Balticconnector Gas Pipeline

From Global Energy Monitor
This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.

Balticconnector Gas Pipeline is a bi-directional natural gas pipeline project between Siuntio, Finland, and Kiili, Estonia, which connects the Estonian and Finnish gas grids.[1][2]


The pipeline links Siuntio, Finland to Paldiski, Estonia.[3][4]

  • Financing: Connecting Europe Facility €3,822,160 grant for preparatory studies and €187,500,000 grant for construction[9]; equity investments of €31,250,000 each from the Finnish state and Elering[10]

The 150-kilometer natural gas pipeline is segmented into three divisions; a 22-kilometer Finnish onshore section, an 81-kilometer offshore section on the seabed of the Gulf of Finland, and a 47-kilometer Estonian onshore section.[8] The project is composed of pipeline systems, stations and facilities to connect the existing gas networks in Finland and Estonia. The capacity of the pipeline is 7.2 million cubic meters per day.[11]

The total cost of the project is reported to be 250 million Euros[11][8]. The European Union’s Connecting Europe Facility fund provided the project with a grant of 3,822,160 euros for preparatory studies in 2014, and a further grant of 187,500,000 euros in 2016 which covered 75% of the construction costs.[9] Finland and the Estonian national transmission system operator Elering completed the financing with an equity investment totalling 62,500,000 euros.[10] The pipeline was scheduled to begin construction in 2018[12].

As of July 2019, construction work for the offshore portion of the pipeline was complete, including pipe laying and shielding. The next planned step was to pressure test the offshore pipeline in July-August of 2019, after which the pipeline would be emptied and dried. The offshore pipeline was planned to be connected to the onshore pipelines in Finland and Estonia during the fall of 2019. The pipeline was expected to be fully ready at the end of 2019, and that gas will start to flow in the pipeline on 1 January 2020 as the Finnish gas market opens.[13]

In November 2019 the Finnish and Estonian parts of the pipeline were successfully connected and gas-flow was established.[14] The pipeline began operation on January 1, 2020.[15]


European Network of Transmission System Operators for Gas (ENTSOG) refers to the project on its Ten Year Network Development Plan as TRA-F-895 in Estonia and TRA-F-928 in Finland.[16]

It's Project of Common Interest (PCI) number is 8.1.1.[17][18]

Sci_Grid in its combined IGG gas transmission network data set refers to the pipeline as INET_PL_11270, INET_PL_11271, INET_PL_1130.[19]
