The two nuclear power units, with a capacity of 1,000MW, are under construction in Fujian province in southeast China.
Under the new agreement, Invensys will provide its Triconex critical control, Foxboro I/A Series distributed control systems and human-machine interface solutions.
Invensys said its solutions will allow the Fuqing Nuclear Power company to achieve control, safety and environmental standards.
Earlier the companies signed the contracts in 2008 and 2010 for the development and implementation of several large-scale safety and non-safety distributed control systems, including fully digitized main control rooms.
Invensys Operations Management president and CEO Sudipta Bhattacharya said that Invensys systems and technology, as well as on-site project management, engineering, system integration, and installation and commissioning services, will help drive control, safety and environmental excellence in these new units.
