How a battery earns in Lithuania

Lithuania's day-ahead zone is operated by TSO Litgrid, which in February 2025 synchronised the Baltic grids with Continental Europe — ending the Russian-controlled BRELL ring and turning Lithuania into a full EU‑market participant. Renewables already cover 68.1% of national demand (wind 4.29 TWh, solar 14.2%), yet grid congestion is now the binding constraint: distribution operator ESO is curtailing new solar connections while roughly 2 GW of battery projects hold technical permits. Storage is backed by a named subsidy — the APVA capex scheme (€180 M, funded via the EU Temporary Crisis & Transition Framework, 2024) covering up to 30% of cost, capped at €100,000 per MWh — and batteries also earn on the FCR and aFRR markets via the PICASSO & MARI platforms. The core play, though, is arbitrage: the 30‑day day-ahead spread averaged €126/MWh — 146% of the average price — the value a battery captures by charging cheap and discharging dear.
