Amber Gas Corridor
About the initiative
Amber Gas Corridor is a regional initiative creating a reliable and competitive gas transmission route from the Baltic-Finnish region to Central and Eastern Europe. The initiative is based on existing infrastructure and cooperation between transmission system operators:
- Amber Grid (Lithuania),
- KN Energies (Lithuania),
- Conexus Baltic Grid (Latvia),
- Elering (Estonia),
- Gasgrid Finland (Finland),
- GAZ-SYSTEM (Poland).
Benefits for Market Participants
- Easy market access. A clear and simple registration process enables quick entry to the Baltic–Finnish gas markets.
- Capacity availability. Capacities are often available at key cross-border interconnection points between Finland and the Baltic States, as well as between Lithuania and Poland.
- Transparent capacity booking. At interconnection points, capacities are booked via the GSA Platform capacity booking platform, applying clear, transparent, and market-based allocation procedures.
- Competitive transportation routes. The corridor provides a reliable alternative to existing gas supply routes, ensuring competitive transportation costs and transparent pricing.
- Security of supply and route flexibility. Gas supply is supported by LNG terminals and gas storages. Market participants can choose different transportation routes and shape gas flows from Finland (Inkoo) or Lithuania (Klaipėda) according to market needs.
AMBER GAS CORRIDOR PARTNERS DELIVER IMPROVEMENTS FOLLOWING MARKET FEEDBACK
In early 2026, Amber Gas Corridor partners conducted a market survey to better understand the needs and expectations of gas market participants using or considering the route from the Inkoo and Klaipėda LNG terminals towards Central and Eastern European markets. The survey received responses from 41 market participants, who shared valuable insights on route accessibility, capacity booking, tariffs, maintenance coordination, regulatory requirements and operational processes.
Following a joint review of the feedback received, the Corridor partners agreed on a number of practical measures aimed at improving the transparency, accessibility, coordination, and competitiveness of gas transportation along the route. The actions cover six key areas: capacity and route booking simplification, tariff competitiveness and transparency, regulatory requirements and access to the Polish market, maintenance and capacity coordination, balancing and transmission rules, and nomination processes, including further alignment and standardisation of Edig@s-based data exchange practices.
Some of the measures have already been implemented, including the introduction of lower transmission and regasification tariffs at several points along the Amber Gas Corridor for 2027, the preparation of the Amber Gas Corridor Practical Shippers’ Guide and the initiation of enhanced regional maintenance coordination activities. Other actions will be progressed jointly by transmission system operators and LNG terminal operators as part of the agreed work programme.
The document below summarises the feedback received, the actions agreed by the Corridor partners and the next steps planned to further improve customer experience and support efficient, transparent and reliable cross-border gas transportation across the region.
