China Electric Power Research Institute (CEPRI), founded in 1951, is a comprehensive research institution and a scientific and technological enterprise affiliated directly to and wholly-owned by the State Grid Corporation of China (SGCC). CEPRI mainly performs the research in the professional fields covering: Planning of Power System; Analysis on the Security and Stability of Power System Operation; Control and Protection of Power System; High Voltage Technology; Power System Automation; Power Electronics and Electricity Saving; Telecommunication and Information; Power Plant and Industry Control; Transmission and Transformation Equipment; New and Renewable Energy Source.

Besides, the main business scope of CEPRI involves: technology R&D; technical consultation and service; technology transfer; and product manufacturing and sales; project contracting; the inspection and test on electric apparatus and meters; and domestic and international trade etc.

CEPRI enjoys its high competence and reputation in science and technology research, equipped with advanced facilities and equipment for testing and experiment. It possesses the National Power Transmission & Distribution Engineering Research and Electricity Saving Center, the largest Power System Simulation Center in Asia, and the National Quality Inspection and Test Center. It has been authorized to award academic degrees of MSc. and PhD in the first level discipline of electrical engineering. It has also set up a centre for postdoctoral studies on electrotechnics as well as master's degree authorized discipline on computer application technology.

CEPRI is an organisation with the attached units of seven standardization committees of electrical power sector including High Voltage Switch Standardization Technology Committee etc., three professional committees including power system professional committee of Chinese Society for Electrical Engineering (CSEE) and Chinese Secretariat of IEC-TC73 Short-Circuit Current Professional Committee. It is the undertaker of Proceedings of the CSEE, a national Chinese core journal collected by EI (Engineering Index). It is also the sponsor of Power System Technology.

CEPRI has nurtured and trained a large number of state-level experts in electric power field, academic leaders, young and mid-aged scientific and technological backbone staff, excellent executive and management staff. Among those, there are one academician of Chinese Academy of Sciences, one academician of Chinese Academy of Engineering, 45 employees with post-doctor and doctor degree, 225 with master degree.

With the great efforts for several decades, CEPRI has obtained remarkable achievement in the theoretical study on key technologies of power system as well as their application and popularization. So far, it has been awarded 1,503 prizes for scientific and technological achievement, including 55 state-level awards, 247 provincial and ministerial awards, 19 SGCC awards. It has obtained 36 national patents, of which one won Chinese Patent Gold Award.

During each crucial stage of the development of China power industry, for instance, in some major construction projects including the first AC 330 kV and the first AC 500 kV power transmission and transformation engineering, the first ±500 kV DC transmission engineering, Three Gorges Project, etc., CEPRI undertook the task of system research and project commissioning, which made a significant contribution to the construction and development of nationwide power grid.

CEPRI has attained the certification of ISO9001 Quality System, for providing the advanced technology, reliable products and perfect services.

Adhering to the principle of "China's electric power, our responsibility", CEPRI will fully develop its advantages in talents and technology resource, promote its close cooperation and wide exchange with business partners from home and abroad, offer products and services of high technology, high quality and high value to power sector, and endeavor to promote the progress of science and technology and the sustainable development of power industry.
