Part 1: Arduous Entrepreneurship (1973-1991)
  • NARI Group Corporation (SGEPRI) originated from Nanjing Automation Research Institute founded in 1973 and Wuhan High Voltage Research Institute founded in 1974.
  • In 1989, NARI Automation Company was founded to further intensify the conversion of scientific research achievements.
Part 2: Independent Innovation (1992-2007)
  • In 1992, the first UHV relay protection device independently developed in China was successfully applied on Tianguang and Tiangui 500kV power lines, which established the leading position of NARI in the domestic relay protection field.
  • Since 1992, the first dam safety automatic monitoring system, first large hydropower station computer monitoring system, first micro-computer hydro turbine speed regulation system, first micro-computer excitation regulation system and water regime forecasting & reservoir dispatching systems independently developed in China have been promoted and applied on large scale, which established the leading position of NARI in domestic power generation and water conservancy automation fields.
  • In 1995, the first dispatching automation system, first substation comprehensive automation system, first distribution automation system and first technical support system for electric power market etc independently developed in China established the leading position of NARI in domestic power grid automation field.
  • In 1996, the Extend Equal Area Criterion (EEAC) invented by Mr. Xue Yusheng won the first prize of National Science and Technology Award, and then the large-scale power grid outage comprehensive defense system developed on the above theoretical basis – WARMAP was widely applied in national, regional and provincial power grids, which established international leading position of NARI in large power grid safety analysis and control field.
  • In 2003, NARI Technology Development Co., Ltd – set up by NARI Group Corporation as the main initiator, was listed on Shanghai Stock Exchange.
  • In 2006, a UHVAC testing base for the SGCC was constructed in place.
Part 3: Leaping Development (2008 - until now)
  • In 2008, the State Grid Nanjing Automation Research Institute and the State Grid Wuhan High Voltage Research Institute were incorporated together to establish the State Grid Electric Power Research Institute.
  • In 2009, complete industrial chains were set in place and thus promoted the development of NARI Group.
  • In 2011, the first flexible DC control protection system in Asia was successfully developed on our own, which achieved the breakthrough in the domestic flexible DC transmission control protection technologies and reached the world-class advanced level in the relevant field.
  • In 2012, NARI Group continued to extend its market to the information communication and power grid monitoring fields.
  • In 2013, in order to fasten the development of amorphous alloy transformer and energy saving services, Shanghai Zhixin Electric Co., Ltd (600517) was successfully founded upon restructuring.
  • In 2013, a smart power grid scientific research industry base (Nanjing) was constructed and then put into operation.
