Sihanoukville CIIDG power station is a 405-megawatt (MW) coal-fired power station in Preah Sihanouk (Sihanoukville) Province, Cambodia.

CCIDG has also proposed the 700 MW Sihanoukville CIIDG power station 2.


The map below shows the location of the plant, near Steung Hav, Steung Hav District, Preah Sihanouk (Sihanoukville) Province. The plant is near the 100 MW Sihanoukville CEL power station, and occupies the same land concession.

Background on Plant

In 2010 Cambodia agreed with China to construct a $362 million, 270 MW coal-fired power plant in Stoeng Hav Industrial Zone, Sihanoukville province. A joint venture between Cambodia International Investment Development Group (CIIDG) and unnamed local and Chinese firms was granted a 33-year concession to build and operate the plant, slated for completion by 2014.[1]

In 2011 it was reported that CIIDG Erdos Hongjun Electric Power Co. had been set up as a China-Cambodia joint venture granted permission by the Royal Government of Cambodia to develop a 7 x 135MW coal-fired power project in Sihanoukville in order to generate electricity that would be supplied to the national grid. The company was offering Cambodians "scholarships" to work on a coal plant in China, in exchange for working on the Sihanoukville plant in Cambodia upon returning.[2]

The US$383 million joint venture project operates under a 33-year build-own-operate (BOO) scheme. Units 1 and 2 of 135 MW each came online in November 2014 and March 2015, respectively. Unit 3 is planned to be put into operation by the end of 2016. Coal is sourced from Indonesia.[3]

In September 2016 it was reported that Unit 3 of the plant would be completed in October 2016.[4] Unit 3 was reported in the testing phase in January 2017, with commercial operation planned for the end of the financial quarter.[5]

In January 2018 it was reported that unit 3 was commissioned in 2017.[6]


As of December 2018 there has been no news on the proposed units 4-7 of the power station, first reported in 2011. The four units either appear to have been deferred or cancelled, or have became one of the following projects:

In September 2016 it was reported that the Royal Group, Cambodia's biggest conglomerate, would be involved in funding future phases of the Sihanoukville plant. The plant was reported to be 700 MW total, potentially reaching 900 MW.[7] It's possible the report was referring to the Royal Group power station, a 500 MW coal plant proposed for Stung Hav district.

In July 2018 it was reported that Cambodia International Investment Development Group (CIIDG) had been given approval to construct a 2 x 350 MW coal plant in Sihanoukville of Steung Hav District, the Sihanoukville CIIDG power station 2.[8]

Special Economic Zone

Since 2008, CIIDG has been building the Sihanoukville Special Economic Zone (SSEZ), the biggest industrial park in the country, through a partnership with China-based conglomerate Jiangsu Taihu Cambodia International Economic Cooperation Investment Co. The 11-square-kilometre special economic zone expects the CIIDG plant’s coal-fired generators to power all of its industrial demands.[3]

Stabbing death during construction

In 2013 it was reported that the Chinese manager on the construction site of a coal-fired power plant in Preah Sihanouk province was stabbed to death. The project was a 405-MW power plant in Stung Hav district by Chinese-Cambodian CIIDG Erdos Hongjun Electric Power Co.[9]
