Specific information:
1.Before the electric power system reform in 2002, the power supply enterprises directly supplied by the Ministry of Electric Power Industry were all called power supply bureaus. As a local administrative organization, the Provincial Electric Power Industry Bureau has both administrative functions and is responsible for production and sales. Therefore, the Provincial Electric Power Industry Bureau is a public institution integrating government with enterprise. Before the electric power system reform, the Provincial Electric Power Industry Bureau and the Provincial Electric Power Company were two brands.
2. After the power supply reform in 2002, the power supply bureau (power supply company) was essentially an enterprise with no administrative function. After the electric power system reform in 2002, the Ministry of Electric Power Industry was abolished, the State Power Company was divided into five power generation groups and two power grid companies, the Provincial Electric Power Industry Bureau was abolished, and the administrative functions were assigned to the Provincial Economic and Trade Commission. As an enterprise, provincial power companies no longer have administrative functions. The prefecture-level city electric power bureau and county-level power supply bureau were renamed as power supply companies. However, due to China's national conditions and people's acceptance, the name change is not complete, and many places still use the names of Electric Power Bureau and Power Supply Bureau.
3. Since June 2005, all local power supply branches have been completely and perfectly renamed as power supply bureaus.
