Litgrid, the electricity transmission system operator, is responsible for ensuring the long-term security of the country’s power system, which requires regular assessments of the system’s adequacy, i.e., the system’s ability to maintain a balance between electricity generation and consumption, and to ensure the security of electricity supply at all times, under both normal and emergency conditions. Resource adequacy assessments are conducted annually at the European level as part of the European Resource Adequacy Assessment (ERAA) prepared by ENTSO-E.

What has already been accomplished and what remains to be done in the Harmony Link interconnection project with Poland?
The Harmony Link land-based interconnection is the final project of the Baltic states’ synchronisation with continental Europe. The electricity transmission interconnection between Lithuania and Poland will provide additional trading opportunities and become the second synchronous interconnection between the Baltic states and continental Europe. We spoke with Genadijus Andrejevas, head of the Harmony Link group at the Synchronization Program Implementation Centre, about the progress of this project, which is important for the entire region.

Fifth Commercial Battery Storage System with 80 MW Capacity Connected to the Electricity Transmission Network
Litgrid, Lithuania's electricity transmission system operator, has connected a battery storage park developed by the Enervia holding group in Panevėžys district. The battery system has a permitted generation capacity of 80 MW and a storage capacity of 186.26 MWh. The new energy storage units will contribute to maintaining the stability and balance of the electricity system as an ever-greater share of electricity is generated from renewable sources.

What will Lithuania’s electricity, gas, and hydrogen transmission networks look like in a decade?
Litgrid, the operator of Lithuania’s electricity transmission system, and Amber Grid, the operator of the gas transmission system, have prepared a joint development scenario for the electricity, gas, and hydrogen networks—the first of its kind in Lithuania. This scenario served as the basis for developing national ten-year (2026–2035) development plans for the electricity, gas, and hydrogen networks. Lithuania’s electricity and gas transmission system operators not only ensure the reliable operation of the systems on a daily basis but also plan the development of the country’s and the region’s electricity sector for the next ten years and beyond. The prepared ten-year network development plans will be submitted by July 1.

Litgrid Modernizes Power Transmission Network Maintenance: Launches Periodic Aerial Scanning
Litgrid, the Lithuanian power transmission system operator, is launching periodic aerial scanning of the country’s entire high-voltage power transmission network (110–400 kV). Over the next two months, more than 5,000 km of power lines will be scanned. This allows for the planning of necessary maintenance work before disruptions occur and ensures the consistent modernization of power grid maintenance.

For the first time in history, Lithuania’s weekly electricity demand was met entirely by renewable energy plants, with prices falling by 58 percent
In the penultimate week of April, for the first time in history, weekly production from renewable energy plants exceeded Lithuania’s electricity demand, driven primarily by increased wind power generation. Electricity prices were at their lowest since June of last year, with negative electricity prices also emerging, and more electricity was exported to Sweden than was imported from it.

The installed capacity of wind and solar power plants in Lithuania has reached 6 GW
The installed capacity of wind and solar power plants connected to Lithuania’s electricity transmission and distribution networks has reached 6 GW, according to data from Litgrid, the Lithuanian electricity transmission system operator. Since the beginning of this year, the capacity of renewable energy plants in Lithuania has increased by nearly 0.3 GW, and by nearly 2 GW over the past 12 months.

Lithuania ranks second in Europe for the share of electricity consumption met by wind power, and sixth for solar generation
In 2025, wind power plants in Lithuania supplied 33 per cent of the country's electricity consumption, placing Lithuania second in Europe by this measure, according to data from Lithuanian electricity transmission system operator Litgrid and the European wind energy industry association Wind Europe. Solar power plants in Lithuania last year accounted for 14 per cent of electricity consumption, ranking Lithuania sixth in Europe by the share of consumed electricity generated from solar.
