Lithuania Enters 2026 With a Storage-First Power Strategy
Lithuania’s transmission system operator Litgrid has preliminarily reserved almost 1.2 GW of grid capacity for energy storage projects over the past three months, marking one of the largest short-term storage allocations in the Baltic region.
Between September 7 and December 6, Litgrid approved 19 connection requests in full or in part, reserving 1,187 MW of permitted capacity for renewable and storage projects. Of this volume, 1,159 MW and 3,067 MWh were allocated to battery energy storage systems, while wind power accounted for 28 MW.
According to Litgrid, Lithuania’s total installed renewable capacity has already reached 5.7 GW, with intention protocols signed for more than 10 GW of additional wind and solar capacity to be developed over the next five years. The operator notes that most new applications now focus on storage projects with longer discharge durations — two, four, or more hours at full capacity.
The new grid capacity reservation cycle will remain open until March 6, 2026, with developers encouraged to submit applications by early February.
Why this matters for 2026 — and beyond
From renewable growth to system control
The decision to prioritise large-scale storage signals a structural shift. The Baltic power system is no longer constrained by a lack of renewable generation, but by the ability to balance variable output and maintain grid stability. Storage is becoming a system requirement, not an optional add-on.
Post-BRELL realities
As the Baltic states operate synchronously with continental Europe, system stability and frequency control increasingly depend on domestic balancing resources. Large-scale storage reduces reliance on emergency measures, forced curtailment of renewables, and extreme price volatility.
Regional price and risk effects
Lithuania’s storage build-up will have cross-border effects. Operating within the shared Baltic electricity market, new storage capacity can:
dampen extreme price spikes,
reduce negative price hours,
improve predictability for industrial consumers across Lithuania, Latvia, and Estonia.
A market signal for investors
Reserving grid capacity at this scale indicates that:
transmission infrastructure is ready for storage,
regulatory procedures are functioning,
energy storage is treated as core infrastructure.
For investors, this lowers regulatory uncertainty and clarifies where future balancing and flexibility markets in the Baltics are heading. BSM © 2026
