中国电力企业联合会

Ⅰ.Background of Founding

Early in the late 1970s the electric power operators in China realized the importance of electric reliability and launched a lead-time study on electric reliability which includes:

·Collection of worldwide information concerning electric reliability to broaden up our horizon
·Carrying out pilot projects in specific power enterprises to achieve experience
·To launch technical popularization and staff training on electric reliability management as ways planned

Through successful lead-time efforts ,the Electricity Reliability Management Center (ERMC) under the former Ministry of Water Resources &Electric Power ,the competent authority at that time ,was established to undertake electric reliability management in January 1985. The Center has changed her names several times following the structure changes of power industry in China (from Ministry of Energy to Ministry of Electric power ,then to the State Power Corporation) .The electric reliability management has been formally incorporated in power industry management since 1999 ,with the name of Electric Reliability Management Center under China Electricity Council.
