"No, I think not," Butkevičius told the Žinių Radijas radio station on Thursday when asked if the findings of the study would determine the necessity for building a new nuclear power facility in Lithuania.
"It (the study) will only show one more important aspect, which is that if we have a nuclear power plant, if it is built, we should know where we will obtain additional electricity from and through what networks it would be sold to the Baltic countries," he said.
Experts from Sweden's Gothia Power are expected to present preliminary findings of their feasibility study to Lithuanian Energy Minister Jaroslav Neverovič on Thursday.
The study is to be completed on September 30.
In April 2012, Gothia Power signed a contract worth 4.34 million litas (EUR 1.26m) with Lithuania's power transmission system operator Litgrid.
The European Union is providing 50 percent of the funding for the feasibility study and the remaining costs are being equally shared by Lithuanian, Latvian, and Estonian electricity transmission system operators.
