Later, the country carried out electric power reform, abolished the Ministry of Electric Power, and established five power generation enterprises (Huaneng, Huadian, Datang, Guodian and China Power Investment Corporation) and two power grid enterprises (State Grid and China Southern Power Grid), basically realizing the "separation of power plants and networks".
Last year, two companies, Energy Construction and Electric Power Construction, were established, and all the power construction and power equipment maintenance enterprises left over from the power grid enterprises were included, thus realizing the "separation of main and auxiliary".
The next step will continue to deepen and finally realize the "separation of transmission and distribution".
