Amber Grid AB is the operator of Lithuania's natural gas transmission system, responsible for the transportation of natural gas to power generation facilities, industrial enterprises, and municipal distribution networks, as well as the management of cross-border gas transit. Founded in 2013 following the unbundling of Lietuvos Dujos under the European Union Third Energy Package and headquartered in Vilnius, Lithuania, the company operates as a subsidiary of state-owned energy holding group EPSO-G UAB. Amber Grid AB manages, maintains, and develops the high-pressure gas transmission infrastructure of the Republic of Lithuania, interconnecting regional energy markets across the Baltic States, Poland, and continental Europe.
The company provides a comprehensive range of gas transmission and system balancing services, comprising: high-pressure natural gas transportation across domestic and cross-border transmission pipelines; entry and exit transmission capacity allocation and booking services for energy suppliers, traders, and wholesale market participants; gas flow dispatching, pressure control, and physical grid balancing; technical infrastructure maintenance, pipeline inspection, and diagnostic engineering services for compressor stations, gas distribution stations, and metering points; integration and grid connection services for commercial biomethane production plants; and administration of the national Guarantees of Origin (GO) registry for renewable gas. The company's infrastructure links key regional energy assets, including the Klaipėda liquefied natural gas (LNG) import terminal, the Inčukalns underground gas storage facility via the Latvia-Lithuania interconnector, and the European gas network via the Gas Interconnection Poland-Lithuania (GIPL).
In recent developments, Amber Grid AB has expanded its strategic focus toward renewable energy integration and regional decarbonization infrastructure. As part of a cross-border consortium with transmission system operators from Finland, Estonia, Latvia, Poland, and Germany, the company is advancing the Nordic-Baltic Hydrogen Corridor (NBHC) initiative to build a dedicated cross-border hydrogen infrastructure network across the region. Following the successful commissioning and integration of the GIPL pipeline and the capacity expansion of the Enhancement of Latvia-Lithuania Interconnection (ELLI), the company has connected the country's first commercial biomethane production facilities to the national transmission grid, implemented automated methane emission detection technologies, and initiated comprehensive pipeline retrofitting and testing programs to support future hydrogen blending and pure hydrogen transport.
