Background on Project
Dongyuan Tech is a 4 x 50 MW coal plant in Wuda district, Wuhai Prefecture. It was commissioned in 2014, and is owned by Inner Mongolia Dongyuan Technology Co.[4]
Proposed expansion
Inner Mongolia Dongyuan Technology Co. has proposed a 2 x 350 MW expansion of the coal-fired power station for Wuda District. The new units were permitted for construction in September 2015.[5]
2016: Nationwide Restrictions Imposed on Development of Coal-Fired Power Capacity
Due to new restrictions announced during 2016 by the National Energy Administration and the National Development and Reform Commission, further capacity expansions at this location appear to be on hold or cancelled. For details, see China's 2016 Restrictions on Development of Coal-Fired Power Capacity.
With no developments since 2015, the expansion appears to be cancelled.
In 2023, construction progressed with significant investment. In 2024, major construction advanced, with the generator stator placed in August.
In 2024, Unit 5 was reported as nearing completion. Unit 6 boiler preheater beam hoisting was completed.
In 2025, the construction seemed on hold. The steel structure cooling tower was completed in December 2025[6].
