Reliance Infrastructure EPC CEO Arun Gupta said: “This is an extremely prestigious and important project for us. It will give us an opportunity to showcase our expertise in design, construction and project management of power projects.

“We are confident of delivering the project on time and with international quality standards.”

The Kudankulam nuclear power plant is being built in Koodankulam in the Tirunelveli district. It will feature a total of six units, having a combined capacity of 6GW.

Units 1 and 2 of the Kudankulam nuclear plant, each with a power generation capacity of 1,000MW, had previously entered into commercial operations. While the first unit was commissioned in October 2013, the second unit began operations in October 2016.

In March 2015, India had inked an agreement worth Rs330bn ($5.2bn) with Russia to develop the third and fourth 1000MW units, Press Trust of India reported.

The nuclear project features Voda Voda Energo Reactor (VVER) reactors, each with 1GW capacity.
