Bulgaria launches first battery gigafactory and a major hybrid energy storage project.
Bulgaria has launched its first battery storage gigafactory near Sofia, with International Power Supply’s X1 facility beginning production at 3 GWh annually, expandable to 5 GWh by mid-2026.
The factory, designated a Strategic Project by the European Commission, manufactures most components in-house, relying only on external lithium iron phosphate cells.
Simultaneously, Renalfa IPP activated the first phase of a 65 MW/260 MWh battery storage system in southeastern Bulgaria, part of a larger 315 MW/760 MWh hybrid project with solar and wind components.
This marks one of Europe’s largest co-located storage systems, with the full project expected online by early next year.
