Technical FAQs 4

How much does a battery energy storage system cost in Bulgaria?

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.

What will Bulgaria's solar power capacity be used for?

This capacity will be used for both solar peak shaving and grid balancing,” Rangelov said. Bulgaria’s Ministry of Energy is currently running two tenders aiming to commission 1,425 MW of solar and wind generation capacity coupled with 350 MW of behind-the-meter energy storage.

Why is energy storage growing in Bulgaria?

Energy storage in Bulgaria is expanding rapidly as the government awards nearly 10 GWh of capacity to 82 projects, boosting renewable energy reliability and grid stability.

How much battery capacity does Bulgaria have?

Bulgaria has installed between 40 MWh and 50 MWh of battery capacity to date, with business models mainly based on grid balancing and arbitrage.
