Preparations for open gas market

Finland’s new Natural Gas Market Act entered into force at the beginning of 2018. In addition to the reformed Act, the market opening also required rules, procedures and IT systems. Gasum’s TSO (transmission system operator) department coordinated the gas market rules formulation process in cooperation with customers and other stakeholders during 2017 – 2019. In addition to rules TSO has prepared contracts, transmission tariffs, IT systems and data exchange instructions for the open gas market. These web pages were Gasum’s TSO department’s information channel regarding Finnish gas market opening. 

Gasgrid Finland Oy started as the new TSO 1st Jan 2020. These web pages are no longer maintained and will be terminated during 2020. For up-to-date information about Finnish gas market please go to

Preparation of gas market rules has been done in working groups with customers, the Ministry of Economic Affairs and Employment, Energy Authority, Gasum, Baltic Connector Oy and other stakeholders. English translations (non-binding version) of shipper-related market rules were published in August 2019 (see below).

Gasum TSO has organized information events on the topic on May 15th, November 29th 2017, October 5th 2018, May 21st 2019 and 30th Sep 2019 in Helsinki, Finland. The aim of the work was to prepare national rules for Natural Gas Market, that will enable a well-functioning, non-discriminatory and cost-effective national market. Public consultation regarding market rules and contracts was held in March-April 2019 and another public consultation regarding terms of TSO’s services during 31st May – 14th June 2019. Finalised rules in Finnish were published in July 2019 after Energy Authority had approved the terms of TSO’s services. Non-binding English translations of rules and guidelines are available at
