Armenia operates one Soviet-designed VVER-440 nuclear unit at Metsamor, which supplies over 40% of the country's energy needs. The EU and Turkey have expressed concern about the continuing operation of the plant. The Armenian energy minister has announced that a US$2 billion feasibility study of a new 1,000 MWe nuclear power plant is to be carried out in cooperation with Russia, the USA and the IAEA. Russia has agreed to build the plant in return for minority ownership of it. Furthermore, the USA has signalled its commitment to help Armenia with preliminary studies.
