An old iteration of this project consisted of a 2 x 300 MW Thermal Power Plant.[1]

In October 2019, it was reported that Cambodia’s state-owned utility firm Electricite du Cambodge signed a 30-year deal to buy coal power from two producers with a combined capacity of 2,400 MW: the 1,800 MW Xekong power station and the Sekong power station, both situated in Laos’ Sekong province. The two plants were to be built in four phases, commissioned from 2024 to 2027.[2]

In October 2020, an official from the Laos Ministry of Mines and Energy (MME) said the construction of a US$400 million power transmission line connecting Cambodia to Laos and the Thai border will start in 2021.[3]

In February 2021, a senior Lao government official said an 1,800 MW coal plant – presumably Xekong – would be built by Phonesack Group Co in the Kaleum district of Sekong (Xekong) province. It was expected to be constructed at a cost of between US$3 billion to US$4 billion and to include the construction of power lines needed to transmit electricity to Cambodia.[4]

In January 2022, PSG Corporation was successful in their tender to become the turnkey contractor for construction works related to Phase I of the project.[5] In June 2022, the company appeared to be hiring a Finance and Accounting Manager for Xekong Power Plant Co. in Kaleum District.[6]


In October 2021, Bridget McIntosh, country director of EnergyLab Cambodia, argued that by damping economic activity and the growth in demand for power, the pandemic had given Phnom Penh the chance to rethink its strategy – particularly plans to import 2.4 GW of coal power from Laos. "If the 2,400MW of coal imported from Laos will struggle to get finance now, wouldn't it be better to invest in solar and wind in Cambodia?" she said. "It would result in billions of dollars of investment, local green jobs and much needed economic stimulus."[7][8]
