Koh Kong power station, also known as the Laem Yai Saen power station, referred to a series of proposals for a coal-fired power station in Koh Kong, Cambodia.

The proposals may have been supplanted by the 700 MW Royal Group's Botum Sakor power station, also planned for Koh Kong.

Background on Plant

Italian-Thai Development proposal

In January 2008, the Cambodia Ministry for Industry, Mines and Energy said the government had approved a plan by Thai in­vestors to conduct a feasibility study for building a US$5 billion coal plant in Koh Kong pro­vince. The plant was intended to produce 3,600 megawatts of electricity for the Thai market, while 200 to 300 mega­watts would be sold for Cam­bodian use. The plant, known as Koh Kong Power Light, was expected to come on-stream by 2014 in the Pouy Yeaysem area on the coast, about 50 km northwest of Koh Kong town. Coal for the plant would have been imported from either Australia or Indonesia. No license had yet been granted to the investors, which included Thailand’s largest construction company Italian-Thai Development PLC, Egco Plc, Ratchaburi Electricity Holding Plc, Datang International (Hong Kong) Ltd, Egat Inter­national, and Sino Thai Resources Development Plc.[1]

Ratch proposal

In March 2012, Ratchaburi Electricity Generating Holding (Ratch) of Thailand entered into a joint-venture agreement with Koh Kong Power to build an 1,830 MW plant in Koh Kong province of southwestern Cambodia, with plans to export the electricity to Thailand.[2]

In 2013, Ratch pulled out of the joint venture saying the company had revised the plan after its analysis indicated that it might have to wait up to 14 years to sell the output to Thailand.[2]

Although it was reported in Khmer Times in June 2014 that Ratch was still pursuing the 1,800MW coal power plant in Koh Kong,[3] the Khmer Times reported in February 2015 that Ratch had backed out of the project.[4]

LYP Group/Thai Samart proposal

In December 2015, Cambodia senator and tycoon Ly Yong Phat, owner of L.Y.P. Group, said he was planning to build a 2,000 MW coal plant in Koh Kong and sell the power to Thailand. According to Phat: "We have already received approval in principal from the government. It will not take too much time to start building the power plant. But, now we need to sign an agreement with our Thai counterpart on buying first. So, when we reach the deal, we will submit all documents to the government to start building our plant."[5] In January 2016, Reuters reported that the company Thai Samart "has long planned to join with partners to build a 2,000 MW coal-fired power plant at Koh Kong, Cambodia. It is negotiating with the Thai state-owned power producer about the electricity tariff."[6]

Interest from EGAT

In June 2017, Thailand's Energy Ministry permanent secretary, Areepong Bhoocha-Oomit, said that Thailand's state-run utility Electricity Generating Authority of Thailand (EGAT) was "now negotiating on building a coal-fired power plant in Koh Kong." The plant would be 2,400 MW. Areepong said that China had expressed interest in Thailand providing transmission services to facilitate power exports from Chinese-backed schemes in Laos and Cambodia to a regional market. While Thailand had transmission connections to Laos, western Malaysia and Singapore, it had no connections to Myanmar, Cambodia, and eastern Malaysia.[7] Plans for a large coal plant in Koh Kong by Thailand's EGAT went back to at least 2008.[8]

In September 2019, Cambodia's Director-General of Eergy, Victor Jona, acknowledged that EGAT had been unable to find a committed buyer at an acceptable price for power from the proposed project. "The investors and the Thai buyers could not agree on the price at which the energy will be sold," Mr Jona said.[9]

With no known progress on the proposals since 2017, the project appears shelved or cancelled.
