Wenergy Tongling Power Generation Company Limited, a joint venture of Anhui Wenergy Company Limited, which is the listed flagship of Anhui Wenergy Group, and Huainan Mining Group Company Limited, is responsible for the construction and operation of the project. China Power Engineering Consulting Group Corporation served as the engineering, procurement and construction EPC firm for the project. Anhui No. 2 Electric Power Engineering and Construction Company is responsible for the construction and installation of the unit.
According to the nation's policy of replacing smaller, less efficient units with larger ones, the new unit will replace two 125-MW units built in Phase III of the Tongling Power Plant's construction. These two units kicked off construction in November 1987 and were commissioned in 1989 and 1990, respectively.
Prior to the final approval of the Phase VI Expansion, these two units had been shutdown since October 2007. After the commissioning of Unit 5, the two units were dismantled on April 2, 2011. According to the schedule, the new unit will begin commercial operation by the end of this month.
