Background

Daba power station is an eight-unit coal-fired power station of 3,840 MW. It was commissioned in 1991, 2009 and 2019. It is owned by China Huaneng (1-4 units and unit 7-8) and China Datang (5-6 units). Units 5-6 are also known as Daba-3.[1]

Daba-4

China Huaneng was planning to build the Daba-4 coal-fired power plant with a total planned capacity of 1,320 MW in Ningxia Hui Autonomous Region. The company submitted an environmental impact assessment in August 2014.[2][3]

The power station was permitted in 2015,[4] [5]and was reported as under construction in November 2015.[6]

It is planned for operation in 2017.[7]

Nationwide Restrictions Imposed on Development of Coal-Fired Power Capacity

In 2016 China's National Energy Administration issued "scale control" (coal-fired capacity limits) on particular "sending out" locations that feed ultra-high voltage (UHV) long-distance power lines, including Inner Mongolia (Xilingong), Inner Mongolia (Ordos), Shaanxi, Ningxia, and Xinjiang.[8]

As of January 2017, the affected area includes this power station, which may be scaled down as a result. For details, see China's 2016 Restrictions on Development of Coal-Fired Power Capacity.

2017: Plant postponed by government

In July 2017, the NEA released the "Guideline of Supply-Side Reform of the Coal Power Bubble". The Guideline included a draft list which slowed down or halted 185 coal-burning units across 21 provinces, totaling 107 GW. 114 coal units (65 GW) are ordered to slow down the construction progress during 2017 to 2020, and are not allowed to connect to the grid in 2017. In addition, 71 coal units (42 GW) were halted indefinitely for regulation violations. The list partly overlapped with the projects listed in the January NEA letter to 13 provinces.[9]

Huaneng Daba-4 power station Units 1-2 are among the postponed coal-burning units,[9] and also appeared on an updated list of postponements released in September 2017.[10]

For more information, see China's 2016/2017 Restrictions on Development of Coal-Fired Power Capacity.

March 2018: Construction continues

Despite the restrictions applied to the project in July and September of 2017, satellite photos from Planet of 37.9916691, 105.9247833 as well as archival photos from Google Earth show that substantial construction occurred during the period from July 2017 to March 2018, including construction after December 2017.

2018-2019: Plant commissioned

Unit 1 was commissioned in October 2018.[11]

Unit 2 was commissioned in May 2019.[12]
