The energy mix of Russia is pretty specific as the country depends highly on conventional energies which account for 87 % of the total energy consumption (~700 MTOE) \cite{statistic}. The most important energy in Russia is natural gas covering 50% of primary energy consumption \cite{eia}. 39% of the primary energy is used for the electricity generation. The installed capacity for electricity generation was 250 GW in 2017. 83% of the installed capacity are thermal or nuclear power plants \cite{rosstat}. Russia is the world’s second-biggest producer of dry natural gas and holds the world’s largest natural gas reserves at 1,668 trillion cubic feet, accounting for about one-quarter of the total demonstrated world reserves. Oil and natural gas export revenues, in fact, account for around 36% of the Russian federal budget (with oil being the primary export and natural gas accounting for around 13% of export revenues) \cite{eia}.
