Established in 1951, China Electric Power Research Institute (CEPRI), a scientific research institute affiliated to State Grid Corporation of China (State Grid), is committed to doing research on common key application technologies, and basic, forward-looking and strategic studies, promoting consulting services, testing and inspection services and development of technical standards for power grids, and providing technical solutions for State Grid. As an internationally renowned scientific research institution, CEPRI tops the list in China’s electric power sector in terms of comprehensive strength.

Convinced of the need for innovation, CEPRI has made major breakthroughs in core technologies such as ultra-high voltage (UHV), renewable energy, and bulk power grid security, shifting its position from “follower” to “leader” in the development of relevant power grid technology, providing strategic and technical support for the high-quality development of power sector. CEPRI has won 108 national science and technology awards, including two special prizes of National Science and Technology Progress Award; six gold awards, three silver awards, and 21 excellence awards of China Patent Award; 17 China Standards Innovation Contribution Awards, one organization award of China Standards Innovation Contribution Award; and over 1100 provincial and ministerial science and technology awards.

CEPRI owns the UHV DC Test Base, the UHV AC Test Base, the UHV Transmission Tower Test Base, the Tibet High-altitude Test Bases, the State Grid Simulation Center and the State Grid Center of Metrology. It has built advanced test and research system for UHV and bulk power grids with complete functions, strong test capabilities and high technical standards, providing strong support for the construction and safe and stable operation of bulk power grids. It has established the National Wind Power Integration Research and Development (Test) Center and the National Energy Solar Center (NESC), with excellent wind and solar power generation test and inspection capabilities.
