Dongguan Sanlian power station includes two coal-fired power units with capacity above 30 MW, for a total capacity of 285 MW. The plant was completed in 2003 and 2005, and is owned by Dongguan Dongtang Group.[1][2][3]

Sanlian Power Station was founded in 1989. In 2003, Dongguan Dongtang Group, a local sugar refinery enterprise, bought the majority shares of the plant, and turned it into its captive power plant, supplying heat and steam to the sugar refinery process, besides electricity generation. The total capacity of the plant reached 285MW in 2005 after the commission of a 150MW-unit, and later increased to 433MW. In 2010, Dongtang group formed a new company, Dongtang Sanlian Cogen Power Company, with its 2 units, 285MW total capacity. Dongtang Group is still the dominant shareholder of the plant.[4]

The power plant was fined in 2011 by MEPC (Ministry of Environmental Protection of China) for its emission-surveillance data fraud. [5]

All six units at the power plant were retired in 2021. However, instead of waiting to be demolished, apart from Unit 5, the rest of the units were mothballed as emergency backup power.[6][7][8][9]
