Bulgaria's battery storage capacity has doubled in a year to about 6 GW, supported by roughly €700 million in EU grants and regulatory changes that attracted private investment, industry and government figures cited by Reuters showed. [1]
Electricity exports rose 62% year on year to 3.5 TWh. Stored solar power helped supply neighbouring grids during summer heatwaves and reduced Romania's need to draw on hydropower after drought forced a nuclear-reactor shutdown. [1]
ContextThe figures describe installed capacity and system performance, not a new supply incident. Winter solar output, grid expansion needs and narrowing electricity-price spreads could limit the next phase of growth. [1]
