The derogation from compliance with requirements under EU legislation granted for Finland by the European Union ended when the Balticconnector interconnector pipeline between Finland and Estonia was completed, and the Finnish gas market was opened to competition on 1 January 2020.

In an open gas market, the same company cannot be both a transmission system operator and a gas supplier. Therefore, transmission network operations were unbundled from Gasum Ltd into a separate company. From1 January 2020, the gas transmission network company Gasgrid Finland Oy owned by the State of Finland has been responsible for gas transmission in Finland.
