The Ignalina Nuclear Power Plant is a defunct two-unit RBMK-1500 nuclear power station in Visaginas, Lithuania. It was named for the nearby city of Ignalina. Due to the plant's similarities to the failed Chernobyl Nuclear Power Plant in both reactor design and lack of a robust containment building, Lithuania agreed to close the plant as part of its accession agreement to the European Union. Unit 1 was closed in December 2004. The remaining Unit 2 accounted for 25% of Lithuania's electricity generating capacity and supplied about 70% of Lithuania's electrical demand it was closed on 31 December 2009. Proposals have been made to construct another nuclear power plant at the same site, but the recession of the late 2000s has made financing a replacement power plant a challenging proposition
