Greece is increasingly supplying Bulgaria with electricity during the day, receiving stored energy back in the evening. In August, Bulgaria imported 750 MW from Greece and exported around 700 MW back at night. This trend highlights Bulgaria's growing capacity to store cheap solar energy for evening use. The share of solar energy in Bulgaria's electricity production rose from 4% in 2021 to 21% by 2026, supported by EU funds. Bulgaria's energy storage capacity now exceeds 16 GWh, allowing batteries to provide up to 30% of total electricity generation during peak times. The price difference between day and evening electricity consumption has decreased significantly, reflecting improved storage capabilities. Bulgaria also modernized its transmission network and opened its balancing market in 2025, enhancing connections with Greece and Romania. This shift has allowed Bulgaria to export more electricity to Romania, especially during peak demand periods.
