Energy in Armenia is mostly from natural gas. Armenia has no proven reserves of oil or natural gas and currently imports most of its gas from Russia. The Iran-Armenia Natural Gas Pipeline has the capacity to equal imports from Russia. Despite a lack of fossil fuel, Armenia has significant domestic electricity generation resources. The Armenian electrical energy sector has had a surplus capacity ever since emerging from a severe post-Soviet crisis in the mid-1990s thanks to the reopening of the nuclear power station at Metsamor. The Metsamor Nuclear Power Plant provides 42.9% of the country's electricity. Armenia has plans to build a new NPP in order to replace the aging Metsamor which was built in 1979. The country also has eleven hydroelectric power plants and has plans to build a geothermal power plant in Syunik. Most of the rest of Armenia's electricity is generated by the natural gas-fired thermal power plants in Yerevan (completed in 2010) and Hrazdan. Upon gaining independence, Armenia signed the European Energy Charter in December 1991, the charter is now known as the Energy Charter Treaty which promotes integration of global energy markets. Armenia is also a partner country of the EU INOGATE energy programme, which has four key topics: enhancing energy security, convergence of member state energy markets on the basis of EU internal energy market principles, supporting sustainable energy development, and attracting investment for energy projects of common and regional interest. Since 2011, Armenia holds observer member status in the EU's Energy Community. History and geopolitics Before the USSR collapsed, oil imports made up about half of Armenia's primary energy supply of 8000 ktoe (compare to 3100 ktoe in 2016). Back then, oil made its way to Armenia via a direct rail link from Armenia-Georgia-Russia, but since the Abkhazia-Georgia border is closed fuel is transported across the Black Sea to Georgia from where it makes its way to Armenia via rail cars. Further restriction to Armenian oil imports represents economic blockade maintained by Azerbaijan to the East, and Turkey to the West. The blockade began shortly after the outbreak of the First Nagorno-Karabakh War and was upheld ever since, despite a cease fire agreement in 1994. Rankings Armenia was ranked 43rd among 125 countries at Energy Trilemma Index in 2018. The index ranks countries on their ability to provide sustainable energy through 3 dimensions: Energy security, Energy equity (accessibility and affordability), Environmental sustainability. Primary
