Poland has around 164,800,000,000 m3 of proven natural gas reserves and around 96,380,000 barrels of proven oil reserves. These reserves are exploited by energy supply companies such as PKN Orlen ("the only Polish company listed in the Fortune Global 500"), PGNiG. However, the small amounts of fossil fuels naturally occurring in Poland are insufficient to satisfy the full energy consumption needs of the population and industry.  Consequently, the country is a net importer of oil and natural gas. Therefore, since the second decade of the 21st century, Poland has been strongly developing the so-called North Gate in which the most important components are the Baltic Pipe, the Świnoujście LNG terminal and Floating Storage and Regasification Unit in Port of Gdańsk.
