Natural gas from Russia has been supplied to Finland for over 45 years. The first contract was signed in 1971, for supplying up to 1.4 bcma. Gas actually started arriving in Finland in 1974. In December 2015, Gazprom Export and Gasum extended the contract for gas supply to Finland through December 31, 2031.

As of January 1, 2020, Finland has imported about 130.3 bcm of the Russian gas, including 2.46 bcm in 2019.

For 25 years, Russia’s partner has been Finland’s Neste company, later renamed into Fortum. For many years, the companies have developed the Finnish natural gas market together. In 1994, the fruitful cooperation between Gazprom and Fortum resulted into the establishment of the joint-stock company Gasum, committed to importing and selling natural gas as well as operating and developing Finland’s gas transmission system. In 2016, Gazprom sold its stake in the company, and the Finnish state became the only shareholder of Gasum.
