How a battery earns in Latvia

Latvia's day-ahead zone is operated by AST (Augstsprieguma tīkls) inside the Nord Pool Baltic market. Since 9 February 2025 the Baltics run synchronously with Continental Europe, and the Baltic Balancing Capacity Market now pays batteries for reserves — FCR and mFRR from February, aFRR from 15 April 2025. Roughly 54 % of electricity is renewable (hydro-dominated, with solar up more than 18× since 2021), and AST reports no material curtailment below ~2,500 MW of variable renewables today. Latvia has no dedicated utility-scale storage subsidy (unlike Lithuania's capex scheme) — only a residential battery grant up to €2,500 (≥5 kWh, running to 2029); AST itself built an 80 MW / 160 MWh fleet via EU RePowerEU and CEF funds. The revenue engine is arbitrage: the 30-day day-ahead spread averaged about €127 / MWh — 150 % of the average price.
