During a visit in Denmark, the president said that Lithuania would not be able to secure enough alternative energy sources within the coming decade.
"There is a sense still to have a nuclear power plant but this decision needs to be made by all political parties because it is a long-term goal. It will take about 10-15 years to build it, which means that three or four governments will be involved," Grybauskaitė told journalists.
"There will be a need to consult again with our people because the consultative referendum was negative," the president added.
The new center-left government of Social Democrat Algirdas Butkevičius has pledged to make a decision on continuation of the Visaginas nuclear power plant project by mid-May.
The majority of Lithuanian voters did not back the project in a non-binding referendum that was held in tandem with general elections on October 14. Some 34.09 percent of those who cast ballots said "yes" to building a nuclear power plant and 62.68 percent said "no". The voter turnout was 52.58 percent.
The previous center-right government projected to build a new 1,350-megawatt nuclear power plant by 2020 to 2022 together with Baltic energy companies and Japan's Hitachi.
