Jiangsu Suyuan was originally a three-level enterprise owned by Jiangsu Electric Power Company and its subordinate trade unions, but the enterprise was restructured in 2004. Jiangsu electric power has withdrawn after the restructuring and is already a private enterprise.
In addition, Jiangsu Electric Power belongs to the State Grid, not China Southern Power Grid. However, Suyuan Power is not directly related to any company now.
