 Chinese-backed coal projects around the world that were in varying stages of development before Xi’s pledge were still uncertain as of October 2023, according to the Helsinki-based Centre for Research on Energy and Clean Air (CREA). Almost half of those power plants would be in Southeast Asia.

If these 37 projects in Indonesia, Vietnam, Laos, Cambodia, and the Philippines are operated for their standard 25-to-30-year lifespans, CREA estimates an emissions total of nearly 4,230 million tons of carbon. That’s a little less than the emissions from the U.S. just last year, the centre claimed.

The three coal projects in Cambodia continued after China’s pledge, but 14 power plants were officially cancelled in Indonesia and Vietnam, according to CREA, nixing the production of 15.6 gigawatts of coal-fired energy.

‘With the very dramatic drop of costs for clean energy and the increase of costs for coal, the Cambodian government has the chance to re-evaluate if those coal plants are the best way to meet Cambodia’s power needs,’ said Lauri Myllyvirta, lead analyst at CREA. Cambodia is wading into an especially precarious position, Myllyvirta said, as the country mostly depends on foreign imports of coal. ‘The wild swings in coal prices and global coal markets in the past three years have vividly demonstrated the economic risks of depending on fossil fuels,’ he said, adding that price fluctuations would only ‘become more volatile.’

In 2021, Cambodia imported approximately USD 222 million worth of coal, according to records from the U.N. Comtrade Database processed by Harvard Growth Lab’s Atlas of Economic Complexity. The trade data underlines the role of Indonesia as Cambodia’s largest coal exporter for more than a decade. Nearly 85% of coal imported by Cambodia from 2012 to 2021 came from Indonesia.

Zulfikar Yurnaidi, a senior officer at the ASEAN Centre for Energy in Jakarta, agreed with Myllyvirta that the future of coal is increasingly uncertain. Yurnaidi warned that the international ‘allergy towards coal’ continues to be an unaddressed ASEAN issue.

‘We cannot [get rid of] coal and fossil fuels right away,’ Yurnaidi said. ‘Support from foreign financial institutions is still required. Maybe not to install a dirty power plant, but to help us reach the end goal of reducing emissions by upgrading fossil fuels and investing in renewable energy.’

As coal funding runs dry, international climate finance has risen in Southeast Asia, with millions of dollars going into the ‘just energy’ transitions in Vietnam and Indonesia. After the third Belt and Road Forum in mid-October, Cambodia’s Prime Minister Hun Manet announced Chinese state-owned power companies had offered the Kingdom more than USD 600 million for renewable energy projects.

Despite foreign funding, Yurnaidi asserted that ASEAN’s emphasis on economic growth will continue to require coal while bloc member-states shift to renewable energy sources. ‘ASEAN is a very huge ship with hundreds of millions of people and trillions [of dollars] in GDP,’ Yurnaidi said. ‘With the energy transition, we know this ship needs to take a turn. But we cannot just make a sudden roundabout, because then everyone will fall into the sea.’

Counting on coal

Cambodia’s bet on coal seems to embody that idea.

In the aftermath of COVID-19, Cambodia’s Power Development Master Plan charts the way for the country’s energy expansion from 2022 to 2040 and predicts a steady rise in national demand for energy. The first five years of every ‘energy scenario’ within the plan prioritises the development of Cambodia’s proposed roster of three new coal sites.

At a meeting before the 26th U.N. Climate Change Conference in 2021, also known as COP26, Cambodia’s Minister of Mines and Energy Suy Sem said the country will no longer approve additional coal projects. The years of construction delays facing two of the planned power plants have some experts wary of potential energy shortages. Chea Sophorn, an energy project manager who specialises in renewable developments, stated that shortages would depend on how quickly the Kingdom’s post-COVID economy, and thus energy demand, recovers. 

But with international investors turning away from fossil fuels, Sophorn emphasised that securing support to jump-start the two stalled projects could be difficult.

‘What type of investor will still be able to finance stranded assets like this?’ questioned Sophorn, explaining that without China, there are few to no places for these projects to turn.

Cheap Sour, an official with the Ministry of Mines and Energy, declined to comment and referred the Southeast Asia Globe to the ministry spokesman, Heng Kunleang, who did not respond to attempts at contact. Eung Dipola, the director-general of the ministry’s Department of Minerals, was unavailable for comment.

Construction in Cambodia

In Oddar Meanchey, financial difficulties have already pushed the companies backing the USD 370 million Han Seng power plant to pivot. The state-owned Guodian Kangneng Technology Stock Co. suffered a massive decrease in its net profit for shareholders in the first half of last year, and brought in a new contractor, Huazi International, in September. 

The plan to install 265 megawatts of coal-fired power hasn’t changed, but Huazi has since announced intentions to add 200 megawatts of solar capacity to the site. This is the first time any other type of energy production has been associated with the struggling Han Seng power plant.

Just two kilometres from the semi-constructed project site, the Yun Khean coal mine, which would supposedly one day supply the plant, is operating as usual. However, not everyone is pleased with these developments. Boy Troch, who lives a stone’s throw away from the mine’s slag heaps, believes mining operations have contaminated the groundwater beneath his farm, damaging crops and sickening wildlife.

‘There are a lot of lands affected by the mine, but village and commune chiefs do not care,’ Troch said, pointing at shifting heaps of coal-streaked earth across the road from his land. With his grandchildren by his side, Troch said he feared coal mining would proliferate in his district once the power plant began operations. ‘We are afraid to protest because our voice isn’t heard,’ Troch opined. ‘We are ordinary people. We are more afraid that they will evict us from this land.’

In Koh Kong, stories from evicted residents may validate these fears.

Royal Group, one of the largest investment conglomerates in Cambodia with direct ties to former Prime Minister Hun Sen, received a nearly 170-hectare land concession in 2020 within Botum Sakor National Park for the coal power plant. People living on the site without land titles complained of rough, uncompensated evictions. Former resident Keo Khorn’s home was torn down in 2021 by a government task force. Along with 37 evictees, he petitioned for reparations.

‘We all came together to complain about the company,’ Khorn said. ‘Everyone heard us, the provincial ministries and the national ministries. But no one did anything.’

The project site is currently vacant, but workers are clearing forests around the location. These areas, also within the national park, were given to Royal Group in a second, nearly 10,000-hectare land concession this year.

Thomas Pianka, with Royal Group’s energy division, flatly refused to speak with Southeast Asia Globe reporters. ‘No, I don’t need to talk to you,’ he said before hanging up a call.

Where coal plants are actually operating, residents in Sihanoukville province have different worries. A plant security guard for the older Cambodia Energy Limited site said other workers warned him about health concerns, but the company has never mentioned any risks. The security guard’s deputy village chief, Ly Socheat, said she regularly fields complaints about the smell from the power plant. Socheat went on to say that many of the families in her village have stopped collecting rainwater in fear of contamination from the coal. While Socheat attended several meetings about potential employment opportunities at the power plant, she has also never been informed of any potential health impacts.

Meanwhile, residents have complained of respiratory issues and headaches. Coal-fired power plants have also been linked to cancer: a 2019 study estimated 1.37 million cases of lung cancer around the world will be linked to such plants by 2025. In the waters just off the coast, fisherman Hang Dara recounted why he left his job as an electrician at CEL to instead cast for crabs by the power plant. He believed the plant’s discharged water was heating the bay and harming the environment.

Residents of Thmor Sor in Cambodia’s Koh Kong Province, who were evicted or forced to sell their land to Royal Group for the company’s coal power plant, signed petitions and wrote letters to provincial and national authorities for fairer compensations to no avail. 


Meanwhile, residents have complained of respiratory issues and headaches. Coal- fired power plants have also been linked to cancer.

‘I was very worried about my health,’ said Dara, who explained he had severe headaches and chronic coughs while working at the power station. ‘But now I am very worried about the health of the fish.’

As Dara stands by the bow, his fishing partner Loy Chaeum steers from the stern. As they pass coal-loading docks supplying the two power plants, Chaeum excitedly points out a vulnerable Indo-Pacific humpback dolphin surfacing for air.

‘I don’t see many dolphins now; they don’t like the coal. Like us, they must go farther and farther away to survive,’ said Chaeum, who explained he motored across the bay every morning in search of a better catch. That brings him closer to Koh Kong, where one day, there may be another coal-fired power plant.

‘If they build it, there will be nowhere for them or us to go,’ he said, turning back to land, having lost sight of the dolphin.
