Sihanoukville CIIDG power station 2 is a proposed 700-megawatt (MW) coal-fired power station in Preah Sihanouk (Sihanoukville) Province, Cambodia.

CCIDG is also owner of the 405 MW Sihanoukville CIIDG power station.

Background on Plant

In July 2018, it was reported that Cambodia International Investment Development Group (CIIDG) had been given approval to construct a 2 x 300 MW coal plant in Sihanoukville of Steung Hav District. The investment project was under the concession scheme of build-operate-own (BOO) for 35 years. CIIDG was looking for an investment partner for the project and a Chinese firm was reportedly interested. Construction was expected to begin in 2019 and finish by 2023.[1]

In November 2018, it was reported in Chinese media that the 2 x 300 MW subcritical units of the Hunan Chuangyuan power station had been transferred to Cambodia for use in the Sihanoukville CIIDG power station 2.[2] The coal units were forcibly closed in China for violating pollution standards. Transaction records showed the two units were sold for 218 million yuan (US$21.7 million) to Chinese company Kasen International, which specializes in used power plant equipment. The company formed a joint venture with a Cambodian real estate mogul to develop the Steung Hav special economic zone (SEZ) in Cambodia, modeled after a SEZ in Shenzhen, China.[3]

In August 2019, it was reported the project was facing delays, with no construction date set, pushing the expected commissioning to 2023-2024.[4]

In December 2019, a groundbreaking ceremony was held for a 700 MW power station, with operation planned for 2022-2023.[5] That month, Southwest Electric Power Design Institute (SWEPDI), a wholly-owned subsidiary of China Power Engineering, won the contract to build the plant and transmission line.[6]

In June 2020, the environmental and social impact review was completed. CIIDG said a national meeting would be held for final review and approval soon after.[7]

In August 2020, construction of the power station began. Southwest Electric Power Design Institute (SWEPDI) of Energy China Construction and Anhui Power Construction No. 1 Company were the main contractors.[8]

In January 2021, the power station was reportedly 35 per cent complete since breaking ground on December 18, 2019. An article noted the power station was being built on 54.9ha and was expected to be completed by the end of 2022 and online in early 2023.[9]


In April 2020, the Industrial and Commercial Bank of China signed a loan agreement with China Huadian to finance the project.[10] ICBC Asia and ICBC Phnom Penh Branch would collectively provide a US$600 million loan for the first phase of the project.[11]

According to the Council for the Development of Cambodia (CDC) who may have approved the investment (or a related one) in March 2021, the project may be estimated at US$1,283 million.[12]


On August 12, 2013, 173 trainees at the Sihanoukville power plant in the Preah Sihanouk province in Cambodia ended a 5-day protest. The protest ended because the trainees were able to obtain higher wages from their employer at the power plant, the Chinese-Cambodian company CIIDG Erdos Hong-jun Electric Power Co. Buot Chamrong, one of the protestors, said that they “protested to demand that [CIIDG] respect Cambodian labor laws because so far they have implemented Chinese laws to put pressure on us.”[13]

Before the Sihanoukville coal plants were built, local campaigners organized a protest march during Sihanoukville’s 'Sea Festival,' including the Cambodian Human Rights and Development Association (ADHOC). Their motivations included the adverse health effects that would fall upon villagers near Sihanoukville, such as cancer and coal ash inhalation.[14]

In early June 2019, 42 families in the Sihanoukville community formally filed a complaint to the government surrounding the abundance of coal ash from the power plants. The provincial governor then “inspected the site and threatened to close the plant” if it did not clean up its operations.[14]
