Before 2016 solar energy in Russia was virtually nonexistent, despite its large potential in the country. The first Russian was opened in in November 2010. In 2007 it was estimated that Russia had a total theoretical potential of 2,213 TWh/yr for solar energy, with an economically feasible amount of 101 TWh. The southern parts of Russia, especially the North Caucasus, have the greatest potential for solar energy. In 2010 Russia planned to set up an ove. [pdf]
