Hybrid Interconnector for Baltic States and Germany
Lithuania, Latvia, and Germany have reached an agreement on the concept for a new hybrid offshore electricity interconnector. The project, set to span approximately 600 kilometers beneath the Baltic Sea, is designed to deliver up to 2 gigawatts (GW) of clean power between the Baltic States and Germany, with a targeted completion between 2035 and 2037.
A Strategic Energy Corridor
The proposed interconnector will connect Germany to either Lithuania or Latvia pending further technical studies. The project is being developed by the transmission system operators Litgrid (Lithuania), Augstsprieguma tīkls (Latvia), and 50Hertz (Germany), with strong backing from their respective national energy ministries.
Observers say the interconnector will become an important aspect of the EU’s vision for a meshed offshore grid in the Baltic Sea, enhancing the resilience of electricity supply and fostering deeper integration of renewable resources, particularly offshore wind and solar.
“The hybrid interconnector will not only reinforce our energy security but also unlock vast renewable energy potential in the Baltic region,” said a spokesperson for the Lithuanian Ministry of Energy. “This is a critical step toward meeting the EU’s climate targets and creating a truly integrated European electricity market.”
By linking the Baltic States with Germany, the project will enable the export and import of green electricity, supporting the development of new offshore wind farms and other renewable projects.
The partner TSOs are set to submit a joint application in May 2025 for inclusion in the European Network of Transmission System Operators for Electricity (ENTSO-E) Ten-Year Network Development Plan 2026. This is a prerequisite for the project to be recognized as a Project of Common Interest (PCI) by the European Union, opening the door to potential EU funding and streamlined permitting.
Following the application, a series of socio-economic and technical assessments will determine the optimal route and connection point in the Baltic States.
The hybrid interconnector complements existing and planned infrastructure, including LitPol Link (Lithuania-Poland), NordBalt (Lithuania-Sweden), and EstLink (Estonia-Finland). It is also a priority in Lithuania’s government program and aligns with the EU’s broader goals of energy market integration and decarbonization.
While detailed route maps and technical details have yet to be released, stakeholders can expect further updates as the project advances through the planning and approval process.
