The story
In 1973, the Nanjing Automation Research Institute (Nari Group) was established under the State Grid Corporation of China.
In February 2001, Nari Technology was established as a separate unit under the Nari Group.
On 16 October 2003, Nari held its initial public offering becoming a listed company on the Shanghai Stock Exchange.
In April 2023, Britain's National Grid terminated its contract with Nari's subsidiary, NR Electric and in December 2023, started removing components supplied by it for electric power transmission networks. While no reason was given, it was speculated it was due to cybersecurity concerns after advice was given by the National Cyber Security Centre. NR Electric had worked with National Grid since 2019 and stated the decision would cause "a material loss of income for the business."
