Contracts for 6,000 MWh of Battery Energy Storage Capacity Have Been Signed Under the RESTORE Tender Program in Bulgaria
/LONDON, September 9, 2025, 11:45 BST, Renewable Market Watch™/
Bulgaria is situated in the South-Eastern part of the Balkan Peninsula. The country’s population is 7.284 million people, and its territory spans 110,912 sq.km. Bulgaria borders Greece and Turkey to the South, and North Macedonia and Serbia to the West. The Danube River to the North is our natural border with Romania; the Black Sea is situated to the East. Bulgaria is in the centre of a region which is undergoing a dynamic transition. Within 500 km of our capital city, Sofia (1.4 million people), a population of over 90 million lives in 9 countries that have recently embarked on their way to a market economy. This is a large market with rapidly increasing purchasing power.
In the last few years, Bulgaria has been the focus of investors’ interest. The political stability and predictability afforded by NATO membership and EU accession, the stable economic outlook, and the country’s growing credit rating following its acceptance into the Eurozone on 1 January 2026, along with its established institutions, were just some of the elements that attracted investors’ interest. External investors have been attracted by the rapidly developing national industry, a highly skilled workforce and a significant new market.
The Bulgarian solar power market has been experiencing significant growth since 2021. As a result of the high economic growth over the last three years, industrialisation and urbanisation, the demand for new energy generation sources to replace coal-based power plants in Bulgaria is increasing. By the end of 2024, Bulgaria had a cumulative installed solar capacity of 4,568 MW (4.57 GW), representing an increase of 1,283 MW (1.28 GW) compared to 2023. The rapid growth of solar PV capacity in Bulgaria necessitates a corresponding increase in battery storage to prevent grid imbalance issues. The battery energy storage system (BESS) market in Bulgaria is expected to experience robust growth by 2030 in the co-located/behind-the-meter (BTM) and front-of-the-meter (FTM) segments.
Recently, contracts have been signed for a total of 6,000 MWh of installed battery capacity as part of the initiative aimed at developing a comprehensive national infrastructure for storing energy derived from renewable sources, known as the RESTORE program. This initiative is financially supported through the Bulgarian Recovery and Resilience Plan. For more information, you may read the article:
In addition to the battery energy storage system (BESS) projects approved for funding after the latest tender (RESTORE), another 1,900 MWh of electricity storage systems will be added in the second part of the program in Bulgaria (RESTORE 2), and the total amount of grant funding they will receive is over BGN 230 million (EUR 117.6 million). Under the newly discussed procedure, BESS facilities need to be built, installed, connected to either the electricity transmission or distribution network, and put into operation by July 31, 2026.
Several large-scale solar photovoltaic (PV) projects and battery energy storage system (BESS) projects with a capacity exceeding 50 MW have been announced in Bulgaria since 2023, and these projects are scheduled to be built between 2025 and 2028.
