Ownership Tree

This ownership tree is part of the Global Energy Ownership Tracker, a project of Global Energy Monitor.

Background

Jiangyin Sulong power station is a six-unit coal-fired power plant with a total capacity of 1,215 MW. The plant was completed between 1995 and 2005, and was originally owned by Guodian.[6]

Units 1 & 2 were retired in 2025 as per Jiangsu's 2025 outdated capacity elimination list published in March 2026[7]. Unit 3 was mothballed as per the same list[8].

In February 2025, Phase IV Units 7 & 8 received planning approval[9]. Environmental assessment was announced in March 2025[10]. Major equipment bidding occurred in April 2025[11]. EPC bidding began in May 2025[12]. Approval was granted in June 2025[13], and the project commenced with a ceremony in June 2025[14]. Concrete pouring for main plant occurred in August 2025[15]. Boiler steel placement for Unit 7 happened in October 2025, with chimney foundation pouring in November 2025[16][17].

In May and June 2026, cooling tower foundation work and boiler heating surface hoisting progressed[18][19].

Ownership

On August 28, 2017, China's State-owned Assets Supervision and Administration Commission of the State Council (SASAC) announced that China Guodian Corporation and Shenhua Group will be jointly restructured. Shenhua Group will become China National Energy Investment Group and will absorb China Guodian Corporation. It will be the largest power company in the world by installed capacity, as well as the world's largest coal producer.[20][21] The merger was completed on November 28, 2017.[22]
