Bulgaria reached a critical milestone in its renewable energy transition in 2025, building 1,416 MW (1.4 GW) of new solar photovoltaic (PV) capacity — its third consecutive year above 1 GW - bringing the
Bulgaria installed 1,416 MW of new solar capacity last year, extending its run of annual additions above 1 GW to a third straight year and raising total installed solar capacity to 5,984 MW,
This major public investment follows growing private-sector activity. As reported in our previous article, SUNOTEC and Sungrow signed a landmark agreement in July 2025 to deploy
the load flexibility of energy storage within its portfolio to balance output. Moreover, given balancing costs can make up to 10 percent of the final electricity prices in Bulgaria, utilizing energy storage to
At the close of 2024, Bulgaria''s solar PV capacity had already reached 3.91 GW—an annual increase of over 1 GW. These developments come on the heels of Bulgaria''s first renewable
Bulgaria''s solar sector added 1.4 GW in 2025 and is poised for a record 2 GW+ in 2026, driven by competitive projects and BESS integration, though high eco-taxes pose a challenge.
Bulgaria will finance 82 standalone renewable energy storage projects worth over 1.15 billion levs ($675 million) under its EU-funded procurement exercise named RESTORE.
Bulgaria''s second standalone energy storage procurement exercise of 2025, worth close to BGN 229 million, received a lot of interest and there are 30 project proposals included in a reserve
In Bulgaria, the storage of solar energy in batteries is rapidly expanding, with private investors leading the initiative.
The tender was launched last year, aiming to significantly increase the share of renewable energy, mainly wind and solar, in the country''s energy mix. It would also contribute to
