context_page_description: As of 2019, Finland has four nuclear reactors in two power plants, all located on the shores of the Baltic Sea, and providing about 30% of the country's electricity. The first reactor came into operation in 1977. A fifth reactor is under construction, scheduled to begin commercial operation in February 2022, and a sixth reactor is planned. If all planned projects are completed, the share of electricity produced by nuclear could double, reaching around 60%.
  Finland's nuclear reactors are among the world's most productive, with an average capacity factor of 95% in the 2010s.
