This would be the second site after the Kudankulam Nuclear Power Plant in Tirunelveli district of Tamil Nadu.
For the new site, there are plans to have new reactors of 1200 MW which is an "evolutionary development" from 1000 MW reactor, Sergey P Orlov, Head of ASE Representation in India, said in a press conference.
"We are expecting the new site to be officially presented by the Indian side to the Russian side and we have been informed that it will happen very soon," he said.
"We have started the exchange with the Indian side about the type of plant we are offering but the choosing of the new site is 100 per cent prerogative of the Indian government and the Indian side."

"They are working on that and as soon as they finish they will make an official presentation of that site to us and we shall study the site together with the Indian specialists," Orlov said.
It should "preferably be on the coastal side" since the VVER reactor is a water-cooled one, Orlov said.
On KKNPP's Unit I, which started its commercial operation in December 2014, he said it was going through its second scheduled shutdown and was expected to resume operation by the "first days of August".
The second unit will undergo a similar process in December this year, he said. It had started its commercial operation in March this year.
The construction work of units 3 and 4 of KKNPP commenced on June 29 with the ceremonial pouring of concrete.
The General Framework Agreement for units 5 and 6 had been signed on June 1.
To a question on localisation of equipment, he said it would happen more in units 4,5 and 6.
When the rest of the units resume commercial operation, they will give a very substantial contribution to the power balance of India, Orlov said.
"It happens everywhere when it comes to nuclear power. The general public not fully understanding the nature of nuclear power of course will be cautions of having the plant next to their village, it is understandable," he said.
"As soon as the first unit started operating on a regular basis, providing so much power, the local population finally understood the benefits of having the plant nearby," he added.
