Russian media reports said the German Siemens concern could win a contract for 49-per-cent participation in the project, as Russia seeks to expand its cooperation with investors in nuclear energy.
The project entails two reactors, each producing 1,150 megawatts, planned to go on stream in 2016 and 1018.
Local media reports said some of the power could be supplied to Germany under the planned Nord Stream pipeline, which would run beneath the Baltic.
The new plant - situated 120 kilometres from the city of Kaliningrad - will comprise WWER modified water pressure reactors, and will compete with Lithuania's planned Ignalina-2 plant, which is due to replace the ageing original Soviet-built Ignalia plant.
