The Baltic states have been an "energy island" for a long time, connected only to the Russian gas supply system. The European Union is contributor of two undergoing gas interconnection projects, connecting Baltics with Finland and Poland.
GIPL (Gas Interconnector Poland - Lithuania) will connect Lithuania and Poland.
Balticconnector will connect Estonia and Finland.
Both projects are under construction and are sheduled for commissioning by 2022.
The Baltic region is heavily dominated by Russian gas supplies. Alternative supply channels has been considered in recent years. Since 2014 the LNG terminal in Klaipeda has served as an alternative LNG entry point in the region. However, the need for an effective long-term alternative LNG supply channel is still required. The Skulte LNG terminal project, along with Klaipeda LNG terminal and two Estonian projects in Paldiski and Tallinn are under consideration as a long-term solution for LNG import in the region.
The gas transmission system operators (TSOs) in Finland, Latvia and Estonia have signed an Inter TSO Compensation (ITC) agreement, which enables the functioning of a single gas transmission tariff zone for Finland, Estonia and Latvia from the beginning of 2020. The ITC agreement unifies the entry point tariffs on the external borders of the region and removes commercial interconnection points between countries. The Estonian - Finnish interconnection Balticconnector will be used for transportation of the gas across Finnish gulf without additional charges. Transportation of gas to and from Inčukalns UGS will also be ensured without additional entry/exit fee. The ITC agreement foresees compensation for TSOs of eligible variable costs and sets principles of the entry revenue re-distribution among the operators.
The markets of Finland (~2.5 bcm) and Poland (~20 bcm) will become connected to the Baltics, after Balticconnector and GIPL interconnection projects will be completed. The market of total volume more than 25 bcm will become available, and Latvia, Estonia and Finland (total ~4.5 bcm) will funciton as a single market already from 2020. More countries of the region could join the single market mechanism in the future, and Skulte LNG Terminal and Inčukalns UGS will play a critical role in supplying the region.
