The Finnish Energy Authority has decided that Gasgrid Finland shall organize the public consultation in accordance with Article 26 of the TAR NC. The consultation documents can be found here.
The consultation period is from April 16th to June 16th, 2025. Before the tariffs for 2026 can be set, the Energy Authority must approve the reference price methodology according to the following schedule:

The consultation includes, inter alia: a description of the proposed reference price methodology and a comparison of the indicative reference prices (tariff of annual product) of postage stamp methodology and capacity weighted distance (CWD) methodology, preliminary information on TSO’s allowed revenue for 2026, commodity tariff estimates and non-transmission tariff estimates. Additionally, the consultation includes a description of the new tariff component proposed by Gasgrid, the connection capacity charge. During the last quarter of 2025, Gasgrid shall publish the document according to TAR NC article 30 about the final tariffs. The final tariffs will be published by 30.11.2025
