Bulgaria''s Battery Energy Storage Market Outlook 2025–2034
Battery Energy Storage Systems are no longer optional — they are essential for ensuring grid stability, integrating renewables, and meeting EU climate commitments.
Specifically, according to data presented by Soltani at the RE-Source Southeast Conference, Bulgaria's electricity market offers an opportunity for €110 per MWh profit with a battery energy storage system with two hours of discharge capacity using energy arbitrage. Rystad Energy's analysis has set the battery system costs at a flat €60 per MWh.
Another development that can boost battery storage in Bulgaria is a recent update of national legislation to include battery energy storage systems as a component of the grid.
Sepehr Soltani, lead energy storage analyst at Norwegian consultancy Rystad Energy told the RE-Source Southeast Conference that took place in Sofia, Bulgaria, in May that Bulgaria offers the highest revenue potential for battery storage in Europe.
Bulgaria has installed between 40 MWh and 50 MWh of battery capacity to date, with business models mainly based on grid balancing and arbitrage.
