Lithuania’s energy system is shaped by a national goal that goes beyond lower prices or cleaner electricity: independence. The country spent decades connected to energy networks controlled from the east, imported much of its electricity, and relied on foreign oil and natural gas. It has responded by building an LNG terminal, connecting its power and gas systems to the rest of the European Union, expanding wind and solar generation, and leaving the Russian-controlled electricity system.
Lithuania still imports fossil fuels and some of its electricity, but the direction has changed. Domestic renewable generation is rising quickly, the national grid now operates with continental Europe, and strategic infrastructure at Klaipėda, Mažeikiai, Kruonis and the Polish border has turned the country into an important Baltic energy link.
Energy Independence Became Lithuania’s Central Strategy
Energy policy in Lithuania cannot be separated from the country’s history and security concerns. After restoring independence in 1990, Lithuania inherited an energy system built around Soviet infrastructure. Oil pipelines, gas connections and electricity networks were designed to link the Baltic region with Russia and Belarus rather than Western Europe.
Lithuania spent the following decades reducing that dependence. The process included building new cross-border links, opening the Klaipėda liquefied natural gas terminal, joining the Nordic electricity market and developing domestic renewable energy. In 2022, Lithuania stopped importing Russian gas, oil and electricity for its own needs. This was possible because alternative infrastructure had already been built.
The most important recent step came in February 2025, when Lithuania, Latvia and Estonia disconnected from the Russian-controlled IPS/UPS electricity system and synchronised with continental Europe. Lithuania’s grid is now managed as part of the wider European synchronous system rather than the network that once connected the Baltic states with Russia and Belarus.
This transition has changed the meaning of Lithuanian energy infrastructure. An interconnector, LNG terminal or battery park is not treated only as a commercial asset. It is also part of national security, political independence and the country’s deeper integration into Europe.
Lithuania’s Electricity Mix Is Changing Faster Than Its Reputation
For many years, Lithuania was known as a country that imported most of its electricity. The closure of the Ignalina Nuclear Power Plant removed the country’s largest generating source and turned Lithuania from a major electricity exporter into a net importer. In 2022, domestic power plants met only about one-third of national electricity demand.
That picture is changing quickly. Lithuania produced about 9.7 terawatt-hours of electricity in 2025, compared with roughly 4.3 TWh in 2022. Local power plants supplied approximately 74% of national demand in 2025, leaving imports to cover the remaining 26%. Wind and solar provided much of the growth, while thermal plants, hydropower and pumped storage continued to support the system.
Lithuania still participates heavily in regional electricity trade. Power can move through NordBalt, the undersea connection with Sweden, LitPol Link with Poland, and links with Latvia. Imports remain useful when Nordic hydropower, Swedish nuclear generation or regional market conditions offer lower-cost electricity. Exports are becoming more common during periods of high domestic wind and solar output.
The result is not full electricity self-sufficiency every hour. Lithuania is instead building a more flexible system in which domestic renewables, regional trade, storage and reserve generation work together.
Synchronisation With Europe Changed the Grid’s Political Geography
Lithuania’s electricity grid was physically connected to European markets before 2025, but its frequency was still controlled through the BRELL system linking Belarus, Russia, Estonia, Latvia and Lithuania. This created a strategic weakness: Lithuania could buy and sell electricity in European markets while remaining technically tied to an eastern power system.
Synchronisation with continental Europe ended that arrangement. Lithuania and the other Baltic states now operate in the same synchronous area as most of the European Union. The transition required new transmission lines, substations, frequency-control equipment, system tests and closer cooperation with Poland.
The LitPol Link connection between Lithuania and Poland became especially important because Poland provides the physical route into the continental European synchronous area. A planned second connection, Harmony Link, is intended to increase transmission capacity between the Baltic system and Central Europe. Lithuania has moved toward an overland alternating-current design for this project rather than relying only on an undersea direct-current cable.
NordBalt remains another important part of the system. The 700 MW connection beneath the Baltic Sea links Lithuania with Sweden and the wider Nordic electricity market. Together, NordBalt, LitPol Link and the Latvian connections allow Lithuania to trade power, manage shortages and make better use of periods when domestic renewable output is high.
Natural Gas in Lithuania Is Now a Question of Routes, Not Russian Control
Lithuania has limited domestic natural gas production, so its gas system depends on imports. The key change is that the country now has several possible routes and is no longer dependent on a single Russian pipeline supplier.
The Klaipėda LNG terminal is the centre of this new structure. Its floating storage and regasification unit, named Independence, receives liquefied natural gas delivered by ship. The vessel can store 170,000 cubic metres of LNG, convert it back into gas and send it through an 18-kilometre pipeline into Lithuania’s transmission network.
The terminal began commercial operations in 2015 and gave Lithuania access to the global LNG market. Lithuania purchased the vessel in 2024, securing its operation through at least 2044. The terminal now serves more than the Lithuanian market. Gas arriving at Klaipėda can travel to Latvia, Estonia and Poland, while regional customers can reserve terminal capacity directly.
The Gas Interconnection Poland–Lithuania, known as GIPL, added another strategic route in 2022. It connected the Baltic gas system with Poland and the wider continental European network. Gas can move in either direction, allowing Lithuania to import through Poland or send LNG received at Klaipėda southward.
Natural gas remains important for industry, combined heat and power plants, fertilizer production and reserve electricity generation. However, Lithuania does not view large-scale gas expansion as its main long-term energy strategy. Gas plants are more likely to provide flexible capacity during low-wind and low-solar periods than to supply most of the country’s electricity.
Oil in Lithuania Is an Industrial and Transport Story
Lithuania is not a major crude oil producer, but it has one of the most important petroleum facilities in the Baltic region. The Mažeikiai refinery in northwestern Lithuania is the only crude oil refinery in the Baltic states. It has a design capacity of about 10 million tonnes per year, with an efficient operating volume of approximately 8 million tonnes under normal market conditions.
The refinery once received most of its crude through the Druzhba pipeline system from Russia. Today, its main supplies arrive by sea through the Būtingė oil terminal on Lithuania’s Baltic coast. Crude is unloaded offshore and transported by pipeline to Mažeikiai. This route allows the refinery to process oil from international suppliers without depending on Russian pipeline deliveries.
Mažeikiai produces diesel, gasoline, jet fuel, liquefied petroleum gas and other refined products for Lithuania and export markets. The refinery, Būtingė terminal, pipelines and rail-loading infrastructure make oil refining an important part of Lithuania’s industrial economy even though the country has little domestic crude production.
Oil also remains the largest challenge in Lithuania’s energy transition because transport depends heavily on petroleum. Transport accounts for around 40% of final energy consumption and about three-quarters of national oil demand. Road transport dominates, and Lithuania has an older vehicle fleet than many other EU countries.
This means that renewable electricity alone will not quickly remove Lithuania’s fossil fuel dependence. Electric vehicles, rail investment, public transport, charging infrastructure, renewable fuels and more efficient freight systems will all be needed to reduce oil consumption.
Coal Has Only a Small Place in Lithuania’s Energy System
Coal is not a major source of Lithuanian electricity and the country does not have a large coal-mining industry. This separates Lithuania from coal-dependent Central and Eastern European energy systems such as Poland, Czechia or parts of the western Balkans.
The remaining use of coal and other solid fossil fuels is relatively limited. Small quantities have traditionally been used in household heating, industrial processes and commercial boilers. Some homes also use peat briquettes and other solid fuels, although wood and biomass are much more important in the Lithuanian heating market.
Lithuania therefore does not face the same coal phaseout problem as countries with large mining regions and fleets of coal-fired power stations. Its fossil fuel challenge is concentrated more strongly in oil-dependent transport, imported natural gas and the need for reliable reserve power.
The limited role of coal also gives Lithuania a different starting point for decarbonisation. It does not need to replace a dominant coal power sector, but it must manage the more complex task of reducing petroleum use, modernising buildings and providing backup for a power system increasingly based on variable wind and solar generation.
Ignalina Still Defines the Nuclear Energy Debate
Lithuania currently has no operating nuclear power plant, but nuclear energy remains central to its energy history. The Ignalina Nuclear Power Plant once generated most of the country’s electricity and made Lithuania a major electricity exporter. Its two RBMK reactors were similar in design to the reactors used at Chernobyl.
Lithuania agreed to close Ignalina as part of its entry into the European Union. The first reactor stopped operating in 2004 and the second in 2009. The plant is now undergoing a long decommissioning process involving spent-fuel storage, reactor dismantling, radioactive waste management and eventual site restoration. The programme is scheduled to continue into the 2030s.
The closure created a lasting debate. Lithuania gained closer European integration and removed an aging reactor design, but it also lost a large source of domestic low-carbon electricity. Gas generation and electricity imports increased after the shutdown.
Nuclear power may return in a different form. Lithuania’s current energy strategy allows the government to study small modular reactors as a possible source of stable, low-carbon power. A decision on whether to proceed is expected by 2028 under the national strategy. The planning scenario considers up to 1.5 GW of nuclear capacity, with a possible first 0.5 GW unit in operation around 2038.
No new reactor has been approved for construction. Cost, technology readiness, regulation, public acceptance and the growth of storage will all influence the decision. Lithuania’s existing nuclear expertise and the Ignalina site may support future planning, but wind and solar remain the country’s immediate priorities.
Wind and Solar Are Rebuilding Domestic Electricity Production
Renewable energy growth is the main reason Lithuania is becoming less dependent on imported electricity. By the end of 2025, the combined capacity of wind and solar plants had reached about 5.5 GW, compared with less than 1 GW fewer than four years earlier.
Onshore wind has become a leading source of domestic electricity. Lithuania’s flat landscape, open agricultural land and Baltic weather conditions provide useful wind resources, especially in western and central parts of the country. Large projects can increasingly operate without direct subsidies, although grid capacity and electricity prices still affect investment.
Solar power has grown even faster in capacity terms. Utility-scale solar parks are being joined by rooftop systems and remote solar farms used by households that cannot install panels on their own property. Lithuania’s “producing consumer” model allows residents to purchase or rent part of a solar project located elsewhere and receive credit for the electricity it produces.
Seasonal conditions remain important. Lithuania has long summer days but short, dark winters, so solar generation is much stronger during the warmer months. Wind can provide more electricity during autumn and winter, making the two technologies partly complementary.
Offshore wind could add another major source of power. Lithuania’s 2030 objectives include 1.4 GW of offshore wind, alongside 4.5 GW of onshore wind and 4.1 GW of solar capacity. However, offshore development has moved more slowly than hoped. An auction failed to attract enough interest in 2024, reflecting high financing costs, supply-chain pressure and investor uncertainty across the European offshore wind sector.
Biomass and District Heating Are a Major Part of the Energy Picture
Electricity receives most of the attention, but heating is equally important in Lithuania’s cold climate. Many cities use district heating networks that distribute hot water from central plants to apartment buildings, public facilities and businesses.
Biomass has replaced much of the natural gas once burned in these systems. In 2022, renewable sources—mainly biomass and the renewable share of municipal waste—produced more than 73% of Lithuania’s district heat. Wood chips, forestry residues and other biofuels therefore play a larger role in Lithuania’s energy system than coal.
Biomass has helped reduce gas imports and supported a domestic fuel market, but Lithuania does not expect wood-based energy to expand without limits. Air pollution, forest sustainability and fuel efficiency remain concerns, especially in homes using old wood-burning equipment.
The longer-term strategy is to combine biomass with large heat pumps, waste heat, electric boilers, thermal storage and cleaner fourth-generation district heating networks. This approach would allow surplus wind and solar electricity to be used for heat rather than curtailed when production exceeds immediate power demand.
Storage and Flexible Infrastructure Will Decide the Next Stage
Lithuania’s renewable expansion is moving faster than some parts of its grid. Wind and solar projects can often be developed in less time than new transmission lines, substations and distribution upgrades. This creates a risk that generation will be ready before the network can carry its electricity.
The country has already invested in flexibility. The Kruonis Pumped Storage Hydroelectric Plant can pump water uphill when electricity is abundant and generate power when demand is high. It is one of the most important balancing assets in the Baltic region.
Lithuania also operates four large battery parks located near Vilnius, Šiauliai, Alytus and Utena. Together, they provide 200 MW of power and 200 MWh of storage. The batteries can respond within one second to grid disturbances, helping control frequency while slower reserves start operating.
More storage will be needed as renewable capacity grows. Lithuania’s long-term strategy considers up to 4 GW of batteries by 2050, as well as hydrogen production, flexible industrial demand, heat storage and stronger international connections. The main challenge is no longer proving that Lithuania can build wind and solar plants. It is creating a system that can use their electricity at the right time and move it to the right place.
Lithuania’s Energy Future Could Shift From Importer to Exporter
Lithuania’s 2050 strategy imagines a country producing far more electricity than it uses today. The central planning scenario includes 10 GW of onshore wind, 4.5 GW of offshore wind and 9 GW of solar power. Electricity production could reach 74 TWh per year, compared with present demand of roughly 13 TWh.
Much of that future electricity would not be used directly in homes. It could power transport, industrial heat, data centres, large heat pumps and hydrogen electrolysers. Lithuania hopes that renewable hydrogen, ammonia, methanol and other synthetic fuels could become new export industries.
The scale of this plan creates uncertainty. Hydrogen demand has developed more slowly than expected across Europe, offshore wind projects remain expensive, and grid construction must keep pace with new generation. Lithuania must also improve building efficiency and reduce energy poverty while investing billions of euros in infrastructure.
Even so, the direction is clear. Lithuania has already changed from a country defined by Soviet-era energy dependence into a Baltic state connected to European electricity and gas markets. Its next task is more ambitious: using domestic wind, solar, biomass, storage and possibly nuclear power to move from energy security through diversification toward energy independence through production.
