Kao Hin Son power station, also known as the Chachoengsao power station, is a proposed 600-megawatt (MW) coal-fired power station planned for Phanom Sarakham, Thailand.

Background on Plant

In 2008, it was announced that a 600 MW coal-fired power plant project would be constructed in the Khao Hin Son Sub-District, Phanom Sarakham District. Local villagers expressed various concerns and held protests and eventually petitioned the King, citing health concerns over the power station. In October 2013 project sponsor NPS again did not get needed approval documents for the station.[1]

According to the Thailand Power Development Plan for 2012-2030, and 2015-2025, Units 1 and 2 will begin operating in November 2016, and Units 3 and 4 will begin operating in March 2017.[2][3]

In January 2016 the environmental and health impact assessment (EHIA) for the project was rejected by the Thailand Environmental Expert Commission. It was the third time the EHIA was submitted. The sponsor was listed as Double A Company.[4]

In the spring of 2017, Double A Power continued to list a 600 MW coal plant among its future projects.[5] As of December 2017, the tab for "Future Projects" had been deleted from the website, indicating that the company had abandoned the project.[6]

Coal plant to be replaced with gas plant

In April 2017 EGAT said a new 1,300MW gas-fired plant will be installed in the same 8-hectare site of the terminated Kao Hin Son coal plant in Chachoengsao province. The new Bang Pakong Power Plant is scheduled to go into commercial operation in April 2019, and use both domestic and imported gas.[7]
