Unlike the "optional" energy storage demand in some markets that relies on policy subsidies, Lithuania's energy storage layout fundamentally carries the essential attribute of "grid independence."

In February 2025, Lithuania, together with Latvia and Estonia, completed the synchronous interconnection with the EU continental power grid, completely bidding farewell to the Russian-Belarusian BRELL ring network that had been in operation for nearly 50 years. Behind this milestone event is Lithuania's urgent need for "energy autonomy"—after breaking away from the original power grid, how to ensure frequency stability, cope with fluctuations in renewable energy, and avoid power supply gaps? Energy storage has become the only solution.

The actions of Lithuania's main power grid company Litgrid are highly representative: as early as 2023, it collaborated with Fluence to launch a 200MW/200MWh "Energy Storage as Transmission" project. This project not only undertakes daily peak shaving tasks but also serves as a "backup power source for islanded operation," which can be quickly activated in the event of sudden grid failures to ensure power supply to core areas. This "safety first" positioning has given Lithuania's energy storage projects a rigid "non-cancelable" nature from the planning stage.

At the same time, the explosive growth of renewable energy further amplifies the demand for energy storage. Data shows that Lithuania's solar power installed capacity has exceeded 2GW in 2024, achieving the 2030 target six years ahead of schedule; onshore wind power has also achieved "grid connection without subsidies," becoming the main force for electricity increment. However, according to the "National Energy Independence Strategy," Lithuania's renewable energy installed capacity needs to reach 10.3GW by 2030 (photovoltaic 4.1GW + onshore wind 4.5GW + offshore wind 1.4GW) — with such a large-scale volatile power source integration, based on the internationally accepted 15%-20% energy storage ratio, more than 4GWh of additional energy storage capacity will be required before 2030, and the market increment is clearly visible.

For professionals focusing on overseas markets, what is most attractive about Lithuania is the "real financial support" of the "EU + local" dual policy, which precisely meets the needs of energy storage projects, from funding subsidies to cost optimization.

As a member state of the European Union, Lithuania can directly apply for special funds at the EU level, with priority given to energy storage projects related to "grid security and renewable energy integration":

“Post-pandemic era energy infrastructure upgrade,” Lithuania's Energy Cells company received 87.6 million euros in support from the fund for its 200MW energy storage project, covering 80% of the project investment;

"Cross-regional energy storage coordinated with the EU power grid," such as the energy storage interconnection project in the Baltic States planned by Litgrid.

Although the application threshold for this type of fund is relatively high, it excels in large amounts and long cycles, making it suitable for large-scale, strategic energy storage projects.

Lithuania's local policies are more grounded, providing targeted support from the Pre-RTB stage to the operational stage:

150,000 euros/MWh, and clearly stating "TSO (Transmission System Operator) project priority" — companies that layout such projects can directly enjoy subsidies, reducing investment costs by about 30%;

Financing at low interest rates of "3+EURIBOR" can be applied for both DSO (Distribution System Operator) and TSO projects, effectively alleviating the funding pressure in the early stages of the project;

"Battery procurement cost deduction" (the current battery price has dropped to 100,000 euros / MWh), "land leasing as an alternative to purchase," taking the Bitenai substation energy storage project as an example, leasing land can reduce more than 60% of the initial land investment.

Even companies with smaller capital scales can find opportunities in Lithuania — the "25% partial ownership model" allows investors to participate in energy storage projects with a cost of only 0.015M euros/MWh, while enjoying the same subsidy eligibility as full investors, significantly lowering the entry threshold.

In addition to policy dividends, the various energy storage projects that Lithuania has implemented have become "practical samples" for industry reference, covering different technological routes, application scenarios, and cooperation models.

The Ignitis 291MW/582MWh energy storage project, launched in 2025, is a representative work of grid-level energy storage in Lithuania:

“2 hours of long-term energy storage + second-level frequency modulation” can simultaneously meet the needs of grid frequency regulation and black start;

"Source Network Storage" Collaboration;

"International equipment manufacturer (Rolls-Royce) + local operator (Ignitis)", the former provides standardized technical solutions, while the latter connects grid resources and policies. The project is expected to become the largest single energy storage project in the Baltic Sea region after it is put into operation in 2027.

The 180MWh energy storage project in collaboration with the Lithuanian local EPC company Stiemo by Trina Storage provides a "quick implementation" model for regional-level energy storage:

According to the project document disclosure, the Bitenai substation in Lithuania is advancing 8 Pre-RTB phase energy storage projects, with a total scale of 200MW-400MWh, and individual project capacities of 20MW-40MWh or 30MW-60MWh, scheduled for centralized launch in Q4 2026. These "substation cluster energy storage" projects are directly laid out around the core nodes of the power grid and, after being put into operation, will become the "regulation hub" of the regional power grid, as well as an incremental area that enterprises can focus on in the future.

The energy storage value of Lithuania goes beyond the domestic market — as the "energy hub" of the Baltic States, its future will form a "storage synergy network" with Latvia and Estonia, amplifying market space.

Currently, Latvia has planned for renewable energy to account for 57% by 2030, requiring supporting 1.5GWh of energy storage; Estonia holds 11GW of wind power reserves and needs to implement 800MWh of energy storage before 2028. The three countries have achieved interconnection through the HarmonyLink power grid, which means:

This "one country layout, three countries benefit" synergy has made Lithuania the "best entry point" for entering the Baltic Sea energy storage market.

Our company is closely monitoring the rapid development and ongoing opportunities in the Lithuanian energy storage market. Several projects have already entered the preliminary RTB stage, with clear implementation paths and advancement milestones. As a key node in the EU's energy security strategy, Lithuania not only has clear policy support and a demand for large-scale projects but also demonstrates the potential to connect the entire Baltic region.
