"Certain calculations are taking place. I believe that by the end of October, we should see concrete estimates, and certain models have even been worked out for discussion in order for it to be held at the level of specialists, rather than at the political level," he told parliament.
"We will definitely not delay this," Butkevičius said when asked by an opposition lawmaker if the government would keep putting off its final decision on the Visaginas project.
The prime minister has said that Lithuania and Estonia have been holding active discussions on the project lately.
"I am glad that perhaps stronger discussions between the Lithuanian and Estonian energy companies have resumed recently," he said.
The Lithuanian government is yet to make its final decision on the construction of a new nuclear power plant in Visaginas, in the eastern part of the country.
A working group appointed by Butkevičius concluded last spring that the nuclear power project, in its current form, was too expensive for Lithuania and that the price of electricity generated at the new facility might be non-competitive.
The authorities then said that the project could only be continued if its terms and conditions were improved through talks with Latvian and Estonian energy companies and Japan's Hitachi.
The government in May instructed Energy Minister Jaroslav Neverovič to hold talks with the regional partners and the strategic investor on new terms and conditions.
