The international energy sector currently has a curious case study in an unlikely place: Bulgaria , a country in southeastern Europe with a population of just 6.4 million, now has one of the world's highest ratios of battery storage to total power capacity, outpacing markets like California, Germany and China .
In less than two years, Bulgaria's battery storage capacity has gone from zero to making up nearly a quarter of the country's total installed power capacity, fueled by EU funding and private capital worth close to €3 billion ($3.4 billion), according to calculations by Bulgaria's leading business publication Capital .
Bulgaria was lucky enough to escape the worst of the heatwaves and droughts that forced a cut in nuclear and hydro output in Hungary and Romania this summer.
During that period, it turned its batteries into a key grid stabilizer for neighboring markets and profited by storing cheap solar power and selling it in the evening when prices spike.
