India closer to building world's biggest nuclear plant: EDF
Stay tuned with 24 News HD Android App
The company said it had filed a binding offer to supply engineering studies and equipment to build six, third-generation EPR reactors in Jaitapur, western India.
Once finished, the facility would provide 10 gigawatts (GW) of electricity, roughly enough for 70 million households.
Construction is expected to take 15 years, but the site should be able to start generating electricity before its completion.
Finalisation of the contract was expected "in the coming months", an EDF statement said.
Although no financial details have been released, the contract is estimated to be worth in the tens of billions of euros (dollars).
It faced opposition however from local inhabitants since the idea was first floated around 20 years ago, and was delayed after the 2011 nuclear disaster in Fukushima, Japan.
The far-right Shiv Sena party, which is powerful in Maharashtra state where Jaitapur is located, campaigned against the plan, though it has become less vocal recently.
EDF estimates the project will create around 25,000 local jobs during the construction phase, and around 2,700 permanent jobs.
Earthquake risks and the potential impact on local fishing have been cited as key issues.
But Xavier Ursat, head of EDF's nuclear division, told AFP that the company estimates that the site's "geological conditions are excellent and fully comparable to what we find in a country such as France."
