Bulgaria has installed between 40 MWh and 50 MWh of battery energy storge capacity to date. However, new national legislation as well as funds provided through the European Union’s Recovery and Resilience Facility (RRF) could add another 1 GWh of storage capacity over the next two years.
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.
“In fact, we are already seeing the transition to energy storage in Bulgaria, mainly through the development of battery storage facilities behind-the-meter,” Alexander Rangelov, CEO of the International Power Supply (IPS) Group, an energy storage manufacturer headquartered in Sofia, told pv magazine.
That capacity will be used for both solar peak shaving and grid balancing. The Bulgarian Energy Ministry opened a tender procedure for supply of energy storage on August 21, 2024. The procedure aims to provide funding for construction and implementation of a 3,000 MWh stand-alone battery storage facility.
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.
As Europe races toward climate neutrality, Bulgaria’s surge in storage capacity signals a shift not only in national priorities but also in regional energy dynamics.
