The new units will be built by Jiangsu Guoxin Investment Group, which owns and operates the plant in Lianyungang city, near the East China Sea in the Jiangsu province.
The ultra-supercritical technologies offer both higher efficiency and lower emissions than traditional coal-based electricity generation.
Emerson’s Ovation technology has been selected for 40 of 64 1,000MW ultra-supercritical units in China.
The Jiangsu Xinhai facility currently has a generating capacity of 660MW.
The new units, 5 and 6, will replace two old, less-efficient 220MW units that have been decommissioned.
Unit 5 is anticipated to go into commercial operation in late 2012, while unit 6 is scheduled to come online the following year.
Emerson will supply a total of 66 Ovation controllers and 16 workstations.
Ovation technology will monitor and control boilers and turbines supplied by Shanghai Electric Group.
