State Nuclear Power Technology Corporation (Beijing) is serving as the general contractor on the project. China Nuclear Industry Fifth Construction Company Limited (Shanghai, China) is serving as the construction general contractor.

Construction of the nuclear island for Unit 1 kicked off in March 2009. Concrete placing for the conventional island of Unit 1 was completed on January 28, 2011. According to the schedule, Unit 1 of the project is expected to begin commercial operations in November 2013.
