Enhancement of Latvia - Lithuania interconnection

Enhancement of Latvia-Lithuania interconnection (further referred as “the Project” or “ELLI”) was included into the 3rd PCI List adopted by the European Commission on 24 November 2017, in the BEMIP (Baltic Energy Market Interconnection Plan) Gas priority corridor. ELLI Project is an important element for completion of the EU internal energy market.

The current interconnection capacities and limited operating pressure (40 bar) in Latvian pipelines in the whole route from Lithuania to Estonia will limit the crossborder trade between the Member States. The implementation of the ELLI project eliminate the existing bottleneck between Latvia and Lithuania and will enhance the operating pressure up to 50 bar in Latvian pipelines that are relevant for cross-border flows between EU Member States. It will also increase diversification and security of supply, enhance the competition in the gas market, provide the opportunity for better capacity usage of Latvia’s Inčukalns Underground Gas Storage (UGS) for Lithuania and Poland, and use of gas import routes via LNG terminal in Klaipeda and via GIPL for Latvia, Estonia and Finland. The Project will serve for better integration and functioning of the gas markets of the Baltic States, Finland and overall BEMIP region.

The Feasibility Study and Cost Benefit Analysis for the Project was carried out in 2018. It identified the optimal technical alternative to implement the Project. The construction works will comprise the enhancement of the operating pressure up to 50 bar of the pipelines Rīga–Panevėžys, Rīga–Inčukalns UGS line I, Rīga–Inčukalns UGS line II, Voldaj–Pskov–Riga, Izborsk–Inčukalns UGS and Vireši–Tallinn on the territory of Latvia, as well as increase of capacity of Kiemenai Gas Metering Station and readjustment of piping of the Panevezys Compressor Station on the territory of Lithuania.

As a result of the accelerated implementation of the Lithuania-Latvia Interconnection Capacity Increase Project ELLI, the technical capacity of the Kiemenai interconnection point from 13 November 2023 is set at 90 GWh/d from Lithuania to Latvia with a possible dynamic increase to around 100 GWh/d, while from Latvia to Lithuania it is set at 82 GWh/d with a possible dynamic increase to around 100 GWh/d. Thanks to the successful operation of the TSOs, the first capacity increase for Kiemenai took place already in November 2022.
